Photoreceptor status after resolved macular edema in branch retinal vein occlusion treated with tissue plasminogen activator.
OBJECTIVE
To evaluate the integrity of photoreceptors in macular edema (ME) associated with branch retinal vein occlusion after intravitreal tissue plasminogen activator.


METHODS
Retrospective, interventional case series.


METHODS
Nineteen eyes with ME by branch retinal vein occlusion were treated with intravitreal tissue plasminogen activator injection. We assessed visual acuity (VA) and the presence or absence in the fovea of a third high reflectance band (HRB) by optical coherence tomography at the final visit.


RESULTS
No differences were found in age, preoperative VA, and foveal thickness between the groups with or without the third HRB. After treatment, the mean VA improved significantly (P < .05) in both groups. At the final visit, the mean VA in the group without HRB was significantly poorer than the group with HRB (P = .0042); foveal thickness did not differ between the groups.


CONCLUSIONS
The integrity of the third HRB in the fovea is associated with VA after the resolution of ME.
