===Hyperbaric oxygen therapy===

[[Hyperbaric oxygen therapy]] (HBOT) is the administration of 100% oxygen at pressures greater than one-atmosphere absolute pressure (1 ATA) for a therapeutic purpose. HBOT can have several side effects, including the long-term development of cataracts. This is rare and generally associated with multiple HBOT exposures over a long period. As it does not usually become symptomatic during HBOT, it may often go unrecognised and is probably under-reported. Evidence is emerging that lifetime dosage of oxygen may be a precipitating factor in the development of age-related cataracts. Nuclear cataracts have been hypothesized to be the end stage of the far better known phenomenon of [[Hyperoxic myopia|hyperbaric myopic shift]].<ref name="Bennett and Cooper 2022" >{{cite journal |url=https://www.ncbi.nlm.nih.gov/books/NBK470454/ |website=www.ncbi.nlm.nih.gov |publisher=StatPearls Publishing LLC. |title=Hyperbaric Cataracts |first1=Michael H.|last1=Bennett |first2=Jeffrey S. |last2=Cooper |date=10 August 2022 |pmid=29261974 |access-date=27 February 2023 }}</ref>
