A spasm of accommodation (also known as a ciliary spasm, an accommodation, or accommodative spasm) is a condition in which the ciliary muscle of the eye remains in a constant state of contraction. Normal accommodation allows the eye to "accommodate" for near-vision. However, in a state of perpetual contraction, the ciliary muscle cannot relax ...
Accommodative esotropia (also called refractive esotropia) is an inward turning of the eyes due to efforts of accommodation. It is often seen in patients with moderate amounts of hyperopia . The person with hyperopia, in an attempt to "accommodate" or focus the eyes, converges the eyes as well, as convergence is associated with activation of ...
Acquired non-accommodative strabismus and secondary strabismus are developed after normal binocular vision has developed. In adults with previously normal alignment, the onset of strabismus usually results in double vision. A child with accommodative esotropia affecting the right eye
Esotropia: Acute onset esotropia may occur in accommodative spasm, which is the common cause of pseudomyopia. [2] Diplopia: Diplopia may occur due to esotropia or convergence spasm; The diagnosis is done by cycloplegic refraction using a strong cycloplegic like atropine or homatropine eye drops. Accommodative amplitude and facility may be ...
Accommodative infacility is also known as accommodative inertia. [52] In this condition there will be difficulty in changing accommodation from one point to other. There may be difficulty in adjusting focus from distance from near. [51] It is a comparatively rare condition.
Vergence control, and over-convergence associated with the extra accommodation required to overcome a hyperopic refractive error, play a role in the onset of accommodative esotropia. The classical explanation for the onset of accommodative esotropia is a compensation of far-sightedness by means of excessive accommodative convergence.
Accommodative insufficiency (AI) involves the inability of the eye to focus properly on an object. Accommodation is the adjustment of the curvature of the lens to focus on objects near and far. In this condition, amplitude of accommodation of a person is lesser compared to physiological limits for his age. [ 1 ]
It is used as an ocular antihypertensive in the treatment of open angle glaucoma and, in some cases, accommodative esotropia. It is available under several trade names such as Phospholine Iodide (Wyeth-Ayerst). Echothiophate binds irreversibly to cholinesterase. Because of the very slow rate at which echothiophate is hydrolyzed by ...
