Summary

This study reports the first case of Alagille syndrome (AGS) with optic pit and serous macular detachment. This rare combination highlights potential neurodevelopmental links in AGS patients.

Area of Science:

  • Ophthalmology
  • Genetics
  • Developmental Biology

Background:

  • Alagille syndrome (AGS) is a genetic disorder that can affect multiple organs, including the eyes.
  • Optic disc anomalies are known complications of AGS.
  • This report details a unique case associating AGS with specific ocular findings.

Observation:

  • A male patient diagnosed with Alagille syndrome presented with decreased vision in one eye.
  • Ocular examination revealed posterior embryotoxon and optic pit.
  • Serous macular detachment was also identified in the affected eye.

Findings:

  • Optical Coherence Tomography (OCT) confirmed the presence of optic pit and serous macular detachment.
  • The combination of Alagille syndrome, optic pit, and serous macular detachment is unprecedented in medical literature.

Implications:

  • The co-occurrence suggests a possible shared genetic pathway or developmental defect affecting neuroectodermal development in AGS.
  • Optic pits warrant further investigation for underlying genetic or developmental abnormalities, especially in patients with systemic syndromes.
  • This case expands the known spectrum of ocular manifestations in Alagille syndrome.
