Summary

Adults with intellectual disability (ID) often have vision problems like strabismus and refractive errors. Early eye exams are crucial for treating these conditions and improving quality of life.

Area of Science:

  • Ophthalmology
  • Genetics
  • Intellectual Disability Research

Background:

  • Intellectual disability (ID) is associated with various sensory impairments.
  • Ocular conditions are frequently observed in individuals with ID, impacting their overall well-being.

Purpose of the Study:

  • To document visual performance in adults with specific genetic causes of intellectual disability.
  • To compare these findings with existing literature.

Main Methods:

  • A large-scale, multicenter epidemiologic study involving 1598 adults with ID.
  • Ocular assessments were conducted on 1539 participants.
  • Data were analyzed for individuals with Angelman syndrome, Prader-Willi syndrome, fragile X syndrome, Williams-Beuren syndrome, and tuberous sclerosis.

Main Results:

  • An increased prevalence of strabismus, low vision, and refractive errors was identified.
  • Most syndrome groups, except fragile X and Prader-Willi, had individuals with visual impairment or blindness.
  • Some participants had no prior ophthalmological care.

Conclusions:

  • The study confirms known ocular features and suggests new ones in specific ID subgroups.
  • Treatable ophthalmological conditions are more frequent in these subgroups.
  • Feasible ocular assessments (85% success rate) encourage proactive eye care to enhance life quality for individuals with ID.
