To evaluate the efficacy of intravitreal tissue plasminogen activator (tPA) with C3F8 injection for branch retinal vein occlusion (BRVO) involving fovea.
MethodsSeven patients (7 eyes) presenting with subfoveal hemorrhage caused by BRVO were treated with an intravitreal tPA and C3F8 injection. We assessed the visual acuity (VA) and foveal thickness measured with optical coherence tomography.
ResultsThe mean duration of symptoms before surgery was 5.42±1.90 weeks. The mean logMAR VA improved from 1.14±0.19 at baseline to 0.87±0.34 at one week and 0.30±0.32 at six months. The mean foveal thickness decreased from 564.421±186.88 µm at baseline to 483.14±275.06 µm at one week and 353.28±152.99 µm at six months. There was no adverse effect related to the treatment.
ConclusionsIntravitreal tPA with C3F8 injection may be an effective treatment for resolving macular edema with subfoveal hemorrhage and improving the VA in recently developed BRVO.
