简介
PURPOSE
The aim of this study was to measure ocular hysteresis and corneal resistance factor (CRF), novel methods of analysing ocular rigidity/elasticity and to determine the relationship between central corneal thickness (CCT), hysteresis and CRF in normal subjects.
DESIGN
Prospective, cross-sectional, clinical trial.
PARTICIPANTS
The study included 207 normal eyes.
METHODS
Hysteresis and CRF were measured by the ocular response analyser. The CCT was measured using a hand held ultrasonic pachymeter.
MAIN OUTCOME MEASURES
Ocular hysteresis and CRF in normal patients and their relationship with CCT.
RESULTS
The mean hysteresis was 10.7±2.0mmHg standard deviation (S.D.) (range 6.1–17.6mmHg); the mean CRF was 10.3±2.0 (range 5.7–17.1mmHg). The mean CCT was 545.0±36.4μm (471–650μm). The relationship between hysteresis and CCT; CRF and CCT; CRF and …
