ABSTRACT
ABSTRACT A 33-year-old male presented to our clinic with low vision in both eyes that started during the previous week. Visual acuity was 20/63 in the right eye and 20/50 in the left eye. Fundus examination revealed signs of hypertensive retinopathy; thus, a multidisciplinary approach was adopted for the diagnosis and treatment of this patient. We consulted the nephrology and cardiology departments on this case. Upon diagnosing malignant hypertension and renal failure, the patient was put on hemodialysis. His visual acuity was 20/20 at 6 months, whereas foveal assessment on optical coherence tomography angiography revealed neither marked superficial and deep capillary density loss and foveal avascular zone enlargement nor a decrease in disc flow and radial peripapillary capillary density. Early diagnosis and treatment of malignant hypertension are critical in preventing progression of end-organ damage including the eyes. Optical coherence tomography angiography may be useful in cases when fundus fluorescein angiography is relatively contraindicated (e.g., renal failure).
RESUMO
RESUMO Um homem de 33 anos apresentou-se à nossa clínica com baixa visão em ambos os olhos que começou uma semana antes. A acuidade visual foi de 20/63 no olho direito e 20/50 no olho esquerdo. O exame de fundo de olho revelou sinais de retinopatia hipertensiva; então, adotou-se uma abordagem multidisciplinar para o diagnóstico e tratamento desse paciente. Consultamos os departamentos de nefrologia e cardiologia neste caso. Ao diagnosticar hipertensão maligna e insuficiência renal, o paciente foi colocado em hemodiálise. Sua acuidade visual era 20/20 aos 6 meses, enquanto a avaliação foveal com angiotomografia de coerência óptica não revelou perda de densidade capilar superficial e profunda acentuada e aumento da zona avascular foveal nem uma diminuição no fluxo de disco e na densidade capilar peripapilar radial. O diagnóstico precoce e o tratamento da hipertensão maligna são fundamentais na preveção da progressão de danos nos órgãos-alvo, incluindo os olhos. A Angiografia por tomografia de coerência óptica pode ser útil nos casos em que a angiografia com fluoresceína do fundo de olho é relativamente contraindicada (por exemplo, insuficiência renal).
