Abstract Details

Purpose:

To evaluate the prevalence of early and late age-related macular degeneration (AMD) in two Portuguese population-based samples.

Setting:

Department of Ophthalmology, Centro Hospitalar e Universitário de Coimbra, Coimbra, Portugal. Association for Innovation and Biomedical Research on Light and Image, Coimbra, Portugal.

Methods:

Cross-sectional population-based study. Patients older than 55 years old of two Portuguese primary health-care units were invited to participate: one from a coastal village of the center of Portugal and another from the inner region of the country. Responders underwent complete ophthalmologic examination and fundus imaging. Early and late age-related macular degeneration were defined according to the International Age Related Macular Epidemiological Study Group Classification. An innovative semi-automated software (RetmarkerAMD Research, Critical Health, SA, Portugal) was used for grading. The age and gender adjusted prevalences of early and late AMD were determined.

Results:

Of the 8430 eligible subjects, 6025 underwent study procedures (71.5% response rate) and 5998 were included in the analysis, with a mean age of 68.68 ± 8.7 years. The overall prevalence of early AMD was 18.88%. Late AMD was present in 1.11% of the study population, with neovascular and geographic atrophic subtypes accounting for 0.47% and 0.65% of individuals, respectively. The highest prevalence of advanced AMD was among those aged ≥75 years. Over 80% of the study population showed no features of age-related maculopathy or only drusen <63 µm.

Conclusions:

To our knowledge, this was the first AMD epidemiologic study performed in a Portuguese population. The early forms of the disease presented similar prevalence of other large-scale population-based cohorts, but late AMD, namely the neovascular form, was less frequent than previously reported.
