Provided are methods and compositions for maintaining the viability of retinal ganglion cells in a subject with an ocular disorder including, for example, glaucoma and optic nerve injury. The viability of the retinal ganglion cells can be preserved by administering a necrosis inhibitor either alone or in combination with an apoptosis inhibitor to a subject having an eye with the ocular condition. The compositions, when administered, maintain the viability of the cells and/or promote axon regeneration, thereby minimizing the loss of vision or visual function associated with the ocular disorder.
