Background:After extracapsular cataract extraction,the remaining epithelial cells near to t he equator may lead to the formation of a Soemmerings ring.Only 4cases of dis-location of the ring in the vitreous a re reported in the lit-erature.A spontaneous dislocation associated with a pha-colytic uveitis has not been describ ed before.History and signs:In 1999a 68-year-old man atte nded our clinic with a vision loss from 0.3to hand movement s in his left eye.For some years his right eye had been blin d after unsuccessful retinal detachment surgery.In his l eft eye conjunctival inflammation,anterior chamber fla re and complete occlu-sion of the pupil were found.Intraocular pressure was normal under hypotensive medicatio n.Ophthalmoscopy was not possible and ultrasound reveale d a ring-like dense structure in the vitreous cavity.Therapy and outcome:Pars plana vitrectomy showed a Soemmerin gs ring,which was successfully removed by pars plana f ragmentation.Forty-eight months postoperatively the patient had a visual acuity of 0.2in a healthy and normote nsive eye.Conclu-sions:Even years after cataract extraction a spontaneous dislocation of Soemmerings ring is p ossible.
Background: After extracapsular cataract extraction, the remaining epithelial cells near to he equator may lead to the formation of a Soemmerings ring. Only 4cases of dis-location of the ring in the vitreous a re reported in the lit-erature. A spontaneous dislocation associated with a pha-colytic uveitis has not been drawn yet? History and signs: In 1999a 68-year-old man atte nded our clinic with a vision loss from 0.3to hand movement s in his left eye .For some years his right eye had been blin d after unsuccessful retinal detachment surgery. In his l eft eye conjunctival inflammation, anterior chamber fla re and complete occlu-sion of the pupil were found. Intraocular pressure was normal under hypotensive medicatio n. Ophthalmoscopy was not possible and ultrasound reveale da ring-like dense structure in the vitreous cavity. Therapy and outcome: Pars plana vitrectomy showed a Soemmerin gs ring, which was successfully removed by pars plana f ragmentation. Forty-eight months postoperatively the patient had a visual acuity of 0.2 in a healthy and normote nized eye. Confluences: Even years after cataract extraction a spontaneous dislocation of Soemmerings ring is p ossible.
