[Symmetrical carotid aneurysm on both sides (author's transl)]

The case of a 44-year-old female patient with angiographically established symmetrical aneurysm of the internal carotid artery on both sides near the origin of the arteria ophthalmica is reported. The right ophthalmic artery is not perceptible for a distance of 2 mm in its early upper portion. The left ophthalmic artery is well filled. The visual capacity of the right eye is reduced to 1/24, the left eye has one of 1.0. The lower half of the visual field including the fixation point fails. The left visual field is characterized by a pronounced irregular concentrical narrowing with preserved fixation point. The different filling of the ophthalmic arteries is responsible for the difference in the visual capacity and in the visual fields of both eyes. Because, neurosurgically, only a resection of both aneurysms comes into question, one desists from this proceeding because of the extraordinary high risk of such an operation.
