  • Title: Quadrant sparing of the macula.
    Author: Ehlers N.
    Journal: Acta Ophthalmol (Copenh); 1975 Jun; 53(3):393-402. PubMed ID: 1174401.
    Abstract:
    Macular sparing is an indisputable clinical finding in cases of hemianopia. Several explanations have been given, some of which are not mutually exclusive. Eight cases, encountered in a study of more than 100 hemianopias, are presented, in which the sparing has the form of a quadrant, either upper or lower. The explanation in these cases seems to be the double vascular supply to the tip of the occipital pole. It is stressed, however, that macular sparing may have a different explanation in other cases.
