Vision assessment in persons with intellectual disabilities.

Area of Science:

• Ophthalmology
• Intellectual Disabilities Research
• Occupational Health

Background:

• Intellectual disabilities can affect an individual's awareness of health issues, including vision.
• Limited research exists on the visual acuity and eye care needs of workers with intellectual disabilities.

Purpose of the Study:

• To assess visual acuity in workers with intellectual disabilities.
• To determine the impact of vision deficits on their working conditions.
• To evaluate the need for regular eye care in this population.

Main Methods:

• A vision examination program was conducted with 224 workers with intellectual disabilities.
• Assessments included visual acuity, refraction, ocular motility, and color perception.
• Participants with vision deficits were provided with spectacles.

Main Results:

• A significant proportion of participants had uncorrected vision deficits, with low visual acuity for both near and far vision.
• Many workers, especially those aged 50 and above, lacked appropriate eyewear for near tasks.
• Following correction, best-corrected visual acuity improved significantly (p < 0.001).

Conclusions:

• Workers with intellectual disabilities often lack awareness of their visual impairments.
• Appropriate optical correction can address many visual abnormalities.
• Regular eye care and vision screening are crucial for this population to improve their quality of life and work performance.
