A case of Coats' disease with a peeling of premacular fibrosis after photocoagulation

We report a 26-year-old man with Coats' disease associated with premacular fibrosis. As an initial treatment, the peripheral exduative area was treated with argon laser photocoagulation. Six weeks later, the premacular fibrosis was peeled off and the posterior vitreous membrane was also detached. The patient's visual acuity improved to 20/20. We also observed a change of the vitreous component before and after the treatment that was similar to posterior vitreous detachment (PVD). This is the first reported case in which a distinct vitreous change was observed after premacular fibrosis peeling in Coat's disease.
