dc.description.abstract BACKGROUND: Some patients undergoing hyperbaric oxygen therapy have subjectively reported a decrease is vision during treatment. The purpose of this study was to determine the incidence and magnitude of refractive changes in patients receiving hyperbaric oxygen therapy. METHODS: 43 consecutive patients (86 eyes) were examined prospectively while undergoing hyperbaric oxygen therapy. Best corrected vision, cycloplegic refraction, and slit lamp examination were performed at pre and post therapy visits. RESULTS: Overall, there was a mean change of -0.64 +/- 0.11 (dioptres +/- sem) (p less than 0.0001). Subgroup analysis demonstrated that in the 75 eyes that were phakic, there was a mean change of 0.74 +/- 0.12 D (p less than 0.0001). In the 11 eyes that were pseudophakic, there was a mean change of 0.03 +/- 0.05 D (p = 0.66). CONCLUSIONS: Hyperbaric oxygen therapy causes a significant myopic shift, exclusively in phakic eyes, suggesting a lenticular etiology of refractive change. This study provides harder numbers on the predictability of the ocular effects, which hyperbaric patients commonly encounter. Reversibility of these changes will be discussed in this presentation. hyperbaric oxygen, myopia, phakia, complication en_US
