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 ]
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 ...
But, due to this accommodative effort for distant vision, people may complain of eye strain during prolonged reading. [2] [7] If the hypermetropia is high, there will be defective vision for both distance and near. [2] People may also experience accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus. [3]
Accommodative excess may be seen in the following conditions: [3] Hypermetropia : Young hypermetropes use excessive accommodation as a physiological adaptation in the interest of clear vision. Myopia : Young myopes performing excessive near work may also use excessive accommodation in association with excessive convergence.
This is a shortened version of the sixth chapter of the ICD-9: Diseases of the Nervous System and Sense Organs.It covers ICD codes 320 to 389.The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9.
The following symptoms may be seen in patients with pseudomyopia Blurring of distance vision: Intermittent blurring of distant vision after prolonged near work is the main symptom of pseudomyopia. Asthenopia; Headache; Eyestrain; Photophobia [1] Esotropia: Acute onset esotropia may occur in accommodative spasm, which is the common cause of ...
Accommodative infacility also known as accommodative inertia [1] is the inability to change the accommodation of the eye with enough speed and accuracy to achieve normal function. This can result in visual fatigue , headaches , and difficulty reading . [ 2 ]
Accommodative insufficiency is the condition where amplitude of accommodation of a person is lesser compared to physiological limits for their age. [50] Premature sclerosis of lens or ciliary muscle weaknesses due to systemic or local cases may cause accommodative insufficiency. [50]
