Retrobulbar abscess: rare complication after repair of an oroantral communication.

We present the case of a retrobulbar abscess that developed secondary to the repair of an oroantral communication. Orbital abscesses have been described in relation to odontogenic infections, facial injury, sinusitis, and after dental extractions but, to the best of our knowledge, none has been reported in these circumstances. Retrobulbar abscess is a rare complication, but early clinical and radiological diagnosis, and urgent decompression are vital because it comes with considerable risk of irreversible visual impairment.
