Hence, a total ocular morbidity including refractive error was seen in 14.6%.DiscussionRefractive error is one of the avoidable causes of blindness and low vision. The 95% limits of agreement between the two methods were− 0.615 and +0.353 D in right-eye measurements, and −0.607 and +0.390 in left-eye measurements. Amblyopia was considered the cause of impairment in eyes with best corrected visual acuity of 20/40 or worse and no apparent organic lesion, so long as one or more of the Shrestha,K.S. http://supercgis.com/refractive-error/refractive-error-in-school-children-in-india.html
Presenting vision is defined by the visual acuity in the better eye unaided or using currently available refractive correction in spectacle wearers.

Jialiang (2000)4 in 12.8% in China, Trivedi (2006)11 in 2.7% in Gujrat, and Pokhrel (2000) in 1.62% in Jhapa. Refractive error study in children: results from La Florida, Chile. The majority of the children with blindness were female in both the studies. But, our study was limited to only few schools and sample coverage was poor.

The study was done after approval by Research and Publication Committee of the Department of Ophthalmology, Medical Faculty of Addis Ababa University. Pubmed Cycloplegic autorefraction was performed using a handheld autorefractor (Retinomax K-Plus; Nikon Corp., Tokyo, Japan), with calibration at the beginning of each day.

Effective strategies need to be devised to provide low cost corrective spectacles in the rural community.Keywords: Refractive error, visual acuity, visual impairment, childrenIntroductionRefractive error is one of the most common causes Geneva: WHO, 1997. 3. Clustering effects were taken into account in the calculation of confidence intervals for prevalence estimates and in regression analyses. We would like to thank Mr.

Prasad Eye Institute, Hyderabad, India.AbstractPURPOSE: To assess the prevalence of refractive error and related visual impairment in school-aged children in the rural population of the Mahabubnagar district in the southern Indian Prevalence Of Refractive Errors In Indian Children
Out of these, 54% were boys. Visual acuity was measured at 4 m, using a retroilluminated log minimum angle of resolution (MAR) chart with five E optotypes on each line (Precision Vision, La Salle, IL), and recorded The Mahabubnagar district has 64 mandals (administrative units) of which five mandals with villages within a 50-km radius of the rural eye center were chosen for the study.

In these clusters, all children with uncorrected visual acuity of 20/40 or worse in either eye and approximately 10% of other children had second evaluations of uncorrected visual acuity, retinoscopy, and The number of enumerated children per cluster ranged from 115 to 340. Of these 4414 children, 4074 were examined—a participation rate of 92.3%. Astigmatism of 0.75 D or more was found in 2.8% of right eyes and 2.9% of left eyes with retinoscopy.

In Pokhrel report, the prevalence of myopia was described as −0.5 diopter or less in either eye, hyperopia 2 diopters or greater in either eye, and astigmatism of 0.75 cylindrical diopter Table 4.

The other major causes of either unilateral or bilateral subnormal visual acuity were retinal causes, corneal opacity, and strabismic amblyopia with proportion of 10.8%, 8.1% and 5.4% respectively.
