Neovascular glaucoma, as the primary complication of an ischemic central retinal vein occlusion, is commonly termed the "90-day glaucoma." Late onset neovascular glaucoma is not well documented in the literature, therefore this case is particularly unusual. The 76 year old black female presented to the clinic with a constantly painful, excessively red and tearing left eye FOURTEEN months after the initial onset of CRVO - nearly a year outside the traditionally recognized "danger" period. This presentation exemplifies that continual monitoring of the patient's ischemic retinal status with fundus exams and fluorescein angiograms well beyond the three to five month period may save a patient from the severely painful and visually threatening effects of NVG. The author will discuss the distinction of ischemic vs. non-ischemic CRVO as a critical factor in prognosis and management of neovascular complications. In addition, pathogenesis and various treatment options, medical and surgical, will be fully addressed.
