Özet

Background. An unusual case of Usher syndrome type II associated with bilateral Coats-like exudative retinopathy is described. Methods. A 14-year-old boy with congenital sensorineural deafness and normal vestibular functions presented with a recent history of night blindness. He was followed for 3 years with fundus photography, intravenous fluorescein angiography, electroretinography and audiometric testings. His parents refused any form of treatment. Results. Fundoscopy showed bilateral retinitis pigmentosa and a single focus of subretinal exudation and overlying telangiectatic retinal vessels inferotemporal to the vascular arcade in the right eye. He had bilateral mild macular edema. A year later, a similar lesion developed inferotemporally in the left fundus. Electroretinography responses, particularly the rod-mediated signals, were significantly reduced. Audiometric studies documented hearing loss in high frequencies. His visual acuity declined from 20/40 to 20/80 RE and from 20/80 to 20/100 LE during follow-up. No new lesions developed. Conclusions. Coats-type exudative lesions may develop in patients with Usher syndrome type II. Although left untreated, only a minimal increase in exudation occurred over 3 years.
