Purpose:
|
: To report a patient with anterior communicating artery aneurysm simulating unilateral optic neuropathy.
|
|
Methods:
|
: A 52-year-old male patient with a history of mild hypertension was referred to Khatam-Al-Anbia Eye Hospital ,Mashhad, with subacute visual loss and vague painful movement of the right eye since one week before. Baseline ophthalmic examinations were normal exept for positive RAPD of the right eye. There was inferior altitudinal visual field defect in automated perimetry (30-2 SITA standard). Based on clinical features ,perimetric results, neurological consult and following brain angiographic imaging, he was diagnosed as a case of anterior communicating artery aneurysm. Abnormalities in visual evoked potential (VEP) showed decreasing amplitude of N75-P100wave one and two weeks after the initial exam
|
|
Results:
|
Anterior communicating artery aneurysm can cause visual loss and altitudinal visual field defect and may be masked by AION or optic neuritis symptoms and sign
|
|
Conclusion:
|
: In patients with unexplained visual acuity or visual field loss, compressive effect of arterial aneurysms on optic nerve should be remained in mind.
