An Update on Noninfectious Retinal Vasculitis.

Background: Retinal vasculitis (RV) signifies the inflammation of various retinal vessels. Noninfectious RV differs from infectious RV with regard to its pathogenesis and treatment. It can have varied clinical presentations and may be associated with systemic vasculitic diseases. Summary: Noninfectious RV can be caused due to type-III hypersensitivity reactions, increased expression of intracellular adhesion molecules, and genetic susceptibility. Noninfectious RV is primarily classified on the basis of the type of retinal vessels involved. It can be further classified as an occlusive or nonocclusive. RV can be a major association of systemic diseases like Behcet's disease, sarcoidosis and systemic lupus erythematosus. Newer modalities, like ultra-widefield fundus fluorescein angiography, can help in the management of RV. Effective treatment of noninfectious RV requires anti-inflammatory and immunosuppressive therapy. The patients may require treatment with high-dose corticosteroids and biological agents. Anti-vascular endothelial growth factor injections and laser photocoagulation may be indicated to treat the occlusive disease. Prompt treatment may prevent complications like vitreous hemorrhage, neovascular glaucoma, and tractional retinal detachment. The treatment more often requires a multidisciplinary approach. Key Messages: This review provides a comprehensive update on the various causes of noninfectious RV, including both systemic and isolated ocular conditions. It also details various complications and management strategies for this condition. [ABSTRACT FROM AUTHOR]
