Retinal vasoproliferative tumors: surgical management and histological findings.
Vascular masses occurring in the peripheral retina have been described extensively in the literature. Many terms, including "presumed acquired hemangiomas," "hemangioma-like," "angiomatous masses," "angioma-like," "peripheral retinal telangiectasis," and "vasoproliferative tumors," have been suggested that reflect the lack of the known histological features and the potentially variable causes. We describe the histological features of 2 patients who underwent transcleral local resection as management for suspected choroidal melanoma. Pathological examination of these tumors reveals the constituents to be primarily benign glial cell proliferation with secondary vasoproliferation. The weight of the literature agrees with a reactionary process. We therefore suggest the term "reactionary retinal glioangiosis." Transcleral resection has a place where diagnosis is difficult. It prevents an unnecessary enucleation and allows accurate tissue diagnosis.
