Purpose: Idiopathic polypoidal choroidal vasculopathy (IPCV) is a rare exsudative maculopathy in Europe, which similar to age-related macular degeneration (AMD) is accociated with serous and hemorrhagic pigmentepithelial and neurosensory detachments. To determine the frequency of IPCV in a series of patients suspected of having choroidal neovascularization (CNV) secondary to macular degeneration.
Methods: The fluorescein and indocyanine grenn (ICG) angiograms of 1753 consecutive patients with presumed neovascularized macular degeneration werde reviewed. Diagnosis of IPCV was made when ICG angiography showed hyperfluorescent saccular dilatations in the choroidal vasculature in the early phase and wash-out of these lesions in the late phase.
Results: IPCV was diagnosed in 14 patients. All patients were white and older than 50 years of age. Peripapillary lesions were seen in 6 and macular lesions in 8 patients, 10 lesions were unilateral and 4 bilateral. Soft drusen in the fellow eye were seen in 2 of the 14 patients.
Conclusion: Some patients suspected of having CNV secondary to AMD will instead have IPCV to account for their exsudative macular degeneration. It is important to differentiate IPCV from neovascular AMD since there are significant differences in the natural course, visual prognosis and management of these patients.
