Tumors with active leakage require therapy, which can include laser photocoagulation, thermotherapy, indocyanine green-enhanced thermoablation, PDT, cryotherapy, or plaque radiotherapy. Histopathology of acquired vasoproliferative tumor in the early phases when the tumor is mostly vascular has not been clearly established.

It is believed to represent a proliferation of blood vessels, glial tissue, and retinal pigment epithelium, often in response to a previous insult from intermediate uveitis, retinitis pigmentosa, Coats disease, or other conditions.

Later, as the tumor becomes clinically fibrotic, a more reactive astrocytic appearance can be documented. There are a number of vascular tumors of the retina, and each has distinct clinical features, imaging findings, genetic alterations, and management strategies.

It is important to remember that several of these tumors could potentially carry genetic mutations that imply systemic disease and related brain lesions, so genetic testing and MRI can be instrumental in management. We have found an informative website www. As of April , this website had logged 44 tests on disorders with genes from laboratories.
