Summary
Hyperbaric oxygen therapy effectively treated scleral necrosis, a complication of beta-radiation for pterygia. This treatment helped the sclera recover and regain thickness after surgery.
Area of Science:
- Ophthalmology
- Radiation Oncology
Background:
- Beta-radiation is a common postoperative treatment to prevent pterygium recurrence.
- Scleral necrosis is a serious complication of radiotherapy, potentially causing globe perforation and vision loss.
Observation:
- A patient developed scleral necrosis 25 days post-pterygiectomy with beta-radiation (strontium 90).
- The patient underwent conjunctival grafting, which failed, before receiving hyperbaric oxygen therapy.
Findings:
- After 14 sessions of hyperbaric oxygen therapy, the patient's sclera showed revascularization.
- The scleral thickness returned to near normal levels.
Implications:
- Hyperbaric oxygen therapy shows promise as an effective treatment for acute scleral necrosis.
- This approach may help prevent severe complications following radiotherapy for pterygia.
