Prevalence of amblyopia and refractive errors among primary school children

Journal of Ophthalmic and Vision Research, 2015

Purpose: To determine the prevalence of amblyopia and refractive errors among 7 to 12-year-old primary school children in Tehran, Iran. Methods: This population-based cross-sectional study included 2,410 randomly selected students. Visual acuity was tested using an E-chart on Yang vision tester. Refractive errors were measured by photorefractometry and cycloautorefraction. Strabismus was checked using cover test. Direct ophthalmoscopy was used to assess the anterior segment, lens opacities, red reflex and fundus. Functional amblyopia was defined as best corrected visual acuity ≤20/40 in one or both eyes with no anatomical problems. Results: Amblyopia was present in 2.3% (95% CI: 1.8% to 2.9%) of participants with no difference between the genders. Amblyopic subjects were significantly younger than non-amblyopic children (P=0.004). Overall, 15.9% of hyperopic and 5.9% of myopic cases had amblyopia. The prevalence of hyperopia ≥+2.00D, myopia ≤-0.50D, astigmatism ≥0.75D, and anisometropia (≥1.00D) was 3.5%, 4.9%, 22.6%, and 3.9%, respectively. With increasing age, the prevalence of myopia increased (P<0.001), that of hyperopia decreased (P=0.007), but astigmatism showed no change. Strabismus was found in 2.3% of cases. Strabismus (OR=17.9) and refractive errors, especially anisometropia (OR=12.87) and hyperopia (OR=11.87), were important amblyogenic risk factors. Conclusion: The high prevalence of amblyopia in our subjects in comparison to developed countries reveals the necessity of timely and sensitive screening methods. Due to the high prevalence of amblyopia among children with refractive errors, particularly high hyperopia and anisometropia, provision of glasses should be specifically attended by parents and supported by the Ministry of Health and insurance organizations.

Prevalence of refractive errors among school children of 6-12-years of age group and reason for not using spectacles even after correction

International Journal of Research in Medical Sciences, 2018

Background: As your eyes are one of the most important organ in the human body and vision is one of the most wonderful gift. But often many people neglect the importance of eye care and do not pay proper attention towards eye care. An estimated 180 million people world- wide are visibly disabled, of whom nearly 45 million are blind, four out of five of them live in developing countries. Blindness is one of the most significant social problems in India with uncorrected refractive errors as the second major cause accounting for 19.7% of blindness and low vision. 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 errors is relatively simple and is one of the easiest ways to reduce impaired vision. Three main types are considered as refractive errors: hypermetropia (farsightedness), myopia (nearsightedness) and astigmatism.Methods: Th...

Prevalence of Amblyopia among Government Middle School Children in City Of Lahore, Pakistan

scopemed.org

Amblyopia is a problem faced in all age groups in our society. It leaves great effects on the social, economical, behavioral, educational, physical and psychological aspects of a community. In this study we have determined prevalence, gender distribution, laterality & proportion of amblyopia and its various types among government middle school children in city of Lahore. In this study 200 students, 100 male and 100 female of Class 6 th , 7 th & 8 th from two Government Schools were analyzed. Visual Acuity of all the students was checked. Students with Organic blindness & Mental retardation were excluded. Objective & subjective refraction of all the students having visual acuity 6/12 or less was carried out. Diagnostic criteria for amblyopia were best-corrected visual acuity of 6/12 or less, in one or both eyes or bilateral difference of at least two best-corrected visual acuity lines. The results revealed that out of total 200 students 23(11.5%) had refractive errors and 6(3%) were amblyopic. Out of these 6(3%), 2(1%) were boys and 4(2%) were girls. 3(1.50%) students had unilateral and 3(1.50%) had bilateral Amblyopia. Meridional Amblyopia was found to be the most predominant type of Amblyopia being 3(1.5%) while Ametropic, Anisometropic and Strabismic type of Amblyopia were 1(0.5%) each. This data supports the assumption that vision screening of school students in our country can be useful in detecting correctable causes of decreased vision especially refractive errors which may otherwise lead to amblyopia causing long term visual disability.
