Cataract is generally associated with old age. However, in some unfortunate cases, children could be affected by cataract as well. A cataract can be defined as a cloudy or opaque layer that forms on the eye's natural lens that lies behind the iris and the pupil, leading to eventual loss in vision. Cataract can affect children in one eye or both eyes.
Cataract can be a congenital birth defect or can develop as the child grows older. The latter case is known as pediatric cataracts. The exact cause of cataracts in children is not known, but it has been associated with a number of genetic disorders, low birth weight and infections during pregnancy. Traumatic events such as an injury to the eye can also cause cataracts.
The earlier a cataract is diagnosed and treated, the better it is. It is easier to identify a cataract that affects both eyes than a cataract that affects only one eye. If a congenital cataract is not treated in time, the part of the baby's brain used for sight may not develop properly. Hence it is crucial to recognize cataract symptoms.
Here are a few you should look out for:
- Not looking directly or responding to large, colourful objects.
- Not being able to find small objects while crawling.
- Excessive squinting or shielding their eyes to bright sunlight.
- Eyes that do not focus on the same point.
- White reflex instead of a red reflex in photographs.
- Uncontrolled movement of the eye.
Cataracts that are too small to affect sight can be treated with eye drops to dilate the pupil. However, this provides only temporary relief. Surgery is the most preferred form of cataract treatment. This surgery can be performed even in the first few weeks of a baby's life. The child is put under anesthesia and a microsurgical instrument is used to break the lens into small pieces and remove it.
This surgery is followed by the use of lenses or glasses to help the eye regain its power to focus again. In some cases, the lens may be implanted to replace the natural lens. In cases where cataract affects only one eye or one eye is more severely affected than the other, there may be a tendency to develop amblyopia or lazy eye syndrome. In such cases, it becomes necessary to patch the good eye shut and stimulate vision in the eye that has undergone surgery.
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:
- 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.
- 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.
