Tröger's base is a white solid tetracyclic organic compound. Its chemical formula is (CH 3 C 6 H 3 NCH 2) 2 CH 2. Tröger's base and its analogs are soluble in various organic solvents and strong acidic aqueous solutions due to their protonation. It is named after Julius Tröger, who first synthesized it in 1887.
Base-out prism reading, stereogram cards, computerized training programs are used to improve fusional vergence. The wearing of convex lenses. The wearing of concave lenses. "Cawthorne Cooksey Exercises" also employ various eye exercises, however, these are designed to alleviate vestibular disorders, such as dizziness, rather than eye problems.
Blepharophimosis-ptosis-esotropia-syndactyly-short stature syndrome. Blepharophimosis-ptosis-esotropia-syndactyly-short stature syndrome is a very rare genetic and congenital disorder which is characterized by blepharophimosis, ptosis, V-esotropia, foot syndactyly, extra-ocular and frontal muscles weakness, low height/short stature, prognathism ...
The management of strabismus may include the use of drugs or surgery to correct the strabismus. Agents used include paralytic agents such as botox used on extraocular muscles, [1] topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia.

Dissociated vertical deviation. Dissociated vertical deviation ( DVD) is an eye condition which occurs in association with a squint, typically infantile esotropia. The exact cause is unknown, although it is logical to assume it is from faulty innervation of eye muscles.
Convex polyhedral prisms. The most obvious family of prismatic 4-polytopes is the polyhedral prisms, i.e. products of a polyhedron with a line segment.The cells of such a 4-polytope are two identical uniform polyhedra lying in parallel hyperplanes (the base cells) and a layer of prisms joining them (the lateral cells).
Hypertropia is a condition of misalignment of the eyes ( strabismus ), whereby the visual axis of one eye is higher than the fellow fixating eye. Hypotropia is the similar condition, focus being on the eye with the visual axis lower than the fellow fixating eye. Dissociated vertical deviation is a special type of hypertropia leading to slow ...
