Answers:
cataract is simply the opacity in the lens , some times accumulation of proteins or enlarment of the epithelial cells inside the lens !. the lens consists of central portioncalled lens capsule which grows with age in size , the nucleus is surrounded by the cortex and the cortex is surrounded by the capsule , anteriorly the caapsule is called aterior capsule and posteriorly towards the vitrous its called psoterior capsule ,
in posterior subcapsular cataract mostly occur with advancing age the nucleus increases in size and hence cause opacity in the lens , when the opacity is in the cortex near the posterior capsule this condidtion is called posterior subcapsular cataract !.!.
the ischemia simply means when you have low oxygen to any thing it is injured , ischemia of the optic nerve means the infarction of the part of optic nerve due to insufficient or blocked blood supply to it by the short posterior ciliary arteries !.!.
