“…Different methods and population studied may be responsible for the difference in association between refractive error and gender. 485(89.3%) individuals had low hypermetropia, similar results were reported by Alemu et al 31 (low hyperopia 86% as compared to high hyperopia 4.5%) and Raju et al 9 In our study, 176(73.3%) of individuals out of 240 were having low astigmatism. Similar results were reported by Raju et al 9 (low astigmatism 54.78%) and Abdullah et al which showed that low astigmatism was the most prevalent astigmatic error.…”

BACKGROUND Refractive error is an optical defect, intrinsic to the eye which prevents light from being brought to a single point focus on the retina, thus reducing normal vision. Diagnosis and treatment of refractive error is relatively simple and is one of easiest ways to reduce impaired vision. We wanted to determine the prevalence and frequency of various types of refractive errors in rural population of Ganjam, Odisha. METHODS This is a cross sectional study in which 7,384 individuals in the age group of 5-60 years were evaluated during teleophthalmology visits during the period October 2016 to September 2018, in the rural population of Ganjam, Odisha. Individuals whose VA was <6/6 were further evaluated using slit lamp, retinoscopy and ophthalmoscopy. The requisite refractive error correction was carried out and the results were properly recorded to diagnose the type of refractive error. RESULTS The Prevalence of refractive error was found to be 27.40%. Refractive error was found to be more common in males (30.38%) as compared to the female rural population which reported a prevalence of 23.65%. The prevalence of refractive errors was found to be highest in the age group of 5-10 years i.e., 35.50%. In our study, myopia was the most common type of refractive error accounting for 61.31% followed by hypermetropia 26.82% and astigmatism 11.85% respectively. Myopia was the most common refractive error in both males (60.38%) and females (62.82%). Hypermetropia was found to be more common in females (30.69%) as compared to males (24.4%). Astigmatism was more common in males (15.17%) as compared to females (6.47%). It was observed that myopia was the most common refractive error in the age group 5-10 years (75.4%), while hypermetropia was most commonly observed in the age group 41-50 years (41.3%). Out of the 2,024 rural population having refractive error (21.09%), individuals were using glasses. Rest were either unaware or not using glasses. 14.7% of rural population with refractive error had history of spectacle use in siblings and 9.7% had history of spectacle use in either parents. CONCLUSIONS Rural population represents a high-risk group and is often neglected while it accounts for significant proportion of refractive errors. Most of the rural population are unaware of their refractive errors. Refractive errors can be easily treated with spectacles and as such, the detrimental impact of visual impairment on the quality of life can be easily prevented.

PurposeThe aim of the study was a systematic review of refractive errors across the world according to the WHO regions.MethodsTo extract articles on the prevalence of refractive errors for this meta-analysis, international databases were searched from 1990 to 2016. The results of the retrieved studies were merged using a random effect model and reported as estimated pool prevalence (EPP) with 95% confidence interval (CI).ResultsIn children, the EPP of myopia, hyperopia, and astigmatism was 11.7% (95% CI: 10.5–13.0), 4.6% (95% CI: 3.9–5.2), and 14.9% (95% CI: 12.7–17.1), respectively. The EPP of myopia ranged from 4.9% (95% CI: 1.6–8.1) in South–East Asia to 18.2% (95% CI: 10.9–25.5) in the Western Pacific region, the EPP of hyperopia ranged from 2.2% (95% CI: 1.2–3.3) in South-East Asia to 14.3% (95% CI: 13.4–15.2) in the Americas, and the EPP of astigmatism ranged from 9.8% in South-East Asia to 27.2% in the Americas. In adults, the EPP of myopia, hyperopia, and astigmatism was 26.5% (95% CI: 23.4–29.6), 30.9% (95% CI: 26.2–35.6), and 40.4% (95% CI: 34.3–46.6), respectively. The EPP of myopia ranged from 16.2% (95% CI: 15.6–16.8) in the Americas to 32.9% (95% CI: 25.1–40.7) in South-East Asia, the EPP of hyperopia ranged from 23.1% (95% CI: 6.1%–40.2%) in Europe to 38.6% (95% CI: 22.4–54.8) in Africa and 37.2% (95% CI: 25.3–49) in the Americas, and the EPP of astigmatism ranged from 11.4% (95% CI: 2.1–20.7) in Africa to 45.6% (95% CI: 44.1–47.1) in the Americas and 44.8% (95% CI: 36.6–53.1) in South-East Asia. The results of meta-regression showed that the prevalence of myopia increased from 1993 (10.4%) to 2016 (34.2%) (P = 0.097).ConclusionThis report showed that astigmatism was the most common refractive errors in children and adults followed by hyperopia and myopia. The highest prevalence of myopia and astigmatism was seen in South-East Asian adults. The highest prevalence of hyperopia in children and adults was seen in the Americas.
