Treatment options in subfoveal choroidal neovascularization secondary to age-related macular degeneration

Laser of the entire area of the neovascular lesion is the only proven treatment for subfoveal choroidal neovascularization secondary to age- related macular degeneration with a poor natural history. However, there are some limiting factors such as patient eligibility, a significant decline in visual acuity after treatment, and a very low possibility of a final vision of 20/100 or better. Although no large benefit of other treatment modalities, such as indocyanine green videoangiography-guided laser photocoagulation, surgical removal of neovascular membranes, and radiation therapy, has yet been proven, carefully selected patients may be suitable candidates for such treatments. This article reviews the status of treatment modalities for subfoveal choroidal neovascularization secondary to age-related macular degeneration, including laser photocoagulation of the entire area of the neovascular lesion, and discusses factors prognostic of visual outcome in these treatment options.
