Vision Screening in Infants Attending Immunization Clinics in a Developing Country

Area of Science:

• Ophthalmology
• Pediatrics
• Public Health

Background:

• Infant vision screening is vital for early detection of eye conditions.
• Untreated ocular anomalies in infancy can lead to permanent vision impairment.
• Prompt intervention is critical to prevent irreversible vision loss.

Purpose of the Study:

• To determine the prevalence of ocular anomalies in Nigerian infants.
• To assess the utility of immunization clinics for infant vision screening.
• To facilitate timely referral and treatment of identified eye conditions.

Main Methods:

• Cross-sectional, descriptive study involving 142 infants across 6 immunization clinics.
• Screening included ocular history, vision assessment, external examination, and red reflex testing.
• Infants with abnormalities or risk factors were referred for comprehensive eye exams.

Main Results:

• A 15.5% prevalence of ocular abnormalities was found in screened infants.
• Common conditions included neonatal conjunctivitis (38%), strabismus (14%), and nasolacrimal duct obstruction (14%).
• Prematurity was a significant risk factor identified in referred infants.

Conclusions:

• Immunization clinics are effective sites for infant vision screening in developing countries.
• Conjunctivitis, strabismus, and nasolacrimal duct obstruction are prevalent infant eye disorders.
• Screening can identify infants at risk for conditions like retinopathy of prematurity.
