CLINICAL AND ELECTROPHYSIOLOGICAL EVALUATION AFTER INTRAVITREAL ZIV-AFLIBERCEPT FOR EXUDATIVE AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To evaluate the 6-month safety and efficacy of ziv-aflibercept intravitreal injections for treating exudative age-related macular degeneration. METHODS: Fifteen patients with unilateral exudative age-related macular degeneration were enrolled. The best-corrected visual acuity was measured and spectral domain optical coherence tomography was performed at baseline and monthly. Full-field electroretinography and multifocal electroretinography were obtained at baseline and 4, 13, and 26 weeks after the first injection. All patients received three monthly intravitreal injections of ziv-aflibercept (1.25 mg) followed by as-needed treatment. RESULTS: Between baseline and 26 weeks, the mean logMAR best-corrected visual acuity improved (P = 0.00408) from 0.93 ± 0.4 (20/200) to 0.82 ± 0.5 (20/160) logarithm of the minimum angle of resolution, respectively; the central retinal thickness decreased significantly (P = 0.0007) from 490.3 ± 155.1 microns to 327.9 ± 101.5 microns; the mean total macular volume decreased significantly (P < 0.0001) from 9.51 ± 1.36 mm to 8.08 ± 1.34 mm, and the a-wave implicit time increased, with no differences in the other full-field electroretinography parameters. The average multifocal electroretinography macular responses within the first central 15° showed significantly (P < 0.05) increased P1 amplitudes at 26 weeks. No systemic or ocular complications developed. CONCLUSION: Intravitreal ziv-aflibercept significantly improved the best-corrected visual acuity, multifocal electroretinography amplitudes, central retinal thickness, and total macular volume from baseline to 26 weeks. No retinal toxicity on full-field electroretinography or adverse events occurred during the follow-up period.

Congenital simple hamartoma of the retinal pigment epithelium: a case report.

We report the case of a 56-year-old woman who presented for a routine ophthalmological examination without visual symptoms and had a unilateral black retinal lesion that was detected by clinical examination. Fluorescein angiography and optical coherence tomography findings were compatible with a congenital simple hamartoma of the retinal pigment epithelium. It is very important to detect this tumor and differentiate it from other pigmented fundus lesions that can compromise visual function or result in systemic conditions such as those caused by malignant tumors.

Relato de um caso de paciente feminina de 56 anos que compareceu a uma consulta oftalmológica de rotina sem sintomas visuais e apresentando uma lesão retiniana preta, unilateral, detectada ao exame clínico. As características da angiografia fluoresceínica e da tomografia de coerência óptica foram compatíveis com hamartoma congênito simples do epitélio pigmentado da retina. É muito importante detectar este tumor e diferenciá-lo de outras lesões fundoscópicas pigmentadas que podem comprometer a função visual ou, além disso, afetar o paciente sistemicamente como em tumores malignos.
