Retinal Hemangioblastoma

Retinal hemangioblastoma is a rare, benign vascular tumor that develops from abnormal blood vessels in the retina. It often appears as a reddish-orange, well-defined lesion and can cause complications such as retinal detachment, hemorrhage, or fluid leakage, potentially leading to vision loss if untreated.

​

This tumor can occur sporadically but is commonly associated with Von Hippel-Lindau (VHL) disease, a genetic disorder that causes multiple tumors throughout the body. Diagnosis is made through a detailed eye exam, including fluorescein angiography and imaging, and genetic testing if VHL is suspected.

​

Treatment options depend on tumor size and impact, often involving laser photocoagulation, cryotherapy, or surgical removal to preserve vision and prevent complications. Regular monitoring is essential, especially for patients with VHL, to detect new tumors early and manage them effectively.
