Abstract
In children and adolescents around the world, refractive errors (RE) are the most frequent cause of visual impairment and disability. Blurred vision is caused by refractive errors, which are a mismatch between the axial length and optical power of the eye. There are three primary categories of refractive errors: astigmatism, which is associated with an optical asymmetry, and hyperopia and myopia, which are referred to as spherical errors. Astigmatism is regarded as a separate category, yet it can be a characteristic of both myopic and hyperopic eyes. Aim : To perform a screening for refractive errors among primary school children in Alexandria, Egypt. Patients and Methods : Measuring monocular uncorrected (UCVA) and best-corrected visual acuity (BCVA) with glasses for students wearing glasses using a Landolt broken ring self-illuminated chart at six meters in a semi-dark room for children ranging in age from 6 to 12 years old. Children with visual impairment in either eye were referred for: Detailed slit lamp ophthalmic evaluation, pupillary light reflex, ocular motility examination, ocular alignment was evaluated using the Hirschberg, cover-uncover, and alternate-cover tests. Cycloplegic refraction was assessed by an autorefractometer.
