    Summary
    This summary is machine-generated.

    Genetic factors are the primary cause of vision defects in Kuwaiti students, accounting for 75.5% of cases. Inflammatory conditions, often due to neglected conjunctivitis, are also a significant factor.

    Area of Science:

    • Ophthalmology
    • Genetics
    • Public Health

    Background:

    • Defective vision poses a significant public health concern among student populations.
    • Understanding the etiological factors is crucial for developing targeted interventions.

    Purpose of the Study:

    • To investigate the primary causes of defective vision in a large cohort of Kuwaiti students.
    • To analyze the contribution of genetic, inflammatory, and other factors to vision impairment.

    Main Methods:

    • A cross-sectional study analyzing data from 139,769 Kuwaiti students.
    • Categorization of defective vision causes into hereditary/genetic, inflammatory, traumatic, metabolic, and neoplastic.
    • Sub-analysis of genetic inheritance patterns and the role of consanguineous marriages.

    Main Results:

    • The prevalence of defective vision was 0.099% among the studied students.
    • Hereditary and genetic factors accounted for 75.5% of cases, with recessive inheritance (36.2%) and autosomal dominant (34.3%) being most common.
    • Consanguineous marriages contributed to 46.7% of hereditary cases.
    • Inflammatory causes represented 20.9%, primarily from neglected conjunctivitis leading to corneal ulcers (62.1% of inflammatory cases).
    • Traumatic, metabolic, and neoplastic causes constituted 3.6%.

    Conclusions:

    • Genetic and hereditary factors are the predominant causes of defective vision in Kuwaiti students.
    • The high incidence of consanguinity-related genetic defects highlights a need for genetic counseling.
    • Preventable inflammatory causes, particularly neglected conjunctivitis, underscore the importance of timely medical attention and public health education.
