Optic Nerve Injury, Vitreous Hemorrhage, and Rhegmatogenous Retinal Detachment Following Long Needle Peribulbar Anesthesia: A Case Report and Review of the Literature.

Rhegmatogenous retinal detachment (RRD) following retrobulbar or peribulbar anesthetic injection is a rare but serious complication that often results in poor visual outcomes. Thus, extreme caution should be exercised while administering local ocular anesthesia due to the potential complications arising from local orbital anesthesia. These complications may occur locally or systemically and may arise immediately or be delayed. This case report is on a female patient who sustained optic nerve injury and RRD due to a peribulbar block administered in the setting of cataract extraction and, subsequently, experienced retinal detachment and vitreous hemorrhage at another hospital before being referred to our hospital. The retina was repaired with pars plana vitrectomy, 360 endolaser of the peripheral retina and around tears, and gas injection, achieving stable visual outcomes.
