Summary
This study compared glaucoma diagnostic methods, finding no superior alternatives to standard white-white perimetry. Emerging temporal techniques show promise for future glaucoma diagnosis and follow-up.
Area of Science:
- Ophthalmology
- Medical Diagnostics
Background:
- Glaucoma diagnosis and follow-up rely on various imaging and functional tests.
- Accurate early detection is crucial for preventing vision loss.
Purpose of the Study:
- To compare the diagnostic and follow-up capabilities of different glaucoma assessment methods.
- Evaluate the sensitivity and specificity of emerging and established techniques.
Main Methods:
- Systematic review of published sensitivity and specificity data.
- Analysis of comparative studies, particularly in early-stage glaucoma patients.
Main Results:
- No evidence suggests blue-yellow perimetry (SWAP), nerve fiber photography, laser polarimetry (GDx), electrophysiological tests, or optic nerve head topography outperform white-white perimetry.
- White-white perimetry demonstrates evolving precision with new criteria.
- Discrepancies exist between anatomical and functional assessment results, preventing definitive conclusions.
Conclusions:
- Temporal phenomena (FDT, Flicker, PULSAR), advanced optic nerve topography analysis, and loss variance (LV) in TOP perimetry are promising for future glaucoma management.
- Blue-yellow perimetry and GDx showed poorer diagnostic performance.
