  • Abstract
  • Look Inside

We reviewed 122 eyes with age-related macular degeneration showing occult choroidal neovascularization by fluorescein angiography. The 109 patients were aged from 50 to 91 years, average 69 years. The choroidal neovasculariza-tion was classified into three types by indocyanine green angiographic features : focal spots 39 eyes (32%) , plaques 67 eyes (55%) and combined lesions 11 eyes (9%) . The frequency was similar to that by Guyer et al. There was no difference in the natural history and results of photocoagulation among the 3 groups after follow up for 1 year or longer. It appeared that the visual outcome is more influenced by the location and activity of the underlying choroidal neovascularization.
