We present our experience with three patients, two of whom were women, 16, 28 and 44 years of age, presenting with leiomyomas of the ciliary body. Salient clinical features were involvement of the left eye and temporal quadrants in two cases and extension into the anterior chamber in the other. Two patients underwent enucleation and the third had iriclocyclochoroidectomy. Immunohistochemical studies showed strong positivity for muscle-specific actin, smooth muscle actin and desmin, whereas staining against vimentin, HMB-45 and S-100 protein was negative. Although there are no specific clinical or imaging signs for intraocular leiomyoma, this tumor should be suspected when pigmented ciliary body tumors are encountered, especially in young female patients.
