Hyperbaric oxygen therapy for the treatment of radiation-induced macular ischemia.
OBJECTIVE
To report a case of radiation-induced macular ischemia where vision and macular perfusion improved after hyperbaric oxygen (HBO) therapy.


METHODS
A 62-year-old male patient developed radiation-induced macular ischemia after he was treated with radiation for brain glioma. The patient presented with best spectacle-corrected visual acuity (BSCVA) acuity of 20/400 in his right eye. Optical coherence tomography (OCT) showed central macular thickness of 468 mum. The patient received focal laser, intravitreal triamcinolone, and HBO therapy.


RESULTS
The patient's vision improved from 20/400 to 20/100 after focal laser and intravitreal triamcinolone. His central macular thickness improved from 468 mum to 132 mum. After receiving HBO therapy, his VA improved to 20/50 and fluorescein angiography showed improvement in macular perfusion.


CONCLUSIONS
HBO therapy improves macular perfusion in patients with radiation-induced macular ischemia.
