Abstract

Purpose: To compare CENTRAL CORNEAL THICKNESS (CCT) in patients with OCULAR HYPERTENSION (OHT), PRIMARY OPEN-ANGLE GLAUCOMA (POAG), LOW-TENSION GLAUCOMA (LTG), and a control group.Materials and methods: All consecutive patients affected by OHT, POAG, or LTG examined at Farabi Eye Center, glaucoma clinic (Isfahan, Iran) who met the eligibility criteria were recruited. A control group consisting of hospital staff and patients examined at the general eye clinic who had a normal eye examination were also included. Exclusion criteria were: (1) history of previous corneal or intraocular surgery, (2) history of previous eye trauma or presence of significant corneal pathology, (3) contact lens wear, (4) myopia or hyperopia greater than 5 diopters or astigmatism exceeding 2.5 diopters, and (5) use of acetazolamide or dorzolamide within the previous month. CENTRAL CORNEAL THICKNESS was measured by an ultrasound pachymeter 3 times in each eye and the lowest measurement was chosen as the final value. Only measurements from the right eye of each binocular individual were included for further analysis.Results: A total of 125 eyes were examined consisting of 42 ocular hypertensives, 37 POAG cases, 6 cases with LTG and 40 normal eyes (control group). Mean (SD) CENTRAL CORNEAL THICKNESS was 562.9 (30.8), 528.4 (31.2), 502.8 (47.3), and 525.6 (26.0) microns in the OHT, POAG, LTG, and control groups, respectively. A statistically significant difference was detected between the OHT group and POAG and control groups (P= 0.000 for both comparisons). No statistically significant comparison was found for the LTG group because of the low number of cases. A CCT of 580 microns or more was present in 2.5%, 5.4% and 33.3% of the control, POAG, and OHT eyes, respectively (P= 0.000 for both comparisons).Conclusion: Some eyes with OHT have an abnormally thick cornea that may lead to overestimation of the intraocular pressure and probably undue treatment. Measuring CCT in all eyes with OHT is indicated.
