[Retinal vasoproliferative tumor (retinal reactive astrocytic tumor)]

Area of Science:

• Ophthalmology
• Oncology
• Pathology

Context:

• Retinal vasoproliferative tumors (RVATs), also known as retinal reactive astrocytic tumors, are rare ocular masses.
• These tumors present in the inferior peripheral retina, characterized by vascular abnormalities and exudative manifestations impacting visual prognosis.

Purpose:

• To review the current understanding of retinal vasoproliferative tumors.
• To discuss their classification, associated conditions, differential diagnoses, and therapeutic strategies.

Summary:

• RVATs are predominantly astrocytic and reactive lesions of unknown etiology, classified as primary or secondary.
• Differential diagnosis includes retinal capillary hemangioblastoma in von Hippel-Lindau disease.
• Treatment is essential for visual preservation and involves a combined approach, with conservative methods for small tumors and more invasive options for larger or refractory lesions. Vitreoretinal surgery and anti-VEGF injections are used for complications and associated macular edema.

Impact:

• Establishes the current knowledge base on RVATs, aiding clinicians in diagnosis and management.
• Highlights the importance of a tailored, multimodal treatment approach for optimizing visual outcomes.
• Underscores the need for further research into the etiology and standardized treatment of these rare tumors.
