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.
A brain aneurysm usually forms in an artery, which is the type of blood vessel that carries oxygen-rich blood to the brain. Over time, these weak areas in the walls of arteries balloon out, causing the blood vessel wall to become even weaker as the aneurysm grows. Occasionally aneurysms can leak or rupture and cause a hemorrhagic stroke, the type of stroke that is caused by bleeding inside the brain.
