ABSTRACT

ABSTRACT The aim of this study is to present the results of ab-interno trabeculotomy using Kahook Dual Blade in patients with primary congenital glaucoma. An ab-interno trabeculotomy using a dual blade device was performed in three eyes of two patients with the diagnosis of primary congenital glaucoma. One of them in the left eye and the other patient in both eyes. In the first patient, an adequate response was achieved after the intraocular pressure reduced from 36 mmHg to 14 mmHg. The second patient did not respond adequately to the procedure, and high intraocular pressure levels persisted in both eyes after the procedure. The indication of Kahook Dual Blade ab-interno trabeculotomy in primary congenital glaucoma must be cautious and more studies are needed to establish its efficacy and the best indications. Seems that this procedure should not be indicated for primary congenital glaucoma treatment.


RESUMO O objetivo deste estudo é apresentar os resultados da trabeculotomia ab-interno com Kahook Dual Blade em pacientes com glaucoma congênito primário. Foi realizada trabeculotomia ab-interno com dispositivo de lâmina dupla em 3 olhos de 2 pacientes com diagnóstico de glaucoma congênito primário. Um deles no olho esquerdo e o outro paciente nos dois olhos. No primeiro paciente, houve resposta adequada uma vez que a pressão intraocular diminuiu de 36 mmHg para 14mmHg. O segundo paciente não respondeu adequadamente ao procedimento, mantendo altos níveis de pressão intraocular em ambos os olhos após o procedimento. A indicação da trabeculotomia ab-interno com o Kahook Dual Blade no glaucoma congênito primário deve ser cautelosa e são necessários mais estudos para estabelecer a eficácia e as melhores indicações. Parece que esse procedimento não deve ser indicado no tratamento do glaucoma congênito primário.

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

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

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

Objetivo: Caracterizar los pacientes atendidos por glaucoma pediátrico, identificar el tratamiento más utilizado para cada subgrupo y conocer los resultados en referencia al control de la presión intraocular. Método: Estudio retrospectivo mediante revisión de historias clínicas de pacientes con glaucoma pediátrico menores de 15 años, pertenecientes al servicio de oftalmopediatría de la Fundación Oftalmológica de Santander Clínica Carlos Ardilla Lülle, atendidos entre enero/2001 y diciembre/2006. Resultados: Del total de casos recolectados, 46 pacientes tenían glaucoma congénito primario, 15 pacientes con glaucoma del desarrollo y 21 pacientes con glaucoma secundario. La técnica quirúrgica más utilizada fue la trabeculotomía combinada con trabeculectomía (TCO+TCE), seguido por la trabeculectomia aumentada con mitomicina (TCE+MMC) y el tratamiento médico tópico con hipotensores oculares. Conclusiones: El glaucoma congénito primario es la causa más frecuente de glaucoma en niños y la técnica combinada de TCE+TCO es el procedimiento de elección con una tasa de éxito del 69.6%.


Background: Glaucoma infrequently affects infants and children, as compared with adults. The prognosis of any glaucoma is better if it is diagnosed early and brought under control. In our experience, primary congenital glaucoma is the most common paediatric glaucoma, and for this condition, combined trabeculotomy+trabeculectomy is the procedure of choice. Objective: To characterize patients seen with paediatric glaucoma, to identify the most often used treatment for each subgroup and the results in reference to the intraocular pressure control. Method: Retrospective clinical record review of paediatric patients with glaucoma under 15 years old, treated in Oftalmopediatrics Service of the Ophthalmologic Foundation of Santander Carlos Ardila Lülle Clinic attended from January/2001 to December/2006. Results: 46 patients had primary congenital glaucoma, 15 had developmental glaucoma, and 21 had secondary glaucoma. The surgical technique most frequently used was trabeculotomy combined with the trabeculectomy (TCO + TCE), followed by trabeculectomy augmented with mitomycin (MMC + TEC) and medical treatment topic with ocular hypotensive. Conclusions: The primary congenital glaucoma is the most frequent cause of glaucoma in children and the combined technique TEC + TCI is the procedure of choice with success rate of 69.9%.
