Circumferential Pupillary Capture by IOL due to Intraocular Gas Tamponade: A Case Report

Abstract

A 55-years-old female presented with pain in the right eye for 15 days. She had a history of complicated cataract surgery followed by pars plana vitrectomy, intraocular gas injection and sulcus fixated intraocular lens implantation. On ophthalmologic examination, pupillary capture by intraocular lens, shallow anterior chamber, corneal edema and elevated intraocular pressure despite maximum medical therapy was observed. Intraocular gas induced secondary pupillary block glaucoma diagnosis was made. She underwent intraocular lens reposition and peripheral iridectomy surgery in the same session. Intraocular pressure reduced dramatically after the procedure in addition to anterior chamber deepening. In this case report, we highlighted the very rare cause of pupillary block glaucoma and its management.

Temporal Change in Anterior Chamber Depth after Combined Vitrectomy and Cataract Surgery Using Different Sizes of Intraocular Lens

“…We were concerned that a small ACD (i.e., forward shift of IOL) increases the risk of complications. Posterior synechia or pupillary capture after gas tamponade has been reported [ 16 , 17 ]; thus, complications should be considered in the early postoperative period of phacovitrectomy with SF6, especially in the 6 mm IOL.…”
