Amblyopia, also known as lazy eye is a visual disorder that usually begins in childhood and prevails into adulthood. In this condition, one of the two eyes fails to achieve normal visual acuity, even prescription eyeglasses and contact lenses become useless. It is important for patients to understand and become aware of the causes and treatment of amblyopia to cope with the condition.
In this article, we will delve into the amblyopia causes and treatment and also introduce the most professional eye hospital, reckoned for its expertise in treating eye conditions like amblyopia.
Understanding Amblyopia:
It is mainly characterised by reduced vision in one eye, when the brain fails to control both eyes simultaneously. This misalignment leads to the brain favouring one eye over the other, leading to poor visual development in the eye which is ignored .
Some common symptoms of amblyopia include:
- Blurred vision in one eye
- Poor depth perception
- Squinting or shutting one eye
- Eyes that do not appear to work together
- Difficulty with tasks requiring sharp vision, such as reading or driving
There are various misconceptions regarding amblyopia such as it affects only children. However, studies have shown adults can also suffer from it. Amblyopia greatly impacts the quality of life. In adults, it may lead to various challenges, including, reduced confidence, and career limitations.
Amblyopia Causes and Treatment
Causes of amblyopia
Amblyopia can arise from various underlying issues that disrupt the normal development of vision. Here are some of its common causes:
Genetic Factors:
Genetics play a significant role in the development of Amblyopia eye disease. If you have a family history of amblyopia or any other eye conditions, it can increase your
chances of developing the disorder. While genetics alone can not be the sole cause, it can contribute to an elevated risk.
Strabismus or Misalignment of the Eyes:
Crossed or misaligned eyes are one of the leading causes of amblyopia. In this condition, the eye does not line properly. Hence, the brain focuses on one eye and ignores the visual input from the misaligned eye. Ultimately, this leads to amblyopia in the neglected eye. Different types of strabismus include esotropia (inward turning of the eye) and exotropia (outward turning of the eye), which lead to lazy eyes.
Refractive Errors (Myopia, Hyperopia, Astigmatism):
Another significant cause of amblyopia is refractive errors such as myopia (nearsightedness) , hyperopia (farsightedness) and astigmatism (blurred vision due to irregular shape of cornea). The one eye that has lower degree of refractive error compared to the other, is favored by the brain. It leads to amblyopia in the other eye with greater refractive error. This type of amblyopia is also referred to as refractive or anisometropic amblyopia.
Cataracts and Other Eye Conditions
Cataracts, a serious eye condition in which the eye’s lens become cloudy, leading to obstructed vision. If left untreated, cataracts may give rise to amblyopia. Apart from cataracts, other eye conditions such as ptosis (drooping eyelid) or corneal opacities which cause reduced vision, can also result in amblyopia.
Neurological Issues
Less common but an important cause of amblyopia is development of neurological issues. Conditions that impact the optic nerve are the visual cortex can be a potential cause of amblyopia.
Identification of the root cause helps healthcare providers to tailor treatment plants and cope with the specific issues according to every patient’s unique need.

This test measures the clarity of vision in each eye. Patients are required to read letters in symbols on an eye chart from a specific distance. Visual acuity of the affected eye is usually lower as compared to the other eye.
Refraction Test:
Refraction tests are for you to determine the degree of refractive error in each eye. A phoropter or a retinoscope is used to assess how light is focused in the eye, and you identify any differences in the refractive between the two eyes.
Cover Test:
This test aims to discover how well the eyes work together and detect any misalignment. In this test one eye is covered and the patient is asked to focus on an object. Then the cover is moved to the other eye to observe any movement in the eyes to detect strabismus.
Binocular Vision Test:
Binocular vision tests evaluate how well both eyes were together to form a single clear image. This shows underline issues with depth perception and eye coordination, which are an indication of amblyopia.
Pupillary Response Test:
This test is carried out to check how pupils react to light. It is helpful in identification of any neurological issues that may be contributing to amblyopia.
Ocular Health Examination:
A thorough examination of the eye’s internal and external structure is necessary for the detection of various underline eye conditions such as cataracts or retinal abnormalities that may be causing amblyopia.
