The 1442 eyes studied (mean age: 52.48Â±11 years) included 816 eyes with a cataract and 626 eyes with a clear lens. Irrespective of age and AL, the distribution of mean lens thickness per clear lens and different cataract types is depicted in Table 1a.
While cerebral aneurysms are often symptomless, they can cause headaches on occasion. While not common, even an aneurysm that has not ruptured may cause headaches in some individuals. A person may notice an abrupt, severe headache, or a series of headaches different from their âusualâ ones.
Brain aneurysms are not tumors; they are areas in the brain arteries or veins that are abnormally weak and expand to form a ballooning or expansion of the vessel wall. They seldom produce any symptoms unless they begin to leak blood into the surrounding brain tissue or if they burst.
