Abstract Hyperbaric oxygen treatment is becoming increasingly popular in the treatment of soft tissue injuries and degenerative conditions. Previous studies have reported the development of nuclear and posterior sub-capsular cataract and reversible myopic changes arising from hyperbaric oxygen treatment. A 64-year-old white male attended for review as he had noticed a decrease in his distance vision since his examination six months previously. He reported having undergone a series of 17 hyperbaric chamber treatments over the preceding 2 months for the treatment of a leg ulcer. General history was unremarkable with no diabetes and controlled blood pressure. His distance visual acuity corrected to 20/20= OD and 20/20 OS, however, he had undergone a myopic shift of -1.25 OU and -1.75 OS since his last examination six months previously. Slit lamp examination revealed slight posterior subcapsular changes that were not present at the previous visit. Early nuclear lenticular changes appeared unchanged. IOPs were unchanged at OD 14 mmHg and OS 16 mmHg. Ophthalmoscopy was also unremarkable. This case report also aims to document the recovery of the myopic shift and any changes in corneal shape, axial length and anterior chamber depth. Clinicians can potentially expect to see an increase in the number of patients who have undergone this form of rehabilitation and need to be aware of the clinical implications.
