Treatment of tissue necrosis with hyperbaric oxygen therapy in a patient with pseudomonas endophthalmitis and orbital cellulitis: a case report.

Purpose: This report presents the treatment of tissue necrosis after evisceration with hyperbaric oxygen therapy (HBOT) in a patient with pseudomonas endophthalmitis and orbital cellulitis. Methods: A 49-year-old woman was admitted to our clinic with severe pain and vision loss after cataract surgery 3 days before, and pars plana vitrectomy 2 days before for endophthalmitis, in another hospital. Examination findings included limbal perforation, orbital cellulitis findings, and loss of light perception in the right eye. The patient, who received evisceration surgery and antibiotic treatment, showed loosening of the conjunctival sutures and necrosis in the conjunctiva, tenon, and sclera on the 9th postoperative day. The necrotic tissues were surgically debrided and the patient was referred to HBOT. Results: With HBOT and antibiotherapy, signs of inflammation regressed, healing on the conjunctival surface was accelerated, and prosthesis was suitable for use. Conclusions: Hyperbaric oxygen therapy is a treatment method that plays an active role in the healing of necrotic tissues by increasing the oxygenation and vascularization of the tissue.
