Comparing glaucomatous disc change using stereo disc viewing and the MatchedFlicker programme in glaucoma experts and...

Area of Science:

• Ophthalmology
• Medical Imaging
• Glaucoma Diagnosis

Background:

• Glaucomatous optic disc change detection is crucial for timely intervention.
• Manual examination of stereoscopic disc photographs is a standard but time-consuming method.
• Evaluating new tools to enhance diagnostic efficiency is essential.

Purpose of the Study:

• To compare the accuracy and speed of MatchedFlicker software versus manual stereoscopic viewing for glaucoma detection.
• To assess performance differences between trainees and experienced glaucoma specialists.

Main Methods:

• 140 image pairs from 100 eyes were evaluated by glaucoma specialists and trainees.
• Evaluators used both a handheld stereo viewer and MatchedFlicker software.
• Accuracy and evaluation time were measured for each method.

Main Results:

• MatchedFlicker software was 26% faster per image pair (p=0.0007) and improved accuracy (p=0.0003).
• No significant speed or accuracy differences were found between expert and trainee groups.
• Experts showed higher consistency with duplicate images (p=0.029), while trainees were more conservative in diagnosing progression.

Conclusions:

• MatchedFlicker software offers superior accuracy and speed for glaucoma diagnosis compared to traditional stereoscopic viewers.
• The software benefits both experienced specialists and trainees in ophthalmology.
• Digital tools can enhance the efficiency of glaucoma detection.
