Abstract Details


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.


Vision Health Research Center-Tehran-Iran


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.


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.


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