This study examined 46 individuals with intellectual disabilities, finding a high prevalence of vision problems including refractive errors like hyperopia and myopia, and strabismus. These ocular conditions require attention in managing the overall health of individuals with cognitive impairments.

Area of Science:

Ophthalmology
Genetics
Neurology

Background:

Intellectual disability is associated with various genetic syndromes and neurological conditions.
Ocular health is a critical, yet often overlooked, aspect of comprehensive care for individuals with intellectual disabilities.
Previous literature highlights diverse neurological and syndromic alterations in this population.

Purpose of the Study:

To document the general and ocular characteristics of individuals with intellectual disabilities receiving visual care.
To identify the prevalence of specific ocular conditions within a cohort of 46 patients.
To correlate syndromic and neurological diagnoses with observed ophthalmological findings.

Main Methods:

Retrospective analysis of 46 patients with intellectual disabilities who underwent ophthalmological examinations.

Categorization of patients based on diagnosis: genetic syndromes (Down's, Soto, West, Rubinstein-Taybi, Triple X) and neurological conditions (cerebral palsy, microcephaly, hydrocephaly).

Detailed recording of general characteristics (IQ, age) and ocular findings, including refractive errors and strabismus.

Main Results:

High incidence of ametropias was observed: 58.7% hyperopia, 21.7% myopia, and 19.5% astigmatism.
Strabismus was present in 28% of the study group.
Down's syndrome was the most frequent diagnosis (25 out of 46 patients).

Conclusions:

Individuals with intellectual disabilities exhibit a significant burden of ocular conditions, particularly refractive errors and strabismus.
Regular and specialized visual care is essential for this population to address prevalent ophthalmological issues.
Further research is warranted to understand the specific etiological links between different syndromes/neurological conditions and ocular manifestations.
