Summary

Thalidomide toxicity can cause nonprogressive corneal endothelial changes resembling cornea guttata. These ocular findings may stem from thalidomide affecting neural crest cell development, impacting corneal endothelium and stroma.

Area of Science:

  • Ophthalmology
  • Teratology
  • Developmental Biology

Background:

  • Thalidomide is a known teratogen associated with limb defects.
  • Ocular manifestations of thalidomide toxicity are not well-documented.

Observation:

  • A 30-year-old male with thalidomide-induced phocomelia presented with bilateral symmetrical corneal changes.
  • The changes resembled cornea guttata but without edema.
  • Advanced imaging (pachymetry, specular, confocal microscopy) was utilized.

Findings:

  • Bilateral, nonprogressive corneal endothelial abnormalities were observed.
  • Corneal guttata-like changes persisted over a 10-year follow-up without edema.
  • No significant changes in corneal thickness or endothelial cell morphology were noted during the follow-up.

Implications:

  • Corneal endothelial changes may be an underrecognized ocular manifestation of thalidomide toxicity.
  • Thalidomide's teratogenic effects might impact neural crest cell development, crucial for corneal endothelium formation.
  • This case highlights the importance of comprehensive ocular examination in individuals exposed to thalidomide.
