초음파 생체현미경을 이용한 조절에 따른 섬모체고랑거리, 전방깊이, 전방각의 변화 비교
이승찬,진경현.Seung-Chan Lee. M.D.. Kyung-Hyun Jin. M.D. 대한안과학회 2005 대한안과학회지 Vol.46 No.11
Purpose: To evaluate changes in the ciliary sulcus size, anterior chamber depth (ACD) and anterior chamber angle (ACA) during accommodation using an ultrasound biomicroscope (UBM). Methods: Twenty-seven eyes of 27 healthy subjects were studied. We examined refractive error and intraocular pressure, measured the horizontal distance of the ciliary sulcus, ACD, and ACA at distant fixation and near fixation using a UBM (50 MHz transducer, model P45 UBM plus, Paradigm?, Kent, U. K.). Results: The subjects included 16 males and 6 females. The mean age of the subjects was 20.5 years (age range, 19-22 years), and mean spherical equivalent was -2.86±1.67 diopters. At distant fixation, horizontal ciliary sulcus size was 11.75±0.56 mm, ACD was 3.15±0.17 mm, and ACA was 38.5±4.2°. At near fixation, horizontal ciliary sulcus size was 11.34±0.65 mm, ACD was 2.92±0.15 mm, and ACA was 44.5±5.7°. Conclusions: During accommodation, horizontal ciliary sulcus size and ACD significantly decreased and ACA increased in the patients.

Purpose: To report the change of anterior chamber parameters according to cataract severity after cataract surgery and to determine its relationship to the severity of cataract by using anterior segment optical coherence tomography. Methods: We measured the anterior chamber parameters in 19 eyes of 14 patients before, 1 week after, and 1 month after cataract surgery by slit lamp-adapted optical coherence tomography (SL-OCT). The measured parameters were as follows : the anterior chamber depth (ACD), the angle-opening distance 250 μm from the scleral spur (AOD250), the angle-opening distance 500 μm from the scleral spur (AOD500), and the trabecular-iris angle (TIA). We analyzed the relationship between the severity of cataract and the change of the anterior chamber parameters. Results: The ACD, AOD250, AOD500, and TIA increased significantly at postoperative 1 week (P=0.000, 0.002, 0.005, 0.022) and 1 month (P=0.000, 0.004, 0.001, 0.002). The preoperative parameters were negatively correlated with the differences between the postoperative 1 week and preoperative parameters (γ=-0.834, -0.591, -0.421, -0.826) and between postoperative 1 month and preoperative parameters (γ=-0.659, -0.700, -0.770, -0.821). The change of parameters at postoperative 1 week (by N P=0.959, 0.916, 0.824, 1.000, by C P=0.454, 0.665, 0.578, 0.578) and 1 month (by N P=0.858, 0.973, 0.959, 0.959, by C P=0.999, 0.207, 0.950, 0.981) were not significantly different according to the severity of cataract (N, C). Conclusions: Our results showed that cataract surgery significantly deepened the anterior chamber and widened its angle. The shallower and narrower the preoperative anterior chamber depth and angle were, respectively, the greater the postoperative changes of anterior chamber depth and angle were.
