Is Lazy Eye the Same as Strabismus? Difference between Amblyopia (Lazy Eye) & Strabismus?

Difference between (Lazy Eye) & Strabismus

What is Lazy eye?

Amblyopia or lazy eye is an imaginative and prescient impairment due to terrible coordination with the mind. Although there may be no disorder that hinders the visible capability of the eyes, the mind gets poorer high-satisfactory visible facts from certainly considered one among them, so it offers desire to the attention that sees better. This reasons the alternative eye now no longer to be inspired or paintings difficult sufficient and it finally ends up becoming “lazy”.

Amblyopia or lazy eye commonly develops at an early age and is the main purpose of adolescence or childhood vision loss. For this reason, it is very essential to have an early eye exam by an ophthalmologist and have it corrected as early as possible.

Amblyopia (Lazy Eye) and Strabismus – similarities and differences

Similarities –

Gathering the difference between strabismus and amblyopia can be confusing, as the two functional vision problems partake some analogous characteristics. Strabismus is a problem with eye alignment, in which both eyes don’t look at the same place at the same time. Amblyopia is a problem with visual perceptivity, or sight. Even with traditional spectacles or lens, a person with amblyopia cannot see an image easily in one or both eyes.

Differences –

The terms amblyopia (or lazy eye) and strabismus are frequently confused and occasionally used interchangeably to relate to both. As we’ve seen, lazy eye consists of low vision in one or both eyes, which causes the brain to give preference to the bone that sees better and ignore the other, which becomes “lazy”. Strabismus, on the other hand, is the misalignment of the eyes that causes them not to look at the same direction.
A lazy eye is in numerous cases a consequence of strabismus. This occurs because the person affected by strabismus gives preference and keeps straight the eye so that’s easier for him to concentrate on images and gets used to using only that eye. Meanwhile, the swerved eye doesn’t work, so it runs the threat of getting “lazy”.

Amblyopia (Lazy Eye) Vs. Strabismus: Types:

Types of Amblyopia (Lazy eye) –

All three types of amblyopia are a result of suppression of vision in one or both eyes. The difference is in the root cause of the suppression.
Refractive amblyopia: Results from an uncorrected high prescription in one or both eyes.

Strabismic amblyopia: Results from a constant eye turn in one eye.
Deprivation amblyopia: Results from impaired vision in one eye due to physical problems in the eye.

Types of Strabismus –

Types of strabismus are determined by the following:

  • Which of the two eye turns
  • Direction of the eye turns in
  • Frequency of the eye turn
  • Amount of the curve the of eye turn
  • Whether the turn is the same in all positions of gaze

Amblyopia (Lazy Eye) Vs. Strabismus: Symptoms

Symptoms of Amblyopia –

Strabismus is pretty easy to spot but you can’t detect amblyopia with simple observation, as there are no outward signs.

However, because this is a functional vision problem, typical symptoms involve:

  • Poor depth perception
  • Difficulty catching and throwing objects
  • Clumsiness
  • Squinting or shutting an eye
  • Head turn or tilt
  • Eye strain
  • Fatigue with near work

Symptoms of Strabismus –

The most common symptom of strabismus is an observable eye turn. Patients with constant strabismus tend to be less symptomatic (but not asymptomatic) when compared to patients with non-strabismic functional vision problems. That’s because they often suppress the information from the eye that is turning, thus avoiding double vision and some of the accompanying symptoms of poor eye teaming.

Patients with intermittent strabismus may experience more frequent symptoms of a functional vision problem. These include:

  • Poor depth perception
  • Eye and/or general fatigue
  • Headaches
  • Eye strain and/or pain
  • Blurry or double vision

Amblyopia (Lazy Eye) Vs. Strabismus: Causes

Causes of Amblyopia –

Anything that blurs the vision of a child or leads to a cross in the eye can result in lazy eye. Common causes of the condition include:
Muscle imbalance (strabismus amblyopia) – The most common cause of lazy eye is an imbalance in the muscles that position the eyes. This imbalance can cause the eyes to cross in or turn out, and prevents them from working together.

Difference in sharpness of vision between the eyes – Also known as refractive amblyopia, a significant difference between the prescriptions in each eye — often due to farsightedness but sometimes to nearsightedness or an uneven surface curve of the eye (astigmatism) — can result in lazy eye. Glasses or contact lenses are typically used to correct these refractive problems. In some children lazy eye is caused by a combination of strabismus and refractive problems.

Deprivation – A problem with one eye — such as a cloudy area in the lens (cataract) — can prohibit clear vision in that eye. Deprivation amblyopia in infancy requires urgent treatment to prevent permanent vision loss. It’s often the most severe type of amblyopia.

Amblyopia (Lazy Eye) Vs. Strabismus: Risk Factors

Factors associated with an increased risk of lazy eye include:

  • Premature birth
  • Small size at birth
  • Family history of lazy eye
  • Developmental disabilities

Factors associated with Strabismus –
Significant risk factors for strabismus reported by the studies included low birth weight, cicatricle retinopathy of prematurity, prematurity, smoking throughout pregnancy, anisometropia, hyperopia, and inheritance.

Amblyopia (Lazy Eye) Vs. Strabismus: How is it diagnosed?

Your doctor will conduct an eye exam, checking for eye health, a wandering eye, a difference in vision between the eyes or poor vision in both eyes. Eye drops are generally used to dilate the eyes. The eye drops causes blurred vision that lasts for several hours or a day.

Your ophthalmologist will conduct an eye test, checking for eye health, a wandering eye, a difference in vision between the eyes or poor vision in one or both eyes. The eye drops that he generally uses to dilate the eyes leave the vision a little blurry. This blurriness lasts for hours.

The method used to test vision depends on your child’s age and stage of development:

  • Preverbal children. A lighted magnifying device can be used to detect cataracts. Other tests can assess an infant’s or toddler’s ability to fix his or her gaze and to follow a moving object.
  • Children age 3 and older. Tests using pictures or letters can assess the child’s vision. Each eye is covered in turn to test the other.

Amblyopia (Lazy Eye) Vs. Strabismus: Treatment

Strabismus, or crossed eyes, does not inescapably mean that a case requires vision correction. They may have20/20 vision, but just suffer with eye alignment. Amblyopia, on the other hand, occurs when an eye does not have normal visual perceptivity.

Amblyopia (Lazy Eye) Vs. Strabismus: When To See Doctor

Strabismus and amblyopia can be corrected, but it is important to catch them beforehand. Be sure to schedule an appointment with your ophthalmologist for your children, particularly before they reach the age of four, in expedients of catching any implicit problems beforehand.
