STRUCTURAL GLAUCOMATOUS DAMAGE AND OCULAR BIOMETRIC PARAMETERS

Abstract

Abstract: : Purpose: To investigate the correlation between morphological glaucomatous damage, central corneal thickness (CCT) and scleral thickness in POAG eyes. Methods: : 44 eyes of 44 POAG patients (23 males, 21 females; mean age 58.7±5.4) underwent complete ophthalmologic examination, CCT measurements with ultrasound pachimetry (Tomey SP 2000), scleral thickness measurements performed in the temporal sector at 3 mm from scleral spur with UBM and RNFL thickness evaluation using OCT3. Statistical analysis was performed with Pearson’s r and linear regression analysis to evaluate the correlation between the three parameters included in the study. A value p<0.05 was considered statistically significant. Results:The mean value of RNFL thickness performed using the OCT3 RNFL thickness average analysis was found to be 78.7±10.3 µ The mean value of CCT measured with ultrasound pachimetry was 546.8±28.5 µ. A statistically significant correlation between scleral thickness and CCT was also found. In our study performed on POAG eyes the CCT and scleral thickness correlate (p<0.05) with RNFL thickness measurements. Conclusions:These results suggest that the extent of RNFL injury in POAG eyes may be related to some ocular biometric parameters.
