Comparing Glaucomatous Disc Change Using Stereo Disc Viewing and the MatchedFlicker Software Program in...

Area of Science:

• Ophthalmology
• Medical Technology

Background:

• Glaucoma diagnosis relies on detecting optic disc changes.
• Manual review of stereoscopic disc photographs is the traditional standard but can be time-consuming and subjective.

Purpose of the Study:

• To compare the diagnostic accuracy and efficiency of the MatchedFlicker software against manual stereoscopic viewing for evaluating glaucomatous optic disc changes.

Main Methods:

• A prospective study evaluated 140 image pairs from 100 patients using both handheld stereo viewers and MatchedFlicker software.
• Two resident ophthalmologists and one glaucoma fellow independently reviewed images, with accuracy and review time recorded.

Main Results:

• MatchedFlicker software achieved 87.6% accuracy, significantly higher than the 76.0% accuracy of stereo viewers (P = .011).
• Review time was faster with MatchedFlicker (24.9 seconds) compared to stereo viewers (34.1 seconds) (P = .044).
• MatchedFlicker demonstrated higher specificity and was particularly beneficial for less experienced trainees.

Conclusions:

• The MatchedFlicker software offers a more accurate and efficient method for assessing glaucomatous optic disc changes.
• This digital approach may enhance the diagnostic process for glaucoma progression.
