Situs Inversus of the Retinal Vessels
Photographers: First set: Brice Critser, CRA; Second Set: Carol Chan, CRA
Situs inversus of the retinal vessels is a rare developmental anomaly that has no visual significance. As noted in the photos below, the central retinal vessels emerge from the nasal aspect of the optic nerve (rather than temporal) and course nasally before turning temporally. Situs inversus can be seen in association with tilted disc syndrome, but is most often seen in otherwise normal, healthy eyes as an incidental finding.
