Vasoproliferative Tumors of the Retina: Pathophysiology, Clinical Features, and Treatment Approaches.
Most retinal vasoproliferative tumors are secondary to another eye disease
Vasoproliferative Tumors of the Retina: Pathophysiology, Clinical Features, and Treatment Approaches.
Retinal vasoproliferative tumors (retinal vasoproliferative tumors) are rare, benign lesions appearing as elevated, pink masses in the peripheral retina.
KEY MESSAGES: The evolving understanding of retinal vasoproliferative tumors pathogenesis necessitates multicenter studies to establish standardized diagnostic and therapeutic guidelines.
Initially considered acquired retinal capillary hemangioblastomas, retinal vasoproliferative tumors are now recognized as distinct entities, with idiopathic and secondary forms.
Though primarily affecting individuals between 30 and 50 years of age, their pathogenesis remains under investigation.
SUMMARY: Recent histopathological evidence suggests retinal vasoproliferative tumors have a predominantly glial rather than vascular origin.
Management depends on tumor size, location, and complications.
Recent histopathological evidence suggests retinal vasoproliferative tumors have a predominantly glial rather than vascular origin.
Clinically, retinal vasoproliferative tumors cause visual deterioration, floaters, and photopsia, often with subretinal/intraretinal exudation, epiretinal membranes, vitreous hemorrhage, or retinal detachment.
Fluorescein angiography reveals telangiectatic vessels with intense late-phase hyperfluorescence.
Secondary retinal vasoproliferative tumors comprise up to 84% of cases, linked to conditions such as Coats' disease, uveitis, and toxoplasmosis.
