Double vision (Diplopia) occurs when a patient fixates on a single object, but perceives two objects instead. Caused by a number of disorders, Diplopia can be monocular or binocular.
Monocular Diplopia does not go away when either eye is closed. This type of Diplopia can be caused by defects in the front part of the eye involving the cornea and lens, such as corneal scars, Cataracts, or the need for glasses.
Binocular Diplopia, however, does go away when either eye is closed. It is caused by a misalignment of the eyes, which can be secondary to many disorders, most often neurogenic (nerve related) or myopathic (muscle related).
