Abstract
Laser scotometry is an accurate means of detecting dense blind spots. A small low-energy spot is guided across the fundus from nonseeing to seeing areas. Patient responses are recorded on fundus photographs, allowing direct correlation with fundus pathology. Accuracy to less than 1° is feasible. All typical optic nerve drusen tested with this technique had field defects. In cases of optic nerve pits, dense scotomas correlated with the shape of visible nerve fiber defects rather than with the shape of serous retinal detachments.
