    Summary

    Congenital infantile glaucoma, or hydrophthalmia, causes early electro-retinogram changes in children. These findings indicate severe retinal and optic nerve damage, necessitating surgical intervention.

    Area of Science:

    • Ophthalmology
    • Pediatric Medicine
    • Clinical Electrophysiology

    Background:

    • Congenital infantile glaucoma (hydrophthalmia) is a rare but severe form of pediatric glaucoma.
    • Early diagnosis and intervention are crucial for preserving vision in affected children.

    Purpose of the Study:

    • To investigate the electrophysiological characteristics of congenital infantile glaucoma in children.
    • To differentiate the electrophysiological profile of infantile glaucoma from adult glaucoma.

    Main Methods:

    • Electrophysiological examination of 38 children diagnosed with congenital infantile glaucoma (hydrophthalmia).
    • Assessment included electro-retinogram (ERG) and electrical phosphene threshold measurements.

    Main Results:

    • Hydrophthalmia demonstrated early alterations in the electro-retinogram (ERG).
    • A significant rise in the electrical phosphene threshold was observed.
    • These electrophysiological changes suggest profound pathological alterations in the optic nerve and retina.

    Conclusions:

    • Electrophysiological testing reveals distinct and early changes in infantile glaucoma compared to adult forms.
    • The observed electrophysiological abnormalities underscore the severity of retinal and optic nerve involvement.
    • Prompt surgical intervention is indicated for children diagnosed with hydrophthalmia based on these findings.
