Variation in corneal curvature in rigid gas permeable contact lens wearers

This work presents a study of corneal curvature changes in patients wearing rigid gas permeable contact lenses. For each patient we recorded the [K] reading before fitting and after wearing the lenses at regular intervals during the follow-up period

Occurrence of superinfection in herpes simplex keratitis

In this work we study the occurrence of secondary infections in patients suffering from herpes simplex keratitis. We discuss the detection of this condition and the various common factors predisposing to superinfection

Incidence of anisometropic amblyopia in children

One thousand, eight hundred and fifty four children up to twelve years old were refracted under cycloplegic inorder to find out cases with a diffrence in refraction between both eyes one diopter or more, this difference was found in 263 cases, so the incidence of anisometropia in children was 14.19%, females were affected more than males, consanguinity present in 19.77% of cases, myopic anisometropia was common than hypermetropic and mixed types. After optical correcion we found that 109 cases were amblyopic, so incidence of amblyopia was 43.43% among anisometropic children, hypermetropic anisometropic cases more affected with amblyopia than others
