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.
