The Osteo-odonto-keratoprosthesis to restore vision after severe dog bite injury

J Curr Ophthalmol. 2018 Sep 29;31(2):238-241. doi: 10.1016/j.joco.2018.09.006. eCollection 2019 Jun.

Abstract

Purpose: To present our experience in Osteo-odonto-keratoprosthesis (OOKP) as the only option to restore vision after severe ocular dog bite injuries.

Methods: We describe our results in OOKP performed in two patients with previous severe dog bite facial injuries that required exenteration of one eye and facial reconstruction.

Results: Both cases achieved initially successful anatomical and visual outcome; however, one case suffered retinal detachment after one year. Buccal mucosa (BM) ulcerations and tilted lamina were present as a result of extraocular muscles loss, and both were difficult to treat.

Conclusion: OOKP has the capability to restore vision in the most challenging cases of ocular trauma; however, refractory BM ulcerations and tilted lamina could be expected as a result of an ischemic ocular surface and orbital pulleys loss.

Keywords: Dog bite ocular injury; Keratoprosthesis; Osteo-odonto-keratoprosthesis.
