Prevalence of Eye Disorders in Elderly Population of Tehran, Iran
Introduction: The decline of visual function with increasing age is a significant concern in elderly. Despite previous work on prevalence of specific ophthalmic pathologies, there has not been enough valid data about overall eye disorders in Tehran yet, and it is poorly defined and not underpinned by strong evidence. The purpose of this study was to investigate the common eye disorders in the elderly population of Tehran.
Methods: A total of 392 elderly community residents aged 60 to 96 were enrolled. The 278 older adults referred to Tehran’s Polyclinic of 6th Region of municipality and 114 older adults referred to the health centers of 9th Region of municipality between 2013 and 2014 were examined. All participants underwent an extensive ophthalmologic screening examination including cataract, diabetic retinopathy of optic nerve, macular degeneration, and glaucoma. The prevalence of various eye disorders was calculated as percentages of the total study population and categorized by age and sex.
Results: Of the 392 participants, 152 subjects (38.8%) had no eye disease. Common visual impairments in elderly were cataract (39.3%), macular degeneration (11.5%), diabetic retinopathy of optic nerve (5.6%) and glaucoma (4.8%). It has also showed cataract prevalence increased with age from (6.3%) in the 60-64 age group to (47.6%) for the patients 85years of age and older.
Conclusion: Cataract is the most frequent eye disease in community dwelling older adults that should be considered at a younger age by health officials to provide preventive programs. Improving accessibility to surgery for the treatment of cataract among the old people will help diminish of untreated cataract that lead to visual impairment.
