RESUMO
PURPOSE: To report a patient with Coats' disease who presented with a premacular membrane that was peeled off after laser photocoagulation. CASE SUMMARY: A 17-year-old male presented with decreased visual acuity of the right eye, and showed serous elevation, subretinal hemorrhage, telangiectasis and thick premacular membrane upon fundus examination. Upon diagnosis with Coats' disease, the telangiectatic area was treated with argon laser photocoagulation. Two weeks later, the premacular membrane was peeled off spontaneously and the decrease of macular thickness was verified by optical coherence tomography (OCT). The patient's visual acuity was improved to 1.0. CONCLUSIONS: The visual acuity of the patient with Coats' disease was improved by spontaneous peeling of the premacular membrane after photocoagulation.
