Inadvertent perforation of the globe during regional anaesthesia

Purpose: This retrospective study was undertaken to review the clinical signs and management of patients with perforating eye injuries associated with regional anaesthesia for ophthalmic surgery.
Methods: Fifteen consecutive patients presenting with inadvertent perforation of the globe were evaluated. Eleven required vitreoretinal surgery. The indications were retinal detachment (six eyes), vitreous haemorrhage (four) and an epiretinal membrane (one eye).
Results: Those eyes with retinal detachments generally had a poor functional outcome in spite of the retinae being attached in five of the six eyes. The operative findings of those eyes with vitreous haemorrhage but attached retina demonstrated varying retinal tear configurations.
Conclusions: Eyes with perforating injuries following intraorbital anaesthesia are at risk of developing a retinal detachment. In those eyes presenting with dense vitreous but attached retina, consideration of vitrectomy and laser photocoagulation is advised.
