title: Indocyanine green videoangiography of older patients with central serous chorioretinopathy.
abstract: OBJECTIVE
  The authors studied the indocyanine green (ICG) videoangiography findings of central serous chorioretinopathy (CSC) in older adults.
  
  
  BACKGROUND
  Central serous chorioretinopathy in older adults may be confused with the exudative forms of age-related macular degeneration (AMD) because the two entities may have similar ophthalmoscopic and fluorescein angiographic findings. Because of its enhanced ability to image the choroidal circulation, ICG videoangiography has been used to describe certain choroidal vascular abnormalities in young adults with CSC, as well as older patients with choroidal neovascularization (CNV). The ICG videoangiography findings in CSC in older adults is largely unknown.
  
  
  METHODS
  The authors performed ICG videoangiography on 36 patients aged 50 years or older with CSC to characterize their findings.
  
  
  RESULTS
  The ICG videoangiography findings of the patients were consistent, revealing choroidal vascular hyperpermeability manifested by areas of hyperfluorescence that were first seen in the midphase of the angiogram. In the later phases of the angiogram, there were dispersion of the hyperfluorescence and a distinctive silhouetting of the larger choroidal vessels.
  
  
  CONCLUSIONS
  Older patients with CSC have a unique temporal and topographic pattern of hyperpermeability that can help establish the proper diagnosis.
