This 37YO female presented with recent vision loss in her right eye. She had a history of prior laser treatment elsewhere several years ago. Vision was 20/30 OD and 20/25 OS.
Red preretinal blood was seen in the inferotemporal right macula with partial PRP scarring. One month following a single Avastin injection, the devitalized preretinal blood was yellowing. Bilateral PRP is planned.
Learning Points:
PRP has been around since the 1960s and still remains the mainstay for treating proliferative disease. Often considered a “one and done”, patients can still develop break-through hemorrhage or progressive neovascular growth and traction.
Intravitreal anti-VEGF injections are often helpful, but some will require vitrectomy.
In our patient’s case, the new preretinal blood was most likely due to her having been incompletely treated rather than a PRP failure.
