“…Nine per cent of participants in the 60 to 64 years age group had vision impairment, compared with 56 per cent in the over 80 years group. More females (30 per cent ) than males (22 per cent ) had vision impairment; in contrast to larger Australian population studies, 6,7 this difference was not significant. The prevalence of near vision impairment was 13 per cent (n = 31), with 10 per cent of participants having a mild impairment (0.34 to 0.59 logMAR; N6 to N12 at 40 cm) and three per cent having moderate impairment or worse (equal to or greater than 0.60 logMAR; greater than N12 at 40 cm).…”

“…The prevalence of VFL in two other population-based samples of Whites 40 years and older from the Netherlands and Australia ranges from approximately 3% to 17% 6,36 with the highest frequencies present in older age groups. The prevalence of VFL in LALES is higher than previously reported in the literature however the methods to determine and categorize individuals as having VFL differed for each of the three studies.…”

Purpose-To examine the association between severity of visual field loss (VFL) and self-reported health-related quality of life (HRQOL) in a population-based sample.Design-Population-based cross-sectional study.Methods-Participants in the Los Angeles Latino Eye Study underwent a comprehensive ophthalmic examination including visual field testing using the Humphrey Automated Field Analyzer II (SITA Standard 24-2). Mean Deviation (MD) scores were used to determine severity of VFL both as a continuous variable and stratified by severity: no VFL (MD≥ − 2 decibels [dB]), mild VFL (6dB

“…In men, visual impairment did not have a significant relationship with age. Blindness and visual impairment has been reported to be higher in women in studies conducted in India, 16 Rotterdam, 6 Melbourne, 17 Oman, 18 and Meiktila. 19 On the other hand, some studies have reported blindness and visual impairment to be higher in men.…”

Purpose To determine the prevalence of visual impairment by age and gender in Shahroud. Methods Using random cluster sampling, 6311 Shahroud inhabitants who were between 40 and 64 years old were invited for ophthalmological examinations. Visual acuity worse than 0.5 LogMAR (20/60) and 1.3 LogMAR (20/ 400) in the better eye was regarded as low vision and blindness, respectively. The cause of blindness was determined by an ophthalmologist and in a person with more than one cause, the most correctable cause was regarded as the main cause. Results This study was conducted on 5190 participants (response rate: 82.2%). On the basis of presenting visual acuity, the prevalence of low vision and blindness was found to be 1.8% (95% confidence interval (CI): 1.4-2.10) and 0.5% (95% CI: 0.3-0.7), respectively. Based on corrected vision, these values were 0.5% (95% CI: 0.3-0.7) and 0.3% (95% CI: 0.1-0.4), respectively. Visual impairment increased with age in women (Po0.001). Uncorrected refractive errors (63.9%), cataract (20.2%), and amblyopia (5.9%) were the most common causes of visual impairment based on presenting vision. Based on corrected vision, however, cataract (42.5%), amblyopia (12.5%), and retinitis pigmentosa (7.5%) were the most common causes of visual impairment. Conclusion Although the prevalence of visual impairment in the city of Shahroud was determined to be lower than two previous studies in the country, correction of refractive errors and cataract could minimize the rate of visual impairment in this population as they were shown to comprise 85% of the causes of visual impairment. The elderly women need to receive more attention.
