Post periorbital carboxytherapy orbital emphysema: a case report.

Periorbital carboxytherapy is used as one of the non-surgical facial rejuvenation methods in recent years. In this modality, the sterile carbon dioxide is injected into the subcutaneous space, assuming that to improve blood supply and repair of the injection site. Here, we report a 24- year-old woman who presented with acute bilateral orbital emphysema starting one day after cosmetic periorbital carboxytherapy. On physical examination, bilateral non-tender, non-erythematous swelling of both upper and lower lids was noted with crepitus on palpation. Uncorrected visual acuity (UCVA) of the patient in both eyes was 10/10 and RAPD was negative. The orbital computed tomography (CT) scan of the patient confirmed bilateral preseptal emphysema extending into orbital space through the orbital septum. Oral prednisolone 50 mg per day was prescribed, and the patient was observed closely. Gradually, periorbital pain and swelling subsided, and the symptoms resolved within one week.
