Ocular perforation during retrobulbar and peribulbar injections

Abstract

Background and objective: To determine the ocular perforations during retrobulbar and peribulbar injections.

Patients and methods: Twenty-five ocular perforations between 1976 and 1993 occurred after 13 retrobulbar and 12 peribulbar injections. Eighteen patients (72%) were women. Eighteen eyes were myopic (72%). Risk factors included high myopia in 11 cases (44%), use of Atkinson gaze in 21 cases (84%) and a sharp injection needle.

Results: Deep position of the posterior pole was common. Perforation signs comprised vitreous hemorrhage in 25 eyes (100%), subretinal hemorrhage in 19 eyes (76%), retinal breaks along the inferior vascular arcade in 19 eyes (76%), and retinal detachment in 14 eyes (56%). Proliferative vitreoretinopathy developed in 11 eyes (44%).

Conclusion: Retinal detachment strongly correlated to poor visual outcome.
