ObjectiveTo investigate the possible relationship between choroidal neovascularization (CNV) and macular choroidal watershed zones (CWZ) in patients with age-related macular degeneration (AMD).
ObjectiveTo observe and estimate the image characters of indocyanine green angiography (ICGA) and fundus fluorescein angiography (FFA) in atrophic age-related macular degeneration(AMD) and macular drusen.
目的 观察和评价萎缩型老年性黄斑变性 ( age- related macular degeneratioin,AMD)的荧光素眼底血管造影 ( fundus fluorescein angiography,FFA)与吲哚青绿血管造影 ( indocyanine green angiogra-phy,ICGA)图像特征和对比检查的应用价值。
Results The percentage of subsensory retina CNV was significantly higher in the exudative age-related macular degeneration (AMD) cases with course within 2 months than course over 2 months( χ~2=6.687,P=0.010).
Methods Thirty-one eyes of 31 cases of macular diseases, were studied among them there were 15 eyes with idiopathic macular hole (IMH),and the others included 8 eyes with macular epiretinal membranes(ERMs), 4 eyes with age related macular degeneration(AMD) and 4 eyes with idiopathic submacular neovascularizations(SRNV).
Purpose To evaluate short term visual acuity effects of a single photodynamic therapy(PDT) treatment with Visudyne (CIBA Vision Corp, Duluth, Ga) for choroidal neovascularization (CNV) in age related macular degeneration (AMD).
Carotenoids lutein and zeaxanthin are proposed to protect ocular tissues from free-radical damage that can cause cataract and age-related macular degeneration (AMD).
Increasing zeaxanthin in common foods such as potatoes by traditional plant breeding or by genetic engineering could contribute to an increased intake of this carotenoid and, consequently, to a decreased risk of age-related macular degeneration.
In addition to typical skin changes of the pseudoxanthoma elasticum and ocular alterations (exudative macular degeneration and angioid streaks) there were an unusual number of disturbed endocrinological functions.
The ophthalmological findings revealed characteristic breaks in Bruch's membrane, proliferation of chorioidal vessels into the subretinal space, hyperplasia of retinal pigment epithelium and disciform macular degeneration.

Blindness from retinal diseases, including age-related macular degeneration (AMD) and retinitis pigmentosa (RP), usually causes a significant decline in quality of life for affected patients.
