A rare vertical accommodative vergence was observed in three patients. This vertical eye deviation, linked to focusing, appeared after vision loss, suggesting a congenital abnormality.

Area of Science:

  • Ophthalmology
  • Neuro-ophthalmology
  • Strabismology

Background:

  • Vertical accommodative vergence is a rare vergence disorder.
  • Accommodative vergence links focusing effort to eye alignment.
  • Understanding its pathophysiology is crucial for diagnosing and managing strabismus.

Observation:

  • Three cases of vertical accommodative vergence were identified.
  • One patient developed this vergence after unilateral blindness due to trauma.
  • The affected eye showed upward deviation during desaccommodation and downward deviation during accommodation.

Findings:

  • The vertical vergence was triggered by accommodation.
  • This phenomenon was not present before the loss of binocular vision.
  • The findings suggest a potential congenital supranuclear abnormality.

Implications:

  • The study highlights a novel presentation of vertical accommodative vergence.
  • It suggests that loss of binocular vision can unmask latent neurological conditions.
  • Further research is needed to elucidate the underlying mechanisms and clinical significance.
