Uncommon retinal vascular anomalies.

چکیده
STANDARD works on the anatomy of retinal blood vessels (Leber, 1915; Wolff, 1954; Michaelson, 1954; Ballantyne and Michaelson, 1962) state that the four principal divisions of the central retinal artery and vein proceed to and from their respective quadrants, pursuing a sinuous course and branching dichotomously. This paper describes three types of uncommon retinal vascular anomaly with a unilateral incidence occurring in normally functioning eyes.
