An eyelash in the vitreous cavity without apparent etiology.

Intraocular eyelashes are an infrequent complication of trauma to the eye. Intraocular cilia have a variable prognosis ranging from acute inflammation to remaining dormant within the vitreous for several years. However, intraocular cilia in the anterior chamber have been associated with delayed inflammatory responses, while intravitreal cilia may cause rhegmatogenous retinal detachment. All cases reported in the literature to this point have been able to identify some history of trauma, be it acute or remote. In this report a case is described in which intravitreal cilia were not associated with a history of trauma.
