Corneal thickness affects glaucoma severity


Thinner corneas could be linked to higher glaucoma severity.

Thinner corneas could be linked to higher glaucoma severity, claims a paper in the journal Eye.

Dr M. Iester et al., Clinica Oculistica, University of Siena, Siena, Italy, included 816 glaucoma patients from 16 various glaucoma centres. The outcome measures were CCT, ophthalmoscopic cup/disc ratio, mean deviation (MD), pattern SD (PSD) and IOP. The difference between paired eyes was calculated for all parameters. Three different CCT cutoffs, 10, 15, and 20 μm, were chosen.

The 20 μm subgroup demonstrated no significant difference in IOP between the paired eyes. However, there was a significant difference in MD, PSD and cup/disc ratio. There were nosignificant differences between CCT and the remaining parameters.

It was concluded that CCT between the two eyes could be linked to a more severe glaucoma in the eye with the thinner cornea.
