ABSTRACT
AIM: To report the demographic characteristics of a sample of population affected by exudative age-related macular degeneration (AMD) in the region of Castilla-Leon (North-Central Spain), and to compare them with a group of population of the same age and from the same geographic area.METHODS: In this observational, prospective study, AMD patients attending a regional reference clinic for photodynamic therapy were interviewed. The patients reported their medical history for high blood pressure, hyperlipemia and smoking habit. Iris color was examined and classified as fight (green, blue and grey) or dark (hazel, brown, black).RESULTS: A total of 343 patients were interviewed. Mean age at onset was 74.9 years (range 55 to 93), Among whom 64.5% were female and 35.5% male. Iris color was rated as light in 45.1% of the patients. Arterial hypertension (AH) was present in 50% of the cases and 15.3% were on treatment for hypercholesterolemia, and 30.2% of the patients were smokers or had quit smoking (80.9% of males).CONCLUSION: The frequency of light colored iris is higher among patients with exudative AMD. In our series, other risk factors for exudative AMD were smoking habit in males, not being on treatment for hypercholesterolemia and being female.
