Comparison of Glaucoma Detection Performance of Binocular Perimetry Screening Program Using imo Perimetry With...

Area of Science:

• Ophthalmology
• Medical Devices
• Diagnostic Accuracy

Background:

• Glaucoma detection relies on accurate visual field testing.
• Frequency doubling technology (FDT) is an established screening tool.
• Novel screening methods are needed to improve efficiency and accessibility.

Purpose of the Study:

• To compare the glaucoma detection accuracy of the "imo" screening program (ISP) with frequency doubling technology (FDT).
• To evaluate the testing time efficiency of ISP versus FDT.

Main Methods:

• A multicenter diagnostic accuracy study prospectively collected data from 76 non-glaucoma and 92 glaucomatous eyes.
• Patients underwent both ISP and FDT (C-20-1 screening program) on the same day.
• Diagnostic efficacy was assessed using receiver operating characteristic curves and areas under the curve (AUCs).

Main Results:

• ISP showed non-inferiority to FDT across all glaucoma stages (mild, moderate, advanced).
• AUC values for mild-stage glaucoma were 0.82 for ISP vs. 0.76 for FDT.
• ISP demonstrated significantly shorter testing times than FDT for all glaucoma stages (P < 0.001).

Conclusions:

• The ISP is a non-inferior and more time-efficient method for glaucoma detection compared to FDT.
• These findings support the use of ISP in large-scale population-based glaucoma screening programs.
