dc.description.abstractPurpose To compare the ciliary muscle thickness (CMT) of the normal fellow eye to that of the amblyopic eye using ultrasound biomicroscopy (UBM) in patients with unilateral anisometropic amblyopia. Methods Thirty patients with unilateral anisometropic amblyopia were involved. The patients were divided into two groups: 19 hyperopic and 11 myopic. Axial length (AL) was measured with optic biometry and anterior chamber depth (ACD), iris area, and CMT were measured with UBM. Results The mean age was 34.10 +/- 6.61 years. The mean spherical difference between two eyes was 2.59 diopter (D) in hyperopic patients and 3.77D in myopic patients. In the hyperopic patients, nasal CMT1(nCMT), temporal CMT1(tCMT), tCMT2, and tCMT3 values were statistically thinner in amblyopic eyes than healthy eyes (p = 0.036,p = 0.003,p = 0.023,p = 0.005, respectively). ACD values were statistically lower in amblyopic eyes (2.78 +/- 0.26 mm) than healthy eyes (2.90 +/- 0.21 mm) (p < 0.001). In the myopic patients, nCMT1, nCMT2, nCMT3, tCMT1, tCMT2, and tCMT3 values were statistically thicker in amblyopic eyes than healthy eyes (p = 0.003,p = 0.003,p = 0.005,p = 0.003,p = 0.003,p = 0.019, respectively). ACD values were statistically higher in amblyopic eyes (3.20 +/- 0.30 mm) than healthy eyes (3.06 +/- 0.29 mm) (p = 0.004). Also, there was no significant difference in the iris area between the amblyopic and normal eyes of the myopic and hyperopic patients (p > 0.05). Conclusions Amblyopic eyes in patients with unilateral myopic anisometropia have thicker CMT and deeper ACD than healthy eyes. Conversely, amblyopic eyes in patients with unilateral hyperopic anisometropia have thinner CMT and shorter ACD than healthy eyes. There is a positive correlation between AL and CMT.
