Use of Intracameral Tissue Plasminogen Activator During Uveitic Cataract Surgery

To report the outcomes of intracameral tissue plasminogen activator (tPA) use during uveitic cataract surgery.

Retrospective case series from a single United States tertiary center of 36 eyes from 31 consecutive patients with established uveitis who received intraoperative intracameral tPA during cataract surgery between 2016 and 2020.

Mean visual acuity (VA) improved from logMAR 1.0 ± 0.7 preoperatively to logMAR 0.7 ± 0.8 by POM12. VA improved from baseline postoperatively (POM1 p = 0.0002, POM6 p = 0.006 and POM12 p = 0.007). Minimal to no anterior chamber inflammation was achieved in 47.2% of the eyes by POW1 and 80.0% of the eyes by POM1. Mean clock-hours of posterior synechiae improved from 8.2 ± 3.8 preoperatively to 0.1 ± 0.6 by POM12. Six eyes developed hyphema and/or vitreous hemorrhage, four of which resolved spontaneously.

Adjunctive intracameral tPA during uveitic cataract surgery improves VA and intraocular inflammation, but risks postoperative hemorrhage. Intraoperative tPA as adjunctive anti-inflammatory therapy warrants randomized prospective studies.
