Visual function restoring after trabeculectomy: between dream and reality

Glaucoma is characterized by the progressive degeneration of the optic nerve head (ONH) and retinal ganglion cells (RGCs). RGCs can be divided into basic regions, including the axon and synapse, the dendritic arbor, and the cell body (1). These compartments can independently be affected by degeneration processes and cause damage of the ONH (1,2).
