OBJECTIVES: To investigate corneal biomechanical properties and intraocular pressure (IOP) in patients with high myopic anisometropia. METHODS: Patients with high myopic anisometropia (n = 23) and emmetropic subjects (n = 55) were enrolled. Corneal hysteresis (CH), Goldmann-correlated intraocular pressure (IOPg), corneal resistance factor, and corneal-compensated IOP (IOPcc) were measured with Ocular Response Analyzer. Central corneal thickness was measured by optical coherence tomography. Zeiss IOL-Master determined the values of corneal refractive power and ocular axial length. RESULTS: Significant differences were presented in CH, IOPg, and IOPcc among the high myopic, contralateral, and normal eyes (analysis of variance, P<0.05). CH in high myopic eye was lower than that in the other two groups (post hoc, P<0.05), whereas IOPg and IOPcc in both eyes of anisometropic myopia were higher compared with the normal subjects (post hoc, P<0.01). CH was associated with central corneal thickness and axial length in high myopic eyes. All measured biometric parameters showed significant correlations between two eyes in high myopic anisometropia. CONCLUSIONS: High myopic eyes showed decreased CH, but not corneal resistance factor, which indicates that some aspects of corneal biomechanical properties may be altered in high myopic eye of anisometropia. It is also suggested that anisometropic eyes with different refractive errors do not share the same biomechanical properties, which may impact IOP measurement. |
