[Ophthalmologic evaluation of patients submitted to drainage implant in refractory glaucoma]. / Avaliação oftalmológica em pacientes submetidos a implante de drenagem em glaucomas refratários.

PURPOSE: To evaluate aspects of patients submitted to drainage implant procedures before and after surgery. METHODS: A retrospective study was done, with patients submitted to drainage implant procedures in the Glaucoma Sector of the Hospital Oftalmológico de Sorocaba, from January, 2004 to December, 2006. The following characteristics were evaluated: gender, age, treated eye, glaucoma type, number of previous ophthalmologic surgeries, previous intraocular pressure and check-ups. The visual acuity was observed before and after the implant, the number of glaucoma medications given after the implant, the main complications and the necessity of a second intervention. RESULTS: Among the 92 patients, 65.3% (n=60) were male and 34.7% (n=32) were female. The main types of glaucoma were 38.9% (n=37) due to cornea transplant and 25.3% (n=24) to neovascular glaucoma. The intraocular pressure average before implant was 32 (+/-11.29) mmHg and after implant it was 18 (+/-8.11) mmHg in 100% (n=95) eyes, 15 (+/- 10.89) mmHg in 100% (n= 95), 16 (+/-11.64) mmHg in 55.7% (n=54) and 20 (+/-10.31) mmHg in 21.6% (n=21) for the period of 2 months, 6 months, 1 and 2 years, respectively. The most frequent complications were implant migration (8.5%) and shallow anterior chamber (5.4%). CONCLUSION: A satisfactory evolution in the patients after implants, taking into consideration several causes of glaucoma. A significant reduction of intraocular pressure was found in the period of 2 months, at 1 and 2 years (p< 0.05). The complications occurred and progressed independent of the type of glaucoma, number of previous surgeries, age or gender.

Avaliação oftalmológica em pacientes submetidos a implante de drenagem em glaucomas refratários / Ophthalmologic evaluation of patients submitted to drainage implant in refractory glaucoma

Objetivo: Avaliar aspectos pré e pós-operatórios em pacientes submetidosa implantes de drenagem. Métodos: Foi realizado estudo retrospectivo, com pacientes submetidos a implante de drenagem no setor de glaucoma do Hospital Oftalmológico de Sorocaba no período de janeiro de 2004 a dezembro de 2006. No estudo foram avaliadas as seguintes características: sexo, idade, olho operado, tipo de glaucoma, número de cirurgias oculares anteriores, pressão intraocular prévia e após, conforme tempo de seguimento. Foram observadas a acuidade visual pré e pós-implante, o número de medicações antiglaucomatosas prescritas pós-implante, as principais complicações e reintervenções necessárias. Resultados:Entre os 92 pacientes a proporção foi de 60 (65,3%) do sexo masculino e 32 (34,7%) do feminino. Os principais tipos de glaucoma foram: 38,9% (n=37) secundário a transplante de córnea e 25,3% (n=24) glaucoma neovascular. A média da pressão intraocular pré-implante foi de 32 (±11,29) mmHg e pós-implante foi de 18, (±8,16) mmHg em 95 (100%) pacientes, 15,00 (±11,00) mmHg em 95 (100%), 16 (±11,64) mmHg em 54(55,7%) e 20 (±10,14) mmHg em 21 (21,6%) para o período de 2 meses,6 meses, 1 ano e 2 anos, respectivamente. As complicações mais frequentes foram extrusão do implante (8,5%) e atalamia (5,4%). Conclusão:Observou-se evolução satisfatória nos pós-implantes, independente das diversas causas do glaucoma. Neste estudo foi encontrada redução significante da pressão intraocular 2 meses, 1 ano e 2 anos (p<0,05). Ascomplicações tiveram ocorrência e evolução independente do tipo de glaucoma, número de cirurgias prévias, idade e sexo.
