Prevalence of Vision Loss in East Asia from 1990 to 2020: Magnitude and Temporal Trends.
Purpose: To determine the magnitude and temporal trends of the prevalence of blindness and vision impairment (VI) in East Asia from 1990 to 2020.
Methods: A systematic review and meta-analysis of population-based studies was performed to estimate the prevalence and affected population of blindness (presenting visual acuity < 3/60 in the better eyes), moderate-to-severe vision impairment (MSVI; 3/60≤ presenting visual acuity < 6/18), mild VI (6/18≤ presenting visual acuity < 6/12) and near VI due to uncorrected presbyopia (presenting near vision
Results: In 2020, East Asia's age-standardized prevalence of blindness, MSVI, mild VI and near VI due to uncorrected presbyopia was 0.47% (95% uncertainty interval [UI], 0.41% to 0.52%), 2.77% (95% UI, 2.49% to 3.07%), 3.41% (95% UI, 3.06% to 3.78%), 7.38% (95% UI, 5.32% to 9.70%), with a higher prevalence in females compared to males. East Asians had lower prevalence of blindness and MSVI than the world population. Despite the decrease (27.7% for males and 27.1% for females) in age-standardized blindness prevalence in East Asia, the number of people with blindness and MSVI has increased from 7.0 to 9.1 million and 30.8 to 53.9 million from 2000 to 2020.
Conclusions: While age-standardized blindness rates have declined in the past two decades, yet the number of people affected by blindness and MSVI continues to rise, indicating unmet eye care demands in East Asia amid population growth and aging.
期刊介绍：
Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
