    This case study details a child with congenital glaucoma, emphasizing extrinsic factors like maternal infections during pregnancy as potential causes. Surgical intervention showed positive outcomes, highlighting the importance of identifying teratogenic influences.

    Area of Science:

    • Ophthalmology
    • Pediatric Ophthalmology
    • Genetics

    Background:

    • Congenital glaucoma is a rare condition affecting infants, characterized by increased intraocular pressure and potential vision loss.
    • Phenocopy refers to traits that mimic genetic conditions but are caused by environmental factors.
    • Understanding the etiology of congenital glaucoma is crucial for early diagnosis and effective management.

    Observation:

    • A 6-year-old child presented with right eye congenital glaucoma, ocular globe enlargement, Descemet's membrane ruptures, and divergent strabismus.
    • The left eye exhibited microphthalmos with a 9 mm corneal diameter.
    • The patient had a normal karyotype, suggesting a non-genetic origin for the observed condition.

    Findings:

    • The right eye underwent trabeculectomy with a favorable postsurgical outcome.

  • The condition was identified as a phenocopy, likely resulting from extrinsic teratogenic factors during the sixth month of pregnancy.
  • Maternal exposure to measles, influenza, and toxemia during pregnancy were implicated as potential causes for iridocorneal angle developmental anomalies.

    • Implications:

    • This case underscores the significance of environmental influences, such as maternal infections and pregnancy complications, in the development of congenital glaucoma.
    • Identifying teratogenic factors can aid in preventing similar conditions and improving prenatal counseling.
    • Successful surgical management of congenital glaucoma, even in complex cases, offers hope for preserving vision.
