The etiology of cribra orbitalia is obscure; however, a recent study has proposed that this anatomical variation is of a vascular nature. This study assessed the relationship between cribra orbitalia and vascular variation by determining the presence of meningo‐orbital foramina and cribra orbitalia. Of the 150 human orbits in this study, cribra orbitalia was found in 35:150 (23.3%) with 32:35 (91.4%) having a concurrent finding of the meningo‐orbital foramen. Further, 3:76 (2.0%) orbits with cribra orbitalia had an absence of the meningo‐orbital foramen. A Fisher's exact test was performed to determine the statistical significance and found that the two anatomical variants are dependent (p=0.0002). This study demonstrates a predisposition for cribra orbitalia in the presence of a meningo‐orbital foramen and provides further evidence of the vascular nature of cribra orbitalia. Clinically, a surgeon should be aware of vascular anastomoses in individuals with cribra orbitalia.
