A computer program for localizing visual field defects is presented. It is based on a decision tree which has been converted into a program written in Turbo-Pascal and can be run on any IBM-compatible computer. A question-and-answer routine guides the examiner to the localization of the defect.
The authors present three cases of AION with suspected temporal arteritis to show why a Doppler sonographic examination should be performed prior to a biopsy of the temporal artery. In Case 1, with stenosis of the internal carotid artery, the cerebral perfusion depended, entirely on collateral circulation, the nutritive vessel of which was the temporal artery. Cases 2 and 3 illustrate a proximal stenosis of the ophthalmic artery. In these two cases the temporal artery maintained the blood supply to the eye. All these findings were obtained by Doppler sonographic examinations. Biopsy of the temporal artery, which could otherwise have caused sudden death in Case 1, or blindness in Cases 2 or 3, was therefore dispensed with.
A total of ten transient oculomotor palsies of varying severity were observed in a 12-year-old boy from the age of ten months onward, accompanied by migraine-like headaches and vomiting. Damage to the oculomotor nerve due to swelling of the internal carotid artery (or an abnormal vessel) in the cavernous sinus was suspected as the cause.
