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.
An aneurysm is a weakening of a blood vessel wall which then forms an outpouching that fills with blood. Aneurysms can form anywhere along an artery's path. In the brain, the most common location for an aneurysm is along the vascular tree at the base of the brain, called the Circle of Willis.he most common types of aneurysms are found in the arteries that connect the two internal carotid arteries: 30% of aneurysms form in the anterior communicating artery (AComm) and 25% form in the posterior communicating artery (PComm).
