Abstract

PURPOSE: To update the surgical technique in which a vitrectomy is performed and a retinal branch vein is cannulated and infused with recombinant tissue plasminogen activator (RTPA) to treat central retinal vein occlusion (CRVO) in patients who present with very low visual acuity (VA).

METHODS: Twelve consecutive patients (12 eyes) with CRVO and low VA (logMAR >1.00) at presentation were treated using this method.

RESULTS: Cannulation of a peripapillary retinal vein and stable injection of RTPA was successfully performed without surgery-related complications in all 12 eyes. At 12 months after surgery, 8 of the 12 patients (67%) experienced at least one line of improvement in best corrected visual acuity; 6 of the 12 (50%) improved ≥5 lines and 2 (17%) improved ≥8 lines. After additional grid laser and/or subconjunctival or intravitreal corticosteroids, the mean decrease in central foveal thickness was 260 μm, and the mean total macular volume decreased from 12.10 mm(3) to 9.24 mm(3) . Four patients received panretinal photocoagulation to treat either iris neovascularization (n = 2) or neovascularization of the retina and/or disc (n = 2).

CONCLUSION: Administration of RTPA via a peripapillary vein using this updated technique provides an alternative or additional treatment option for patients with very low VA after CRVO.
