Interrater agreement in oculo-kinetic perimetry--a screening test for glaucoma
1Department of Ophthalmology, Royal Adelaide Hospital, South Australia.
Summary
Oculo-kinetic perimetry shows excellent agreement among examiners for glaucoma screening. However, a high false-negative rate requires further investigation before widespread clinical adoption.
Area of Science:
- Ophthalmology
- Medical Diagnostics
Background:
- Glaucoma is a leading cause of irreversible blindness.
- Early detection through screening is crucial for managing glaucoma.
- Oculo-kinetic perimetry is a potential screening tool for glaucoma.
Purpose of the Study:
- To evaluate the interrater reliability of oculo-kinetic perimetry in glaucoma screening.
- To assess the accuracy and feasibility of oculo-kinetic perimetry in a clinical setting.
Main Methods:
- Twenty-four glaucomatous eyes with known field defects were tested.
- Three examiners with diverse backgrounds utilized oculo-kinetic perimetry.
- Interrater agreement and test results were recorded.
Main Results:
- Excellent interrater agreement was observed, with only one discrepancy among examiners.
- Seventeen eyes showed defective results, while six yielded normal findings.
- The test was found to be easy for patients and untrained staff to perform.
Conclusions:
- Oculo-kinetic perimetry demonstrates high reliability among clinicians for glaucoma screening.
- A significant false-negative rate necessitates further evaluation of the test's sensitivity.
- Consideration for its use as a complementary tool for opticians and general practitioners is suggested.
