| Abstract;Generally, unilateral occlusion induces a state of phoria in the occluded eye. This phenomenon is supposed to be related to the physiological resting position. We measured the cyclodeviation around the anteroposterior axis following 2 hours of unilateral occlusion in 35 persons. The series comprised 8 healthy volunteers and 27 patients of idiopathic or decompensated superior oblique palsy. The amount of cyclodeviation was measured using a scanning laser ophthalmoscope (SLO) before and after occlusion. Excyclodeviation developed in 14 patients (52%) of superior oblique palsy and in 5 healthy persons (63%). The amount of cyclodeviation averaged 2.01 degrees in superior oblique palsy and 0.65 degrees in healthy persons. Out of 27 patients with superior oblique palsy, 11 (41%) showed cyclodeviation greater than mean .+-.3*standard deviation in healthy persons. Average value of induced cyclodeviation was greater in superior oblique palsy than in healthy persons. The cycloposition in the resting position showed no definite direction in either group.
