Ultrasound Biomicroscopy of the Ciliary Body in Ocular/Oculodermal Melanocytosis
We read with great interest and attention the recent article from Velazquez-Martin and associates regarding the evaluation of ciliary body thickness in eyes of patients with unilateral ocular/oculodermal melanocytosis. They concluded that ciliary body thickness is increased in eyes affected with ocular/oculodermal melanocytosis in comparison with the fellow unaffected eyes. Although the measurements seem to be accurate and the results interesting, we believe that the statistical procedure used by the authors is not appropriate for their study design. Furthermore, some confounding factors were not taken into account that could have a direct effect on the significance of the results.
