What is Lazy Eye?

Known as Lazy Eye popularly, Amblyopia is an abnormal visual development that can be quite annoying. It causes poor vision in infancy and early childhood.

Lazy eye affects only one eye, and only the healthy eye is used for vision. Thus, it also develops other problems. When Amblyopia affects both eyes; there is a severe loss of vision.

Why does it happen?

When the nerves that carry information from the eyes to the brain gets damaged due to any reason, the problem of Amblyopia occurs. The damage could happen due to many reasons.

When the brain gets a blurred image or the incorrect image, it gets confused. With time, the brain favors only healthy eye and ignores the signals received from the weaker eye.

What symptoms indicate the presence of Lazy Eye?

Typically, the problem is detected by the presence of

  • One eye wander in or out unintentionally
  • Both eyes do not work in coordination
  • Poor vision in one eye
  • Poor perception of depth

If any of the symptoms are observed, then it should be reported to a qualified eye specialist. DPEH Pune is an advanced and well-equipped eye hospital where the problem is investigated and diagnosed well.

Types of Lazy Eye

Amblyopia is classified into multiple categories:

  • Strabismic Amblyopia: It is also known as Cross Eye. It develops when one eye turns up, down, in or out against the healthy eye.
  • Refractive Amblyopia: When there is a large or unequal refractive error, the weaker eye develops Amblyopia.
  • Deprivation Amblyopia: It happens due to the presence of cataract or other vision problems.


When a patient is diagnosed for Lazy Eye, doctors understand the fundamental cause first. Based on that, they plan the line of treatment.

A complete eye examination is conducted to detect lazy eye. The difference in the vision between the wandering eye and the healthy eye is checked.

Sometimes, the ‘red reflex test’ is carried out using ophthalmoscope if doctors suspect the presence of cataract.

Specialized methods are used to diagnose Amblyopia among infants, toddlers and preschoolers, and older kids.

Additionally, doctors carry out a detailed examination of the eyes to check inflammation, tumor, etc.

The therapy options depend on the fundamental reason for the problem and the degree of lazy eye impairing the vision.

Conservative treatment options are the use of eye patch that covers the stronger eye so that the weaker eye gets stimulated. It can be used for three to six hours depending on the need. Thus, the part that controls the eye gets activated again, and the problem is resolved.

Sometimes, eye drops are prescribed to blur the vision of the healthy eye temporarily. It is an alternate for eye patches.

Corrective eyewear (contacts or specs) are prescribed if the Lazy Eye is caused due to refraction errors.

Surgery is also performed at DPEH Pune to repair the eye muscles. To correct cataract or droopy eyelids also doctors recommend surgery.
