“…It has been shown that ciliary bodies of eyes with narrow angle are thinner than those of normal control eyes. 10 In addition, the mean age (51.8 ± 16.5 years) in Oliveira et al's study was relatively high. 13 Previous studies of the ciliary body, including the histologic studies, have documented a significant reduction of the area of the ciliary muscle due to atrophy, 14,15 and a significant change in configuration of the ciliary muscle with 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.

“…Regarding the CBT2, our data did not show any statistically significant difference either between the two groups or within the groups between light and dark conditions. Gohdo et al (23) , found a thinner ciliary body in narrow angle eyes in comparison to normal control eyes, and suggested that this thinning could be an age-related change.…”

“…Marchini showed high reproducibility in a paper comparing UBM parameters in angle closure patients (range of coefficient of variation 1.4 -16%) (Marchini et al, 1998). Even better reproducibility was reported by Gohdo when measuring the ciliary body thickness (CBT) one and two millimeters posterior to the scleral spur (coefficient of variation < 2.5%) (Gohdo et al, 2000).…”
