What Researchers Did
Researchers presented a case report of a patient who developed scleral necrosis after beta-radiation for pterygium and was subsequently treated with hyperbaric oxygen therapy.
What They Found
A patient developed scleral necrosis 25 days after receiving 3000 cGy of strontium 90 in 3 weekly doses following pterygiectomy. After a failed conjunctival graft, the patient underwent 14 sessions of hyperbaric oxygen therapy, which led to scleral revascularization and near-normal thickness.
What This Means for Canadian Patients
Canadian patients experiencing scleral necrosis as a complication of beta-radiation for pterygium might benefit from hyperbaric oxygen therapy. This treatment could potentially help revascularize the sclera and prevent severe outcomes like globe perforation or vision loss.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor does it involve Canadian researchers or patients.
Study Limitations
A significant limitation of this study is its design as a single case report, which limits the generalizability of its findings.
