Neovascular glaucoma is a dreadful pathology with a rapid spontaneous evolu
tion responsible for painful and blind eye. The main cause is an anterior n
eovascular proliferation following a broad retinal ischemia. Early diagnosi
s and treatment are required in order to maintain a good visual status and
a satisfactory IOP control with medical, surgical or cylodestructive proced
ures. In any case, the treatment of the retinal ischemia has to be performe
d. One must keep in mind that the most efficient way to avoid the incidence
of neovascular glaucoma is a strict control of clinical situations potenti
ally responsible for retinal ischemia, namely VRO in elderly patients and d
iabetic retinopathy in younger patients.
