Corneal thickness and corneal endothelium in normotensive subjects with unilateral exfoliation syndrome

Abstract

Normotensive eyes with early EXS did not have quantitative (cell density) or qualitative (variation in cell size, frequency of hexagonal cells) morphological changes in corneal endothelium, but had higher values for IOP and CCT. After correcting IOP for CCT, the E eyes still had significantly higher IOP than the fellow NE eyes.

Ocular response analyzer to assess corneal biomechanical properties in exfoliation syndrome and exfoliative glaucoma

“…Inoue et al reported that CCT of EXS eyes in patients without glaucoma (529±31 μm) was significantly lower than that of control eyes (547±28 μm) [27]. Puska et al however, found CCT to be higher in eyes with EXS than in the fellow eyes without EXS [28]. In the current study, there were no significant differences in CCT between the control eyes and exfoliative eyes with or without glaucoma.…”

Evaluation of Central Corneal Thickness and Corneal Endothelial Cell Parameters in Pseudoexfoliative Glaucoma

“…The mean percentage of hexagonal cells in PXG eyes in our study was 50.9 ± 2.47 which was in accordance to previous studies as 54.9 ± 10.9 [35], 56.4 ± 7.5 [35], 57.1 ± 7.1 [36]. The mean central corneal thickness in PXG patients has been reported as 493 ± 33 [37], 507 ± 25 [38], 528 ± 30 [39] which was comparable to our study group 556.4 ± 28.95. In our study there was a significant difference in the CCT in PXG patients compared to the normal group 572.5 ± 19.91.…”

Evaluation of anterior segment parameters in patients with pseudoexfoliation syndrome using Scheimpflug imaging

“…However, there are conflicting studies about central corneal thickness (CCT) in patients with PXS or pseudoexfoliative glaucoma. Most studies have reported similar CCT in PXS and normal eyes (9)(10)(11)(12)(13) , but some authors have reported a thinner (14,15) or thicker (16,17) CCT in PXS eyes than in normal eyes.…”
