Diplopia or double vision can be the most frustrating of all eye conditions. The most common form of diplopia (binocular diplopia) arises when the eyes are misaligned and the symptoms may be constant or intermittent.

The affects of binocular diplopia will cause images to appear vertically, horizontally or diagonally double due to misalignment or imbalance in the actions of each of the eye muscles that control movement of each eyeball.

Examination is required to exclude pathology as a possible reason for loss of binocular vision.

In many cases the onset of diplopia can be due to age as the loss of accuracy and flexibility in the muscles may be one of the reasons for double vision.

Other reasons for diplopia include head injuries or secondary to other illnesses, so examination is very important if double vision is noticed either binocularly or even if just in one eye, ie monocular diplopia.

Divergence Insufficiency is associated with an Esotropia. In this case the inward eye turn is greater at distance than at near.

Management involves a program of Vision Therapy and may also require spectacles to try and control the deviation, ie to assist the eyes in working together and looking straight.

Word of the Moment

Diplopia (Double Vision)
Double vision usually arises when the eye muscles of each eye do not co-ordinate accurately, causing the position of one eyeball to not coincide with the other. Examination is necessary to ascertain if this is due to binocular vision problems or secondary to eye disease, hence requiring medical referral if this were to be the case. more
