Subjects: Annual eye examinations were performed during routine physical examinations on Naru Island, Japan from 1995 to 2002. We examined 639 (213 males and 426 females) in1995, 579 (196 males and 383 females) in1998 and 421 (159 males and 262 females) in 2002. Results and Discussion: Pterygium appeared to increase with age. The prevalence of cataract was higher in woman than in man. Cataract was more prevalent in those with pterygium than in those without one. The prevalence of pseudoexfoliation increased with age, and it was greater in those with cataract than in those without one. Conclusions: The incidence of degenerative and agerelated diseases in this population followed for seven years showed a tendency to increase with age., Acta medica Nagasakiensia. 2003, 48(1-2), p.15-21}, pages = {15--21}, title = {Ocular Diseases on Naru Island, Japan: a Seven-year Survey}, volume = {48}, year = {2003} }
