DETECTION OF SUBRETINAL NEOVASCULAR MEMBR ANES WITH INDOCYANINE GREENVIDEOANGIOGRAPHY

Purpose To evaluate the ability of indocyanine green videoangiography to delineate the subretinal neovascular membranes and to compare with fluoresceine angiography. Methods Between August 1993 and November 199 4, digital fluorescein and indocyanine green videoangiography was perf ormed in 214 eyes of 108 cases. Of the 108 cases, 96 had age-related m acular degeneration 6 had angioid streaks and 3 had degenerative myopi a. Results On fluorescein angiography, 47 of the 214 eyes had well-def ined and 42 had occult subretinal neovascular membrane. Occult membran es were clearly delineated with indocyanine green angiography. Using t hese two angiographies, we could detect subretinal neovascular membran e in 89 eyes. These membranes were in 79 of the 181 eyes with age-rela ted macular degeneration, 5 of the 12 eyes with angioid streaks and 2 of the 6 eyes with degenerative myopia. In addition, 3 eyes of the 3 c ases had idiopathic subretinal neovascular membranes. Conclusion The r esults of this study indicate that lCG videoangiography is an adjuncti ve diagnostic tool to fluorescein angiography in the detection of subr etinal neovascular membranes in age-related macular degeneration and i n other chorioretinal pathologies.
