Introduction: There has been a growing interest in hyperbaric oxygen therapy (HBOT) in recent years across multiple disciplines. In the field of ophthalmology, the implications of increased HBOT use may include expanded applications in treating ocular vascular pathologies as well as a greater incidence of HBOT-induced visual complications. Areas covered: The authors review recent studies on HBOT usage in the treatment of ocular conditions. In addition to providing updates on the ophthalmic indications of HBOT, adverse visual effects of HBOT are also investigated. Expert opinion: Further evidence substantiating HBOT as an effective treatment modality for ocular vascular pathologies, such as central retinal artery occlusion and diabetic retinopathy, have been published in recent years. With the identification of more prognostic factors, increased success in HBOT has been reported. However, studies also show that adverse ocular effects associated with hyperbaric oxygen exposure include myopia and cataracts. It is important to recognize the risks of iatrogenic changes in visual acuity when considering patients for HBOT.
