Question: What is end-stage glaucoma, and how serious is it? (Will blindness occur?)
Answer: End-stage glaucoma is generally the term we apply when there is very advanced disease. It is a very serious situation because that means there's not very much healthy tissue left. In other words, there has been a lot of visual damage. Blindness doesn't always occur once you've reached the advanced stage; however, the risk of blindness becomes much higher.
