To investigate the value of Cirrus spectral domain optical coherence tomography (SD-OCT)-guided progression analysis (GPA) to detect glaucoma progression, and to find factors associated with the diagnostic accuracy of SD-CT GPA assessment.
This retrospective study included 68 eyes of 68 glaucoma patients. All patients underwent SD-OCT measurements more than 3 times with 6-month intervals. Glaucoma progression was assessed using SD-OCT GPA software. Conventional glaucoma progression assessment was also performed using a red-free retinal nerve fiber layer photography and Humphrey visual field test (HVF).
The mean age of subjects was 57.4 ± 12.4 years old and the mean follow-up period was 49.4 ± 25.1 months. Of the 68 eyes, 28 eyes (41.2%) showed glaucoma progression based on conventional assessment, while 32 eyes (47.1%) showed progression based on SD-OCT GPA assessment. Using the conventional method as a gold standard for the detection of glaucoma progression, the false-positive rate and the false-negative rate were 60.7% and 52.5%, retrospectively, for SD-OCT GPA assessment. Factors associated with false-positive and false-negative results were signal strength of less than 6 on multivariate logistic regression analysis (P = 0.014 and P = 0.023, respectively).
In patients with glaucoma, it seems insufficient to determine the disease progression using the SD-OCT GPA assessment only, especially in cases with low signal strength.
