Exotropia caused by pit viper snakebite.

30 Jul 2009 Pit viper snake venom exerts a mildly neurotoxic effect that may rarely lead to neurotoxic complications, such as paralytic strabismus. Extraocular muscles are known to be particularly susceptible to this complication. In previously reported cases, ... Read more...

[Case of multiple sclerosis with WEBINO syndrome]

30 May 2009 We report a 50-year-old man presenting with wall-eyed bilateral internuclear opthalmoplegia (WEBINO) syndrome. He had suffered from progressive double vision and tetraparesis, and been diagnosed as secondary progressive multiple sclerosis (MS). On ... Read more...

Acquired cyclic exotropia and hypotropia.

30 May 2009 Cyclic exotropia, a very rare condition, consists of periods of exotropia and orthotropia alternating on a regular, most commonly 48-hour, cycle. Cyclic vertical deviations, including cyclic oculomotor nerve palsy, also are extremely uncommon. ... Read more...

Technical information about 'Exotropia'

Definition: A form of ocular misalignment where the visual axes diverge inappropriately. For example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. An exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.
