Fluorescein angiographic findings in the detached and reattached retina

Two cases with retinal detachment were treated with cryoretinopexy, scleral buckling and subretinal fluid-releasing procedures, and examined by pre- and postoperative fluorescein fundus angiography. Capillary dilatation was observed in a wide area of the detached retina. The capillary dilatation was improved in the reattached retina which was not indented by an exoplant, while it was observed in the reattached retina which was indented by an exoplant. After an encircling operation, a background mottling pattern was enhanced in the posterior pole which seemed to be choroidal vascular congestion. These findings suggest that retinal circulation in the detached retina was disturbed, but improved after surgery at least the area which was not indented by an exoplant. Choroidal circulation was disturbed after an encircling operation.
