In glaucoma, disease evolution may not be predicted only from intraocular pressure (IOP) in some patients, as successful IOP-lowering treatment does not always prevent progression. Some patients, such as those with normal-pressure glaucoma, may have more susceptible optic nerves than others. There are several reasons to characterise glaucoma as a neuronal disease, and there is some evidence that IOP is only one of a number of co-factors leading to glaucoma. This paper provides an overview of some of the mechanisms that may be operating at the level of the retinal ganglion cell.
