Brief Summary:
Refractive and Corneal Topographic Characteristics in upper Egypt children with high cylinder A cross sectional study
Detailed Description:
Astigmatism is defined as a refractive condition in which refractive light fails to form a focus on the retina it accounts for about 13 of refractive errors It is frequent and correctable cause of visual impairment in children whether associated with spherical errors or not
Astigmatism is the refractive error of the highest clinical importance being associated with reduced visual acuity with subsequent development of refractive amblyopia
High cylinder in children belong to areas of hot and dry climates makes exclusion of keratoconus is mandatory Population in the African continent the Mediterranean countries Central and South America and the Indian subcontinent usually have the habit of eye rubbing because of bothering symptoms of dryness itching atopy allergy and vernal keratoconjunctivitis which is the severe form of allergic conjunctivitis
Eye rubbing causes thinning of keratocyte and increases the prevalence of keratoconus
Keratoconus in children diagnosed before the age of eighteenth is less common but more aggressive than that of the adults due to the dynamic nature of the young cornea Few studies in the literature reported the prevalence and incidence of keratoconus in children
Pentacam is an advanced instrument with a rotating Scheimpflug camera for scanning the anterior and posterior corneal surfaces Its measurements of the corneal thickness and posterior elevation have been proved to be of high reproducibility and repeatability
