The advent of optical coherence tomography (OCT) has enabled the evaluation of novel optic nerve head parameters, namely the depth and curvature of the lamina cribrosa (LC). ...
The results show that deep learning-based algorithms provide the highest accuracy, sensitivity and specificity for segmenting the different structures of the ONH including the LC. ...
Active contours In active contours methods, an object is segmented by an energy-minimizing contour guided by the surrounding pixels. ...

The lamina cribrosa (LC) is a tissue in the posterior eye with a complex trabecular microstructure. ...
We then apply a modified version of Frangi's vesselness filter to automatically segment the connective tissue beams of the LC and determine the orientation of each beam. ...
The authors gratefully acknowledge Jonathan Suever for helpful discussions on computational efficiency optimizations. Funding statement. ...
