Anisometropia Introduction

Anisometropia relates to a state of visual condition in which a person has a difference of vision between the two eyes. In other words, anisometropia affected person tends to see a larger image in one eye .It is also called as asthenopia.

ICD-10 H52.3
ICD-9 367.31

According to a study, 6% of those who are affected with Anisometropia are between the ages of 6 and 18. Anisometropia has the potentialities of causing binocular vision in infants. Often, it occurs in the early stages of childhood. Particularly, it is on the ascendancy when the children enter the age of three years. Subsequently, doctors cannot detect the problem until after a certain stage as traditional screening is done during the same period. Children suffering from anisometropic eye can lose their sight in case of neglecting it for a long period of time.

Symptoms of Anisometropia

  • Headaches
  • Eye strain
  • Light-sensitivity
  • Complexity in reading
  • Nausea
  • Double vision
  • Faintness
  • Sheer Tiredness
  • Impaired depth perception

Treatment of Anisometropia

Age of the patient and the extent of amblyopia in the eye are the two essential factors in the response to treatment. The need for taking treatment to deal with Anisometropia relies on the magnitude of the problem it has. It varies from individual to individual. As a result, it obviates the need to go for further treatment. However, the problem of Anisometropia can be dealt with in the following manner:

  • Wearing Contact lenses
  • Wearing Glasses

What causes Anisometropia?

There are varied causes of Anisometropia such as:

  • Inborn defects in the eye
  • Uneven growth in both eyes
  • Miscalculation of intraocular lens power during the post cataract surgery.

Anisometropia Types

There are different types of Anisometropia in existence like

 

  1. Simple Anisometropic Eye - Under this condition, mere one eye get impacted while the other eye tends to be normal. It is also called simple myopic or simple hypermetropic.
  2. Compound Anisometropic Eye - This is the case wherein both the eyes are in the state of myopic but with a notable difference in the refractive power.
  3. Mixed Anisometropic Eye – This is the last stage wherein both eyes have refractive errors. Also, one eye is hypermetropic whereas the second eye is myopic.
