  • Abstract
  • Look Inside

Indocyanine green angiography (ICG) in age-related macular degeneration may show hyper-fluorescent areas towards the late phase. These areas lack evidence of classical choroidal neovascularization by fluorescein angiography. The ICG findings suggest the presence of occult choroidal neovascularization or drusen-like substance. We studied 10 eyes with these hyperfluorescent areas by means of microperimetry by scanning laser ophthalmoscope (Rodenstock, Germany). This method allows estimation of focal retinal sensitivity under observation. Relative or absolute scotoma was detected corresponding to the hyperfluores-cent areas in 6 eyes, 60%. The finding shows that retinal sensitivity is impaired in these areas.
