COATS DESEASE IN A 7-YEAR-OLD BOY CASE REPORT

Introduction

Disease Coats(CD) is an idiopathic condition in retina that,classically, affects more men. Symptoms are painless with low visual acuity(LAV), leukocoria or asymptomatic. Normal to eye examination previous while in retinal assessment there telangiectasias , exudation intraretinal, serous retinal detachment, and hemorrhage retinal. Although suggestive fundscopy,the diagnosis is done with the aid of OCT,angiofluoresceinography(FA) and ultrasound (USG), the latter being fundamental at the main differential diagnosis: retinoblastoma.

Methods

7-years-old-boy, referred by other service due to “eye damage” in the left eye(OS). Parents, healthy, deny any complaint. On ophthalmologic exam, best correct visual acuity was 20/15 / 20/600; pupils were normal. At the slit-lamp, no changes. OS fundoscopy revealed disc within normal range, exudative lesion with atrophic foveal center, hard exudates in the middle periphery, peripheral telangiectasias, inferior serous retinal detachment. First of all, the differential diagnosis of retinoblastoma was ruled out by B-mode that revealed serous retinal detachment at the posterior pole. OCT findings absence of foveal depression, disorganization of the layers of the internal retina and intraretinal fluid, disruption of the photoreceptor layer and RPE and subfoveal hyporeflective image.The FA showed preserved scleral ring hyperfluorescence, telangiectatic vessels,peripheral vascular deformation,hypofluorescence by vascular exclusion and hyperfluorescences by leakage and macular pooling. He was referred for cryotherapy. Right eye exams within the normal range

Results

Medical record review.

Discussion

The difficulty early diagnosis happens because CD affects children, is unilateral and, in most cases,only with LAV as symptomatology. An effective treatment can improve a better prognosis, which is individual and variable. Treatment depends on the stage of the disease and it varies between monitoring, photocoagulation, cryotherapy, vitrectomy anti - VEGF1 up until enucleation.
