ABSTRACT

RESUMO Objetivo Avaliar a eficácia da trabeculotomia transluminal assistida por gonioscopia correlacionada com a gravidade do glaucoma. Métodos Análise restrospectiva de prontuários de pacientes que foram submetidos à trabeculotomia transluminal assistida por gonioscopia no período de 2019 a 2021 em um hospital privado. Resultados Vinte olhos foram submetidos à trabeculotomia transluminal assistida por gonioscopia (dois olhos) ou facectomia e trabeculotomia transluminal assistida por gonioscopia (18 olhos). Pacientes portadores da doença avançada obtiveram redução de 5mmHg (26,5%) na pressão intraocular, com redução de 2,3 drogas, e olhos com glaucoma leve ou moderado apresentaram redução de 8mmHg (40%) na pressão intraocular média e 2,1 drogas. Metade dos olhos operados teve hifema nos primeiros dias como principal complicação cirúrgica. Conclusão A trabeculotomia transluminal assistida por gonioscopia é um procedimento eficaz na redução da pressão intraocular e na redução da quantidade de drogas em uso, apresentando maior redução da pressão intraocular em olhos com glaucoma leve/moderado.


ABSTRACT Objective To evaluate efficacy of gonioscopy-assisted transluminal trabeculotomy and relate to severity of glaucoma. Methods A retrospective analysis of medical records of patients submitted to gonioscopy-assisted transluminal trabeculotomy, at a private hospital, from 2019 to 2021. Results A total of 20 were submitted to gonioscopy-assisted transluminal trabeculotomy (2 eyes) or facectomy and gonioscopy-assisted transluminal trabeculotomy (18 eyes). Patients with advanced-stage disease achieved a decrease by 5 mmHg (26.5%) in IOP, with a reduction of 2.3 drugs, and eyes with mild or moderate glaucoma showed a drop by 8 mmHg (40%) in mean IOP and of 2.1 drugs. Half of the operated eyes had hyphema in the first days as the main surgical complication. Conclusion Gonioscopy-assisted transluminal trabeculotomy is an effective procedure to reduce IOP and the number of drugs being used, with greater IOP decrease in eyes with mild/moderate glaucoma.

ABSTRACT

ABSTRACT Purpose To evaluate the cost-utility of the iStent inject® for the treatment of mild-to-moderate open-angle glaucoma (OAG) within the Brazilian Unified Health System (SUS). Methods A Markov model was developed, in which the effectiveness outcome measure was the incremental cost-effectiveness ratio (ICER: R$ / QALY quality-adjusted life-year). Direct medical costs were obtained from the SUS perspective. The base case comprised of a hypothetical cohort of patients with OAG using topical medication and being managed according to the Clinical Protocol and Therapeutic Guidelines (PCDT) and a real-world setting based on data from Datasus. The model's robustness through sensitivity analyses was tested. Results In the PCDT base case setting, the trabecular micro-bypass implant provided gains of 0.47 QALYs and an ICER of R$7,996.66/QALY compared to treatment with topical medication. In the real-world setting based on data from Datasus, the trabecular micro-bypass implant, provided gains of 0.47 QALYs and an ICER of R$4,485.68/QALY compared to treatment with topical medication. The results were robust to sensitivity analyses. Conclusion Incorporating iStent inject® to SUS provides an improvement in the patient's quality of life with an additional cost that warrants the benefit provided to patients. Results may be considered cost-effective compared to topical medication.


RESUMO Objetivo Avaliar a relação custo-utilidade do iStent inject® para o tratamento do glaucoma de ângulo aberto leve a moderado no Sistema Único de Saúde. Métodos Foi desenvolvido um modelo de Markov, no qual a medida de resultado de efetividade foi a razão custo-efetividade incremental (razão de custo-efetividade incremental: R$/ano de vida ajustado pela qualidade). Os custos médicos diretos foram obtidos por meio da perspectiva do Sistema Único de Saúde. O caso base foi composto de uma coorte hipotética de pacientes com glaucoma de ângulo aberto em uso de medicação tópica tratados de acordo com o Protocolo Clínico e Diretrizes Terapêuticas e um cenário do mundo real baseado em dados do Departamento de Informática do Sistema Único de Saúde. Foi testada a robustez do modelo por meio de análises de sensibilidade. Resultados No cenário base do Protocolo Clínico e Diretrizes Terapêuticas, o implante trabecular micro-bypass proporcionou ganhos de 0,47 ano de vida ajustado pela qualidade e razão de custo-efetividade incremental de R$7.996,66/ano de vida ajustado pela qualidade em relação ao tratamento com medicação tópica. No cenário real baseado em dados do Departamento de Informática do Sistema Único de Saúde, o implante trabecular proporcionou ganhos de 0,47 ano de vida ajustado pela qualidade e razão de custo-efetividade incremental de R$ 4.485,68/ano de vida ajustado pela qualidade em relação ao tratamento com medicação tópica. Os resultados foram robustos para análises de sensibilidade. Conclusão A incorporação do iStent inject® ao Sistema Único de Saúde proporciona melhora na qualidade de vida do paciente com um custo adicional que garante o benefício proporcionado a eles. Os resultados podem ser considerados custo-efetivos em comparação com a medicação tópica.

ABSTRACT

RESUMO Objetivo: Avaliar os resultados da facotrabeculectomia em seguimento igual ou superior a 5 anos. Métodos: Estudo retrospectivo, de intervenção e analítico realizado no centro cirúrgico da clínica de olhos de Juazeiro do Norte com pacientes operados no período de 2006 a 2013. Foram envolvidos na investigação 34 olhos de 29 pacientes com catarata senil e glaucoma primário de ângulo aberto submetidos à facotrabeculectomia. Foi criado um escore de risco de dano glaucomatoso variando de 0 a 5 ao avaliar pressão intraocular, escavação do disco óptico, número de drogas hipotensoras utilizadas para o tratamento do glaucoma e a idade do paciente em anos. A amostra foi de conveniência e pareada. Foi utilizado o teste de Wilcoxon pareado para a verificação de diferenças entre médias. Foi aceito p< 0,05 para a rejeição da hipótese de nulidade. O estudo foi aprovado pelo comitê de ética da plataforma Brasil e segue a resolução 466 do Conselho Nacional de Saúde. Resultados: A média da acuidade visual foi significantemente maior após o seguimento de 5 anos (média pré-operatória 0,42 +/- 0,23 ver-sus média pós-operatória 0,62 +/- 0,29 - p=0,0031). A média dos escores de risco para dano glaucomatoso após 5 anos de seguimento foi significativamente menor quando comparado ao pré-operatório (media pré-operatória: 9,47 +/- 1,61 versus média pós-operatória 6,55 +/- 2,21) p < 0,0001, considerado extremamente significante. Conclusão: A facotrabeculectomia foi significantemente efetiva na melhora da acuidade visual e na redução do risco de dano glau-comatoso após seguimento pós-operatório igual ou superior a 5 anos.


ABSTRACT Objective: To evaluate the results of phacotrabeculectomy in a follow-up of five years or more. Methods: Retrospective, interventional and analytical study that was carried out in the surgical center of clínica de olhos do juazeiro with patients operated on from 2006 to 2013. 34 eyes of 29 patients with senile cataract and primary open-angle glaucoma, who underwent phacotrabeculectomy were involved in the investigation. A risk score for glaucomatous dam-age ranging from 0 to 5 when evaluating intraocular pressure, excavation of the optic disc, number of hypotensive drugs used to treat glaucoma and the patient's age in years. The sample was of convenience and paired. The paired Wilcoxon test was used to verify differences be-tween means. P <0.05 was accepted for the rejection of the null hypothesis. The study was approved by the ethics committee of the Brazil platform and follows the principles of resolu-tion 466 of the National Health Council. Results: The mean visual acuity was significantly higher after a five-year follow-up (preoperative average 0.42 +/- 0.23 versus postoperative average 0.62 +/- 0.29 - p = 0.0031). The average risk score for glaucomatous damage after five years of follow-up was significantly lower when compared to the preoperative (preoperative mean: 9.47 +/- 1.61 versus postoperative mean 6.55 +/- 2, 21) p <0.0001, considered extremely significant. Conclusion: Phacotrabeculectomy was significantly effective in improving visual acuity and reducing the risk of glaucomatous damage after a five-year postoperative follow-up.

ABSTRACT

Objetivo: Describir los resultados visuales e hipotensores de la trabeculotomía gonioasistida modificada y determinar sus complicaciones. Métodos: Se realizó un estudio analítico de 30 ojos; 15 de ellos (15 pacientes) recibieron trabeculotomía gonioasistida modificada (grupo caso) y 15 ojos (15 pacientes) recibieron trabeculectomía con mitomicina C (control histórico). Resultados: Predominaron los pacientes masculinos. La edad promedio del grupo con trabeculectomía fue 64,2 ± 7,3 años; mientras la del grupo con trabeculotomía gonioasistida modificada fue 69,9 ± 4,8 años. La agudeza visual mejor corregida media preoperatoria fue menor en el grupo con trabeculectomía (95 VAR/100-80 vs. 97 VAR/100-90) y la presión intraocular media fue 26,0 mmHg/24,5-30,0) y 25,0 mmHg/22,5-27,0 respectivamente. Todos los pacientes con trabeculectomía recibieron 3 colirios hipotensores en el preoperatorio, mientras el 53,3 por ciento de los tratados con trabeculotomía gonioasistida modificada requirieron 3 colirios hipotensores. Al año, la agudeza visual mejor corregida media disminuyó en el grupo con trabeculectomía (90VAR/100-75), y se mantuvo en el grupo con trabeculotomía gonioasistida modificada (97VAR/100-90). En ambos grupos se produjo una caída significativa de la PIO promedio y más del 85 por ciento de los casos requirió uno o ningún colirio para su control. Conclusiones: El resultado visual, el poder hipotensor y las complicaciones quirúrgicas al año muestran la trabeculotomía gonioasistida modificada como una técnica útil y segura. Se requieren estudios a largo plazo para evaluar su efectividad futura(AU)


Objective: Describe results one year after modified gonioscopy-assisted trabeculotomy. Methods: An analytical study was conducted of 30 eyes, 15 of which (15 patients) underwent modified gonioscopy-assisted trabeculotomy (GATTm) (case group), and 15 trabeculotomy with mitomycin C (TBT) (historical control). Results: Male patients prevailed. Mean age was 64.2 ± 7.3 years for the TBT group and 69.9 ± 4.8 years for the GATTm group. In the TBT group mean preoperative best corrected visual acuity was lower (95 VAR/100-80 vs. 97VAR/100-90), whereas mean intraocular pressure was 26.0 mmHg/24.5-30.0 and 25.0 mmHg/22.5-27.0, respectively. All TBT patients received 3 hypotensive collyriums preoperative, while 53.3 percent of the GATTm patients required 3 hypotensive collyriums. At one year, mean best corrected visual acuity was lower in the TBT group (90VAR/100-75) and remained the same in the GATTm group (97VAR/100-90). A significant mean intraocular pressure reduction was observed in both groups and more than 85 percent of the cases required either one or no collyrium for their control. Conclusions: Visual result, hypotensive effect and surgical complications at one year are evidence that modified gonioscopy-assisted trabeculotomy is a safe, useful technique. Long-term studies are required to evaluate its future effectiveness(AU)

ABSTRACT

Se presenta una paciente femenina, de 52 años de edad, con antecedentes de asma bronquial, miopía y glaucoma juvenil diagnosticado a los 22 años de edad. Le fueron realizadas dos trabeculectomías en el ojo izquierdo y una en el ojo derecho. En el año 2008 se le realizó cirugía de facoemulsificación más implante de lente intraocular en ambos ojos. La paciente acudió a nuestro Servicio hace un año, y refirió disminución progresiva de la visión. El examen oftalmológico reveló agudeza visual mejor corregida de 0,4 y presión intraocular de 30 y 23,5 mm/Hg para los respectivos ojos, con terapia hipotensora máxima tolerable. Al fondo de ojo se observó daño glaucomatoso avanzado, mayor en ojo izquierdo. Como opción de tratamiento se realizó ciclofotocoagulación transescleral en 2 cuadrantes del ojo derecho. A los 6 meses se constató presión intraocular de 30 y 18 mm/Hg, y se decidió el implante de la válvula de Baervelt en el temporal superior del ojo derecho. En el posoperatorio a los 7 días el examen oftalmológico arrojó presión intraocular de 5 mm/Hg, atalamia grado III y agudeza visual mejor corregida de 0,2. Se prescribió tratamiento con midriático ciclopléjico y antinflamatorios tópicos y sistémicos, y se logró a los 15 días mejoría del cuadro ocular. Se obtuvo buena agudeza visual y presión intraocular de 12 mmHg a los 3 meses del posoperatorio. El dispositivo del drenaje de Baerveldt es eficaz para lograr la reducción de la presión intraocular en el glaucoma refractario(AU)


A case is presented of a female 52-year-old patient with a history of bronchial asthma, myopia and juvenile glaucoma diagnosed at age 22. Two trabeculectomies were performed on the left eye and one on the right eye. In the year 2008 the patient underwent phacoemulsification surgery plus intraocular lens implantation in both eyes. She attended our service a year ago, reporting progressive vision reduction. Ophthalmological examination revealed best corrected visual acuity of 0.4 and intraocular pressure of 30 and 23.5 mm/Hg for either eye, with maximum tolerated hypotensive therapy. Funduscopy showed advanced glaucomatous damage, greater in the left eye. The treatment option selected was transcleral cyclophotocoagulation in two quadrants of the right eye. At 6 months intraocular pressure was 30 and 18 mm/Hg, and it was decided to implant a Baerveldt valve in the upper temporal quadrant of the right eye. Ophthalmological examination results at 7 days postoperative were intraocular pressure 5 mm/Hg, grade III athalamia and best corrected visual acuity 0.2. The treatment indicated was a cycloplegic mydriatic and topical and systemic anti-inflammatories. Ocular status improvement was achieved at 15 days. Satisfactory visual acuity and an intraocular pressure of 12 mm/Hg were obtained at 3 months postoperative. The Baerveldt drainage device is effective to achieve intraocular pressure reduction in refractory glaucoma(AU)

ABSTRACT

El tratamiento del glaucoma se realiza con el objetivo de disminuir los niveles de presión intraocular, único factor tratable hasta el momento, y debe ser individualizado. Se presenta un paciente masculino de 54 años de edad, de piel mestiza, intelectual, con antecedentes de aparente salud y diagnóstico de glaucoma desde hace 10 años. Se realizó trabeculectomía con antimetabolito (mitomicina C) en el ojo izquierdo en el año 2012 por daño glaucomatoso avanzado. En el año 2016 acudió a nuestra consulta y refirió mala visión y descontrol de la presión intraocular de ambos ojos. Se constataron cifras muy elevadas de presión intraocular en ambos ojos, superiores a 30 mmHg; en el ojo derecho la unidad de visión con su mejor corrección y un daño campimétrico muy avanzado limitado a una isla de visión central con caída hasta los 5° centrales, y el ojo izquierdo no alcanzaba la percepción luminosa. Después de combinar 3 líneas farmacológicas con la dosis máxima, los valores de la presión intraocular no eran protectores. Surgió la disyuntiva entre realizar una cirugía filtrante, temiendo al riesgo quirúrgico elevado y tratándose de un ojo único, o no practicar cirugía alguna y solo continuar con el tratamiento farmacológico a pesar de no conseguirse valores de presión intraocular meta. Se decidió realizar esclerectomía profunda no penetrante con antimetabolito (mitomicina C al 0,02 por ciento). No se presentaron complicaciones asociadas y se consiguió el descenso de la presión intraocular a 24 mmHg, por lo que al mes de la cirugía se realizó goniopuntura. Se obtuvo la presión intraocular objetivo, sin progresión del daño glaucomatoso y hubo conservación de la agudeza visual(AU)


Treatment for glaucoma is aimed at reducing the levels of intraocular pressure. This is the only factor that may be treated so far, and it should be individualized. A case is presented of a male 54-year-old mulatto patient, intellectual, with a history of apparently good health who was diagnosed with glaucoma ten years ago. Trabeculectomy with antimetabolite (mitomycin C) was performed on the patient's left eye in the year 2012 due to advanced glaucomatous damage. In the year 2016 the patient attended our service and reported poor vision and uncontrolled intraocular pressure in both eyes. Very high intraocular pressure values above 30 mmHg were confirmed in both eyes. In the right eye the vision unit with its best correction, and very advanced campimetric damage limited to a central vision island with a fall to 5° central, whereas the left eye did not achieve light perception. After combining 3 drug lines at their maximum dosage, intraocular pressure values were not protective. The dilemma arose whether to perform filtration surgery, fearing the high surgical risk, being as it was a single eye, or not to perform any surgery and just go on with the drug treatment despite not having achieved target intraocular pressure values. It was decided to perform non-penetrating deep sclerectomy with antimetabolite (0.02 percent mitomycin C). No associated complications occurred and intraocular pressured fell to 24 mmHg. Therefore, goniopuncture was performed one month after surgery. The target intraocular pressure was obtained without glaucomatous damage progression and visual acuity was preserved(AU)

ABSTRACT

El glaucoma congénito primario constituye la forma más común de glaucoma infantil, el cual exige un diagnóstico precoz y un tratamiento quirúrgico relativamente urgente, ya que puede ocasionar graves secuelas morfológicas y funcionales. Se presenta la realización, por primera ocasión, de la trabéculo-trabeculectomía combinada en la República Democrática y Popular de Argelia. Se ejecutó en un paciente árabe, de un año de edad, a quien se le diagnosticó el glaucoma congénito primario II. Se evaluó el seguimiento posoperatorio con resultados satisfactorios, por lo que se consideró la trabéculo-trabeculectomía como el proceder quirúrgico efectivo y suficientemente seguro, el cual debe ser realizado por un personal calificado para poder admitirse como primera opción en el tratamiento quirúrgico del glaucoma congénito primario(AU)


Primary congenital glaucoma is the most common form of childhood glaucoma. This condition requires early diagnosis and relatively urgent surgical treatment, since it may leave serious morphological and functional sequelae. A description is provided of the first combined trabeculotomy-trabeculectomy performed in the People's Democratic Republic of Algeria. The operation was performed on a male one-year-old Arab patient diagnosed with primary congenital glaucoma II. Post-operative follow-up found satisfactory results, and trabeculotomy-trabeculectomy was thus considered to be an effective, sufficiently safe surgical procedure, which should be performed by qualified personnel to be accepted as the first surgical treatment option for primary congenital glaucoma(AU)

ABSTRACT

La cirugía filtrante es una opción de tratamiento encaminada a disminuir la presión intraocular una vez que no hay respuesta a las alternativas no quirúrgicas. En los últimos años ha experimentado una evolución sorprendente. Aparecen nuevos dispositivos que buscan obtener un control tensional con las mínimas complicaciones; entre estos, el implante Ex-PRESS ha demostrado una efectividad similar a la trabeculectomía, mientras que la variante técnica para su implantación, descrita por Richard Hoffmann, posibilita excelentes resultados con menos dificultades. Se presenta un paciente masculino de 51 años de edad, de raza blanca, con antecedente de glaucoma, con agudeza visual mejor corregida de 100 VAR y presión intraocular de 32 mmHg. Se realizó implante de dispositivo Ex-PRESS (modelo P-50) mediante la técnica modificada de Richard Hoffmann, asociada al uso de mitomicina C al 0,2 por ciento en el transoperatorio. A los dos años se lograron tensiones oculares de 17 mmHg y agudeza visual mejor corregida de 100 VAR(AU)


Filtration surgery is a therapeutic option aimed at reducing intraocular pressure when there is no response to non-surgical alternatives. Filtration surgery has developed remarkably in recent years. New devices have emerged geared to achieving pressure control with minimum complications. Among them, Ex-PRESS implantation has shown to be as effective as trabeculectomy, and the technique described by Richard Hoffman provides excellent results with fewer difficulties. A case is presented of a male white 51-year-old patient with a history of glaucoma, best corrected visual acuity 100 VAR, and intraocular pressure 32 mmHg. Implantation was performed of an Ex-PRESS (model P-50) device by modified Richard Hoffman's technique associated to 0.2 percent mitomycin C in the perioperative period. Two years after surgery, ocular tensions of 17 mmHg and a best corrected visual acuity of 100 VAR had been achieved(AU)

ABSTRACT

ABSTRACT Purpose: To compare changes in anterior segment parameters following ExPRESS Mini Glaucoma Shunt surgery vs. trabeculectomy using the Pentacam rotating Scheimpflug camera. Methods: In this prospective, comparative study, 27 patients with glaucoma treated at the Rabin Medical Center from 2009 to 2013 were enrolled in this prospective comparative study: 19 participants (19 eyes) underwent ExPRESS shunt implantation and 12 (13 eyes) underwent trabeculectomy. Changes in anterior chamber parameters at postoperative day 1 and postoperative month 3 were evaluated on Scheimpflug images. Results: Intraocular pressure decreased significantly from baseline in both groups. The decrease in both groups was similar at postoperative month 3 (p=0.82). ExPRESS surgery caused a transient increase in posterior corneal astigmatism (p=0.008) and a transient decrease in anterior chamber depth (p=0.016) and volume (p=0.006) on postoperative day 1. At postoperative month 3, these parameters were no longer statistically significant (p=0.65, p=0.51, and p=0.57 respectively). Trabeculectomy caused a transient increase in anterior and posterior corneal astigmatism on postoperative day 1 (p=0.003 and p=0.005, respectively), which were not evident at postoperative month 3 (p=1.0 and p=1.0, respectively). At postoperative month 3, both ExPRESS and trabeculectomy showed similar changes in anterior chamber parameters. Conclusions: Both ExPRESS mini glaucoma implant and trabeculectomy significantly decreased intraocular pressure and had transient effects on anterior segment parameters, with minor differences between the methods.


RESUMO Objetivo: Comparar as alterações nos parâmetros do segmento anterior após a cirurgia ExPRESS Mini Glaucoma Shunt vs. trabeculectomia usando a câmera Scheimpflug Pentacam rotativa. Métodos: Neste estudo comparativo prospectivo, 27 pacientes com glaucoma tratados no Centro Médico Rabin de 2009 a 2013 foram incluídos neste estudo comparativo prospectivo: 19 participantes (19 olhos) foram submetidos ao implante de derivação ExPRESS e 12 (13 olhos) foram submetidos à trabeculectomia. Alterações nos parâmetros da câmara anterior no dia 1 e em 3 meses de pós-operatório foram avaliadas pelas imagens de Scheimpflug. Resultados: A pressão intraocular diminuiu significativamente em relação aos valores iniciais nos dois grupos. A diminuição nos dois grupos foi semelhante no 3º mês pós-operatório (p=0,82). A cirurgia com ExPRESS causou um aumento temporário do astigmatismo posterior da córnea (p=0,008) e uma diminuição temporária da profundidade da câmara anterior (p=0,016) e do volume (p=0,006) no primeiro dia do pós-operatório. Ao final de três meses, esses parâmetros não foram mais estatisticamente significativos (p=0,065, p=0,51 e p=0,57, respectivamente). A trabeculectomia causou um aumento temporário do astigmatismo anterior e posterior da córnea no primeiro dia do pós-operatório (p=0,003 e p=0,005, respectivamente), mas isso não foi observado ao final de 3 meses (p=1,0 e p=1,0, respectivamente). Após 3 meses, tanto o EXPRESS quanto a trabeculectomia mostraram alterações semelhantes nos parâmetros da câmara anterior. Conclusões: O implante ExPRESS Mini para glaucoma e a trabeculectomia diminuíram significativamente a pressão intraocular e tiveram efeitos temporários nos parâmetros do segmento anterior, com pequenas diferenças entre os métodos.

ABSTRACT

Resumo Objetivo: Segunda maior causa de cegueira mundial, o glaucoma, ocasionalmente necessita de procedimento cirúrgico para controle. Tendo o Brasil um Sistema Único de Saúde (SUS), e crise político-econômica em 2016, objetiva-se avaliar o impacto financeiro na decisão terapêutica do glaucoma nos últimos 6 anos no Brasil, e considerar atual discussão sobre indicação de procedimentos intervencionistas precocemente no seu algoritmo terapêutico. Métodos: Estudo ecológico da população brasileira, com base no Sistema de Informações Hospitalares do SUS, avaliando comportamento temporal dos procedimentos cirúrgicos do SUS para tratamento do glaucoma, e variação do dólar como influenciador da tendência temporal sobre os procedimentos. Realizada a análise de Regressão Linear Simples, com significância estatística de P<0.05. Resultados: Entre 2013 e 2018 foram internados 24888 indivíduos por glaucoma, prevalência do sexo masculino (51.68%), brancos (32,57%) e idosos (57.84%). Regiões Sudeste (45.61%) e Nordeste (26.36%) com maior número de internações, sendo a Trabeculectomia (84,18%) principal procedimento realizado. Houve associação da Trabeculectomia e Implante de Válvula, individualmente e atrelados, com os valores do dólar nas regiões Centro-Oeste (β= 1,103 com P= 0,007 para Trabeculectomias e β= 1,105 com P=0,012 para ambos os procedimentos) e Sul (β= 16,727 e P= 0,006 para os Implantes), e associação entre aumento de Implantes na região Sul e maior cobertura na atenção básica (β= 0.64 e P= 0.009). Conclusão: Observou-se não interferência do dólar, e aumento dos procedimentos na região Sul e Centro-Oeste. Os resultados corroboram tendência intervencionista, podendo ser representada pelo possível uso dos procedimentos disponibilizados pelo SUS de forma precoce.


Abstract Objective: The second leading cause of blindness worldwide, glaucoma, occasionally requires surgical procedure for control. Given that Brazil has an Unified Health System (SUS) and a political-economic crisis in 2016, we aim to evaluate the financial impact on the therapeutic decision of glaucoma in the last 6 years in Brazil, and to consider the current discussion about early interventionist indication in its therapeutic algorithm. Methods: Ecological study of the Brazilian population, based on the SUS Hospital Information System, evaluating the temporal behavior of SUS surgical procedures on glaucoma treatment, and dollar variation as influencing the temporal trend on the procedures. Simple Linear Regression analysis was performed, with statistical significance of P <0.05. Results: Between 2013 and 2018, 24888 individuals were hospitalized for glaucoma, male prevalence (51.68%), whites (32.57%) and elderly (57.84%). Southeast (45.61%) and Northeast (26.36%) Regions with the largest number of hospitalizations, and Trabeculectomy (84.18%) being the main procedure performed. There was an association of trabeculectomy and valve implantation, individually and linked, with dollar values in the Midwest (β = 1.103 with P = 0.007 for Trabeculectomies and β = 1.105 with P = 0.012 for both procedures) and South (β). = 16,727 and P = 0,006 for Implants), and association between increased Implants in the South region and greater coverage in primary care (β = 0.64 and P = 0.009). Conclusion: Non-dollar interference was observed, and increased procedures in the South and Midwest. The results corroborate an interventionist tendency and may be represented, possible, by the use of procedures provided by the SUS in an early manner.

ABSTRACT

RESUMEN Objetivo: Determinar los resultados de la facotrabeculectomía por dos vías como tratamiento combinado de pacientes cubanos con glaucoma y catarata. Métodos: Se realizó un estudio observacional descriptivo longitudinal prospectivo en pacientes adultos cubanos tratados con facotrabeculectomía en el Servicio de Glaucoma del Instituto Cubano de Oftalmología "Ramón Pando Ferrer" entre junio del año 2016 y abril de 2017. El universo estuvo constituido por todos los pacientes operados con facotrabeculectomía por dos vías. La muestra la integraron pacientes operados por un mismo cirujano, quienes estuvieron de acuerdo con participar en la investigación. Se excluyeron aquellos con cirugía intraocular previa. Salieron del estudio los que no pudieron mantener el seguimiento en la institución. Se estudiaron las variables edad, sexo, color de la piel, agudeza visual mejor corregida, presión intraocular, número de medicamentos hipotensores oculares y complicaciones presentadas. El seguimiento fue por dos años con consultas al día siguiente, a los siete y a los treinta días; a los tres y a los seis meses; al año y a los dos años. Resultados: Se observaron 31 pacientes. La edad promedio fue de 70 años, con predominio del sexo femenino y el color de la piel no blanco; la agudeza visual mejor corregida preoperatoria media 0,58 y la posoperatoria 0,73. La presión intraocular media preoperatoria 22,04 mmHg y a los dos años 16,37 mmHg. La media de los medicamentos hipotensores preoperatorios fue 3,0 y 0,3 a los dos años. Las complicaciones más frecuentes resultaron la ruptura transquirúrgica de la cápsula posterior y la opacidad posquirúrgica de la cápsula posterior. Conclusiones: Con la facotrabeculectomía por dos vías disminuye la presión intraocular; mejora la agudeza visual mejor corregida y se reduce el número de fármacos hipotensores oculares al menos durante dos años. Las complicaciones asociadas a la técnica son mínimas(AU)


ABSTRACT Objective: Determine the results of two-site phacotrabeculectomy as combined therapy for Cuban patients with glaucoma and cataract. Methods: An observational prospective longitudinal descriptive study was conducted of Cuban patients undergoing phacotrabeculectomy at the Glaucoma Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from June 2016 to April 2017. The study universe was all the patients undergoing two-site phacotrabeculectomy. The sample was patients operated on by the same surgeon who consented to participate in the research. Patients with a history of intraocular surgery were excluded, as well as those who could not be followed up at the institution. The variables considered were age, sex, skin color, best corrected visual acuity, intraocular pressure, number of ocular hypotensive drugs, and complications developed. Follow-up extended for two years with visits on the next day, at seven and thirty days, at three and six months, and at one and two years. Results: Thirty-one patients were observed. Mean age was 70 years, with a predominance of the female sex and non-white skin color. Best corrected visual acuity was 0.58 preoperative and 0.73 postoperative. Mean preoperative intraocular pressure was 22.04 mmHg, whereas at two years it was 16.37 mmHg. Hypotensive drugs averaged 3.0 preoperative and 0.3 at two years. The most common complications were intraoperative posterior capsule rupture and postsurgical posterior capsule opacity. Conclusions: Two-site phacotrabeculectomy reduces intraocular pressure, improves best corrected visual acuity and lowers the number of ocular hypotensive drugs for at least two years. The complications associated to the technique are minimum(AU)

ABSTRACT

ABSTRACT Purpose: Our initial goal was to compare the efficacy and safety of a glaucoma drainage device and trabeculectomy for children with primary congenital glaucoma after angular surgery failure. However, we discontinued the study due to the rate of complications and wrote this report to describe the results obtained with the two techniques in this particular group. Methods: This was a parallel, non-masked, controlled trial that included patients aged 0-13 years who had undergone previous trabeculotomy or goniotomy and presented inadequately controlled glaucoma with an intraocular pressure ≥21 mmHg on maximum tolerated medical therapy. We randomized the patients to undergo either placement of a 250-mm2 Baerveldt glaucoma implant or mitomycin-augmented trabeculectomy. The main outcome measure was intraocular pressure control. We calculated complete success (without hypotensive ocular medication) and qualified success (with medication) rates. We defined failure as uncontrolled intraocular pressure, presence of serious complications, abnormal increase in ocular dimensions, or confirmed visual acuity decrease. Results: We studied 13 eyes of 13 children (five in the glaucoma drainage device group; eight in the trabeculectomy group). Both surgical procedures produced a significant intraocular pressure reduction 12 months after intervention from the baseline (tube group, 22.8 ± 5.9 mmHg to 12.20 ± 4.14 mmHg, p=0.0113; trabeculectomy group, 23.7 ± 7.3 mmHg to 15.6 ± 5.9 mmHg, p=0.0297). None of the patients in the tube group and 37.5% of those in the trabeculectomy group achieved complete success in intraocular pressure control after 12 months of follow-up (p=0.928, Chi-square test). Two patients (40%) had serious complications at the time of tube aperture (implant extrusion, retinal detachment). Conclusions: Both the tube and trabeculectomy groups presented similar intraocular pressure controls, but complete success was more frequent in the trabeculectomy group. Non-valved glaucoma drainage devices caused potentially blinding complications during tube opening. Because of the small sample size, we could not draw conclusions as to the safety data of the studied technique.


RESUMO Objetivo: O objetivo inicial era comparar a eficácia e a segurança do implante de drenagem e a trabeculectomia em crianças com glaucoma congênito primário após falência de cirurgia angular. Como o estudo foi descontinuado devido à taxa de complicações, o objetivo deste artigo foi descrever os resultados das duas técnicas neste grupo específico. Métodos: Ensaio clínico randomizado, não mascarado, incluindo pacientes com idade de 0 a 13 anos previamente submetidos à goniotomia ou trabeculotomia. Os pacientes, que apresentavam glaucoma não controlado com pressão intraocular ≥21 mmHg em terapia medicamentosa máxima, foram randomizados para o implante de drenagem de Baerveldt 250 mm2 (Grupo Tubo) ou trabeculectomia com mitomicina (grupo TREC). O principal desfecho avaliado foi o controle da pressão intraocular. Sucesso completo (sem medicação ocular hipotensora) e sucesso qualificado (com medicação) foram descritos. A falência foi baseada na pressão intraocular não controlada, presença de complicações sérias, aumento anormal das dimensões oculares e diminuição confirmada da acuidade visual. Resultados: Treze olhos de 13 crianças foram estudados (cinco no grupo Tubo e oito no grupo TREC). Ambos os procedimentos reduziram a pressão intraocular em relação às medidas iniciais após 12 meses da intervenção (grupo Tubo 22.8 ± 5.9 mmHg para 12.20 ± 4.14 mmHg, p=0.0113; grupo TREC, 23.7 ± 7.3 mmHg para 15.6 ± 5.9 mmHg, p=0.0297). Nenhum paciente no grupo Tubo e 37.5% do grupo TREC alcançaram o sucesso completo após 12 meses de acompanhamento (p=0.928, teste qui-quadrado). Dois pacientes (40%) apresentaram sérias complicações no momento da abertura do tubo (extrusão do implante e descolamento de retina). Conclusão: Os dois grupos estudados apresentaram resultados semelhantes quanto ao controle da pressão intraocular, mas o sucesso completo foi mais frequente no grupo da trabeculectomia. Implantes de drenagem não valvulados podem cursar com potenciais complicações visuais no momento da abertura do tubo. Devido ao pequeno tamanho da amostra, não foi possível determinar quaisquer dados de segurança conclusivos em relação à técnica estudada.

ABSTRACT

PURPOSE: To report a case of Epstein-Barr virus-related corneal endotheliitis accompanied by secondary glaucoma.CASE SUMMARY: A 73-year-old male presented with blurred vision in his right eye. In the ophthalmic evaluation, there were dispersed keratic precipitates overlying corneal edema. The anterior chamber showed trace ~1+ graded inflammation and an endothelial density decrease. His best-corrected visual acuity and intraocular pressure in the right eye were 0.2 and 34 mmHg, respectively. Paracentesis was performed on the anterior chamber of the right eye to confirm the diagnosis under the suspicion of corneal endotheliitis with trabeculectomy for the intraocular pressure control. Epstein-Barr virus was confirmed using a multiplex polymerase chain reaction (PCR), and oral and eye drops of Acyclovir were used to treat the patient. There was no evidence of a recurrence over 2 years and his intraocular pressure was 12 mmHg and best-corrected visual acuity was maintained at 0.5.CONCLUSIONS: A case of Epstein-Barr virus-related corneal endotheliitis was diagnosed using PCR of the aqueous humor. The patient was treated with an oral antiviral agent and eyedrops without a recurrence.

ABSTRACT

PURPOSE: We report a case of Urrets-Zavalia syndrome with a fixed dilated pupil after an uneventful trabeculectomy.CASE SUMMARY: Trabeculectomy was performed on a 51-year-old male who had a history of recurrent uveitis in the left eye, with uncontrolled intraocular pressure despite maximally-tolerated medial therapy. There was no unexpected event during surgery. Topical 1% atropine was used for only 2 days after surgery. In the early postoperative period, 1% prednisolone and 0.3% ofloxacin were given four times a day, then gradually reduced. One month later, only 1% prednisolone was given once a day. Intraocular pressure in his left eye was well controlled from 8–14 mmHg after surgery. One month after surgery, the pupils remained dilated. There was no reaction to topical 2% pilocarpine and no relative afferent pupillary defect or posterior synechia.CONCLUSIONS: Our case, although rare, suggests that Urrets-Zavalia syndrome should be considered in patients with well-controlled intraocular pressure after uneventful trabeculectomy.

ABSTRACT

RESUMEN Se realiza una actualización sobre el diagnóstico y tratamiento del glaucoma infantil primario, considerando la importancia que tiene un diagnóstico precoz y un tratamiento oportuno para obtener los mejores resultados posibles. Actualmente, a pesar del surgimiento de nuevos fármacos y de técnicas quirúrgicas para tratar esta afección, aún existen discrepancias sobre cómo debemos realizar el diagnóstico positivo; qué tratamiento o técnica quirúrgica emplear; cuándo y cuál sería la mejor. Cuando se trata de glaucoma pediátrico (primario o secundario), presente en etapas tan tempranas de la vida -incluso al nacimiento, donde la cirugía está indicada lo más precozmente posible, con la disyuntiva de cuáles medicamentos podemos emplear o no, por desconocimiento de qué efectos indeseables pudieran presentarse en estas edades y además, teniendo en cuenta que estos niños serán nuestros pacientes para toda la vida- es necesario conocer y repasar una vez más este tema. Se recomienda instruir a pediatras y oftalmólogos generales para lograr la remisión adecuada y precoz del niño a un centro especializado para su tratamiento quirúrgico, y mejorar así su pronóstico visual(AU)


ABSTRACT Updated information is provided about the diagnosis and treatment of primary childhood glaucoma, given the importance of early diagnosis and timely treatment to obtain the best possible results. Despite the emergence of new drugs and surgical techniques to treat this disorder, there is still controversy about how we should perform the positive diagnosis, what treatment or surgical technique should be used and when, and which would be the best. When childhood glaucoma (whether primary or secondary) presents at early stages of life - even at birth -, in which case surgery should be indicated as soon as possible, we are faced with the dilemma of what drugs we may or may not use, due to lack of knowledge about undesirable effects which could appear at these ages, and bearing in mind that these children will be our patients for a lifetime. It is thus necessary to be informed about this topic and go over it once again. It is recommended to instruct pediatricians and ophthalmologists to ensure timely, appropriate referral of the child patient to a specialized center where they will receive surgical treatment, thus improving their visual prognosis(AU)

ABSTRACT

Resumo A matriz de colágeno Ologen TM é um novo agente antifibrótico composto por uma matriz porosa de atelocolageno tipo I e glicosaminoglicanos reticulados, que pode ser utilizado como uma alternativa para a modulação da cicatrização nas cirurgias. Por ser altamente poroso e biodegradável, este implante auxilia nos processos de reparação fisiológicos que ocorrem no tecido conjuntivo e epitelial da lesão, sem a formação de tecido fibrótico, o qual acarreta insucesso cirúrgico e elevação da PIO. A Trabeculectomia (TREC) é considerada a cirurgia padrão para o tratamento do glaucoma, no entanto as taxas de sucesso cirúrgico a médio e longo prazo estão relacionadas a cicatrização do sítio operatório, envolvendo principalmente o tecido conjuntival e tenoniano. O processo de cicatrização é divido em 4 fases principais: coagulativa, inflamatória, proliferativa e remodeladora, com uma série de cascatas químicas e fatores bioquímicos liberados na tentativa de restabelecer a hemostasia. Diversas pesquisas na literatura já demonstraram os efeitos benéficos na cicatrização ao utilizar a matriz de colágeno Ologen em cirurgias oftalmológicas, além das possíveis complicações. Os resultados dos atuais estudos com implante de Ologen para o tratamento de glaucoma são encorajadores e promissores. No entanto, ensaios clínicos randomizados futuros com seguimento a longo prazo são necessários para avaliarmos a segurança e a eficácia do novo implante na modulação da cicatrização, alcançando melhores taxas de sucesso cirúrgico.


Abstract The Ologen™ collagen matrix is a new antifibrotic agent composed of a porous matrix of type I atelocolagene and cross-linked glycosaminoglycans, which can be used as an alternative for the modulation of healing in surgeries. Because it is highly porous and biodegradable, this implant assists in the physiological repair processes that occur in the connective and epithelial tissue of the lesion without the formation of fibrotic tissue, which leads to surgical failure and IOP elevation. The Trabeculectomy (TREC) is considered the standard surgery for the treatment of glaucoma; however, the surgical success rates in the medium and long term are related to surgical site healing, mainly involving conjunctival and tenonian tissue. The healing process is divided into 4 main phases: coagulative, inflammatory, proliferative and remodeling, with a series of chemical cascades and biochemical factors released in an attempt to restore hemostasis. Since several researches in the literature have already demonstrated the beneficial effects on healing by using the Ologen collagen matrix in ophthalmic surgeries, in addition to possible complications. The results of current Ologen implant studies for the treatment of glaucoma are encouraging and promising. However, future randomized clinical trials with long-term follow-up are necessary to evaluate the safety and efficacy of the new implant in modulating healing, achieving better rates of surgical success.
