Abstract
Purpose
To report the safety and efficacy of intravitreal recombinant tissue plasminogen activator (rtPA) with gas for managing submacular hemorrhage.
Methods
Patients with submacular hemorrhage centered in or close to the fovea underwent hemorrhage displacement with intravitreal injection of rtPA (50 μg/0.05 mL) followed by gas injection (0.3 mL SF6). Anatomic and visual outcomes are described.
Results
Exudative age-related macular degeneration (AMD) (n = 4) and blunt trauma (n = 2) were the etiologies of submacular hemorrhage in this sample. Intravitreal injection of rtPA decreased the extent of submacular hemorrhage in all eyes, with complete hemorrhage displacement in 2 and partial displacement in 4. Visual acuity remained stable (n = 4) or improved (n = 2) after the procedure. Improvements in anatomic and visual outcomes were less evident in exudative AMD cases, which also had longer hemorrhage duration. Recurrence occurred only in 1 eye. No evident rtPA-associated retinal toxicity was observed.
Conclusions
Untreated submacular hemorrhage has poor visual prognosis. Our results suggest that rtPA injection is a minimally invasive, simple, inexpensive procedure with few related complications. Cost-benefit of this injection seems acceptable.
