Abstract Details

Purpose:

To compare the anterior and posterior corneal surface indices in corneal scaring and DMGK patients in order to find parameters for the separation of these two groups.

Setting:

Vision Health Research Center-Tehran-Iran

Methods:

This study included 20 and 19 eyes in DMGK and corneal scar groups, respectively. Corneal topography pattern and 24 parameters included anterior and posterior corneal surface indices from 4 maps refractive, Belin/Ambrosio Enhanced Ectasia and cornea densitometry maps evaluated.

Results:

The mean age was 49.64 and 51.60 years for DMGK and corneal scarring, respectively.More common topography patterns were superior steepening (65%) and irregular (75%) in DMGK and corneal scarring, respectively.Front eccentricity in DMGK was significantly more than in corneal scaring (p=0.004). Chamber volume and anterior chamber depth were more in corneal scaring group (p=0.003, p=0.003). Densitometry indices in anterior layer, 6-10 mm and 10-12 mm of the cornea were significantly lower in scar group (p<0.001, p<0.001, p=0.001). It was observed that 0-2 mm densitometry of the cornea was significantly lower in DMGK group.

Conclusions:

Topography pattern, densitometry indices, eccentricity, chamber volume and anterior chamber depth using Pentacam tomography are good parameters that can discriminate DMGK and scar corneas.
