PURPOSE: To evaluate the results of short wavelength perimetry (SWAP) of ocular hypertensive (OHT) patients and correlate these findings with central corneal thickness (CCT) measurements. METHODS: Thirty-seven OHT patients with a mean age of 50.2 ± 8.2 (SD) years and 30 control subjects with a mean age of 50.3 ± 8.5 (SD) years were included in this study. A questionnaire was applied to patients to evaluate the demographic risk factors that may predict glaucoma development. After a detailed ophthalmologic examination, achromatic and short wavelength perimetries and ultrasonic pachymetry were performed and the results were compared between the two groups with Student t test and Mann-Whitney U test. A p value of < 0.05 is considered as statistically significant. RESULTS: Mean CCT was higher in the OHT group (right eye; 558.13 ± 28.39 μm and left eye; 558.94 ± 27.30 μm) when compared with the control subjects (524.66 ± 30.53 μm and 525.86 ± 30.46 μm, respectively) (p < 0.01). A significant positive correlation was found between CCT measurements and intraocular pressure (r = 0.5, p < 0.001). Four right eyes (10.8%) and five left eyes (13.5%) of OHT patients had defects in SWAP. OHT patients with SWAP abnormalities had significantly lower CCT measurements in right (527.25 ± 17.34 μm) and left eye (528.80 ± 13.60 μm) when compared with OHT patients without SWAP defects (561.87 ± 27.29 μm and 563.65 ± 25.92 μm, respectively) (p < 0.05). Significant correlations were found between CCT and SWAP MD, PSD, and CPSD (p < 0.05). CONCLUSIONS: OHT patients with SWAP abnormalities had significantly lower CCT measurements than those without. CCT is considered as a risk factor for the development of glaucomatous damage in OHT patients.
