If the eye misalignment is vertical, one image appears on top of the other. If your eye misalignment is horizontal, the double image appears side by side. With double vision, the two images of a single object can appear next to each other in three ways - horizontally, vertically or diagonally. Which symptoms of diplopia you experience depend on the type of diplopia you have. Some of the neurological, ophthalmologic, autoimmune, infectious and neoplastic causes of diplopia include: Other causes include uncorrected refractive problems, media problems, dry eye syndrome, cataracts, cornea shape problems, corneal scarring, eye muscle problems, unstable tear film, wrong eyeglasses, media opacities, intraocular lens decentration (misalignment) and uveitis.Ĭranial nerve palsy, myasthenia gravis and orbital infiltration can also cause binocular diplopia.ĭouble vision can also signal the presence of a systemic disease, especially to a neurological or muscular process. Normally, your eye movements are coordinated, allowing images to be properly focused on your left and right retinas for single vision.īinocular diplopia can result from strabismus, a condition characterized by a misalignment of your eyes relative to each other. As a result, the object’s image falls outside the foveal area of your retina, triggering the perception of two images.ĭiplopia is largely caused by problems with the function of extraocular muscles. In these cases, while the fovea of one eye is directed towards an object, the fovea of the other eye is directed elsewhere. This type often disappears when either eye is covered. Binocular diplopia is a double vision that occurs when both your eyes are open.The additional image usually appears as a ghost. Monocular diplopia is a double vision that occurs when viewing with only one eye.There are two main types of double vision - monocular and binocular diplopia: Overfocusing on close objects or unfocusing on them can causes voluntary double vision. It can also be caused by the consumption of medications like opioids or benzodiazepines. Temporary diplopia may be caused by head injuries such as concussions, alcohol intoxication or strained/tired eye muscles. These problems may be the result of neuromuscular junction problems, mechanical problems, and cranial nerve disorders.ĭiplopia can be temporary or voluntary. The primary cause of diplopia is a malfunction of the extraocular muscles.ĭouble vision occurs when problems in eye muscles or nerves cause the image to be focused on different locations on each retina. You can have double vision, also called diplopia, in one or both eyes. Duplicate images can appear vertical to each other, horizontal or diagonal.

Introĭouble vision is a condition that refers to seeing two images of one object at the same time. The primary cause of diplopia is a malfunction of the extraocular muscles. You can have double vision, or diplopia, in one or both eyes.

Duplicate images can manifest vertical to each other, horizontal or diagonal. Double vision refers to seeing two images of one object at the same time.
