Is there a predisposition for developing corneal hydrops in keratoconus?-Tomographic and biomechanical analysis of the fellow eyes.

Aim: Fellow eyes (FE) of 73 keratoconus (KC) patients with acute corneal hydrops (ACH) and 130 KC patients without ACH (total 236 eyes, 110 more severely affected), serving as control groups, were retrospectively analysed to identify potential risk factors associated with the development of ACH.

Methods: Tomographic (Pentacam) and biomechanical analysis (Corvis ST, both Oculus, Germany) were performed. Tomographic parameters are as follows: K-max, thinnest corneal thickness (TCT), Belin/Ambrósio deviation (BAD-D) and the tomographic ABCDE-staging.
