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.
In other cases, an unruptured aneurysm will cause problems by pressing on areas in the brain. When this happens, the person may suffer from severe headaches, blurred vision, changes in speech, and neck pain, depending on what areas of the brain are affected and how bad the aneurysm is.
