A coloboma (from the Greek κολόβωμα, meaning "defect") [1] is a hole in one of the structures of the eye, such as the iris, retina, choroid, or optic disc.The hole is present from birth and can be caused when a gap called the choroid fissure, which is present during early stages of prenatal development, fails to close up completely before a child is born.
The coloboma which occurs often in facial clefts is a cleft in the lower or upper eyelid. This should be closed as soon as possible, to prevent drought of the eye and a consecutive loss of vision. [ 24 ]
Coloboma of optic nerve is a rare defect of the optic nerve that causes moderate to severe visual field defects. Coloboma of the optic nerve is a congenital anomaly of the optic disc in which there is a defect of the inferior aspect of the optic nerve. The issue stems from incomplete closure of the embryonic fissure while in utero.
Coloboma is when part of the eye tissue is missing, which can lead to vision loss and sensitivity to light. Strabismus most commonly occurs in infants and young children, but adults can also ...
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.
Coloboma of the eye is visible in the retina as "hole" in its structure, and causes low vision, possible sensitivity to light and variance in size of the eyeball. [ 11 ] [ 12 ] The build-up of tissue in the liver, known as hepatic fibrosis , may cause symptoms such as jaundice , ascites , abnormal bleeding and enlarged spleen. [ 12 ]
A coloboma is the failure to close the choroid fissure, which is the opening from the ventral side of the retina in the optic stalk. [5] Despite the similarities with coloboma and morning glory anomaly, significant differences exist such that optic disc dysplasia cannot be classified as either one entity. [ 6 ]
