“…Early life visual impairment, particularly in the 0-9-year age bracket, is predominantly due to uncorrected refractive errors, signifying an urgent need for enhanced pediatric eye care that includes regular screenings and access to corrective lenses (13)(14)(15). For those aged 15 to 50 years, the onset of conditions such as glaucoma and age-related macular degeneration (AMD) marks a shift to more complex and sometimes irreversible causes of impairment, thus requiring early and sophisticated medical intervention (16)(17)(18).…”

Objective: Vision impairment and eye diseases significantly affect quality of life and present a substantial public health challenge. According to the TUIK and the World Health Organization, a significant portion of the population suffers from preventable or unaddressed visual impairments. Understanding the prevalence, causes, and demographic distribution of these impairments can aid in formulating effective public health strategies. To analyze the prevalence, determinants, and demographic characteristics of individuals with vision impairment in Turkey, using data provided by TUIK. This proposal aims to utilize existing data to provide valuable insights into the public health issue of vision impairment in Turkey and to foster improved outcomes through targeted intervention strategies. Methods: Secure access to TUIK health survey data focusing on vision impairment in the population aged 0–65 years. We collected additional variables that may influence vision health, such as socioeconomic status, access to healthcare, educational level, and urban versus rural residence. We conducted a cross-sectional study using TUIK data from 2019 onwards, including demographic variables (age, sex, education, and income), and correlated them with the incidence and type of vision impairment. Results: Visual impairment affects approximately 1039000 individuals in Turkey, with a prevalence rate of 1.4%. There was a pronounced increase in visual impairment with age, peaking at 46.5% in those aged > 75 years. Females exhibited higher rates of impairment in most age groups. The most common causes of visual impairment include uncorrected refractive errors in children and young adults, glaucoma in adults aged 15-50, and age-related macular degeneration and diabetic retinopathy in those aged > 50 years. Conclusion: This study highlights a significant age and sex disparity in the prevalence of visual impairment in Turkey, necessitating age-specific and gender-responsive public health strategies. Prioritizing early screening, access to corrective measures, and managing age-related ocular diseases can address the increasing burden of visual impairment. Interventions should be tailored to mitigate risks and provide equitable healthcare access to improve visual health outcomes in the Turkish population.

“…Previous studies have identified that advanced age, female sex, low socioeconomic status, low education level, memory decline, depression, temporary housing, obesity, and having chronic diseases, such as hypertension or diabetes, as risk factors are associated with visual impairment ( 10 – 12 ). Most such studies were conducted on relatively small regional populations ( 13 , 14 ), yet the prevalence of visual impairment varies markedly between populations ( 13 , 15 – 17 ). The epidemiological and geographical variations of visual impairment among the older population in China remain unclear.…”

ObjectiveThis study aimed to estimate the prevalence of visual impairment and to identify the factors associated with it in China.MethodsData for this cross-sectional study were retrieved from the China Health and Retirement Longitudinal Study (CHARLS) for a total of 16,480 subjects who completed the questionnaire between June 2011 and March 2012. The prevalence of visual impairment was estimated considering the complex survey design and response rate. Associated factors were identified using the weighted logistic regression analysis.ResultsThe overall prevalence of visual impairment among middle-aged and older Chinese adults was 6.22%. Regionally, Qinghai and Gansu provinces showed the highest prevalence of visual impairment, whereas Shanghai showed the lowest prevalence of visual impairment in China. Older age (OR = 1.888; 95% CI: 1.537–2.467) was correlated with a higher likelihood of visual impairment, whereas a non-alcohol intake (OR = 0.072; 95% CI: 0.018–0.246) was correlated with a lower likelihood of visual impairment. Hypertension (OR = 1.299; 95% CI: 1.189–1.467), diabetes (OR = 2.000; 95% CI: 1.163–3.765), lung diseases (OR = 1.795; 95% CI: 1.067–3.019), liver diseases (OR = 1.270; 95% CI: 1.221–2.876), stroke (OR = 1.135; 95% CI: 1.107–3.528), and heart disease (OR = 1.350; 95% CI: 1.104–1.708) were significantly associated with visual impairment.ConclusionGeographical variations in the prevalence of visual impairment in China were defined, indicating that such variations do exist in China. Age, alcohol intake, hypertension, diabetes, lung diseases, liver diseases, stroke, and heart disease were factors associated with visual impairment.
