Hyperbaric oxygen therapy (HBOT) has emerged as a potential treatment to enhance retinal oxygenation and salvage ischemic tissue, though its efficacy and safety remain debated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0317167125103648_as2\">\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Databases were searched through November 2024 for studies comparing HBOT with control in RAO patients. Risk of bias was assessed using the Newcastle-Ottawa Scale. Meta-analyses evaluated visual acuity (VA), best-corrected visual acuity (BCVA) and adverse events (AEs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0317167125103648_as3\">\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Nine studies with 499 patients (286 HBOT, 213 non-HBOT) met the inclusion criteria. HBOT was associated with improved BCVA (MD: \u20130.63, 95% CI: [\u20131.14, \u20130.12],\n                      <jats:italic>p<\/jats:italic>\n                      = 0.01) after sensitivity analysis. No significant differences were observed in uncorrected VA or lines of improvement. AEs included seizures (1.47%), ear barotrauma (1.65%) and epistaxis (0.83%) in the HBOT group. Notably, HBOT was associated with lower rates of neovascular glaucoma (7.89% vs. 15.79%) and stroke (4.3% vs. 16.6%) compared to controls.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0317167125103648_as4\">\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>HBOT demonstrates potential for improved visual outcomes in RAO patients, particularly BCVA, with a generally favorable safety profile. However, heterogeneity among studies and limited sample sizes highlight the need for robust prospective trials to clarify its role in RAO management.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1017\/cjn.2025.10364","type":"journal-article","created":{"date-parts":[[2025,7,31]],"date-time":"2025-07-31T06:55:51Z","timestamp":1753944951000},"page":"663-672","source":"Crossref","is-referenced-by-count":3,"title":["Efficacy and Safety of Hyperbaric Oxygen Therapy for Retinal Artery Occlusion: A Systematic Review and Meta-Analysis"],"prefix":"10.1017","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1125-2946","authenticated-orcid":false,"given":"Mohamed","family":"Elfil","sequence":"first","affiliation":[{"name":"University of Miami\/Jackson Health System"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanin","family":"Sabet","sequence":"additional","affiliation":[{"name":"South Valley University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5101-5972","authenticated-orcid":false,"given":"Abdallah","family":"Abbas","sequence":"additional","affiliation":[{"name":"Al-Azhar University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7633-5961","authenticated-orcid":false,"given":"Ahmed","family":"Bayoumi","sequence":"additional","affiliation":[{"name":"McGovern Medical School at UTHealth Houston"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hazem S.","family":"Ghaith","sequence":"additional","affiliation":[{"name":"Al-Azhar University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed Hesham","family":"Ghoneem","sequence":"additional","affiliation":[{"name":"Alexandria University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amr","family":"Shaarawy","sequence":"additional","affiliation":[{"name":"Alexandria Ophthalmology Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monsef Ibrahim","family":"Kharboush","sequence":"additional","affiliation":[{"name":"Alexandria University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4884-1891","authenticated-orcid":false,"given":"Mohammad","family":"Aladawi","sequence":"additional","affiliation":[{"name":"University of Alabama"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zaid","family":"Najdawi","sequence":"additional","affiliation":[{"name":"University of Nebraska Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaitanya","family":"Medicherla","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel A.","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly A.","family":"Hutcheson","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Elefant","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gurmeen","family":"Kaur","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chirag D.","family":"Gandhi","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fawaz","family":"Al-Mufti","sequence":"additional","affiliation":[{"name":"Westchester Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,7,31]]},"reference":[{"key":"S0317167125103648_ref21","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-021-10838-6"},{"key":"S0317167125103648_ref12","doi-asserted-by":"publisher","DOI":"10.37845\/ret.vit.2024.33.18"},{"key":"S0317167125103648_ref10","doi-asserted-by":"publisher","DOI":"10.22462\/01.03.2020.7"},{"key":"S0317167125103648_ref3","doi-asserted-by":"publisher","DOI":"10.1136\/bjo-2023-323972"},{"key":"S0317167125103648_ref13","doi-asserted-by":"publisher","DOI":"10.22462\/07.08.2021.7"},{"key":"S0317167125103648_ref23","doi-asserted-by":"publisher","DOI":"10.22462\/10.12.2020.14"},{"key":"S0317167125103648_ref8","doi-asserted-by":"publisher","DOI":"10.1186\/s12874-024-02356-6"},{"key":"S0317167125103648_ref11","doi-asserted-by":"publisher","DOI":"10.1097\/IAE.0000000000004253"},{"key":"S0317167125103648_ref7","unstructured":"7.
