Abstract
The authors examined 100 consecutive cases of exudative age-related macular degeneration (ARMD) from their own practice in a retrospective study to evaluate the ability of fluorangiography (FAG) and indocyanine green angiography (ICGA), performed with a scanning laser ophthalmoscope (SLO) to detect choroidal neovessels (CNVs). Sixteen percent of CNVs were imaged by FAG, 36% by ICGA, 2% of cases had a purely serous pigment epithelium detachment and 46% had occult CNVs. ICGA imaged 42.9% of occult CNVs after FAG. 27% of choroidal membranes were eligible for laser photocoagulation with central vision sparing: 13% detected by FAG and 14% by ICGA (extrafoveal or delineated feeder vessel). Among occult CNVs after FAG, ICGA detected 16.7% of cases eligible for laser photocoagulation. On the bases of FAG results, patients suffering from exudative ARMD can be eligible for laser photocoagulation only in a few cases. In our experience ICGA can enhance this number of over 100%. Nevertheless only 27% of our cases could be treated with foveal sparing. An early diagnosis and following fluorescein and indocyanine green angiography is important to stop evolution of CNV.
