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.
