Vitrectomy for full-thickness macular hole in adult-onset Coats' disease.

The occurrence of full thickness macular hole in Coats' disease is extremely rare. The purpose of this case report is to report pars plana vitrectomy for the treatment of full thickness macular hole in a patient with adult onset Coats disease. A young male presented with decreased vision in his right eye because of full thickness macular hole. The macular hole was found to be associated with adult onset Coats' disease that was evident on ultra-wide field imaging. The patient underwent laser photocoagulation to the vascular telangiectasia followed by pars plana vitrectomy, large internal limiting membrane peeling and gas tamponade. This resulted in regression of exudation, closure of macular hole and improvement in vision. Coats disease of adult onset can present with decreased vision because of full thickness macular hole. Vitrectomy with internal limiting membrane peeling can result in excellent visual outcome.
