DIPLOPIA

DIPLOPIA:Commonly known as double vision, is the simultaneous perception of two images of a single object that may be displaced horizontally, vertically, diagonally or rotationally in relation to each other..It is usually the result of impaired function of the extraocular muscles (EOMs),where both eyes are still functional but they cannot converge to target the desired object..Problems with EOMs may be due to mechanical problems, disorders of the neuromuscular junction, disorders of the cranial nerves,that stimulate the muscles, and occasionally disorders involving the supranuclear oculomotor pathways or ingestion of toxins.

Diplopia can be one of the first signs of asystemic disease, particularly to a muscular or neurological process,and it may disrupt a person’s balance, movement, and/or reading abilities.

The appropriate treatment for binocular diplopia will depend upon the cause of the condition producing the symptoms. Efforts must first be made to identify and treat the underlying cause of the problem. Treatment options include eye exercises,wearing an eye patch on alternative eyes,prism correction,and in more extreme situations, surgeryor botulinum toxin.

If diplopia turns out to be intractable, it can be managed as last resort by obscuring part of the patient's field of view. This approach is outlined in the article on diplopia occurring in association with a condition called horror fusionis.
