Diplopia Health Dictionary

Also known as diplopia, the seeing of 2 instead of 1 visual image of a single object. It is usually a symptom of a squint, especially of paralytic squint, in which paralysis of 1 or more of the eye muscles impairs eye movement. Other causes include a tumour in the eyelid or a tumour or blood clot behind the eye. Double vision can also occur in exophthalmos, when the eyeballs protrude because of an underlying hormonal disorder. A child with squint needs treatment to prevent amblyopia (lazy eye). In adults double vision needs immediate investigation.... double vision

Autoimmune disorder. Nerve weakness due to defective nerve impulse transmission. Rare. Neuro-muscular disease with spells of extreme weakness. Sight, voice and breathing are most at risk. Often misdiagnosed as neurosis. Muscles fail to respond to directions from the brain. May be associated with a tumour of the thymus, removal of which is curative.

Symptoms: weakened eye muscles producing drooping eyelids (ptosis). Double vision (diplopia). Weakness of neck muscles served by the cranial nerves. Thymus gland abnormality. Difficult swallowing, chewing, slurred speech, fatigue, ‘simply cannot hold her head up’.

Lid-lag test and Tensilon tests establish diagnosis.

Treatment should give support to the thymus gland.

Alternatives. To improve nerve transmission: but not cure. Ephedra tea BHP (1983). 1 teaspoon to each cup boiling water; infuse 15 minutes, thrice daily.

Formula. Oats 2; Ginseng 1; Sarsaparilla 1; pinch Cayenne or drops Tincture Capsicum. Dose: Liquid Extracts: 1 teaspoon. Tinctures: 2 teaspoons. Powders: 500mg (two 00 capsules or one-third teaspoon). Thrice daily.

Practitioner: Ephedrine.

Diet: Gluten-free. ... myasthenia gravis (mg)

Indistinct or fuzzy visual images. Blurred vision, which should not be confused with double vision (diplopia), can occur in 1 eye or both, for episodes of varying lengths of time, and can develop gradually or suddenly. The usual cause of longstanding blurred vision is a refractive error such as astigmatism (unequal curvature of the front of the eye), hypermetropia (longsightedness), or myopia (shortsightedness), all of which can be corrected by glasses or contact lenses. After the age of 40, presbyopia (reduced ability to focus on near objects) becomes more common.

Vision may also be impaired or blurred as a result of damage, disease, or abnormalities of parts of the eye or its connections to the brain.

The most common causes of blurred vision as a result of disease are cataract and retinopathy.... blurred vision

an increasingly recognized type of persistent headache in a patient with no history of headaches. Features include headache that is worse on standing and resolves on lying flat. It may be associated with other symptoms, such as dizziness, tinnitus, and (rarely) *diplopia. The commonest cause is a complication of lumbar puncture, but it may occur spontaneously (spontaneous intracranial hypotension) after a dural tear resulting in a leak of cerebrospinal fluid. Treatment is with bed rest and increased intake of fluids; caffeine orally or intravenously is also used. In cases that do not resolve, an epidural blood patch procedure is performed, in which a small quantity of the patient’s blood is slowly injected into the *epidural space to seal the leak.... intracranial hypotension headache

n. the sensation of multiple images of one object. It is sometimes experienced by people with early cataract. See also diplopia.... polyopia
