“…In contrast to a previous report (Mishima et al 1996), we have found that the drug causes an increase in the thickness of the ciliary body. We hypothesize that this increase may be linked to widening of spaces in the ciliary muscle.…”

“…In addition, to minimize ciliary body configuration changes during accommodation, 11,22 we performed our UBM scanning 45 min after instillation of three drops of cyclopentolate 1%. Moreover, our study group was composed of predominantly young ages (mean age: 29.7 ± 10.3 years) who were not significantly in the presbyopic age.…”

“…6,7 Ultrasound biomicroscopy (UBM) allows in vivo, real-time imaging of the ciliary region, including structures not otherwise visible, and provides a digital image from which morphometric measurements can be readily made. [8][9][10][11][12] Although Oliveira et al 13 reported a positive correlation between AL and CBT, their measurements may be influenced by individual variability and age. [13][14][15] To minimize these influences in this study, we compared the CBT of eyes with unilateral high axial myopia with same subject's fellow eyes with relatively normal AL, using UBM.…”

Purpose To compare the thickness of the ciliary bodies of eyes with unilateral high axial myopia with their relatively normal fellow eyes. Methods A total of 19 patients with unilateral high axial length (AL) were included in the study. Mean patient age was 28. 4±10.4 (11-44) years. All eyes underwent ultrasound biometry to measure the AL, and ultrasound biomicroscopy to measure the anterior chamber depth, ciliary body thickness (CBT), and ciliary process thickness (CPT), ciliary muscle thickness (CMT). The results were compared between each subject's high myopic eye and relatively normal fellow eye. Results The mean AL was 27.24±1.52 mm (range: 25.16-30.21 mm) in high myopic eyes and 23.64 ± 0.86 mm (range: 22.47-25.10 mm) in normal fellow eyes. The median ± 95% confidence interval of CBT, CPT, and CMT was 1.350±0.034, 0.626±0.072, and 0.698±0.057 mm, respectively, in high myopic eyes and 1.211±0.050, 0.535±0.064, and 0.644±0.065 mm, respectively, in normal fellow eyes. The anterior chamber depth, CBT, CPT, and CMT were significantly higher in myopic eyes compared with their relatively normal fellow eyes (Po0.05). CMT significantly increased with age in both groups (Po0.05). There was no significant correlation between age and CBT in both the groups (P40.05). Conclusion The CBT, CMT, and CPT are significantly higher in eyes with unilateral high axial myopia than in their relatively normal fellow eyes.
