Anterior segment indices in mentally retarded children

Area of Science:

• Ophthalmology
• Pediatrics
• Genetics

Background:

• Intellectual disability can impact overall health, including ocular development.
• Anterior segment parameters are crucial for eye health and refractive error assessment.
• Limited research exists on specific anterior segment indices in children with mental retardation.

Purpose of the Study:

• To compare anterior segment indices between mentally retarded and normal children.
• To investigate the association between mental retardation and specific corneal parameters.
• To identify potential risk factors for keratoconus in this population.

Main Methods:

• A cohort study involving 73 mentally retarded and 76 normal children.
• Psychological confirmation of mental retardation.
• Optometry examinations including visual acuity, refraction, and Pentacam corneal imaging.

Main Results:

• Significant associations were found between mental retardation and central corneal thickness (CCT), corneal diameter (CD), anterior chamber depth (ACD), and index of vertical asymmetry (IVA).
• Children with cerebral palsy exhibited higher keratoconus index (KI), central keratoconus index (CKI), index of height asymmetry (IHA), and index of height decentration (IHD).
• Moderate mental retardation was linked to higher ISV, IVA, IHA, and IHD compared to mild mental retardation.

Conclusions:

• Anterior segment indices differ significantly between mentally retarded and normal children.
• Children with cerebral palsy and more severe mental retardation show indicators associated with keratoconus.
• Routine keratoconus screening is recommended for children with mental retardation, particularly those with cerebral palsy or moderate to severe intellectual disability.
