Retinal toxicity after accidental intravitreal injection of mepivacaine and adrenaline.

CASE REPORT: The case is presented of a 32 year-old male with no medical history of interest who suffered a traffic accident with mild traumatic brain injury. He had a left supraciliary incised and contused wound that extended to the left upper eyelid, with no loss of vision. After palpebral anaesthetic injection, there was a sudden visual acuity decrease in the left eye and hyposphagma located between I-III at 4mm from the limbus, with increased intraocular pressure. A whitish lesion with a central haemorrhagic focus was observed in the ocular fundus, corresponding to the area where the hyposphagma was located.

DISCUSSION: Anaesthetic injection during palpebral repair may be complicated by inadvertent penetration of the eyeball. Intravitreal mepivacaine and adrenaline could cause macular and retinal lesions.
