Hyperbaric oxygen and corneal incision healing

F G Anderson, W W Bay, W P Fife

    Undersea Biomedical Research
    |December 1, 1978
    PubMed
    Summary

    Daily hyperbaric oxygen (HBO) therapy did not significantly alter corneal incision healing in dogs. Comparable healing occurred in both HBO-exposed and control groups, with a slight suggestion of faster opacity clearing in the HBO group.

    Area of Science:

    • Ophthalmology
    • Wound Healing
    • Hyperbaric Medicine

    Background:

    • Corneal incisions require effective healing for visual recovery.
    • Hyperbaric oxygen therapy (HBOT) is used for various medical conditions.
    • The effect of HBOT on corneal wound healing is not fully understood.

    Purpose of the Study:

    • To investigate the impact of daily hyperbaric oxygen exposure on corneal incision healing in a canine model.
    • To compare the healing process with natural healing without HBOT.

    Main Methods:

    • Canine corneal incisions were created.
    • Twenty corneas were exposed to daily 90-minute sessions of 60% oxygen at 2 ATA (absolute atmospheres).
    • Twenty corneas served as controls, healing naturally.
    • Corneas were analyzed via gross observation and light microscopy at intervals from 5 to 56 days post-incision.

    Main Results:

    • Uncomplicated and comparable healing of corneal incisions was observed in both HBOT-exposed and control groups.
    • A trend suggested that superficial central opacity clearing occurred more rapidly in the HBOT group.
    • No significant adverse effects on healing were noted with HBOT.

    Conclusions:

    • Daily hyperbaric oxygen exposure at 2 ATA does not impede corneal incision healing in dogs.
    • HBOT may offer a slight benefit in accelerating the resolution of incisional opacity.
    • Further research could explore optimal HBOT parameters for corneal wound management.
