Hypermetropic refractive change after hyperbaric oxygen therapy

Middle-ear barotrauma after hyperbaric oxygen therapy.

BACKGROUND Middle-ear barotrauma (MEB) is one of the most common side effects of hyperbaric oxygen therapy (HBO2). The incidence of MEB has been shown to vary between treatment centers and patients. This study was aimed to determine which patients are at high risk of MEB. MATERIALS AND METHODS Prospective study including all the patients treated in a multiplace HBO2 chamber between January an...

Hypermetropia-succeeded myopia after hyperbaric oxygen therapy.

A 58-year-old man presented with a change in vision during hyperbaric oxygen (HBO) therapy. Subsequent follow-up visits showed a hypermetropic shift, which succeeded the myopic shift after each of two series of HBO treatments. The maximal refractive amplitude was 3.00 D (range -1.37 D to +1.62 D) in the right eye and 2.75 D (range -1.25 D to + 1.50 D) in the left eye. Refraction stabilized afte...

Hyperbaric oxygen therapy.

Hyperbaric oxygen therapy (HBOT) is emerging in veterinary medicine as an effective treatment or adjunct therapy for a variety of disorders in which improving oxygen delivery to tissues is a priority. The primary mechanisms of action of HBOT are (1) immediate hyperoxygenation of plasma and tissues and (2) decreased gas bubble (air embolus) size. With each hyperbaric 'dive,' secondary physiologi...
