PRDM13 is a transcription factor known to play a critical role in the specification of neurons across the central nervous system, and its expression is maintained into adulthood in a limited number of neuronal types, including neurons of the dorsomedial hypothalamus and retinal amacrine cells. Dysregulation of PRDM13 has been associated with three inherited human maculopathies - North Carolina macular dystrophy (NCMD), progressive bifocal chorioretinal atrophy (PBCRA), and congenital posterior polar chorioretinal hypoplasia (CPPCRH) - indicating that PRDM13 may also play a role in development and maintenance of non-amacrine retinal cell types. Herein, we review the known roles of PRDM13 across the developing central nervous system to provide a comprehensive understanding of PRDM13's general and tissue-specific functions, as well as how PRDM13 dysregulation may lead to improper macular development and disease.

Higher EPR prevalence was associated (multivariable analysis) with higher prevalence of central retinal vessel trunk dragging (CRVTD) (odds ratio [OR] = 8.81; 95% CI, 3.02-25.7; P < 0.001) and longer axial length (OR = 2.97; 95% CI, 2.27-3.89; P < 0.001; Nagelkerke R2 = 0.55), or alternatively with longer fovea-optic disc center distance (OR = 2.79; 95% CI, 1.55-5.03; P < 0.001). In a nonlinear manner, EPR prevalence increased steeply beyond an axial length of 25.5 mm and a fovea-disc center distance of 5.5 mm. These relationships were complemented by univariate associations between EPR prevalence and temporal retinal vessel straightening, smaller angle kappa, higher myopic macular degeneration stage and prevalence, and larger parapapillary beta zone and gamma zone.</p><p><strong>Conclusions: </strong>EPR was a common feature in eyes with severe/high axial myopia and was mainly associated with CRVTD and longer axial length or fovea-disc center distance. As a hypothesis, EPR, contrary to myopic foveoschisis, may be due to a stretching of the temporal large retinal vessels in highly myopic eyes, related to the fovea-disc distance elongation.</p>","PeriodicalId":14620,"journal":{"name":"Investigative ophthalmology & visual science","volume":"67 12","pages":"7"},"PeriodicalIF":5.5,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13648563/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149109673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
