Unexpected Intraocular Migration of a Cilium During Pars Plana Vitrectomy

Background

The presence of an intraocular cilium was reported for the first time by Lerche in 1835 [1]. Since then, intraocular cilia have been observed in different anatomical parts of the eye: the anterior chamber [2], [3], [4], [5], the iris [5], the posterior chamber [6], the vitreous [7], [8], as well as the retina [9], [10]. Most of the time, the presence of intraocular cilia has been linked to a history of penetrating trauma or migration during anterior segment surgery. However, in several reports the exact mechanism of how the cilium had entered the eye remained unknown [7], [8], [10]. In contrast to the previous reports we describe herein the case of a peroperative posterior migration of a cilium into the vitreous cavity.
