Polypoidal choroidal vasculopathy and exudative age-related macular degeneration in Greek population.
OBJECTIVE
To study the prevalence, the clinical features, and the visual prognosis without treatment of polypoidal choroidal vasculopathy (PCV) in a large series of Greek patients presenting with exudative maculopathy.


METHODS
The medical records, photographs,as well as fluorescein and indocyanine green(ICG) angiograms of a series of 268 consecutive elderly white Greek patients, who were originally diagnosed as having exudative age-related macular degeneration (AMD) were reviewed retrospectively.


RESULTS
In all, 22 of the 268 (8.2%) patients initially suspected of having AMD were ultimately diagnosed with PCV. In 15 of the 22(68.2%) patients with PCV, the polypoidal lesions were located in the peripapillary area. Large soft drusen were present in only two fellow eyes of the 10 (20%) patients with unilateral PCV compared with 120 fellow eyes of the 148 (81.1%) patients with unilateral AMD. At the last examination, 11 of the 22(50%) patients with PCV and 120 of the 246(48.8%) patients with AMD presented a visual acuity of less than 6/60 in at least one eye due to scar formation in the macula.


CONCLUSIONS
PCV is not an infrequent disease in Greece. A measurable number of Greek patients with findings suggestive of exudative AMD will instead have PCV. ICG angiography is important in differentiating between these two clinical entities. In Greeks, polypoidal lesions are predominantly peripapillary and are not usually associated with macular drusen in the fellow eye. PCV and exudative AMD do not differ significantly in terms of their natural course and visual prognosis in Greek patients.
