To evaluate biomechanical properties of the cornea in patients with congenital aniridia.
26 patients (16 women, 10 men) with congenital aniridia aged from 6 to 55 underwent corneal examination using Scheimpflug noncontact tonometry. CCT, deformation amplitude, first applanation time, second applanation time, highest concavity and IOP were evaluated.
CCT ranged from 496 μm to 718 μm (mean 623 μm). Deformation amplitude range from 0.36 to 1.01 mm (mean 0.62 mm) corelated with IOP result range from 15.6 mmHg to 42.8 mmHg (mean 22.82 mmHg).
Evaluation of corneal biomechanical properties is useful in estimation real IOP in aniridia patients.
