ABSTRACT

El trauma ocular constituye la causa de pérdida ocular más frecuente a nivel mundial y puede presentarse en cualquier etapa de vida, con mayor incidencia en la niñez. El manejo puede ser quirúrgico, quirúrgico-protésico o protésico. A continuación, se presenta un caso clínico que describe la rehabilitación protésica individualizada posterior a una evisceración en una lesión ocular unilateral traumática de hace aproximadamente 56 años, que presenta ptosis del párpado superior, colapso y atrofia muscular debido a la falta de función. Se describe la técnica de confección de los conformadores oculares para corregir la ptosis del párpado superior y lograr la expansión gradual de la cavidad, así como la confección de la prótesis ocular individualizada, con el objetivo de alcanzar los requerimientos funcionales y estéticos esperados. (AU)


Ocular trauma is the most frequent cause of eye loss worldwide. It can occur at any stage of life, with a higher incidence in childhood. Management can be surgical, surgical - prosthetic or prosthetic. We describe individualized prosthetic rehabilitation in a clinical case of upper eyelid ptosis, collapse and muscle atrophy due to lack of function following evisceration in a traumatic unilateral ocular injury approximately 56 years previously. We describe the technique for making ocular shapers to correct ptosis of the upper eyelid and achieve gradual expansion of the cavity, as well as the preparation of an ocular prosthesis to fulfill the expected functional and esthetic requirements.

ABSTRACT

ABSTRACT We present a patient who underwent evisceration surgery after spontaneous rupture of the ocular globe due to long-data uncontrolled glaucoma, with posterior placement of an orbital implant made of a bone cement compound based on polymethylmethacrylate as alternative materials were not available. Such a compound is characterized by excellent biocompatibility and low cost, which makes it an interesting alternative for treatment. The anophthalmic socket was successfully filled, providing proper esthetic results and favorable conditions for the posterior scleral prosthesis implantation. No complications were observed during 10 months of follow-up. We believe that, in the absence of alternative materials, low-cost materials may be used in emergency settings to repair anophthalmic cavities and provide satisfactory functional and esthetic outcomes.


RESUMO Apresentamos um paciente que foi submetido à cirurgia de evisceração após ruptura espontânea do globo ocular devido a glaucoma não controlado de longa data, com posterior colocação de implante orbital feito de cimento ósseo, composto à base de polimetilmetacrilato, diante da indisponibilidade de materiais alternativos. Tal composto se caracteriza pela excelente biocompatibilidade e baixo custo, o que o torna uma alternativa interessante para o tratamento. A cavidade anoftálmica foi preenchida com sucesso, fornecendo resultados estéticos adequados e condições favoráveis para o implante posterior de prótese escleral. Nenhuma complicação foi observada durante os 10 meses de seguimento. Acredi­tamos que, na ausência de materiais alternativos, materiais de baixo custo podem ser usados em situações emergenciais para preencher cavidades anoftálmicas e prover resultados funcionais e estéticos satisfatórios.

ABSTRACT

ABSTRACT Purpose: To evaluate the biocompatibility of three-dimensional (3D) printed orbital spheres for evisceration. Materials: A total of 10 consecutive patients (eight females and two males; mean age, 46.8 ± 14.2 years) underwent evisceration of blind painful eyes. 3D spherical implants produced by a rapid prototype machine were used to restore orbital volume. The implants were produced from a commercially available photocurable resin (Fullcure®). Systemic toxicity was evaluated by comparing serum biochemical measurements (creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase, albumin, creatinine, urea, alkaline phosphatase, and C-reactive protein) before and at 12 months after surgery. Local toxicity was assessed by the evaluation of signs of socket inflammation at the first postoperative month. Changes in implant size were determined by computed tomography scans at 2 and 12 months after surgery. Results: The postoperative evaluations were uneventful. The biochemical evaluation showed no significant changes after surgery. None of the patients presented signs of orbital implant inflammation, infection, exposure, or extrusion. Computed tomography scan evaluations revealed no changes in implant size. Conclusion: To the best of our knowledge, this is the first phase-1 clinical study to certify the biocompatibility of the Fullcure resin for orbital implants in humans. The 3D printing technology permits fast and accurate production of implants for this purpose.


RESUMO Objetivos: Avaliar a biocompatibilidade das esferas produzidas por impressora tridimensional em evisceração. Pacientes e métodos: Evisceração por olho cego doloroso foi realizada em 10 pacientes consecutivos (8 mulheres, idade média: 46.8 ± 14.2 anos). Os implantes esféricos foram produzidos pelo sistema de prototipagem rápida utilizando dados tridimensionais computadorizados. O material utilizado para produção dos implantes foi a resina fotocurável Fullcure®. A avaliação da toxicidade sistêmica do material foi realizada por meio da dosagem de marcadores bioquímicos (creatina fosfoquinase, aspartato aminotransferase, alanina aminotransferase, albumina, creatinina, ureia, fosfatase alcalina, e proteína C-reactiva) antes da cirurgia e aos 12 meses de pós-operatorio. A avaliação da toxicidade local foi realizada por meio do registro qualitativo dos sinais inflamatórios no lado operado durante o primeiro mês de pós-operatório. O tamanho dos implantes foi medido em tomografias computadorizadas (CT) aos 2 e 12 meses de pós-operatório. Resultados: A avaliação bioquímica mostrou que os marcadores estudados não sofreram alterações significativas após a cirurgia. Nenhum paciente apresentou sinais de inflamação atípica, infecção, exposição ou extrusão. A avaliação tomográfica não demonstrou mudanças nos tamanhos dos implantes. Conclusão: O presente trabalho é o primeiro estudo clínico realizado para atestar a biocompatibilidade dos implantes orbitais de resina fotocurável Fullcure. A produção dos implantes pela técnica de impressão tridimensional, utilizando essa resina, permite a disponibilização rápida e acurada do produto final

ABSTRACT

ABSTRACT Purpose: To evaluate peripapillary choroidal thickness changes in contralateral eyes of patients who had undergone evisceration of their diseased eyes. Methods: In this retrospective study, peripapillary choroidal thickness parameters in 34 eyes of 34 patients who had undergone diseased-eye evisceration between March 2014 and May 2016 were evaluated using spectral domain optical coherence tomography. The scans were manually delineated to identify the principal surfaces of Bruch's membrane, the Bruch's membrane opening, and the anterior sclera. Peripapillary choroidal thickness was measured between the Bruch's membrane and the anterior sclera at increasing distance away from the Bruch's membrane opening. The mean peripapillary choroidal thickness values in the contralateral eyes of the patients and those of the control group were compared. Results: The mean peripapillary choroidal thickness was higher in the contralateral eyes of the patients compared with that of normal eyes at all distances from the Bruch's membrane opening. Conclusion: Increased peripapillary choroidal thickness was noted in the contralateral eyes of the patients, potentially resulting in a thicker choroid. Although further investigation is required to determine the cause, these findings indicate the presence of a compensatory factor in the contralateral eyes.


RESUMO Objetivo: Avaliar as alterações da espessura coroide peripapilar em olhos contralaterais de pacientes submetidos à evisceração do olho doente. Métodos: Neste estudo retrospectivo, parâmetros da espessura coróide peripapilar de 34 olhos de 34 pacientes submetidos à evisceração, entre março de 2014 e maio de 2016, foram avaliados com tomografia de coerência óptica de domínio espectral. As varreduras foram manualmente delineadas para identificar as principais superfícies da membrana de Bruch, a abertura da membrana de Bruch e a esclera anterior. A espessura coroide peripapilar foi medida entre a membrana de Bruch e a esclera anterior a uma distância crescente da abertura da membrana de Bruch. Compararam-se os valores médios da espessura coroide peripapilar dos olhos contralaterais dos pacientes e do grupo controle. Resultados: A espessura coroide peripapilar média foi mais espessa nos olhos contralaterais dos pacientes, quando comparada com os olhos normais, em todas as distâncias da abertura da membrana de Bruch. Conclusão: O aumento da espessura coroide peripapilar foi notado nos olhos contralaterais dos pacientes. O espessamento da coroide pode ser resultante do distúrbio. Embora seja necessária uma investigação mais aprofundada para determinar a causalidade, esses achados podem apontar para um fator compensatório dos olhos contralaterais.

ABSTRACT

ABSTRACT Bilateral simultaneous cataract surgery (BSCS) has gained popularity among eye surgeons in many countries. This study examines the case of a 77-year-old patient who developed bilateral Pseudomonas aeruginosa endophthalmitis following bilateral simultaneous cataract surgery. Immediate bilateral vitrectomy and intravitreal antibiotics injection were performed. Ultimately, both eyes were eviscerated due to pain refractory to treatment and no light perception.


RESUMO A cirurgia bilateral simultânea de catarata ganhou popularidade entre cirurgiões oftalmológicos em muitos países. Este estudo examina o caso de um paciente de 77 anos que desenvolveu endoftalmite bilateral por Pseudomonas aeruginosa após uma cirurgia bilateral simultânea de catarata. Vitrectomia bilateral imediata e injeção de antibióticos intravítreos foram realizadas. Em última análise, ambos os olhos foram eviscerados devido à dor refratária ao tratamento e sem percepção de luz.

ABSTRACT

ABSTRACT Purpose: To analyze the indications and types of eye removal at Latin America's highest-volume ophthalmic reference center in São Paulo, Brazil. Methods: A retrospective analysis was conducted of surgical pathological reports in the electronic database of the Ophthalmology Department of the Universidade Federal de São Paulo Hospital of patients who underwent eye-removal procedures between January 2000 and December 2012. Results: A total of 412 cases met the inclusion criteria for this study. The most common indications for eye removal were ocular melanoma and retinoblastoma, representing 35.4% and 31.1% of the total cases, respectively. Other frequent indications included endophthalmitis (6.3%), nonspecific inflammation (4.1%), squamous cell carcinoma (3.6%), panophthalmitis (3.4%), and phthisis bulbi (1.2%). The remaining indications accounted for 14.8% of all cases, with each accounting for <1% of the total cases. Enucleation was the most common eye-removal procedure seen in our study. Conclusions: The two most common indications for eye removal were ocular melanoma and retinoblastoma. Alternative treatment options are effective in limiting the need for eye removal but are constrained by our public center's so cioeconomic context.


RESUMO Objetivo: Analisar os tipos e indicações para a remoção dos olhos no maior centro de referência oftalmológica da América Latina em São Paulo, Brasil. Métodos: Revisão retrospectiva de laudos cirúrgico patológico em uma base de dados eletrônica do Departamento de Oftalmologia do Hospital da Universidade Federal de São Paulo. Foram analisados pacientes submetidos ao procedimento de remoção oftálmica no período de janeiro de 2000 a dezembro de 2012. Resultados: Um total de 412 casos estiveram de acordo com os critérios de inclusão desse estudo. A indicação mais comum para remoção oftálmica foi Melanoma ocular e Retinoblastoma, representando, respectivamente, 35,4% e 31,1% do total de casos. Outras indicações frequentes incluíam Endoftalmite 6,3%, Inflamação inespecífica 4,1%, Carcinoma escamocelular 3,6%, Panoftalmite 3,4% e Phthisis Bulbi 1,2%. O restante das indicações totalizaram 14,8% de todos os casos, sendo que cada um correspondem com menos de 1% do total. Enucleação foi o procedimento de remoção oftálmica mais comum observado em nosso estudo. Conclusão: As duas indicações mais frequentes para remoção oftálmica no centro oftalmológico de referência do Brasil foi melanoma e retinoblastoma. Opções terapêuticas alternativas são efetivas para limitar a necessidade da remoção ocular, porém são restritos devido ao contexto socioeconômico de nossa população.

ABSTRACT

ABSTRACT Purpose: The purpose of this study was to determine the indications and frequency of evisceration after penetrating keratoplasty (PK). Methods: The medical records of all patients who underwent evisceration after PK between January 1, 1995 and December 31, 2015 at Ankara Training and Research Hospital were reviewed. Patient demographics and the surgical indications for PK, diagnosis for evisceration, frequency of evisceration, and the length of time between PK and evisceration were recorded. Results: The frequency of evisceration was 0.95% (16 of 1684), and the mean age of the patients who underwent evisceration was 56.31 ± 14.82 years. The most common indication for PK that resulted in evisceration was keratoconus (37.5%), and the most common underlying cause leading to evisceration was endophthalmitis (56.25%). The interval between PK and evisceration ranged from 9 to 78 months. Conclusions: Although keratoplasty is one of the most successful types of surgery among tissue transplantations, our findings show that it is associated with a possible risk of evisceration.


RESUMO Objetivo: O objetivo deste estudo foi determinar as indicações e a frequência de evisceração ocular após cirurgia de ceratoplastia penetrante ou transplante de córnea (PK). Métodos: Foram analisados os registros médicos de todos os pacientes submetidos à evisceração após PK entre 1º de janeiro de 1995 e 31 de dezembro de 2015 no Hospital de Treinamento e Pesquisa de Ankara. Foram registradas a demografia do paciente e as indicações cirúrgicas de PK, diagnóstico de evisceração, frequência de evisceração, tempo entre PK e evisceração. Resultados: A frequência de evisceração foi de 0,95% (16 de 1684) e a média de idade foi de 56,31 ± 14,82 anos. A indicação mais comum para PK que terminou na evis ceração foi o ceratocone (37,5%) e a causa subjacente à evisceração foi a endoftalmite (56,25%). O intervalo entre PK e evisceração variou de 9 a 78 meses. Conclusão: Embora a ceratoplastia seja uma das cirurgias mais bem sucedidas entre os transplantes de tecidos, pode-se deduzir do estudo que não é tão inócua, pois pode evoluir para a evisceração ocular.

ABSTRACT

Introduction : La chirurgie mutilante du globe oculaire se définit par l'ablation chirurgicale du globe oculaire ou bien de son contenu. Notre étude a pour but d'étudier le profil épidémio-clinique de la chirurgie mutilante du globe oculaire au CHU-JRA.Matériels et méthodes : Il s'agit d'une étude rétrospective, descriptive sur 4 ans et demi, allant de janvier 2009 à juillet 2013 incluant tous les patients ayant subi une amputation du globe oculaire avec un dossier complet et enregistrés dans le registre du bloc opératoire. Résultats : Nous avons retenu 38 cas, soit 1,65% des activités chirurgicales du service. L'âge moyen était de 17,50. Le sex-ratio était de 1,11. Les 68,42% de nos patients venaient d'un milieu rural. Le délai de consultation moyen est de 25 jours. Les indications chirurgicales étaient le rétinoblastome dans 28,95%. L'éviscération a été pratiquée chez 27 patients, l'énucléation chez 10 patients et l'exentération chez un patient. Discussion : Le choix de la technique chirurgicale est différent d'une étude à l'autre et est fonction des indications. Conclusion : Une éducation de la population et une bonne prise en charge des pathologies oculaires permettent de limiter la chirurgie mutilante du globe oculaire

ABSTRACT

The purpose of this study was to evaluate acrylonitrile butadiene styrene (ABS) and polyamide implants in rabbits submitted to evisceration at the macroscopic and microstructure level and to assess clinical response and histopathological changes as well. For the experimental study implants of 12mm diameter were prepared by rapid prototyping, weighed and the outer and inner surfaces evaluated macroscopically and by electron microscopy. In addition, a compression test was performed and ultrastructural damage was then determined. After evisceration of the left eyeball, nine New Zealand rabbits received ABS implants and nine others received polyamide implants. The animals were assessed daily for 15 days after surgery and every seven days until the end of the study (90 days). Histopathological evaluation was performed at 15, 45 and 90 days after surgery. The ABS implants weighed approximately 0.44g, while the polyamide ones weighed 0.61g. Scanning electron microscopy demonstrated that the ABS implants had regular-sized, equidistant micropores, while the polyamide ones showed micropores of various sizes. The force required to fracture the ABS implant was 14.39 ±0.60 Mpa, while for the polyamide one, it was 16.80 ±1.05 Mpa. Fifteen days after surgery, we observed centripetal tissue infiltration and scarce inflammatory infiltrate. Implants may be used in the filling of anophthalmic cavities, because they are inert, biocompatible and allow tissue integration.(AU)


Avaliou-se a macroscopia, a microestrutura, a resposta clínica e histopatológica de implantes de acrilonitrila butadieno estireno (ABS) e poliamida em coelhos submetidos à evisceração. Para o estudo experimental, os implantes foram elaborados por meio de prototipagem rápida, com 12mm de diâmetro, pesados e tiveram suas superfícies avaliadas macroscopicamente e por microscopia eletrônica de varredura. Adicionalmente, foi realizado ensaio de compressão para determinar a força necessária para fraturar os implantes. Após a evisceração do olho esquerdo, nove coelhos da raça Nova Zelândia receberam implantes de poliamida e nove outros receberam implantes de ABS. Os animais foram avaliados diariamente nos primeiros 15 dias após a cirurgia e a cada sete dias até o fim do período experimental (90 dias). Avaliação histopatológica foi realizada aos 15, 45 e 90 dias após a cirurgia. Os implantes de ABS pesaram 0,44g, e os de poliamida 0,61g. A microscopia eletrônica de varredura demonstrou que os implantes de ABS eram formados por microporos equidistantes, enquanto os de poliamida apresentavam microporos de vários tamanhos. A força necessária para fraturar os implantes de ABS foi de 14.39±0.60 Mpa, enquanto para os de poliamida foi de 16.80±1.05Mpa. Quinze dias após a cirurgia, foi observada infiltração fibrovascular centrípeta. Os implantes podem ser utilizados para correção de cavidades anoftálmicas por se mostrarem inertes, biocompatíveis e permitirem a infiltração tecidual.(AU)

ABSTRACT

RESUMO Objetivo: Avaliar a biocompatibilidade da Nanoskin para reposição de volume em cavidades enucleadas ou evisceradas de coelhos. Métodos: Estudo experimental, utilizando implantes de Nanoskin (Innovatecs®, São Carlos, Brasil), celulose bacteriana produzida pela bactéria Acetobacter xylinum tendo como substrato o chá-verde. Implantes de 10mm de diâmetro/5mm de espessura foram colocados em cavidades enucleadas (G1) ou evisceradas (G2) de 21 coelhos, avaliados clinicamente todos os dias, sacrificados aos 7, 30 e 90 dias após a cirurgia. O material foi removido e preparado para exame de microscopia óptica. Resultados: Sinais flogísticos discretos no pósoperatório imediato, não tendo sido evidenciados sinais infecciosos ou extrusão de nenhum implante. Houve aparente redução do volume ao longo do período experimental. Histologicamente ambos os grupos foram muito semelhantes, apresentando aos 7 dias células inflamatórias (predominantemente monócitos e neutrófilos), rede de fibrina e hemácias. A Nanoskin apresentava-se como pequenas esferas, de cor rósea, com pequenos espaços entre elas, permeados por escassas células inflamatórias. As células inflamatórias se modificaram ao longo de período experimental, sendo possível observar aos 30 dias células gigantes multinucleadas e fibroblastos maduros permeando o implante. Aos 90 dias, a estrutura do implante apresentava-se desorganizada, amorfa, com restos necróticos e com áreas ovoides, revestidas por fina membrana rósea, que pareciam se agrupar, vazias ou preenchidas por material acelular, róseo ou acinzentado. Conclusão: A Nanoskin provocou reação inflamatória que levou à reabsorção e redução do volume do implante. Novas formulações devem ser estudadas a fim de ter um produto que seja permanente para reparo da cavidade anoftálmica.


ABSTRACT Objective: The aim of this study was to evaluate the biocompatibility of Nanoskin for replacing volume in enucleated or eviscerated anophthalmic sockets of rabbits. Methods: An experimental study was carried out using enucleated or eviscerated rabbits, which received Nanoskin implants (Innovatecs®, São Carlos, Brazil), a cellulose produced by a bacteria (Acetobacter xylinum) using green tea as substrate. Implants of 10mm diameter/5mm of thickness were used placed in enucleated (G1) or eviscerated (G2) anophthalmic sockets of 21 rabbits.They were clinically examined daily, sacrificed at 7, 30 and 90 days after surgery and the material was removed and prepared for histological examination. Results: There were discrete signs of inflammation in the immediate postoperative period, with no evidence of infection or extrusion in any animal. However apparent reduction of volume during the trial period occurred. Histologically both groups were similar, with inflammatory cells (mainly monocytes and neutrophils), fibrin and hemaceas at 7 days postoperatively.The Nanoskin was presented as small pink spheres, with small gaps between them and permeated by few inflammatory cells. These cells have changed over the study, at 30 days multinucleated giant cells and mature fibroblasts that permeate the implant were observed. At 90 days, the structure of the implant was disorganized, amorphous, with necrotic debris and ovoid areas covered with thin pink membrane that seemed to cluster, empty or filled with no cellular pink or gray material. Conclusion: Nanoskin caused an inflammatory reaction leading to reabsorption and reduction of implant volume. New formulations should be studied in order to have a permanent product to repair the anophthalmic socket.

ABSTRACT

ABSTRACTThis literature review considers the treatment of an anophthalmic socket and the controversial aspects of the implants used to restore the lost volume after enucleation or evisceration, including the different materials employed and the main problems encountered during anophthalmic socket reconstruction. Since the 1980s, when integrated implants were proposed, there has been much controversy about what is the best implant for restoring the lost volume in an anophthalmic socket: integrated or non-integrated implants. Thus, we present this literature review to provide guidance to doctors and consumers.


RESUMOEsta revisão da literatura abrange o tratamento da cavidade anoftálmica, assim como os controversos aspectos relacionados com os implantes de cavidade utilizados para recompor o volume perdido após enucleações ou eviscerações, tais como os diferentes materiais utilizados e os principais problemas enfrentados na reconstrução da cavidade anoftálmica. Depois dos anos 80 do século passado, quando foram introduzidos os implantes integrados, há muitas controvérsias sobre qual seria o melhor implante para recompor o volume perdido na cavidade anoftálmica: implante integrado ou não integrado?

ABSTRACT

PURPOSE: We present clinical results of the use of the multipurpose conical porous synthetic orbital implant (MCOI) in surgical procedures of evisceration, enucleation, and secondary enucleation in ophthalmology patients. METHODS: A retrospective review was performed of 59 eyes in which conical implants were used, including 36 cases of eviscerations, 11 enucleations, and 9 secondary enucleations. In all of the cases, the follow-up period was greater than six months between 2004 and 2013. The results focus on documenting surgical findings, as well as postoperative complications among patients. RESULTS: Superior sulcus deformities were found in six eyes (10.2% of conical implant patients), and two eyes received additional surgical interventions to correct the deformities (3.4%). Blepharoptosis was found in four eyes (6.8%), two of which received upper eyelid blepharoplasty (3.4%). Fornix shortening was reported in only one eye (1.7%). Forty-one eyes had a satisfactory cosmetic appearance after the final prosthetic fitting of conical implants (69.5%). The most frequent postoperative complication was orbital implant exposure, which seemed to occur when the preoperative status of the conjunctiva, Tenon's capsule, and sclera preservation were poor in the eyes of the patients. CONCLUSIONS: There was a lower incidence of blepharoptosis and fornix shortening with the MCOI in comparison to spherical implants, while the incidence of orbital implant exposure was similar with the MCOI in comparison to other types of orbital implants. In addition, the MCOI may have advantages with respect to postoperative cosmetic outcomes.

ABSTRACT

Orbital implants are now routinely used after enucleation and evisceration. However exposure of the implant can lead to infection and extrusion. Hence, early repair of larger exposure with graft material is required. We describe three cases where early postoperative mucosal dehiscence was successfully managed with autologous serum.

ABSTRACT

OBJETIVO: Avaliar experimentalmente a biocompatibilidade de cones de biovidro e biovitrocerâmico em cavidades evisceradas de coelhos. MÉTODOS: Foram utilizados 45 coelhos albinos submetidos à cirurgia de evisceração do olho direito, seguida da inclusão de cones de biovidro e dois tipos de biovitrocerâmicos (chamados de FI e FII) na cavidade escleral. Os animais foram sacrificados em três momentos (7, 90 e 180 dias). Os parâmetros avaliados foram: peso, exame clínico diário, exames bioquímicos, avaliação histológica, exame morfométrico. RESULTADOS: Os animais mantiveram-se saudáveis durante o experimento, não tendo ocorrido extrusão do implante em nenhum animal. O exame morfológico mostrou que houve a formação de pseudocápsula ao redor dos cones, com superioridade dos cones de biovidro e biovitrocerâmico FI, os quais apresentaram menor reação inflamatória e menor formação da pseudocápsula ao redor dos cones que os demais. A reação inflamatória foi mais intensa após 7 dias da colocação dos cones, diminuindo em direção aos 180 dias, sendo menos intensa nos coelhos que receberam cones de biovidro. CONCLUSÃO: Os cones de biovidro e biovitrocerâmico FI e FII podem ser úteis para a reparação da cavidade anoftálmica, com melhor resposta quando se usa cones de biovidro e de biovitrocerâmico FI.


OBJECTIVE: To evaluate bioglass, bioglassceramic biocompatibility in rabbit's eviscerated cavities. METHODS: Forty- five rabbits were submitted to right eye evisceration, followed by the inclusion of bioglass and bioglassceramic I e II prosthesis in the escleral cavity. The animals were sacrificed at seven, 90 and 180 days after surgery. The animals had daily clinical exam; biochemical exam, histological analysis and morphometric evaluation. RESULTS: The animals stayed healthy during the expriment, with good cone integration to the host tissue. None cone extrusion were observed. Histologically, it was observed pseudocapsule formation around the cones and the inflammatory reaction was higher at M1, getting progressively lower while getting at M3, being the lowest in rabbits which received bioglass cones (GA) than at any other groups. CONCLUSION: Bioglass and bioglassceramic I e II cones can be useful to repair anophthalmic cavity.

ABSTRACT

PURPOSE: To investigate the analgesic effect and incidence of postoperative nausea and vomiting (PONV) between the opioid fentanyl and the non-steroidal anti-inflammatory drug ketorolac in patients who underwent eye amputation surgery. METHODS: Retrospective observational case series. Eighty-two patients underwent evisceration or enucleation surgery by one surgeon over a 2-year period. Fentanyl by intravenous patient-controlled analgesia (IV-PCA) at 20 microg/kg with 12 mg/kg ondansetron or intravenous ketorolac at 2 mg/kg/day was administered to patients at postoperative days 0, 1, and 2. The pain score was measured using an 11-point visual analog scale (VAS). The incidence of severe nausea requiring anti-emetics and the incidence of vomiting were reviewed. RESULTS: The mean postoperative VAS in the fentanyl group was significantly lower than that in the ketorolac group on the day of operation for both types of surgery (p = 0.001 and p = 0.004, respectively). At postoperative days 1 and 2, the mean VAS was not different between the two groups for either surgical type (p > 0.05 for both days). The mean VAS was significantly higher in eviscerated patients than in enucleated patients at postoperative days 0 and 1 in the fentanyl group (p = 0.023 and p = 0.016, respectively). However, this was not observed in the ketorolac group. The incidence of PONV was higher in the fentanyl group than in the ketorolac group, although this was not statistically significant for either surgical type (p > 0.05 for both groups). CONCLUSIONS: Fentanyl was more effective as an analgesic than was ketorolac on the day of operation for both surgical types. There was no difference between the two analgesics on postoperative day 1. The analgesic effect of fentanyl in enucleated patients was significantly higher than in eviscerated patients at postoperative days 0 and 1. The use of fentanyl by IV-PCA was associated with greater PONV despite co-administration with anti-emetics, although this finding was not significant.

ABSTRACT

OBJETIVOS: Avaliar as condutas mais utilizadas no tratamento da cavidade anoftálmica no Brasil, comparando-as com a realidade mundial. MÉTODOS: Estudo exploratório, usando questionário eletrônico enviado pela Internet para oftalmologistas membros da Sociedade Brasileira de Cirurgia Plástica Ocular, Vias Lacrimais e Órbita - SBCPO. As respostas obtidas foram avaliadas por meio de análise de aderência, utilizando o teste do Qui-quadrado. RESULTADOS: Foram recebidos 75 questionários respondidos. Cinquenta e três por cento dos entrevistados tratam cavidade anoftálmica frequentemente e o implante de esfera de polimetilmatacrilato, de 18 mm de diâmetro, é o usado pelos entrevistados na maioria das cirurgias, sendo revestido principalmente com esclera (92%). Apenas sete entrevistados já utilizaram implante acoplado com prótese externa. Oitenta e dois por cento dos entrevistados usam a técnica do enxerto dermoadiposo. O acompanhamento destes pacientes é feito semestralmente pela maior parte dos entrevistados. CONCLUSÃO: O tratamento da cavidade anoftálmica no Brasil geralmente é feito usando a esfera de polimetilmetacrilato, de diâmetro 18 milímetros. Implantes acoplados dificilmente são usados.


PURPOSE: To determine the most common approach to repair the anophthalmic socket in Brazil, and to compare the data with the trends in other countries. METHODS: Exploratory study using electronic questionnaire sent by Internet to ophthalmologists members of the Brazilian Orbit and Oculoplastic Society (SBCPO). The received answers were analyzed by adhesion analysis, using Chi-square test. RESULTS: We received 75 answered questionnaires. Fifty-three per cent of the respondents frequently treat anophthalmic socket and use the 18 mm diameter polymethylmethacrylate sphere in the majority of the surgeries, mainly covered by sclera (92%). Only seven interviewees had used integrated implants with pegging procedure. Eighty-two per cent of the ophthalmologists use the dermolipid graft to reconstruct the anophthalmic socket. They also follow the patients bi-annually. CONCLUSIONS: The treatment of anophthalmic socket in Brazil generally involve polymethylmethacrylate sphere with 18 mm diameter. Pegging procedure is uncommon between us.

ABSTRACT

PURPOSE: To evaluate histologically the integration process of cellulose gel produced by Zoogloea sp when implanted into rabbits' eviscerated eyes. METHODS: This experimental study employed 36 eyes of 18 rabbits subjected to evisceration of their right eyes. The sclerocorneal bag was sutured and filled with biopolymer from sugar cane in the gel state. All animals were clinically examined by biomicroscopy until the day of their sacrifice which occurred on the 7th, 30th, 60th, 90th, 120th, or 240th day. The eyeballs obtained, including the left eyes considered controls were sent for histopathological study by optical macroscopy and microscopy. Tissue staining techniques used included hematoxylin-eosin, Masson trichrome (with aniline), Gomori trichrome, Van Gienson, Picrosirius red, and periodic acid-Schiff (PAS). RESULTS: No clinical signs of infection, allergy, toxicity, or extrusion were observed throughout the experiment. The corneas were relatively preserved. Macroscopic examination revealed a decrease of ~ 8% in the volume of the bulbs implanted with the biopolymer. After cutting, the sclerocorneal bag was solid, compact, elastic, and resistant to traction, with a smooth and whitish surface, and showed no signs of necrosis or liquefaction. The episcleral tissues were somewhat hypertrophied. The histological preparations studied in different colors revealed an initial lymphoplasmacytic infiltration, replaced by a fibroblastic response and proliferation of histiocytes, along with formation of giant cells. Few polymorphonuclearneutrophils and eosinophils were also found. Neovascularization and collagen deposition were present in all animals starting from day 30; although on the 240th day of the experiment the chronic inflammatory response, neovascularization and collagen deposition had not yet reached the center of the implant. CONCLUSION: In this model, the cellulose gel produced by Zoogloea sp proved to be biocompatible and integrated into the orbits. Morphometric, immunohistochemical and biodegradability studies should be performed in the future.


OBJETIVOS: Avaliar histologicamente o processo de integração do gel da celulose produzida pela Zoogloe asp implantado em olhos eviscerados de coelhos. MÉTODOS: Estudo experimental utilizando 36 olhos de 18 coelhos. Todos eles tiveram seus olhos direitos eviscerados. A bolsa escleral foi suturada e preenchida com biopolimero da cana de açúcar, no estado gel. Todos os animais foram examinados clinicamente, sob biomicroscopia, até o dia de seus sacrifícios e enucleações que aconteceram no 7º, 30º, 60º,90º,120º e 240º dia. Os bulbos obtidos, inclusive os esquerdos, considerados controles, foram encaminhados para estudo histopatológicos de macroscopia e microscopia óptica. As colorações pela hematoxilina-eosina, tricômio de Masson (com anilina), tricômio de Gomori, Van Gienson e Picrosirius red e ácido periódico de Schiff (PAS) foram usadas. RESULTADOS: Durante o experimento não foram observados sinais clínicos de infecção, alergias, intoxicação ou extrusão. As córneas apresentavam-se relativamente preservadas. Exame macroscópico revelou uma diminuição de aproximadamente 8% no volume dos bulbos nos quais o biopolímero foi implantado. O corte do saco escleral mostrou um conteúdo sólido, compacto, elástico, resistente à tração, com superfície lisa e brancacenta. Não foram observados sinais de necrose, ou liquefação. O tecido epiescleral estava algo hipertrofiado. As preparações histológicas estudadas, nas diversas colorações, revelaram uma infiltração linfomonomorfonuclear inicial, substituída posteriormente por uma resposta fibroblástica e proliferação de histiócitos com formação de células multinucleadas gigantes. Foram também encontrados poucos polimorfonucleares neutrófilos e eosinófilos. A partir do 30º dia houve proliferação vascular e deposição de calágeno em todos os espécimes estudados, embora, no 240º dia do experimento, a resposta inflamatória crônica, a neovascularização e a deposição do colágeno não tinham ainda atingido o centro do implante. CONCLUSÃO: Neste modelo, o gel da celulose produzido pela Zoogloea sp, mostrou-se biocompatível e integrado às órbitas. Estudos morfométrico, imuno-histoquímico e de biodegradabilidade devem ser realizados futuramente.
