Abstract:
BACKGROUND:Cilioretinal arteries (CAs) represent enlargements of microscopic and early established collaterals formed via vasculogenesis between choroidal and retinal circulations. We aimed to investigate whether genetic tendency to thrombosis due to well-known gene polymorphisms may induce CA vasculogenesis in embryonic life. METHODS:We assessed plasminogen activator inhibitor-1 (PAI-1) 4G/5G, methylenetetrahydrofolatereductase (MTHFR), FACTOR V LEIDEN and PROTHROMBIN gene polymorphisms on 130 patients [82/48 females/males; Median age: 57 (18-84) with visible CAs and 100 (64/36: female/male; Median age: 55 (19-90)] without visible CAs. RESULTS:Using multiple logistic regression models, we found PAI-1 4G/5G; MTHFR (C677T and A1298C) polymorphisms to have significant effects on the probability of visible CAs, that having at least one 5G allele would increase the odds of having visible cilioretinal artery by 98.4% [Odds ratio: 1984 (95% CI: 1.320-3.000, p = 0.001)], and having at least one MTHFR C677T or A1298C allele would decrease the odds of having visible CAs by approximately 38% (OR = 0.618, 95% CI: 0.394-0.961, p = 0.035) or 44% (OR = 0.558, 95% CI: 0.354-0.871, p = 0.011), respectively. CONCLUSIONS:This is the first study to test the existence of significant association between presence of enlarged and visible CAs and genetic factors predisposing to thrombosis, according to the literature. Here we suggest that not only the lack of genetic predisposition to thrombosis by MTHFR gene polymorphisms, but also the PAI-1 5G allele might promote vasculogenesis of CAs.
