Purpose:
|
To determine the normative values of anterior chamber parameters measured by Pentacam and to evaluate their relationship with corneal hysteresis (CH) and corneal resistance factor (CRF).
|
|
Methods:
|
In an observational cross-sectional study, patients aged 18-35 years were included. Ocular Response Analyzer was used to measure CH and CRF. Corneal volume, anterior and posterior Q value, anterior and posterior elevation, central corneal thickness, corneal thinnest thickness, anterior chamber depth, anterior chamber volume and anterior chamber angle were measured with Pentacam

|
Results:
|
This study evaluated 408 eyes of 204 cases (126 females) with a mean age of 28.43 ± 6.36 years. The average CH and CRF were 10.07±1.61 and 10.33±1.68 mmHg. CH and CRF were not correlated to PQ, AQ, AE and PE. CH and CRF were significantly correlated with CCT (r=0.499, p<0.0001 and r=0.591, p<0.0001 respectively), CTT (r=0.469, p<0.0001 and r=0.593, p<0.0001 respectively) and CV (r=0.443, p<0.0001 and r=0.526, p<0.0001 respectively). The average ACD was 3.259±0.282 mm, ACV was 207.204±34.553 mm3 and ACA was 42.147±5.476?.

Conclusion:
|
A significant positive correlation was found between CH and CRF, and CCT, CTT and CV. This study also provided data about wide range normative values of corneal parameters
