GATA Göz Hastanesi A.D., Ankara Purpose: To investigate the correlation between central corneal thicknesses (CCT), intraocular pressure (IOP) and visual field defects in eyes with glaucoma and ocular hypertension.

Materials and Methods: The study included 498 eyes of 254 glaucoma and ocular hypertension subjects that had comprehensive ocular examination, reliable and reproducible Swedish interactive thresholding algorithm standard perimetry, IOP measurements with Goldman applanation tonometry and CCT measurements with ultrasonic pachymetry. Patients were evaluated as Ocular hypertension (OHT), primary open angle glaucoma (POAG), secondary open angle glaucoma (SOAG), normotensive glaucoma (NTG) and primary angle closure glaucoma (PACG).

Results: The mean CCT in OHT patients was significantly higher than in subjects with POAG, SAAG, and NTG (p<0.001). Average mean deviation and pattern standard deviation in OHT eyes were significantly lower than in eyes with either POAG, SOAG, PACG, or NTG (p<0.001). CCT was correlated with IOP measurements in NTG group (r=-0.538, p=0.002).

Conclusion: OHT patients have higher CCT values and lower glaucomatous visual field defects than POAG and SOAG patients. Central corneal thickness should be taken into account beside the other risk factors when assessing risk for the development of glaucomatous visual field defects. Keywords : Central corneal thickness, glaucomatous visual field defect
