Fundus photos can diagnose cyclotropia by measuring the disc-fovea angle. This method identified extorsion and intorsion in normal individuals and patients with AV syndrome and superior oblique paresis.

Area of Science:

  • Ophthalmology
  • Ophthalmic Imaging
  • Strabismus Diagnosis

Context:

  • Cyclotropia diagnosis traditionally relies on clinical examination.
  • Fundus photography offers a potentially more objective method.
  • Assessing the disc-fovea angle is a novel approach.

Purpose:

  • To evaluate the utility of fundus photography in diagnosing cyclotropia.
  • To establish the disc-fovea angle as a diagnostic parameter.
  • To correlate fundus photo findings with specific strabismus patterns.

Summary:

  • The disc-fovea angle was measured from fundus photos in 40 normal individuals, averaging 7.43 degrees of extorsion.
  • Cyclotropia was diagnosed with extorsion >14.20 degrees, intorsion, or a disc-fovea angle difference ≥8 degrees between eyes.

  • Significant associations were found between V-pattern strabismus and excyclotropia, and A-pattern strabismus and incyclotropia.

    • Impact:

    • Fundus photography provides a basis for objective cyclotropia diagnosis.
    • This technique may aid in identifying and managing strabismus.
    • The findings support the integration of fundus imaging in clinical practice.
