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 is a rare eye condition, experienced by Madeleine McCann, that can impact vision. ... "If there’s a coloboma of the eyelid, you can have surgery to repair that," Dr. Binenbaum says ...
[citation needed] Reconstruction of the lower eyelid coloboma includes the use of a myocutaneous flap, which is elevated and in this manner closes the eyelid defect. [39] External ear reconstruction is usually done when the individual is at least eight years old. Sometimes, the external auditory canal or middle ear can also be treated.
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 ]
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.
Patients can also suffer from hypoplasia of the mandible, cleft palate, lower eyelid coloboma, microtia, atresia of the ear canal, and hearing loss. [38] Treatments can include reconstructive surgeries of the eye, ear and zygomatic arch, orthodontics and hearing aids. [41]
Blepharophimosis forms a part of blepharophimosis, ptosis, epicanthus inversus syndrome (BPES), also called blepharophimosis syndrome, which is an autosomal dominant condition characterised by blepharophimosis, ptosis (upper eyelid drooping), epicanthus inversus (skin folds by the nasal bridge, more prominent lower than upper lid) and telecanthus (widening of the distance between the inner ...
