Vitrectomy for epimacular membrane secondary to adult-onset Coats' disease

The authors describe the management of an epimacular membrane secondary to adult-onset Coats' disease. A 26-year-old man presented with decreased vision (20/120) in the right eye for 4 months. Fundus examination revealed features suggestive of Coats' disease, with a thick epimacular membrane. Optical coherence tomography revealed underlying macular thickening. The patient underwent vitrectomy with removal of the epimacular membrane and internal limiting membrane; peripheral telangiectasia were simultaneously photocoagulated. Postoperatively, his visual acuity improved to 20/20, which remained stable for 12 months. Vitrectomy yields an excellent anatomical and functional outcome in epimacular membrane due to adult-onset Coats' disease, if performed before macular exudation leads to subretinal fibrosis.
