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 of age, were recruited CBT was measured from ultrasound biomicroscopy, at CBT1, CBT2 mm posterior to sclera spare. 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, group B (8 patients) of emmetropic eyes. Results: Thicker measurements at CBT1 (P < 0.001) and CBT2 (P = 0.003) were associated with increasingly myopic refractive errors and were associated with longer axial lengths. Conclusion : Thicker ciliary body measurements were associated with myopia and a longer axial length.
