Antivascular endothelial growth factor in hereditary dystrophies.

Choroidal neovascularization can rarely complicate the course of a number of chorioretinal hereditary dystrophies leading to an even further impaired vision function. In recent years, several case reports and case series have shown that intravitreal injections of antivascular endothelial growth factor drugs can be effective in treating subfoveal choroidal neovascularization secondary to chorioretinal dystrophies either improving vision, or at least halting its progressive loss. Additional studies are warranted to confirm the initial positive response and to assess the best therapeutic regimen.
