ABSTRACT

OBJETIVO: Relatar os resultados do uso de mitomicina C (MMC) na cirurgia do glaucoma congênito refratário. MÉTODOS: 44 olhos de 30 pacientes com glaucoma congênito primário refratário, submetidos a trabeculectomia com MMC entre 1993 e 2002 no Serviço de Glaucoma do Hospital São Geraldo, foram estudados retrospectivamente, por meio de análise dos prontuários com seguimento mínimo de seis meses. RESULTADOS: A média de Po reduziu-se de 21,7± 7,2 mmHg no pré-operatório para 12,2±6,8 mmHg no tempo médio de acompanhamento pós-operatório de 42,8 meses (p<0,001). A complicação registrada foi a hipotonia crônica (Po<6 mmHg) em quatro olhos (9,1%), um deles com vazamento de humor aquoso pela bolsa fistulante (teste de Seidel positivo). Não se detectou relação estatisticamente significativa entre a incidência de complicações e o sexo (p=0,14), idade à época da cirurgia (p=0,65), Po pré-operatória (p=0,29), número de colírios no pré-operatório (p=0,39) e número de cirurgias prévias (p=0,94). CONCLUSÃO: O uso de MMC na cirurgia fistulante do glaucoma congênito primário mostrou-se eficaz na redução da Po, porém, a incidência de hipotonia ocular pós-operatória foi alta.

    ABSTRACT: PURPOSE: To report on a new treatment for hyperfiltering bleb as well as its diagnostic criteria. METHODS: Twenty eyes with hypotony due to hyperfiltering bleb caused by trabeculectomy with mitomicin C were treated with bleb resection. The diagnosis of hyperfiltering bleb followed these criteria: intraocular pressure lower than six mmHg (Goldmann tonometer); no inflammation in the anterior segment; presence of an elevated and/or diffuse and avascular bleb with or without microcysts; negative Seidel test; no ciliochoroidal detachment found with ultrasound biomicroscopy. We registered the following data pre and post operatively: type of glaucoma, visual acuity, bleb aspect and fundoscopic findings. A successful resolution of hypotony was achieved when intraocular pressure ranged from six to 14 mmHg with or without antiglaucomatous medication. RESULTS: At a minimum follow-up of 19 months ocular hypotony had been reversed in all eyes. At the last exam, intraocular pressure varied from eight to 14 mmHg in 18 (90%) eyes; 12 (66.7%) eyes had no medication and six (33.3%) used antiglaucomatous medication. In two (10%) eyes, another trabeculectomy was necessary to control intraocular pressure. Hypotonic maculopathy developed preoperatively in seven eyes and was reversed after bleb resection. Visual acuity improved in 15 (75%) eyes but did not change in five (25%). CONCLUSION: Bleb resection is a safe and adequate treatment for ocular hypotony due to hyperfiltering bleb. It also restores vision in a considerable number of patients. The diagnosis of hyperfiltering bleb must follow rigorous criteria.

    ABSTRACT: Objective: This study aims at observing the inhibition of cell proliferation in primary pterygium by the use in vitro of mitomicyn C, cyclophosphamide, methotrexate. Methods: Pterigyum was removed from seven pacients between 30 and 60 years and were submitted to culture of epithelial cells. Later the effect of drugs was tested on the cells: cyclophsphamide, methotrexate, mitomicyn. The cells were observed for five days under the microscope to assess cellular proliferation, and the experiments were repeated five times. Results: When mitomicyn was used, a marked inhibition of cellular proliferation was observed. When cyclophosphamide was used there also was inhibition of cellular proliferation, 50% within 24 hs of the culture exposition to the drug increasing in the following days. Conclusion: The inhibition effects in the cellular proliferation by the use of mitomicyn C was already expected, but the use of cyclophosphamide was also very effective. The cyclophsphamide inhibitory action on fibroblastic proliferation in vitro lead us to believe that it may be used to prevent pterygium recurrence after incision. However, tests in animals and later in humans are necessary.
