Abstract
BACKGROUND: To report on procedure-related anterior segment complications during intravitreal injections. METHODS: In a prospective interventional case series, 614 eyes received a total of 723 intravitreal injections of about 20 mg triamcinolone acetonide (in 0.2 ml) after paracentesis and aqueous humor drainage for various indications. RESULTS: In three eyes (0.49% of all eyes) a vitreous prolapse occurred during the injection. In one eye, the vitreous prolapse was combined with dislocation of the intraocular lens (IOL). All three eyes were pseudophakic, showing an posterior capsule defect, and the IOL located in the ciliary sulcus. They were treated by translimbal vitrectomy, and one eye with reposition of the IOL. No other procedure-related postoperative complications were observed during injection or follow-up (7.8+/-7.1 months). CONCLUSIONS: Intravitreal injections may cause a vitreous prolapse into the anterior chamber with or without IOL decentration or dislocation in predisposed eyes. Ophthalmologists should be aware of this possible complication and inform patients at risk.
