Abstract:
Objective To detect the clinical characters and the classification of the congenital retinal vascular anomalies. Methods Nine cases (12 eyes) of congenital retinal vascular anomalies were exa- mined by ocular examination and fundus fluorescein angiography (FFA), in which 3 cases (4 eyes) were examined by indocyanine green angiography (ICGA) simultaneously. Results The congenital retinal vascular anomalies were located at the posterior pole in 8 cases (10 eyes), and extended to peripheral retina in 1 case (2 eyes). Congenital retinal vascular anomalies were classified as follows: congenital retinal macrovessel (1 case, 1 eye); congenital retinal arteriolar tortuosity (2 cases, 3 eyes); inherited retinal venous beading (1 case, 2 eyes); and congenital prepapillary vascular loops (5 cases, 6 eyes). Four cases (5 eyes) were associated with spontaneous hemorrhage induced by physical exertion (Valsalva maneuver). Conclusion Most of the congenital retinal anomalies are located at the posterior pole, involving arteries and veins, and can be associated with spontaneous hemorrhage induced by Valsalva maneuver.
