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.
Unruptured brain aneurysm. Overview. An aneurysm is a balloon-like bulge of an artery wall. As an aneurysm grows it puts pressure on nearby structures and may eventually rupture. Most people find out they have an unruptured aneurysm by chance during a scan for some other problem. The risk of rupture varies depending on the aneurysm location and size.
