Purpose:
To estimate the age- and gender-specific prevalence of age-related macular degeneration (AMD) in a population-based sample of subjects 60 years of age or older in Thessaloniki, Greece.
Design:
Cross-sectional population-based study.
Methods:
A total of 2554 subjects randomly identified from municipality registers in Thessaloniki underwent a complete ophthalmologic examination.
Results:
Of the 3617 eligible subjects, 2554 (71%) participants completed a clinical examination. The prevalence was 2.5% for AMD, 1.4% for neovascular (NV) AMD, and 1.3% for geographic atrophy (GA). Bilateral AMD was present in 40% of AMD cases. The prevalence of AMD, NV, GA, and bilateral AMD increased with increasing age (P< .0001). No gender-specific statistically significant differences were noted. Of all participants with AMD, 67% were unaware of the diagnosis.
Conclusions:
The prevalence of AMD in Greece is comparable to that in other Caucasian populations. A dramatic increase in prevalence in people older than 80 years of age was observed.
