Diplopia 101: Causes, Symptoms, and Treatment of Double Vision
Updated: May 29, 2019
Diplopia is a condition characterized eye exam miami beach with double vision of a singular object when patients focus on one. Although the condition is usually observed in older patients, it has been known to occur in children of young ages.
Often, it is a symptom of an underlying condition that may be neurological or ocular in nature and requires a thorough assessment in light of accompanying symptoms to determine what the real cause is.
The condition is caused by a misalignment of the eyes, due to degenerative or congenital factors and may affect one or both eyes depending on the type of Diplopia. However double vision doesn’t always mean that you have the condition, in some cases such as when an object is too close to the eyes; it’s absolutely normal to see double.
The Types of Diplopia
Diplopia can be characterized into two separate categories depending on whether or not it affects both eyes. There are:
· Monocular Diplopia
· Binocular Diplopia
· Physiological Diplopia
Monocular diplopia is rather rare, with lower reporting rates than binocular Diplopia. Although it is also characterized by double vision, it doesn’t occur because there’s something wrong with both eyes but rather with only one eye.
It can be caused by light diffraction, in the sense that the light passing through the pupils is not being focused onto your retina to form a proper image due to cataracts. Other causes of the condition include swelling of the retinal tissue or problems with the ocular cortex in the brain which causes image processing dysfunctions.
The treatment for Monocular Diplopia depends on the underlying condition causing the double vision.
Binocular Diplopia is the more common form of double vision, which usually occurs because of the misalignment of the eyes. People with Binocular Diplopia can see completely normally if they close one eye; compared to Monocular Diplopia where the eye itself malfunctions rather than image processing dysfunction due to coordination problems between the two eyes.
The condition is also usually treated with corrective lenses or surgical procedures which can ensure that the eyes are properly aligned.
Occasional, longstanding horizontal diplopia is usually non urgent in nature. However, any sudden onset of diplopia, especially if it is not a horizontal diplopia must be assessed immediately. Pathological diplopia include neuropathies due to diabetes or hypertension, strokes and aneurysms.
