COMPARATIVE STUDY BETWEEN THE CORNEAL VOLUME IN MILD AND SEVERE KERATOCONIC EYES USING PENTACAM TOMOGRAPHY

Abstract
ABSTRACT
Background: Keratoconus is the most common corneal ectasia. It usually appears in the second decade of the life and affects both genders and all ethnicities. Tomographic-based data have added significantly more information to the screening of corneal ectasia. In addition to anterior corneal analysis, tomography also provides information about the posterior cornea and the pachymetric distribution, which can increase our ability to identify early and subtle corneal changes.
Aim of the Work: The main aim is to determine how the corneal volume measurement changes in different diameters of corneal tissue, in the central 3 mm and 5 mm in mild and severe cases of keratoconus; in an attempt to quantify the loss of corneal tissue in keratoconus.
Patients and methods: This cross-sectional study included 20 eyes of keratoconic patients, from 15 to 36 years old. They were divided into 2 groups, each group included 10 eyes: Group A: mild keratoconic cases with steepest keratometry reading lower than 45 D. Group B: severe cases with steepest keratometry greater than 52 D, All cases were diagnosed as keratoconus using pentacam parameters.
Results: Corneal volume at 3 and 5 mm diameter was significantly lower in the severe keratoconic cases than in mild cases (P<0.01).
