    Summary

    Marfan's syndrome (MS) patients often have abnormal electroretinography (ERG) results, indicating visual function defects. These electrophysiological tests reveal potential eye complications in individuals with this inherited connective tissue disorder.

    Area of Science:

    • Ophthalmology
    • Genetics
    • Clinical Electrophysiology

    Background:

    • Marfan's syndrome (MS) is a genetic disorder affecting connective tissue.
    • Ocular manifestations are common in MS, including lens dislocation, myopia, and retinal detachment.

    Observation:

    • Eleven patients with Marfan's syndrome were evaluated using electroretinography (ERG).
    • ERG assesses the electrical response of the retina to light, providing insights into visual function.

    Findings:

    • Six out of eleven MS patients exhibited normal ERG results.
    • Five MS patients presented with abnormal ERG findings.
    • Specific visual impairments noted included retinal detachment (1 case), myopia (3 cases), and secondary glaucoma (1 case).

    Implications:

    • Electrophysiological testing, such as ERG, can detect subclinical visual function deficits in Marfan's syndrome.
    • Early identification of visual impairments may facilitate timely intervention and management of ocular complications in MS patients.
