1. A computer-implemented method for identifying a type of choroidal neovascularization in a human eye, the method comprising:
receiving, in a processor, optical coherence tomography data of the human eye;
generating, in the processor, three-dimensional volume segments of the human eye using the optical coherence tomography data and using a neural network, such that at least some tissue layers or fluid layers of a retinal area of the human eye are represented using the three-dimensional volume segments; and
identifying, in the processor, the type of choroidal neovascularization in the human eye using the three-dimensional volume segments, the type of choroidal neovascularization comprising one or more of the following: classic choroidal neovascularization and occult choroidal neovascularization.
