A coloboma in the eye is known as the region where tissue is missing. A person’s eye has colobomas when they are born. One or both of your eyes may be affected.
The colobomas that are most well-known and frequent impact the iris (the colored tissue of the eye) and give your pupil a keyhole appearance. Colobomas come in a variety of forms, the majority of which are not visible from the outside.
While some colobomas have no symptoms, others may negatively affect vision. Depending on where the coloboma grew in the eye and the type of tissue that is missing, different people will have different symptoms.
When a child is born, your doctor might be able to make a coloboma diagnosis. A coloboma can occur in anyone at birth. They fall under the category of genetic disorders, which means that parents can pass them on to their offspring. They might be described as a congenital disorder. However, even if one parent (or both) have colobomas, it does not necessarily follow that your child will as well.
Every year, about 1 in 10,000 newborns are born with colobomas. That number may be higher because not all colobomas result in observable symptoms. Some patients with undetected colobomas never experience any symptoms or side effects. The position of the coloboma in your child’s eye will determine how much it affects them. Colobomas may appear in both eyes or just one (unilateral coloboma) (bilateral coloboma). Different areas of the eyes may be affected by bilateral colobomas.
Nearly every component of your child’s eye, including the iris, retina, optic nerve, macula, ciliary body, and eyelid, is susceptible to colobomas.
Your child’s vision may not be affected by some colobomas.f your child has a coloboma on their retina, macula or optic nerve they might have some vision, but it might be impaired Others render the damaged eye completely blind.
When a child has a coloboma, especially when they are very young, you might not immediately realise how it is affecting their eyesight.
Colobomas may increase a person’s risk of developing other eye conditions later in life, such as cataracts, glaucoma, and retinal detachment.
Low vision, a keyhole or cat-eye-shaped pupil, blindness or partial vision loss, light sensitivity, and nystagmus are just a few of the coloboma symptoms that may affect your child.
Only a section of your child’s field of vision may be affected by a coloboma (the full range of how much they can see). Reduced peripheral vision is one of the effects of colobomas. Having trouble seeing in depth and having a bigger blind spot than usual.
According to experts, colobomas are brought on by a hereditary condition that impairs a baby’s growing eyes throughout pregnancy.
