confidence interval [CI], 2.6-7.0) were found to have intermediate soft drusen measuring 63 to 125 µm in either eye; 1.2% (95% CI, 0.0-2.3) had large soft distinct drusen larger than 125 µm; and 0.6% (95% CI, 0.0-1.4) hadlargesoft,crystalline,orsemisoliddrusen.Thesame figures for those 80 years and older were 18.2%(95%CI, 9.8-26.6),10.9%(95%CI,4.0-17.8),and25.5%(95%CI, 18.4-32.6), respectively. Geographic atrophy was found in either eye in 9.2% of those participants 70 years and older (95% CI, 5.6-12.7), and exudative macular degeneration was found in 2.3% of participants 70 years and older (95% CI, 0.5-4.1). Conclusion: Geographic atrophy was found to be more common in our study than in other population-based studies.
