Though these symptoms can indicate esophoria, they can also be signs of other various eye conditions. Other eye misalignment conditions, including exophoria and strabismus can present similar symptoms. SymptomsĮsophoria is a vision condition that affects eye coordination. In some cases, an untreated phoria may eventually progress to a tropia. When fatigued, a person may not be able to overcome their phoria and the eye will drift. Hypophoria and hypotropia – Downward turn of the eyesĮach type of tropia is a form of strabismus and may cause more problems for vision than phorias, since it is present at all times. Hyperphoria and hypertropia – Upward turn of the eyes Some other types of phorias and their tropia counterparts include:Įxophoria and exotropia – Outward turn of the eyes Both phorias and tropias are often found in childhood.īoth esophoria and esotropia cause the eye to drift inward, but the main difference is that esotropia is usually constantly present, and esophoria is not. However, phorias cause occasional misalignment when fusion is broken, and tropias usually present a constant deviation.

Fusion can break between the eyes when the eyes focus on a near object and one eye turns inward more than necessary. Eyes appear to work together normally in patients with esophoria, but if the fusion, or binocular vision, between the eyes is broken, an inward deviation can appear. Esophoria definitionĮsophoria is an inward turn or deviation of the eye that only occurs some of the time. If a person has esophoria, however, one eye tends to drift inward if binocular vision is disrupted and both eyes are not focusing on a single object. Typically, the eyes align so that their movement is coordinated at all times.
