Imaging Features of a Retinal Detachment and Secondary Epiretinal Membrane Following Inadvertent Globe Penetration From Peribulbar Anesthesia.

Purpose: We present imaging features of retinal detachment (RD) and secondary epiretinal membrane in a case of an inadvertent globe penetration following preoperative peribulbar anesthesia. Methods: A 60-year-old woman was referred for a localized RD and epiretinal membrane following uneventful cataract surgery. Widefield fundus photography and optical coherence tomography were used to assess and record the pathology. The current literature was reviewed. Results: Full-thickness breaks were noted in the neurosensory retina extending into the scleral wall. Vertical tracks were noted in the inferotemporal quadrant of the eye. The patient underwent trans pars plana vitrectomy, membrane peel, and gas. Her 1-month postoperative visual acuity was 20/30. Conclusions: Globe penetration with RD is a rare but potentially sight-threatening complication of peribulbar anesthesia. Diagnosis can be challenging because of the infrequency of occurrence and delays in presentation. A high index of suspicion is key alongside consideration of other likely differentials.
