Abstract OBJECTIVE: To describe the clinical features of vasoproliferative tumors of the ocular fundus and to propose a comprehensive classification of these tumors. METHODS: A retrospective review of all cases that were diagnosed as acquired retinal hemangioma or vasoproliferative retinal tumor was conducted on the Ocular Oncology Service at Wills Eye Hospital, Philadelphia, Pa. RESULTS: There were 129 vasoproliferative tumors in 113 eyes of 103 patients. The tumors were classified as idiopathic in 84 eyes (74\%) and secondary to preexisting ocular disease in 29 (26\%). Subclassification into solitary (88 eyes), multiple (17 eyes), and diffuse (eight eyes) involvement was made. Of the 84 eyes with idiopathic tumors, 73 (87\%) had solitary tumors, five (6\%) had multiple tumors, and six (7\%) had diffuse tumors. The lesion was located in the inferior, inferotemporal, or temporal region of the fundus in 78\% and developed within 6 mm of the ora serrata retinae in 88\%. Associated vitreoretinal findings included intraretinal exudation (82\%), secondary exudative retinal detachment (48\%), vitreous cells (46\%), vitreous hemorrhage (21\%), preretinal macular fibrosis (31\%), and macular edema (18\%). Of the 29 eyes with secondary tumors, the tumor was solitary in 15 (52\%), multiple in 12 (41\%), and diffuse in two (7\%). The most common preexisting ocular disease included intermediate uveitis (pars planitis) in eight eyes (28\%), retinitis pigmentosa in six (21\%), toxoplasmic retinitis in two (7\%), toxocariasis in two (7\%), retinochoroidal coloboma in two (7\%), and traumatic chorioretinopathy in two (7\%). Retinal pigment epithelial hyperplasia was a prominent feature that was adjacent to 58\% of the secondary tumors. Overall, management of the 129 tumors consisted of observation in 63 (49\%), cryotherapy in 54 (42\%), laser photocoagulation in seven (5\%), plaque radiotherapy in three (2\%), and other modes of treatment in two (2\%). CONCLUSIONS: Vasoproliferative retinal tumors can be idiopathic, or they can develop secondary to congenital, inflammatory, vascular, traumatic, dystrophic, and degenerative ocular diseases. They can produce a variety of complications. Awareness and recognition of these tumors and differentiation from other retinal vascular tumors are important.
