ABSTRACT

We present the unusual case of a 35 year-old woman with stage IV melanoma and widespread metastases, who was undergoing treatment with interferon alpha-2b and who presented with interferon-associated retinopathy. The patient, who had been taking interferon treatment for three months, complained of a sudden loss of visual acuity in the left eye. An ocular examination revealed multiple cotton wool spots along the retina and macular involvement. Interferon treatment was suspended. Although rare, retinopathy represents a potentially serious adverse effect of interferon treatment. Although normally patients are asymptomatic, complications derived of its use may arise, which can lead to significant visual impairment. We therefore suggest that before initiating treatment with this drug, patients should be informed of its potential ocular risks, and that regular eye examinations are conducted along with the treatment.


Apresentamos o caso de uma mulher de 35 anos com melanoma em estágio IV e metástases generalizadas tratados com interferon alpha-2b, que proporcionou uma retinopatia associada ao interferon. Mulher de 35 anos de idade tratados com interferon durante os últimos três meses apresentou uma perda súbita da acuidade visual no olho esquerdo. Exame ocular revelou vários pontos de algodão ao longo da retina e mácula. Tratamento com interferon foi parado. Retinopatia associada ao uso de interferon está entre os possíveis efeitos colaterais, embora rara, não deve ser subestimada. Embora geralmente assintomática, complicações decorrentes de seu uso podem levar à perda visual significativa. Consideramos, portanto, que antes de iniciar o tratamento com este medicamento, os pacientes devem ser informados sobre os riscos potenciais e os exames oftalmológicos são recomendados durante cada tratamento.

ABSTRACT

Purpose: To identify the effect of pegylated interferon α-2b and ribavirin treatment in the ocular fundus examination, visual acuity, and visual field. Methods: Prospective observational study was performed at the Hepatology Clinic of São José Regional Hospital and at the Vitreoretinal Department at the Sadalla Amin Ghanem Eye Hospital in patients with chronic hepatitis C before and during treatment with pegylated interferon α-2b together with ribavirin. Results: Six (37.5%) of 16 patients developed retinopathy during the treatment, two of which (12.5%) presented retinal hemorrhage, and four patients (6 eyes) presented cotton-wool spots (25%) that regressed during the treatment. One patient (6.25%) presented transient decrease in visual acuity during the treatment and recovered spontaneously without specific therapy. Conclusion: Recommended treatment methods for hepatitis C may cause transient retinopathy, commonly without any damage to visual function in most patients. Although ocular involvement is rare, follow-up with an ophthalmologist is recommended during the course of the hepatitis C medication. .


Objetivo: Identificar possíveis mudanças no exame de fundo de olho após o início do tratamento, bem como alterações na acuidade visual e campo visual. Métodos: Estudo observacional prospectivo realizado na Clínica de Hepatologia do Hospital Regional de São José e no Departamento de Vítreo e Retina do Hospital de Olhos Sadalla Amin Ghanem, em pacientes com hepatite C crônica antes e durante o tratamento com interferon peguilado α-2b associado à ribavirina. Resultados: Six (37,5%) dos 16 participantes desenvolveram retinopatia durante o tratamento, dois dos quais (12,5%) apresentaram hemorragia retiniana unilateral, e quatro pacientes com exsudatos algodonosos (25%), seis olhos, que regrediu durante o tratamento. Um participante (6,25%) apresentou diminuição transitória da acuidade visual durante o tratamento com recuperação espontaneamente sem tratamento específico. Conclusão: O tratamento recomendado para a hepatite C pode estar associado com o desenvolvimento de retinopatia transitória, geralmente sem dano à função visual na maioria dos pacientes. Embora o envolvimento ocular seja raro, o acompanhamento com o médico oftalmologista é recomendado durante todo o uso da medicação. .
