Propose: To determine and compare, the ciliary body thickness (CBT) of high axial myopia and relatively emmetropic eyes. Methods: Thirty eyes of 18 patients, [22 - 45] years old, were recruited, CBT was measured using ultrasound biomicroscopy, at one & two mm posterior to scleral spur (CBT1, CBT2). Cycloplegic refractive error was measured & axial length using ultrasound biometry was determined. Patients were divided into two groups, group A (10 patients) of high myopic eyes and group B (8 patients) of emmetropic eyes. Results: Myopic eyes with long axial length have thicker measurements at CBT1 (P < 0.03) and CBT2 (P = 0.005). Conclusion: Myopia with long axial length has thicker ciliary body measurements.
