목적 : To describe and compare posterior topographic elevation maps in glaucoma patients with functional damage staging and in healthy controls.
방법 : A total of 43 eyes were diagnosed with glaucoma and 36 eyes of normal subjects were included into this study.11 primary open angle glaucoma patients, 17 normal tension glaucoma patients were included into study group. All subjects were evaluated with a Galilei scheimpflug camera(Ziemer Group, Port, Switzerland). Posterior topographic elevation maps were compared in the central 3, 6, and 9mm. Humphrey automated perimetry results from the patient group were classified according to the Glaucoma Staging System 2.
결과 : Average age of the study group was 55.29-year-old, and for the control group was 33.06-year-old. Maximum elevation reading in the central 3 mm was significantly(P < 0.05) higher in the posterior (patients: 15.40 ± 6.01; controls: 8.89±3.28) corneal topography of the glaucomatous patients, as well as in the posterior (patients: 95.16 ± 64.78; controls: 57.92 ± 24.53) central 9 mm. There was a weak but significant correlation between the Glaucoma Staging System 2 stage and both the posterior 9mm maximum(r=0.316) and 9mm difference(r=0.280).
결론 : In patients with glaucoma, there is a forward shifting of the posterior corneal surfaces. This result appears to be closely associated with more severe stages of functional damage.
