In a single study, the incidence of retinochoroidal coloboma was found to be 0.2 per 10,000. However, because retinochoroidal coloboma often causes no symptoms, it is likely that many cases go undiagonsed. Last updated: 1/14/201 Several presentation and associated clinical problems can be seen with retinochoroidal colobomas. We review five cases of retinochoroidal coloboma with no specific clinical problems and present five cases with clinical visual impairment

Retinochoroidal Coloboma is an eye abnormality that occurs before birth. It is characterized by missing pieces of tissue in both the retina (the light-sensitive tissue lining the back of the eye) and choroid (the blood vessel layer under the retina) In many cases, Retinochoroidal Coloboma does not cause symptoms Clinical features: Symptoms: depend on the location of the coloboma and ocular structures involved. Maybe associate with coloboma of other ocular structures along the embryonic fissure i.e. optic nerve, iris or lid. Choroidal neovascularization may develop at the margin of the coloboma. Associated with higher incidence of retina detachment

  1. The coloboma can involve multiple layers of the globe, including the iris, lens, nerve, retina and retinal pigment epithelium (RPE). Failure of RPE development in the area of the coloboma may lead to hypoplasia of the choroid and sclera, resulting in staphyloma, as seen in this case
  2. Retinal detachment and cataract are the most common complications associated with retinochoroidal coloboma. Coloboma of the posterior pole is associated with an increased risk for retinal detachment with occurs in 23-42% of patients. Iris coloboma with cataract. Zonular fibers are being seen through iris gap
  3. Combined optic nerve pits and retinochoroidal coloboma are a previously reported entity. They are believed to coexist because they originate from the same failure of fusion. As long as they are in the same eye, they are not known to carry increased risk of a systemic syndrome. References - Retina, 5th edition, Ryan et al.2013, Chapter 93.

  1. Coloboma is an eye abnormality that occurs before birth. Colobomas are missing pieces of tissue in structures that form the eye. They may appear as notches or gaps in one of several parts of the eye, including the colored part of the eye called the iris; the retina, which is the specialized light-sensitive tissue that lines the back of the eye; the blood vessel layer under the retina called.
  2. Reattachment was achieved after vitrectomy, peeling of epiretinal membranes, laser coagulation adjacent and temporal to the optic disc and gas endotamponade. Coincidence of this syndrome with an iris-retinochoroidal-coloboma is extremely rare. Both coloboma and optic disc pit are based on closure defects during week 6 of embryogenesis. PMID.
  3. Nonetheless, retinal detachment in the setting of retinochoroidal coloboma is a real risk with rates far surpassing the general population risk estimated at less than 1%. 16, 17. The surgical management of retinal detachment in eyes with coloboma is challenging

Retinochoroidal colobomas may cause choroidal neovascularization (CNV) and retinal detachment. The patient returned for visual field testing, which showed a superotemporal defect, correlating with the inferior optic disc coloboma. He was advised to follow up for yearly eye exams to monitor for early signs of CNV or retinal detachment Coloboma is a term derived from a Greek root, meaning mutilated or curtailed. 1 Optic nerve and retinochoroidal coloboma are caused by incomplete closure of the embryonic fissure during fetal development. 1 The incidence of coloboma is reported per 10,000 births to be 0.5 in Spain, 0.7 in France, and 0.75 in China. 2-4 When isolated, coloboma is most commonly sporadic and can be inherited in.

Retinochoroidal and optic nerve coloboma results from the abnormal closure of the embryonic fissure during weeks 5-7 of fetal life and may involve the iris, lens zonules, ciliary body, choroid, retina, and optic nerve.1, 2 They may be associated with serous retinal detachments, lenticonus, persistent hyaloid arteries, and optic disk pits. 2.

However, it can be present in non-myopic eyes, often acquired secondarily due to infection or trauma. Staphylomas that occur anteriorly are often acquired, while those that are posterior are.

Coloboma is an ocular birth defect resulting from abnormal development of the eye during embryogenesis. It is defined as a congenital defect in any ocular tissue, typically presenting as absent tissue or a gap, at a site consistent with aberrant closure of the optic fissure. Failure of fusion can lead to coloboma of one or multiple.
