Hyperbaric oxygen therapy (HBOT) can be a useful primary or adjunctive therapy for a variety of medical disorders, many of which involve the eye. This chapter will review the effects of oxygen on eye, the literature describing use of HBOT for a variety of conditions and the potential complications of HBOT affecting the eye. The authors recommend the following as ocular indications for HBOT: decompression sickness or arterial gas embolism (AGE) with visual signs or symptoms, central retinal artery occlusion, ocular and periocular gas gangrene, cerebro-rhino-orbital mucor mycosis, periocular necrotizing fasciitis, carbonmonoxide poisoning with visual sequelae, radiation optic neuropathy, radiation or mitomycin C-induced scleral necrosis, and periorbital reconstructive surgery. Other ocular disorders that may benefit from HBOT include selected cases of ischemic optic neuropathy, ischemic central retinal vein occlusion, branch retinalartery occlusion with central vision loss, ischemic branch retinal vein occlusion, cystoid macular edema associated with retinal venous occlusion, post-surgical inflammation, or intrinsic inflammatory disorders, periocular brown recluse spider envenomation, ocular quinine toxicity, Purtscher’s retinopathy, radiation retinopathy, anterior segment ischemia, retinal detachment in sickle cell disease, refractory actinomycoticlacrimal canaliculitis, pyoderma gangrenosum of the orbit, and refractory pseudomonas keratitis. Visual function should be monitored as clinically indicated before, during, and after therapy when HBOT is undertaken to treat vision loss. Visual acuity alone is not an adequate measure of visual function to monitor the efficacy of HBOT in this setting. Because some ocular disorders require rapid administration of HBOT to restore vision, patients with acute vision loss should be considered emergent when they present and treatment with supplemental oxygen should be initiated.

PURPOSE: To examine ocular lens parameters and structural changes to elucidate mechanisms underlying the myopic shift and cataract-related changes that occur in some patients during hyperbaric oxygen (HBO) therapy. METHODS: Scheimpflug images (Nidek EAS-1000) of the crystalline lens, measurements of scattered light, objective refraction, keratometry, tonometry, and axial length of the eye were obtained after the first day of HBO therapy and repeated when patients had completed 19 days of the tre...

Background Central retinal artery occlusion (CRAO) is an ocular emergency and most of the cases present with painless sudden persistent loss of vision in the range of counting fingers to perception of light. The presentation of CRAO is associated with a variety of medical conditions. We report a rare case of CRAO associated with persistent truncus arteriosus (PTA) and single atrium in a female patient.

Abstract Central retinal artery occlusion (CRAO) is an uncommon eye disorder, but one that typically produces severe and irreversible vision loss in the affected eye. The retina has a dual blood supply, with the retinal circulation supplying the inner layers and the choroidal circulation supplying the outer layers. In CRAO, vision loss results from cell death in the inner retinal layers despite relative sparing of the outer layers. If supplemental oxygen is provided, however, oxygen from the cho...

Purpose To compare hyperbaric oxygen treatment combined with hemodilution with hemodilution only in central retinal artery obstruction. Design Retrospective, nonrandomized case series. Methods We reviewed records of all our patients diagnosed with central retinal artery obstruction between 1997 and 2010. In these patients, hyperbaric oxygen and hemodilution therapy had been administered routinely (oxygen group). Where hyperbaric oxygenation could not be performed, patients were underwent hemodil...

PURPOSE: To investigate the effect of hyperbaric oxygen (HBO) chamber treatment in mouse models of retinal ischemia. METHODS: Unilateral central retinal artery occlusion (CRAO) or optic nerve crush (ONC) was induced in 50 mice each, of which 30 were treated with 100% oxygen at 2 atm for 90 minutes immediately after injury and then daily for up to 14 days. Mice were euthanatized on days 1, 3, and 21 for histologic analysis, apoptosis assay, and quantitative real-time polymerase chain reaction tes...

METHODS: We describe a case series of 11 patients with retinal artery occlusion treated with hyperbaric oxygen therapy (HBOT) at Intermountain Dixie Regional Medical Center between 2005 and 2009. We then combined data from our case series with data from two other case series to report on a combined total of 51 patients. RESULTS: Eight of our 11 patients achieved improved visual acuity. Analysis of the combined case series showed that 74 % of patients treated with HBOT had improvement in visual a...
