Strabismus

• Strabismus is an optical disorder which often causes double vision, or the splitting of one clear image into blurry double images. Physical signs of strabismus will usually manifest in early childhood; the key marker for this condition is the unnatural inward and/or outward turning of the eye(s) resulting in two separate foci. The inability to focus on a single object or in a single direction causes double vision. If left untreated, strabismus can lead to poor depth perception and even blindness in one eye. Surgery, therapy and corrective lenses can be used separately and in conjunction with each other to resolve strabismus in individuals of all ages.
  
  

Head Injuries

• Although many head injuries are not life-threatening, there are a host of symptoms to be cautious of experiencing in the event of this trauma. Double vision may occur immediately following or soon after a head injury, no matter what the initial cause of the injury was (blunt force, accidental or self-inflicted). Medical attention should be sought as soon as possible with the onset of double vision or any visual problems after a head injury as this can also signal serious brain trauma.
  
  

Diabetes

• Diabetes is an insulin disorder that affects many systems of the body, including the endocrine, nervous and circulatory systems. Although other symptoms of diabetes (such as rapid changes in weight, appetite and energy level) are more common, double vision and other sight issues can be indicators as well. If diabetes is suspected as the cause of double vision or other sight problems, it is vital that you receive medical attention so further damage does not occur. It should also be noted that if diabetes is in fact the culprit for the double vision, an optometrist should still be consulted in addition to physicians specializing in diabetic treatment.
