Summary
Hyperbaric oxygen (HBO) therapy significantly improved temporal visual field (TVF) defects after macular hole surgery. Patients receiving HBO showed remarkable TVF recovery, unlike the control group, highlighting HBO
Area of Science:
- Ophthalmology
- Neurosurgery
- Hyperbaric Medicine
Background:
- Macular hole (MH) surgery can lead to serious complications, including temporal visual field (TVF) defects.
- Understanding the efficacy of novel treatments for post-surgical visual field deficits is crucial for patient outcomes.
Observation:
- A cohort of 19 patients with post-vitrectomy TVF defects after MH surgery was studied.
- Seven patients received hyperbaric oxygen (HBO) therapy, while five served as a control group.
- Visual fields were assessed using kinetic perimetry, comparing post-treatment results to a 100% preoperative baseline.
Findings:
- Patients treated with HBO therapy demonstrated remarkable recovery of TVF defects.
- The average visual field area recovered to 81.7% after 3 days and 91.6% after months of HBO therapy.
- In contrast, TVF defects persisted in all patients who did not receive HBO therapy.
Implications:
- HBO therapy appears to be a beneficial treatment for TVF defects following macular hole surgery.
- The findings suggest that HBO may activate retinal cells and improve visual field function, potentially by addressing chorioretinal circulation disturbances.
- This study supports the use of HBO as an adjunctive therapy to mitigate visual field complications after MH surgery.
