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.

Symptoms depend on the size of the aneurysm, how fast it is growing and its location. 2  A large cerebral aneurysm can lead to numbness in the face or problems with the eyes. 3  Cerebral aneurysms most commonly form at the base of the brain. 4  Around 1 in 4 aortic aneurysms occur in the thoracic area of the aorta.
