edrophonium and Esotropia

edrophonium has been researched along with Esotropia in 2 studies

Edrophonium: A rapid-onset, short-acting cholinesterase inhibitor used in cardiac arrhythmias and in the diagnosis of myasthenia gravis. It has also been used as an antidote to curare principles.
edrophonium : A quaternary ammonium ion that is N-ethyl-N,N-dimethylanilinium in which one of the meta positions is substituted by a hydroxy group. It is a reversible inhibitor of cholinesterase, with a rapid onset (30-60 seconds after injection) but a short duration of action (5-15 minutes). The chloride salt is used in myasthenia gravis both diagnostically and to distinguish between under- or over-treatment with other anticholinesterases. It has also been used for the reversal of neuromuscular blockade in anaesthesia, and for the management of poisoning due to tetrodotoxin, a neuromuscular blocking toxin found in puffer fish and other marine animals.

Esotropia: A form of ocular misalignment characterized by an excessive convergence of the visual axes, resulting in a cross-eye appearance. An example of this condition occurs when paralysis of the lateral rectus muscle causes an abnormal inward deviation of one eye on attempted gaze.

Research Excerpts

ExcerptRelevanceReference
"A 70-year-old man with known vascular disease, who had bilateral internuclear ophthalmoplegia, and an 18-month-old girl with a long-term variable esotropia culminating in a postinfectious oculopharyngeal neuropathy both responded with a positive edrophonium chloride (Tensilon) test, strongly suggesting the diagnosis of myasthenia gravis."3.66Ocular myasthenia gravis mimicking pseudointernuclear ophthalmoplegia and variable esotropia. ( Acers, TE, 1979)
"When myasthenia gravis is suspected, the presence of sustained gaze fatigue provides a tentative clinical diagnosis to be confirmed by pharmacologic testing."1.26Myasthenic sustained gaze fatigue. ( Glaser, JS; Osher, RH, 1980)
