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(R), 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. |
