Filter by:The investigators are inviting families to take part in a research study that will help us better understand the physical characteristics associated with children who have Microphthalmia, Anophthalmia, and Coloboma (MAC) and how changes in their DNA sequence, called genetic mutations, play a role in the risk of developing MAC
Congenital malformations of the eye comprise various developmental defects including microphthalmia, anophthalmia, aniridia, and anterior segment anomalies (such as Peters and Axenfeld-Rieger anomalies). These malformations are frequently associated with extra-ocular features and intellectual disability. However, little is known about visual outcome, frequency and consequences of extra-ocular features in patients. The originality of the project will be to include a spectrum of malformation thought to be a phenotypic continuum (anophthalmia, microphthalmia, aniridia, anterior segment dysgnesis). In addition, we aim to conduct a 10 year follow-up of these children, thus allowing determining ocular and neurological outcomes as any other medical event. We should also be able to determine phenotypic factors that would be associated with good or poor visual and neurologic outcomes
This study will evaluate the effect of posterior placement of orbital implants on their motility compared to intrascleral placement after evisceration .
Understand better the aetiology and physiopathogenesis of anophthalmic socket syndrome.
Background: - Uveal coloboma is a condition where the eye does not form normally. It occurs early in the fetus s development during pregnancy. It can lead to different kinds of eye problems, including blindness. Several genes have been linked to coloboma, but the cause of most cases is hard to find. Researchers want to study the genes of people who have coloboma and genes from their close, unaffected relatives (such as parents and siblings). Objectives: - To study the genes associated with uveal coloboma. Eligibility: - Individuals at least 1 years of age who either have uveal coloboma or are an unaffected relative (such as a parent or sibling). Design: - Participants will have a physical exam and medical history. They will also have a full eye exam. - Participants with uveal coloboma may have other exams, such as imaging studies and hearing assessments. - All participants will also provide blood, cheek swab or saliva or DNA samples for genetic testing.
