Summary

Three methods for measuring cyclotorsion (eye rotation) yielded different results, but all were repeatable over time. Clinicians should consider these differences when monitoring patients or planning surgical correction for cyclotorsion.

Area of Science:

  • Ophthalmology
  • Orthoptics
  • Vision Science

Background:

  • Cyclotorsion, a rotational eye deviation, can impact visual function.
  • Accurate measurement of cyclotorsion is crucial for diagnosis and treatment planning.
  • Standardized and reliable methods for assessing cyclotorsion are needed in clinical practice.

Purpose of the Study:

  • To compare the results of three different subjective cyclotorsion measurement methods.
  • To assess the repeatability of each cyclotorsion measurement method over time.

Main Methods:

  • Twenty patients with vertical deviation underwent subjective cyclotorsion measurements.
  • Three methods were used: synoptophore, single Maddox rod test (SMR), and KMScreen.
  • Measurements were repeated three times per eye and on two separate occasions to assess repeatability.

Main Results:

  • Significant differences were found between the synoptophore and SMR, and between the SMR and KMScreen methods.
  • All three methods demonstrated significant repeatability (test-retest reliability).
  • Prevalence of excyclotorsion varied across methods, with SMR identifying it most frequently.

Conclusions:

  • Different subjective cyclotorsion measurement methods produce significantly different results.
  • Despite inter-method variability, all tested methods exhibit good test-retest reliability.
  • Awareness of method-specific differences is critical for accurate patient monitoring and surgical planning for cyclotorsion.
