Mental Retardation - coloboma - slimness refers to a form of intellectual disability that is characterized mainly by below-average mental ability, vision problems, and a slim build. Individuals with this form of intellectual disability often cannot see objects in certain areas of their visual field. Like other individuals with intellectual disability, an individual with this condition often has problems with reasoning and solving problems, as well as performing day-to-day tasks. The condition is also often diagnosed during childhood. Doctors diagnose this form of intellectual disability if a slim frame and visual field problems are observed. Signs like walking and talking late, slow mastering of basic tasks, and having difficulty remembering things may also suggest this condition in children. Treatment is based on a case-by-case basis and depends on the specific needs of the patient. Eye specialists can provide treatment for the visual field problems. Specialized contact lenses and glasses can be used to help with the vision problems. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
