Convergence insufficiency. Convergence Insufficiency. Other names. Convergence disorder. Specialty. Ophthalmology, optometry. Convergence insufficiency is a sensory and neuromuscular anomaly of the binocular vision system, characterized by a reduced ability of the eyes to turn towards each other, or sustain convergence .
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 ...
Secondary to Convergence insufficiency. Accommodative excess may occur secondary to convergence insufficiency also. In convergence insufficiency near point of convergence will recede, and positive fusional vergence (PFV) will reduce. So, the patient uses excessive accommodation to stimulate accommodative convergence to overcome reduced PFV.
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]
Parinaud's syndrome is a constellation of neurological signs indicating injury to the dorsal midbrain. More specifically, compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF). It is a group of abnormalities of eye movement and pupil dysfunction and is named for Henri Parinaud [6 ...
Neurology. Central pain syndrome, also known as central neuropathic pain, [1] is a neurological condition consisting of constant moderate to severe pain due to damage to the central nervous system (CNS) which causes a sensitization of the pain system. [2] [3] The extent of pain and the areas affected are related to the cause of the injury.
Paregoric was a household remedy in the 18th and 19th centuries when it was widely used to control diarrhea in adults and children, as an expectorant and cough medicine, to calm fretful children, and to rub on the gums to counteract the pain from teething. A formula for paregoric from Dr. Chase's Recipes (1865): [7]
For others with more mild depression or moderate symptoms of depression, over-the-counter medication might seem like the better choice. And if you decide to explore this route, it’s never a bad ...
