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.
Most aneurysms remain small and are never diagnosed. Some, however, may gradually become larger and exert pressure on surrounding brain tissue and nerves and may be diagnosed because of stroke-like symptoms including: 1  headache, 2  numbness, or weakness of one side of the face, 3  a dilated pupil, or. 4  change in vision.
