Subretinal tenecteplase injection in a submacular hemorrhage from polypoidal choroidal vasculopathy: a case report.
OBJECTIVE
The purpose of this report was to describe a case with a thick submacular hemorrhage (SMH) resulting from polypoidal choroidal vasculopathy that was successfully treated with a subretinal tenecteplase injection.


METHODS
A retrospective case report.


RESULTS
A 63-year-old man with acute SMH secondary to polypoidal choroidal vasculopathy underwent a partial posterior vitrectomy, a subretinal tenecteplase (100 μg/0.1 mL) injection with air/fluid exchange, and an intravitreal injection of bevacizumab (2.5 mg/0.1 mL). His preoperative corrected visual acuity was 20/30, but the SMH threatened the fovea. The SMH was displaced inferiorly and absorbed completely at 1 month postoperative. His visual acuity decreased to 20/40 1 week postoperative but recovered to 20/20 2 months after surgery. The electroretinogram showed no distinct elongation of implicit time and slightly decreased amplitude of a-wave and b-wave at 3 months postoperative; optical coherence tomography presented disruption of the inner segment/outer segment line at the onset of SMH but recovered completely at 3 months postoperative.


CONCLUSIONS
Subretinal tenecteplase was found to have sufficient hemolytic function and no retinal toxicity and could represent a feasible treatment option for the management of SMH.
