Abstract

Purpose : To analyze the correlation between the severity of dry eye and the indices of videokeratography in Korea.

Methods : We evaluated the degree of dry eye (grade 1-3) in 193 patients (386 eyes) who have clinically diagnosed dry eye according to the Korean guidelines. Using Tomey TMS-4 videokeratography, we obtained the regularity indices such as surface regularity index (SRI), surface asymmetry index (SAI), visual acuity index (PVA) and irregular astigmatism index (IAI). The relationship between each index and dry eye severity was determined using Pearson correlation analysis.

Results : The higher was the severity of dry eye, the more positive correlations were found. The correlation of each index is as follows: SRI(r=0.331, p<0.001), SAI(r=0.273, p<0.001), PVA(r=0.325, p<0.001), IAI(r=0.292, p<0.001).

Conclusions : The regularity indices of the Tomey TMS-4 in dry eye patients have significant correlations with the severity of dry eye, so we may use them as objective tool for dry eye.
