Premacular fibrosis in juvenile Coats' disease with spontaneous peeling after photocoagulation of the congenital vascular anomalies.

We studied two cases of juvenile coats' disease with visual loss at presentation due to premacular fibrosis. The retinal area with altered vascularization was photocoagulated with the Argon green laser. The membrane retracted in a matter of a few months resulting in improved visual acuity. Afterwards the membrane completely peeled and was seen as a floater attached to the posterior hyaloid. Peeling of premacular fibrosis in juvenile's Coats disease may be observed after photocoagulation treatment. It is suggested that induced posterior vitreal detachment was associated with peeling of the premacular fibrosis.
