Materials and Methods: The amblyopic and fellow eyes of 30 anisometropic amblyopic patients who were admitted to the eye clinic of Ulucanlar Eye Education and Research Hospital, between the dates of January to June 2014 were included to study. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg) and cornea-compensated intraocular pressure (IOPcc) values were determined by ocular response analyser (ORA, Reichert;USA).
Results: The mean CH value was 10.4±1.7 (7.8-14.8) mmHg in healthy eyes and 13.3±3.7 (8.8-22.7) mmHg in amblyopic eyes. The mean CRF value was 9.9±1.6 (6.2-13.4) mmHg in healthy eyes and 10.0±1.5 (6.3-13.2) in amblyopic eyes. The mean IOPcc value was 14.6±3.6 (7.6-22.1) in healthy eyes and 14.5±3.6 (8.8-22.7) in amblyopic eyes. The mean CH value and the mean CRF value were higher (p=0,001, p<0,001 respectively), and the mean IOPcc value was lower (p<0,001) in amblyopic eyes compared with fellow eyes of patients. There were no statistically signifi cant difference between the amblyopic and fellow eyes of patients in the terms of mean IOPg values and mean CCT values (p=0.82, p=0,44 respectively).
Conclusion: It was observed that CH and IOPcc values were signifi cantly low in amblyopic eyes compared to fellow eyes of the same patients, whereas CRF values were high. However, there were no signifi cant differences in CCT and IOPg values.
