“…However, a few reports in the literature have described the presence of ampullae of the vortex veins at the macular region associated with various diseases, such as congenital glaucoma in a patient with trisomy 13 syndrome, diabetes mellitus, oculocutaneous albinism, and focal choroidal excavation. 7 – 10 Additionally, PVVs have been found to be more common in eyes with high myopia. 11 – 15 In our study, we made the significant observation that vortex veins can also be detected in the posterior pole of healthy eyes, specifically in emmetropic eyes, challenging the previous notion that ampullae of the vortex veins are primarily located at the equator.…”

“…Occasionally, anomalous vortex veins exits can be located at the posterior pole of the eyes, associated with various chorioretinal diseases. 7 – 10 Several cases of vortex vein exits located at the macular area have been reported in individuals with high myopia. 11 – 13 Moriyama et al identified posterior vortex veins (PVVs) in 11% highly myopic eyes using indocyanine green angiography (ICGA).…”

Purpose The purpose of this study was to investigate the incidence and characteristics of posterior vortex veins (PVVs) in healthy eyes and explore their relationship with age and refractive status. Methods This retrospective cross-sectional analysis encompassed 510 eyes from 255 consecutive healthy participants. Wide-field optical coherence tomography angiography (WF-OCTA) imaging was used to assess the presence of PVVs. Eyes were classified according to refractive status (emmetropia, low and moderate myopia, and high myopia) and age (minors and adults). The incidence and characteristics of eyes with PVVs were analyzed. Results Participants (mean age = 30.60 ± 21.12 years, 47.4% men) showed a mean refractive error of −2.83 ± 3.10 diopters (D; range = −12.00 to +0.75). PVVs were observed in 16.1% (82/510) of eyes. Of these, 39% (32/82) had PVVs in one eye and 61% (50/82) in both eyes. The mean number of PVVs per eye was 1.65 ± 1.05 (range = 1–6). PVVs are mainly around the optic disc (78%, 64/82) of eyes with PVVs and less in the macular area (6.1%, 5/82) or elsewhere (15.9%, 13/82). PVV incidence correlated with refractive status: 10.3% (22/213) in emmetropia, 16.6% (31/187) in low and moderate myopia, and 26.4% (29/110) in high myopia ( P = 0.001), but not with age. Refractive status was the key predictor of PVV occurrence (odds ratio [OR] = 1.45, 95% confidence interval [CI] = 1.02–2.06, P = 0.038). Conclusions This study confirms PVVs' presence in healthy eyes, highlighting their inherent existence and susceptibility to alterations due to refractive conditions. These findings enhance our understanding of the vortex vein system and its distribution within the eyes.
