Indocyanine green angiography (ICGA) in pathological myopia

One hundred and fifty patients (300 eyes), mean age 49 +/- 15 years, with degenerative myopia underwent fluorescein and indocyanine green angiography (ICGA). Fluorescence of choroidal neovascularization (CNV) on ICGA was less evident than with fluorescein angiography (FA). FA revealed CNV in 98 eyes; ICGA showed CNV with different angiographic patterns in 82 eyes. ICGA permitted CNV diagnosis when retinal hemorrhages were present. ICGA allowed a more precise evaluation of lacquer cracks which appeared more numerous than the ones identified by FA. ICGA visualized the retrobulbar vasculature. This study shows that ICGA has a useful role for diagnosing and managing pathological myopia.
