摘要
Objective: To evaluate the effect of central corneal thickness determination o n the clinical management of patients with glaucoma and glaucoma suspect. Method s: A cross- sectional retrospective study was performed on 188 consecutive patients. Mean ultrasound pachymetry measurements of central corneal thickness and correspondin g Goldmann applanation tonometry measurements were obtained. Intraocular pressur es (IOPs) were corrected using linear and mathematical (Orssengo-Pye) algorithm s. Measurement-significant outcomes were defined as an IOP adjustment of 1.5 mm Hg or greater and outcomes-significant results as an IOP adjustment of 3.0 mm Hg or greater. Changes in therapy such as the use of eyedrops and addition or ca ncellation of laser therapy or surgery were then noted for those individuals wit h measurement or outcomes-significant changes. Results: Using the linear correc tion scale, 105 (55.9%) of 188 patients had at least a measurement-significant adjustment in their IOP measurements: 67 (35.6%) had adjustments between 1.5 a nd 3.0 mm Hg, while 38 (20.2%) had an outcomes-significant IOP adjustment (≥3 .0 mm Hg). Among the 188 patients, 16 (8.5%) had a change in eyedrop therapy, 4 (2.1%) had a change regarding laser therapy, and 6 (3.2%) had a change in the decision regarding glaucoma surgery. Using the exponential correction (Orssengo -Pye) scale, similar percentages were obtained. Conclusions: Pachymetry-mea sured central corneal thickness has a significant effect on the clinical manag ement of patients with glaucoma and glaucoma suspect.
