       Coloboma is a congenital eye condition that results from abnormal development during fetal growth. It is a rare condition that occurs in about 1 in 10,000 births. Coloboma can affect one or both eyes and can cause a range of visual impairments.

        Coloboma is a condition that affects the eye's structure and can occur in any part of the eye, including the iris, retina, choroid, and optic disc. It is caused by the failure of the eye to develop normally during fetal growth. Coloboma can range from a small, harmless notch in the iris to a large, sight-threatening hole that affects multiple structures in the eye.

        The symptoms of coloboma can vary depending on the size and location of the abnormality. Common symptoms include: Poor vision or vision loss, Sensitivity to light, Nystagmus (involuntary eye movement), Strabismus (misaligned eyes), Abnormal pupil shape or size, Cataracts (clouding of the eye's lens).

          Coloboma is a genetic condition that is inherited in an autosomal dominant or recessive pattern. It can also occur spontaneously without any family history. Several genes have been identified as playing a role in coloboma, including PAX2, CHD7, and SOX2.

          There is no cure for coloboma, and treatment depends on the severity of the condition and the location of the defect. Some people with coloboma may have no visual impairments and require no treatment. Others may require corrective lenses, patching, or surgery to improve vision or correct misaligned eyes. In severe cases, vision may not be correctable, and the person may be classified as legally blind.

           Coloboma is a rare congenital condition that can affect any part of the eye and can cause a range of visual impairments. It is caused by abnormal development during fetal growth and can be inherited in an autosomal dominant or recessive pattern. Treatment depends on the severity of the condition and may include corrective lenses, patching, or surgery. While there is no cure for coloboma, early diagnosis and intervention can help improve outcomes.
