Indocyanine green videoangiography in macular variant of idiopathic polypoidal choroidal vasculopathy.
BACKGROUND
Fifty patients diagnosed with choroidal neovascularization in age-related macular degeneration were examined by indocyanine green videoangiography. Results were correlated with fundus photographs and fluorescein angiograms. Two patients were diagnosed with the macular variant of idiopathic polypoidal choroidal vasculopathy.


METHODS
Two middle-aged hypertensive women were diagnosed with macular idiopathic polypoidal choroidal vasculopathy. Throughout the follow-up period, both cases showed improved signs and symptoms without worsening of visual acuity, and despite the absence of definitive therapy.


METHODS
Indocyanine green videoangiography demonstrated the characteristic polypoidal lesions in idiopathic polypoidal choroidal vasculopathy better than fluorescein angiography, particularly when blood, exudates, or pigment epithelial detachments blocked visualization of the lesions.


CONCLUSIONS
Incidence of idiopathic polypoidal choroidal vasculopathy may not be as low as reported, as its presentation mimics choroidal neovascularization in age-related macular degeneration. Differentiation can be made only through indocyanine green videoangiography. Conservative management may be beneficial, as visual prognosis is good.
