| Abstract | ||
| Introduction: Keratoconus is the most common primary corneal disease. It is a bilateral ectatic corneal degeneration characterized by localized corneal thinning which leads to protrusion of the thinned cornea. Patients and Methods: Study design: A retrospective comparative study. Ethical considerations: The Local Research Ethics Committee, Faculty of Medicine, Minia University approved this study. The study adhered to the tenets of the Helsinki Declaration. Results: Demographic Data: The mean age of the entire cohort was 29.2±7.7 years (range: 18-54 years). Fifty-four patients (35.6 %) were males and 96(64.4%) were females. Fifty patients (33.33%) had clinical keratoconus, 50(33.33%) were keratoconus suspects and 50(33.33%) were normal subjects were recruited and included in the analysis. The mean age of the clinical keratoconus group was 29.2 ± 7 years (range 19-52 years). Twenty-six patients (52%) were males and 24(48%) were females. The mean age of the keratoconus suspect group was 30.7 ± 8.9 years (range 19-52 years). Thirteen patients (26%) were males and 37(74%) were females. The mean age of the normal control group was 27.6 ± 6.9 years (range 18-41 years). Fifteen subjects (30%) were males and 35(70%) were females. There is a significant difference in vertical coma, spherical aberrations, RMS HOA and RMS of total aberrations between the 3 groups. And there is a significant difference in RMS HOA and RMS of total aberrations between the KCS and normal group. | ||
