Corneal opacity is a vision problem in which the cornea, the clear lens that covers the eye, does not let light pass completely through it as a result of disease or injury. When people experience this condition, their vision becomes obscured or clouded, and total vision loss can eventually be experienced.
Symptoms are linked to how big the aneurysm is, how fast it is growing and its location. Very small aneurysms which do not grow may go completely unnoticed. A large cerebral aneurysm (in the brain) may press on nerve tissue and trigger numbness in the face, or problems with the eyes.
Aneurysms. A brain aneurysm is a balloon or bulge in an artery where the artery wall has weakened. They're usually located on an artery at the base of the brain and typically develop where a major artery branches into smaller arteries.They can be life threatening if they burst, requiring emergency treatment. brain aneurysm is a balloon or bulge in an artery where the artery wall has weakened.
