Congenital retinal macrovessels
G. C. Brown, L. A. Donoso, L. E. Magargal, R. E. Goldberg and L. K. Sarin
The clinical and fluorescein angiographic features of seven patients with
unilateral, large retinal vessels supplying or draining the macular region,
both inferior and superior to the horizontal raphe, are described. All
patients had good vision, although two patients also had a concomitant
foveolar cyst in the involved eye. Four of the seven eyes had small
perifoveolar arteriovenous communications, while three eyes did not. Four
eyes also showed abnormal areas of retinal capillary nonperfusion. In
addition, delayed drainage of dye from the enlarged vessels was a commonly
encountered feature. It is suggested that these congenital anomalies be
referred to as retinal macrovessels.
