Esotropia Causes And Types

Esotropia Causes And Types

Esotropia is an eye condition in which both or one eye turns inward. Due to this, it gives the appearance of crossed eyes. The problem can develop at any age and there are different forms linked with it. In this guide, we are going to discuss its causes and types.

What Is Esotropia?

Esotropia is described when the eye turns inward and in infants the most common type is strabismus. Young children facing this condition do not know how they can use their eyes together. In most cases, bifocals, special glasses, or early surgery will help to align the eyes and this way the permanent vision loss is prevented.

In the case of infants, the intermittent crossing of the eyes gets normal in 4 to 5 months. If the problem is persistent then there is a need to consult the eye doctor right away. Visiting the eye hospital at the right time will help to address the issue and prevent it from increasing.

Causes of Esotropia

The esotropia cause depends on when it occurred for the first time. In adults, if the problem occurred suddenly then it means treatment is needed right away. In the case of infants and toddlers, it means the sign of abnormal development which is a brain issue. It is normal to have intermittent crossing below the month of 4 to 5.

Possible reasons increase risk of esotropia

  • Diabetes
  • Premature birth
  • Family history
  • Genetic disorders
  • Hyperthyroidism
  • Neurological disorders

Some of the underlying conditions are:

  • The eye issue due to a thyroid problem
  • Horizontal eye movement problem
  • Poor vision
  • Stroke
  • hydrocephalus (excess fluid on the brain)

Types of Esotropia


  • Congenital esotropia


This type of esotropia occurs in infants when they are born. The reason is abnormal development in the motor area or abnormal wiring of the nerves. This condition occurs between 2 to 4 months and it might be possible that the eye turns large.

Infants who are facing this issue do not have enough amount of nearsightedness or farsightedness. The issue occurs when the binocular system has abnormal development. The ideal way to solve the problem is with surgery. The surgery does not aim in solving the working of the eye but it helped in correcting the eye cosmetic appearance.


  • Accommodative esotropia


This problem occurs in people at the age of 2. the problem occurs in eye muscles and eye focus. The focusing system allows the eye to focus on the subject and change the eye power. The alignment system helps in controlling the working of both eyes.

In young children, the focusing power is very huge and sometimes they over-focus on certain things. Due to this, the problem of uncorrected vision can occur.

If you are facing this condition then it is best to seek the help of the doctor right away.
