Myopia and its relation with Central Corneal Thickness (CCT) & Intraocular Pressure (IOP).
Ophthalmol Update Jan ;12(1):52-4.

Objective: To determine the relationship of myopia with central corneal thickness (CCT) and intraocular pressure (IOP). Study design: Prospective, descriptive observational study Material and Methods: The study was conducted from November 2011 to October 2012. A total of 400 eyes of 200 myopic patients were included in the study. Measurements of refractive status were detected by autorefractor and then confirmed by retinoscopy and spherical equivalent, was calculated of astigmatic patients. Patients were divided into three groups depending the amount of myopia as group I (-0.5 to -3.0D), group II (-3.25 to -6.0D) and group III (-6.25 or more). The IOP was measured with Goldman applanation tomometer. CCT was measured with pachymeter. Results: In 400 eyes 55.75% were male and 44.25% were females. The incidence of mild myopia was 74.25%, moderate myopia was 20% and high myopia was 5.75%.The mean CCT and IOP in group I was (CCT=548.5+31.24, IOP=15.40+2.75), groupII ( CCT=539.3+ 30.74, IOP= 15.63+ 2.72), group III (542.7+ 30.87, IOP=16.12+2.84). No significant relationship of myopia was established with CCT (r=0.18, p>0.05) and IOP (r=0.03, p>0.05).
