ObjectiveTo evaluate the surgical effects for Coats′ disease.MethodsA total of 16 patients (17 eyes) with Coats′ disease accompanied by exudative retinal detachment underwent cryocoagulation therapy and vitrectomy. The post-operative follow-up lasted 4.25-62.25 months (mean 13.10 months). ResultsAfter the operation, retina reattached completely in 8 eyes (without silicon oil tamponade) with the reattachment rate of 47%, reattached with silicone tamponade in 1 eye, and didn′t completely reattached in 8 eyes. The post-operative vision improved in 5 eyes, remained still in 2 eyes，and decreased in 7 eyes. The operative complications included transitory exacerbation of exudative retinal detachment, focal preretinal proliferation, cataract, secondary glaucoma and vitreous hemorrhage.ConclusionMost of the patients with Coats′ disease accompanied by exudative retinal detachment may have reattached retina after the surgery, and some patients have improved visual acuity.(Chin J Ocul Fundus Dis, 2005,21:145-147)
