두 가지 장비를 이용한 각막 지형도 검사의 비교

Abstract

Purpose: To compare the corneal measurements of Sirius and Pentacam in normal cornea and post-corneal refractive surgery patients. Methods: Subjects were tested by Pentacam (OCULUS, Wetzlar, Germany), and Sirius (CSO, Firenze, Italy). Measurements included central corneal thickness, thinnest corneal thickness, anterior chamber depth, anterior chamber volume, iridocorneal angle, corneal volume, pupil size, and curvature of cornea. Results: A total of 88 eyes from 44 patients were included in the present study. When comparing Sirius and Pentacam in the normal cornea, corneal thickness (p = 0.693), thinnest corneal thickness (p = 0.386), anterior chamber depth (p = 0.155), anterior chamber volume (p = 0.650), and pupil diameter (p = 0.124) did not differ significantly. Corneal curvature (p < 0.001), corneal volume (p = 0.023), and iridocorneal angle (p < 0.001) were statistically different. When comparing Sirius and Pentacam in post-corneal refractive surgery patients, corneal thickness (p = 0.056) did not differ significantly. There was a statistical difference in corneal curvature (p < 0.001), thinnest corneal thickness (p = 0.019), anterior chamber depth (p < 0.001), anterior chamber volume (p < 0.001), iridocorneal angle (p < 0.001), corneal volume (p < 0.001), and pupil diameter (p < 0.001). Conclusions: Anterior segment measurements with Pentacam and Sirius showed differences in post-corneal refractive surgery patients.
