Purpose:
To present a case of 59-year-old woman with the symptoms of redness, proptosis of her left eye and temporary bruit in her head.
Methods:
Basic ophthalmological examination, measurement of proptosis, tonometry, visual field examination (Humphrey 30-2 threshold) CT, MRI and carotid angiography were performed.
Clinical Signs:
Proptosis of the left eye, dilatation of the episcleral vessels, fundus examination--optic disc normal, enlarged and engorged venous vessels, intraretinal haemorrhages in posterior pole. Tonometry--13 mm Hg--right eye, 24 mm Hg--left eye. Perimetry--general reduction of sensitivity. CT scan--abnormal structure (0.9 x 0.4 cm) in the medial part of the left orbit, without enhancement after applying contrast. MRI examination--enlargement of extraocular muscles of the left eye. Carotid artery angiography revealed indirect carotid--cavernous fistula.
Conclusion:
Special investigations like CT and MRI showed different picture, final diagnosis could be based upon the clinical picture and confirmed by angiography.
