A member asked:
What is a posterior subcapsular cataract and ischemia of the optic nerve?
6 doctors weighed in across 3 answers
2 different things: There are many types of cataract. Posterior subcapsular cataract refers to cloudiness on the back part of the lens just under the capsule. This may be caused by injury, steroids, elevated blood sugar and aging. Ischemia of the optic nerve means that there is or was an episode of poor blood flow to the nerve which may result in vision loss.
