Amblyopia is commonly known as'lazy eye. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to'see' and develop binocularity, that is the ability to perceive depth (stereoacuity). This occurs in the first 8 to 10 years of life. 

Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions (adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to'see' and becomes'lazy. This condition is seen in 1-4% of population.

The common causes for dissimilar images or amblyopia are:
1. Misalignment of the eyes or squint: it is the primary reason for amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different, resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.

2. Refractive amblyopia:
A. Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5d of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
B. High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.

3. Cloudiness in visual system or visual deprivation amblyopia: any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood (drooping of one eyelid, eyelid swelling, patching of one eye).

Treatment for amblyopia
For treatment of amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.

Patching or occlusion of the good eye
This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye'learns to see. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.

To be effective, treatment should be implement as early as possible, within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.

Homeopathic and Natural Treatment for Eye Allergies

In order to see clearly, the eyes need to be constantly lubricated. This function is performed by small glands located in the eyelids known as meibomian glands. These glands secrete oil onto the surface of the cornea through tiny openings on them. Malfunctioning of this gland can create an excessive amount of oil.

When oil accumulates on the eyelids, it encourages the bacteria present in the eye and the skin around it to multiply leading to inflammation. This condition is known as meibomianitis. Adults are at a higher risk of suffering from this condition as compared to children.

Some of the factors that could trigger meibomianitis are:

Allergic reactions
Fluctuation of hormones associated with puberty and adolescence
Acne and other skin conditions
Lice or mites on the eyelashes
Unsanitary contact lens solution
Contaminated eye makeup
Certain medications such as isotretinoin for acne that increases bacteria on the eyelids
However, in some cases, a clear trigger factor may not be identifiable.
Some of the characteristic symptoms of this disease are:

Dry eyes
Constant watering from the eyes
Inflammation and reddening of the eyelids
Burning sensation in the eyes
Itchiness
Flaking of skin around the infected eye
Heightened sensitivity to light
Excessive blinking
Crusting of eyelashes
Blurred vision
Frequent formation of sties
Loss of eyelashes or abnormal growth of eyelashes
Regular cleaning of the eyes with warm water and abstaining from the use of contact lenses and eye makeup can help reduce irritation and manage the inflammation. Additionally, the doctor may also prescribe antibiotics or steroids in the form of pills, eye creams or drops. Artificial tears may also be recommended to patients exhibiting dry eye symptoms.

Meibomianitis - 8 Things That Can Trigger It!

As you reach the age of 40, you will likely notice changes in your vision. Perhaps you have difficulty reading a book without glasses, or distinguishing between colours. These changes occur as an effect of ageing. However, nowadays people in their teens are also exposed to a host of eye disorders and vision problems, mostly resulting from eye injuries and visual stress.

The most common disorders of the eye, which affect the age group 19-40, are Refractive errors. The following signs and symptoms characterize such disorders-

  Haziness
  Double vision
  Halos or glares when you are surrounded by bright lights
  Headaches
  Squinting
  Eye strain

What are the Refractive errors?

Refractive errors develop when light cannot focus on the retina (the light-sensitive tissue situated at the rear side of the eye) directly due to the shape of the eye. The change in the cornea s shape, the ageing of the lens, or the length of your eyeball can lead to refractive errors. Most people suffer from one or more of the above conditions.

Type of Refractive Errors:

Following are the most common types of refractive errors-

  Myopia or Nearsightedness - If you have this condition, you will see nearby objects clearly but distant objects will appear blurry. This happens because the light comes to focus right in front of the retina, instead of on the retina.

  Hyperopia or Farsightedness - This condition is just the opposite of myopia. Distant objects are clearly visible but those located close to you appear blurry. However, some people may not observe any problem with their vision at a young age. If you have significant hyperopia, objects at any distance, far or near, can appear blurry.

  Presbyopia - This age-related condition affects your ability to focus on things closely. This happens because as you age, the lens of the eye is unable to change shape to allow the eye to focus on nearby objects clearly.

  Astigmatism - In this condition, the eye cannot focus light onto the retina evenly. As a result, images appear stretched out and blurry.

  Amblyopia or Lazy eye - This vision development disorder begins during early childhood and infancy. In this condition, the eye does not achieve normal visual acuity despite using contact lenses or prescribed glasses. Usually, amblyopia affects only one eye.

Can early diagnosis help treat the problem?

Yes, it can. Your eye care specialist can diagnose refractive errors and detect what exactly is impeding your vision with a comprehensive dilated eye examination. Upon encountering the symptoms mentioned above, one should consult an ophthalmologist at the earliest and get oneself checked.

If the condition is detected early, vision problems due to refractive errors can be treated. The common treatment options include the use of contact lenses, prescription glasses, and surgery (in severe cases).
People with visual problems should also adopt some lifestyle changes to correct their vision - eat more veggies, get adequate sleep and rest, abstain from smoking etc. Additionally, you should get periodic eye check-ups to monitor the condition.
