To find the correlation of Central Corneal
Thickness(CCT) to degree of myopia and compare it with
Prospective study, the CCT of 50 myopic eyes from
myopic patients and 50 emmetropic eyes from control
group was measured using ultrasound pachymetry at
Ophthalmology department, Saveetha Hospital.
The mean myopic spherical equivalent was -2.5D,
range -0.75D to -4.25D. the mean CCT of emmetropic
group was 577.2 micrometer and the mean CCT of
myopic group was 558.54micrometer. The mean CCT
between myopic and emmetropic group was statistically
significant. There was correlation between CCT and
degree of myopic spherical equivalent .
This study showed that there was some difference in
CCT between emmetropes and myopic eyes (P=0.0011).
As myopic degree increases central corneal thickness
decreases. (On correlation, value is -0.2039)
