The effects of indocyanine greend dyne-enhanced photocoagulation on the blood flow in the choriocapillaris and the choroidal neovascularization (CNV)

摘要

Age-related macular degeneration (AMD) is the most common cuase of vision loss in patients aged 65 years and older in the United states. In the majority of cases, the loss of central vision is secondary to exudative changes and fibrovascular scarring following corolidal neovascularization (CNV). Prompt laser treatment is recommmended (Asrani et al., 1996; Macular Photocolagulation study Group, 1993; Schneider et al., 1998). However, direct laser treatment to the entire subfoveral lesion is alomst invariably associated with immediate loss of central vision. Loss of central vision may be ude to direct damage to flveal photoreceptors and retinal pigment epithelium or from damage to the nerve fiber layer serving foveal function (Han et al., 1988).
