    Abstract:
    OBJECTIVE: To determine the morphologic changes and their clinical significance of cyclodialysis. METHODS: 173 eyes of 173 patients with cyclodialysis were examined by ultrasound biomicroscopy (UBM) for the morphologic changes, and the measurements of relative parameters were analyzed statistically. RESULTS: The cyclodialysis in all the cases was 360 degree. The characteristic manifestations of cyclodialysis found by UBM were as follows: no echoes between sclera and ciliary body, anterior displacement and rotation of ciliary process and displacement of pars plana toward the centre of eyeball. Superciliary effusion could be observed in some cases. In some patients, the ciliary body may be completely disintegrated from the scleral spur, but the disintegration may be quadrantal instead of 360 degree, resulting in a fistula between anterior chamber and superciliary cavity. The anterior chamber depth of the affected eye (2,115 +/- 589) microm was markedly shallower than that of the normal eye (2,736 +/- 441) microm (t = 4.49, P < 0.001). The shallowing of anterior chamber was caused by the anterior displacement and rotation of ciliary processes and the resulting anterior bulging of the iris root. CONCLUSIONS: UBM can be used to make a correct diagnosis of cyclodialysis irrespective of optic media condition, and can provide evidences for treatment.
