Case: A 53 years old female patient is suffering from chronic-recurrent
events of a amaurosis fugax in the oculus ultimus with up to 100 events
per day. The number of the events is increasing from the beginning in
the age of 10. Furthermore she has sometimes episodes of headaches. A
neurological examination did not detect any reason. A Horton´s disease
was excluded. The other eye was blinded by a chronic iritis, and a funduscopy
is impossible. The examination of the stricken eye shows no suspect findings
except some dilated veins. During a 10 second attack the venous vessels
show a huge dilatation and winding and the optic disc margins is blurred
(Video). The blood flow in the A. centralis retinae is moderate decreased
in case of amaurosis fugax. Other intraorbital vascular abnormities were
not found. Both CT and MRI angiography in highest resolution has shown
any intracranial or intraorbital pathology.
Conclusions: A reason of chronic-recurrent attacks of temporary
blindness has not yet been found. Possible explanations could be an unknown
vessel anomaly or an atavistic muscle. An accordingly diagnostic detection
failed in doing.
