ptosis, headache, nausea, vomiting, dizziness, tinnitus, and urinary urgency. At their initial ophthalmology evaluation, 6 patients had no light perception in the affected eye. Of these cases, 2 patients had care by ophthalmologists that included a vitrectomy in 1 case; neither had visual improvement by the final follow-up. The only case of vision recovery involved a patient whose visual acuity had declined to 20/200 after PRP injection. 5 This patient was evaluated and treated by an ophthalmologist within 3 hours of symptom onset. She had a full recovery of visual acuity at 3 months but with residual deficits on eye examination.Limitations of this study include a general lack of details on PRP injection technique in all cases. It is unknown whether soft tissue fillers were mixed with PRP in any of the cases. Furthermore, treatment and follow-up were limited in several cases.This systematic review shows that vision loss is a potential rare but devastating complication of PRP injections. Highly concentrated platelets may act as a procoagulant when injected intravascularly leading to occlusion and ischemia. Given this risk, physicians must use similar precautions when injecting PRP as when injecting soft tissue fillers. The glabella and forehead appear to be high-risk areas, but injection locations as distant as TMJ and nasolabial fold are not risk-free. Vision loss after PRP can be complete and irreversible. However, early evaluation and treatment may be helpful in cases of partial vision loss.
