Summary

What Researchers Did

Researchers documented the case of a 58-year-old man who experienced vision changes, specifically a hypermetropic shift succeeding a myopic shift, during and after hyperbaric oxygen therapy.

What They Found

They found that after each of two HBO series, the patient's vision shifted first to myopia then to hypermetropia. The maximal refractive amplitude was 3.00 D in the right eye and 2.75 D in the left eye, with refraction stabilizing at +0.62 D and +0.50 D after 1.5 years.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

A significant limitation is that this study is a single case report, which limits the generalizability of its findings to a broader patient population.
