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 rarely causes any symptoms unless it bursts (ruptures). However, unruptured brain aneurysms occasionally cause symptoms if they are particularly large or press against tissues or nerves inside the brain. Symptoms of an unruptured brain aneurysm can include:ymptoms of a ruptured brain aneurysm usually begin with a sudden agonising headache. It's been likened to being hit on the head, resulting in a blinding pain unlike anything experienced before. Other symptoms include: 1  stiff neck. 2  feeling or being sick.
