Optometrists

Area of Science:

  • Ophthalmology and Optometry
  • Glaucoma Diagnosis
  • Optic Nerve Imaging

Background:

  • Accurate assessment of optic nerve head (ONH) features is crucial for glaucoma diagnosis.
  • Cup-to-disk (C/D) ratio estimation and identification of glaucomatous damage are key diagnostic steps.
  • Variability in ONH assessment among clinicians can impact patient care.

Purpose of the Study:

  • To evaluate agreement among optometrists in assessing optic nerve C/D ratios and glaucomatous damage.
  • To analyze how residency training, practice setting, and glaucoma patient experience influence these assessments.
  • To determine interobserver and intraobserver agreement levels.

Main Methods:

  • Fifty-six optometrists evaluated 33 stereoscopic optic nerve photographs.

  • Participants estimated vertical C/D ratios and determined glaucomatous status.
  • Interobserver and intraobserver agreement were calculated using kappa statistics.

    • Main Results:

    • Optometrists' C/D ratio estimations and glaucoma damage interpretations varied significantly based on training, practice setting, and experience.
    • Higher interobserver agreement for C/D ratios and glaucomatous damage was observed among residency-trained optometrists and those in clinical settings.
    • Agreement was notably higher for optometrists with residency training and those practicing in clinical settings (e.g., optometry schools, medical centers).

    Conclusions:

    • Intraobserver agreement exceeded interobserver agreement for both C/D ratio estimation and glaucomatous damage assessment.
    • Residency training, practice environment, and the volume of glaucoma patient encounters significantly influence optometrists' optic nerve evaluations.
    • Standardization of ONH assessment criteria may be beneficial to improve diagnostic consistency.
