Summary

Duane's retraction syndrome (DRS) can be inherited. This study identified a family with three members affected by DRS, suggesting an autosomal dominant inheritance pattern for this rare congenital eye condition.

Area of Science:

  • Ophthalmology
  • Genetics
  • Pediatric Neurology

Background:

  • Duane's retraction syndrome (DRS) is a congenital eye movement disorder.
  • While often sporadic, familial cases of DRS indicate a genetic component.

Observation:

  • A Romanian family presented with three affected members exhibiting DRS.
  • The affected individuals displayed classic signs of unilateral DRS affecting the left eye.

Findings:

  • Key findings included left esotropia in primary gaze and impaired left eye abduction.
  • Associated signs were anomalous head posture, eyelid fissure narrowing, and globe retraction on adduction.

Implications:

  • This case provides further evidence for autosomal dominant inheritance in some DRS cases.
  • Understanding the genetic basis of DRS is crucial for genetic counseling and family studies.
