Two males (A) and (B) presented 6 days and few hours, respectively, after symptom onset with the clinical features typical of CRAO, including sudden severe deterioration of vision to counting fingers and a cherry-red spot in the left and right fovea, respectively. While A had been on recent treatment for hypertension and hyperlipidemia, B had no significant medical history. Both patients underwent surgery, A, 9 days, and B, &lt;15 h after symptom onset. Surgery involved a vitrectomy, lowering of intraocular pressure (&lt;3 mmHg), and gradual increase of arterial pressure to 165\/100 mmHg (through the slow injection of intravenous adrenaline). Intraoperatively, this resulted in immediate perfusion and visible dilation of the blood-filled central retinal artery (CRA) and retinal arteriolar network and dilatation of the central retinal vein. The final vision settled to 6\/60 in A and 6\/36+1 in B. Although preoperative macular infarction persisted in both eyes as demonstrated by optical coherence tomography angiography, both patients claim a convincing subjective visual benefit. The procedure appeared to have positively changed the natural history of the disease in both eyes. Vitrectomy with the manipulation of intraocular and arterial pressures significantly increases ocular perfusion along the entire CRA, which can dislodge CRA thrombo-emboli and has the potential to restore retinal perfusion and improve visual outcome if undertaken before irreversible retina damage. This is a relatively straightforward technique and should join the list of surgical techniques for treating CRAO.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/tjo.tjo_51_20","type":"journal-article","created":{"date-parts":[[2020,10,19]],"date-time":"2020-10-19T00:35:36Z","timestamp":1603067736000},"page":"305-311","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Vitrectomy and manipulation of intraocular and arterial pressures for the treatment of nonarteritic central retinal artery occlusion"],"prefix":"10.4103","volume":"11","author":[{"given":"Ogugua Ndubuisi","family":"Okonkwo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adekunle Olubola","family":"Hassan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toyin","family":"Akanbi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor Chukwuebuka","family":"Umeh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oladapo Oluwadamilola","family":"Ogunbekun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-16-20240830","doi-asserted-by":"crossref","first-page":"324","DOI":"10.1136\/emj.17.5.324","article-title":"Acute occlusion of the retinal arteries: Current concepts and recent advances in diagnosis and management","volume":"17","author":"Beatty","year":"2000","journal-title":"J Accid Emerg Med"},{"key":"R2-16-20240830","doi-asserted-by":"crossref","first-page":"376","DOI":"10.1016\/j.ajo.2005.03.038","article-title":"Central retinal artery occlusion: Visual outcome","volume":"140","author":"Hayreh","year":"2005","journal-title":"Am J Ophthalmol"},{"key":"R3-16-20240830","doi-asserted-by":"crossref","first-page":"2029","DOI":"10.1016\/S0161-6420(95)30758-0","article-title":"Efficacy of anterior chamber paracentesis and Carbogen in treating acute nonarteritic central retinal artery occlusion","volume":"102","author":"Atebara","year":"1995","journal-title":"Ophthalmology"},{"key":"R4-16-20240830","doi-asserted-by":"crossref","first-page":"723","DOI":"10.1016\/S0014-4835(03)00214-8","article-title":"Central retinal artery occlusion.
