Paradoxical movements of the eyelid and eyeball
Abstract:
Two cases of ptosis with paradoxical eye and lid movements have been reported. One of them was congenital, where there was narrowing of palpebral aperture on abduction and pseudo-Graefe phenomenon on looking down. The other case was acquired following head injury. Here there was narrowing of palpebral aperture on abduction and widening of palpebral aperture on adduction. Besides there was absence of elevation of the globe in looking up. The pseudo-Graefe phenomenon of lid retraction was present only on looking down and in and not on looking down and out. Probable causes of such associated movements have been mentioned.
