Sequential MD rates of change were estimated with each series spanning only 5 years of follow-up. VF progression was declared when four sequential statistically significant negative MD slopes were observed, and slope for the entire follow-up was significant. A convolutional neural network pretrained on ImageNet was designed to predict VF progression using baseline clinical and demographic data, disc photographs, and optical coherence tomography-derived global and sectoral retinal nerve fiber layer and macular thickness measurements. In addition, average intraocular pressure and treatment information during follow-up were put into the model. The same data for a subset of patients was provided to two clinicians to independently predict future progression. The model was validated on a separate cohort of eyes in which optical coherence tomography imaging was done with a different device (291 eyes).</div></div><div><h3>Main Outcome Measures</h3><div>Model’s area under receiver operating characteristic curves (AUC), accuracy, and area under the precision and recall curves.</div></div><div><h3>Results</h3><div>Average (SD) baseline MD and number of VF exams were −3.5 (4.9) dB and 10.1 (4.7). 399 eyes (25%) deteriorated.
