Preoperative workup Cataract often develops at a younger age in patients with colobomatous lenses. The extent of the ocular structures affected by the coloboma should be determined preoperatively. [healio.com]

Another option might be a topography-driven customized treatment. This approach is still complicated by the presence of an iris defect outside the treatment zone, and it is unclear exactly how to center such a treatment. [crstoday.com]

Symptoms and treatment The iris controls the amount of light entering the eye by adjusting the size of the pupil through two muscles. When the iris is defective, it can no longer perform this control function. [optik-akademie.com]

Prognosis[9] The prognosis for vision depends on the severity and location of the coloboma (particularly in relation to the optic nerve, macula and maculopapular bundle) and on any complications such as retinal detachment or amblyopia. [patient.info]

Prognosis The prognosis for vision depended on the phenotype of the better eye  Microphthalmos with cyst has the worst prognosis  Coloboma with microcornea and microphthalmos a poor prognosis  Coloboma with only microcornea has an intermediate prognosis [slideshare.net]

Prognosis Local recurrence common; many metastasise; 5-year survival reflects stage when diagnosed. [medical-dictionary.thefreedictionary.com]

Diagnosis and Prognosis: The diagnosis is usually made by an ophthalmologist. It is important to have a complete eye and physical examination to determine if other anomalies or conditions are present. [disorders.eyes.arizona.edu]

Vision can be improved with glasses, contact lenses or even laser eye surgery but may be limited if the retina is affected or there is amblyopia.[5] Epidemiology[edit] The number of cases is around 5 to 7 per 100,000 births, making it a relatively rare [en.wikipedia.org]

Epidemiology[1] The estimated incidence of coloboma is about 1 in 10,000 births. Coloboma is estimated to account for 3-11% of blindness in children worldwide. Aetiology[2] The eye develops in the embryo, from the optic cup and optic fissure. [patient.info]
