Though long a subject of controversy, the question of whether or not there is a significant relationship between the side of greater choking of the optic disk and the side of the tumor remains undecided. This question has considerable theoretical importance. It bears on the etiology of choked disk, and on the disturbances produced by expanding intracranial lesions.
Martin1 studied 55 cases of intracranial tumor with unequal choked disk, and found that in the majority (71 per cent) the greater choking was on the same side as the tumor. Paton2 studied 48 cases and found that in only 52 per cent was the greater choking on the same side as the tumor. He observed that tumors of the temporal lobe tended to give homolaterally greater choking more often than did tumors in other positions. Gunn,3 analyzing Martin's data, had earlier made a similar observation.
