Uveitis-glaucoma-hyphema syndrome: a late complication of posterior chamber lenses

The uveitis-glaucoma-hyphema (UGH) syndrome is a triad that rarely occurs in the late postoperative period after an extracapsular cataract extraction (ECCE) with implantation of a posterior chamber (PC) intraocular lens (IOL). Surgical techniques as well as IOL design can influence the incidence of the UGH syndrome. We describe two patients who developed an UGH syndrome respectively 5 and 6 years after an ECCE with implantation of a flexible closed-loop one-plane PC IOL of the Anis type. Intraoperatively, an envelope technique had been used. Although no tears had occurred, an asymmetrical bag-sulcus fixation of the IOL had been obtained, with manifest upward decentration of the IOL, probably eroding the ciliary sulcus by its closed loops, acting as a semi-rigid system.
