Black/African American MI-SIGHT participants had larger cup-to-disc ratios and cup volumes, while White MI-SIGHT participants had smaller ONH values, except for rim area and rim volume, compared to Topcon participants (all P<0.001). The MI-SIGHT cohort's RNFL color codes did not follow the expected distribution (P<0.05); more MI-SIGHT RNFL quadrant measurements were assigned as white (10.6% and 6.3% MI-SIGHT v 5% Topcon) and red codes (2.2% and 1.8% MI-SIGHT v <1% Topcon) than expected in the superior and inferior quadrants respectively.</p><p><strong>Conclusion: </strong>OCT normative databases should accurately reflect diverse populations to avoid misclassification by RNFL thickness color codes.

A 74-year-old male presented to the emergency department with altered mental status due to acute-onset hyponatremia. Six days after admission, the patient noticed painful loss of vision in his right eye and an ipsilateral headache lasting 10-15 minutes. Upon follow-up with his primary care physician several days later, a fixed, dilated right pupil was noted. On ophthalmologic evaluation in the ER the next day, the patient was found to have markedly elevated intraocular pressure (IOP) at 47 mm Hg in the right eye. He started topical brimonidine, dorzolamide 2%/timolol 0.5%, and latanoprost, and underwent phacoemulsification with placement of a posterior chamber intraocular lens (PCIOL) in the right eye. Several mechanisms of polydipsia induced AACC are proposed including choroidal expansion, increased sympathetic α-adrenergic tone, or differences in osmotic potential forces.</p>","PeriodicalId":15938,"journal":{"name":"Journal of Glaucoma","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143059222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
