Aniridia - Ptosis - Mental Retardation - Obesity, Familial refers to a form of intellectual disability that is characterized mainly by absent irises (colored section) in the eyes, drooping of the eyelids, below-average mental ability, and excess body weight. Hence, individuals with this form of intellectual disability have severe vision problems. 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 often diagnosed during childhood. Doctors diagnose this form of intellectual disability if eye problems and excess body weight 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 developed on a case-by-case basis and depends on the specific needs of the patient. Eye specialists may suggest patients undergo surgery to repair iris and eyelid problems. Doctors may also create exercise plans to help individuals lose excess body weight. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
