title: Detection of choroidal aneurysms with indocyanine green videoangiography.
abstract: BACKGROUND
  Aneurysms of the choroidal vasculature have been described only in histopathological studies.
  
  
  METHODS
  Indocyanine green videoangiograms obtained with the scanning laser ophthalmoscope from 32 patients with geographic atrophy were reviewed.
  
  
  RESULTS
  In 8 of 32 patients indocyanine green videoangiography (ICGVA) showed hyperfluorescent aneurysms along choroidal arteries. The same aneurysmal formations were found in two of the eight patients on very early images of fluorescein videoangiography before dye leakage occurred. Seven of eight patients with choroidal aneurysms had a history of hypertension.
  
  
  CONCLUSIONS
  ICGVA is a useful diagnostic tool in detecting choroidal aneurysms. Multiple mechanisms are probably involved in the pathogenesis of choroidal aneurysms, among them the higher hemodynamic stress in the macular region, hypertension and aging.
