Sammanfattning (abstract):
Aims: To investigate the prevalence of and potential risk factors for ocular disorders and the effects of timing of cataract surgery from age 70–97 years. Population: A representative population sample taken from within the Gerontological and Geriatric Population Studies (H 70) in Gothenburg, Sweden (n = 958). All subjects underwent eye examinations at age 70 years in 1971 and subsequently at ages 82, 88, 95 and 97 years. All inhabitants of Gothenburg aged 95 and 97 years were invited to participate in the study. Results: Decreased vision (visual acuity ≤ 0.5) was found in 20% and 80% of subjects at ages 82 and 97 years, respectively. Blood folate and physical activity at age 70 years correlated positively and body mass index (BMI) negatively to visual acuity (VA) ≥ 0.8 at ages 82 and 88 years. Smoking at age 70 years correlated to early age-related maculopathy (ARM). Cataract surgery had been performed in 40% of subjects at age 97 years. Surgery 2 years earlier led to a 15% increase in time spent with improved vision. Conclusions: The deterioration of vision in elderly people is a major health problem, for which ‘low’ folate status, smoking, ‘high’ BMI and low physical activity are potential risk factors. Early cataract surgery is also beneficial in very old patients.
