What is Choroidal Coloboma?
Choroidal Coloboma is a congenital eye disorder that affects the structure of the eye. It is characterized by a missing piece in the choroid layer, which is responsible for nourishing the retina and maintaining visual function. This condition occurs during fetal development when the eye fails to form properly, resulting in a gap or defect in the choroid.
The impact of Choroidal Coloboma on vision can vary depending on the size and location of the missing tissue. In some cases, the visual impairment may be minimal, while in others, it can lead to significant vision loss or other associated eye abnormalities.
To visually understand the impact of Choroidal Coloboma, refer to the table below:
| Severity Levels | Vision | Associated Eye Abnormalities |
|---|---|---|
| Mild | Slight visual disturbances | None |
| Moderate | Impaired depth perception, reduced visual acuity | Strabismus (crossed eyes), nystagmus (involuntary eye movement) |
| Severe | Profound vision loss | Retinal detachment, cataracts, glaucoma |
The presence of Choroidal Coloboma can be diagnosed through a comprehensive eye examination, including a careful evaluation of the retina and choroid. Additional diagnostic tests, such as optical coherence tomography (OCT) and fluorescein angiography, may be used to assess the extent of the coloboma and its impact on retinal function.
It’s important for individuals with Choroidal Coloboma to work closely with their eye care professionals to understand their specific visual challenges and develop a personalized care plan.
