ABSTRACT

PURPOSE: To evaluate the diagnostic ability of the ibopamine provocative test for early glaucoma detection. METHOD: A sample of 44 patients with suspicious optic discs was recruited and compared with 37 controls with normal optic discs and no ocular pathology. The ibopamine test was performed in all patients who were then followed up with diagnostic tests for glaucoma, visual fields, and spectral-domain optical coherence tomography. RESULTS: Early glaucoma was diagnosed in 26 patients. The sensitivity of the ibopamine test to discriminate patients who had early glaucoma was 78.7%, with a specificity of 71.6%. In multivariable analyses adjusted for demographic and clinical variables, participants with a positive ibopamine test at baseline had an 8-fold higher risk of glaucoma compared with those who had a negative test; glaucoma risk was highest among ibopamine-positive subjects with initial clinical diagnostic impression of glaucoma. CONCLUSIONS: The ibopamine test showed an adequate diagnostic performance to detect individuals at increased risk of glaucoma in a very early stage of the disease. While further studies are required, the provocative ibopamine test for the diagnosis of early glaucoma is promissory.

ABSTRACT

El glaucoma congénito primario es una enfermedad de tratamiento esencialmente quirúrgico. La trabeculectomía con mitomicina-C ha sido utilizada tanto como primera elección o como segunda cirugía cuando ha fallado algún otro procedimiento quirúrgico. En esta revisión se analizaron de manera retrospectiva los casos presentados en nuestro hospital en los últimos 10 años y se compararon con los casos en donde se realizó trabeculectomía simple o esclerectomía, valorando la agudeza visual, la presión intraocular, el diámetro corneal y la excavación papilar tanto pre como postquirúrgica, así como la formación de la vesícula filtrante. Se encontró mayor éxito en la trabeculectomía con mitomicina-C comparada con las otras 2 técnicas, además de que las complicaciones no fueron mucho mayores a lo reportado en la literatura. Concluimos que la técnica de trabeculectomía con mitomicina-C puede ser segura pero sugerimos un estudio prospectivo para poder tener suficiente poder estadístico, mejorar la calidad de las mediciones y controlar las variables adecuadamente.
