Background
To report a case of a cerebral Arteriovenous Malformation(AVM) with eye symptoms firstly and review the characteristic of this case and the main confusing point for diagnosis of such case.
Case presentation
A 58-year-old women presented to the ophthalmology clinic with 1 and an half year of right eye redness, Ocular hypertension and recurrent headache. One and a half year ago she was diagnosed as right eye dry eye and glaucoma and had received treatment according to diagnosis, however all the treatment did not lead to any improvement of redness and headache. On physical examination, it revealed dry eye and severe corkscrew hyperemia with dilated vessels in the right eye. After we consider that the symptom may be related to intracranial abnormal vessels, Computed tomography angiography and venography (CTA+CTV) were performed and the results showed an arteriovenous malformation (AVM) of right parietal-occipital area in the brain. The AVM was definitely located by the further examination of Digital subtraction angiography (DSA). After the AVM endovascular embolism treatment, the conjunctival congestion of the right eye was significantly relieved and the intraocular pressure was decreased to normal.
Conclusion
In clinical practice, when found corkscrew hyperemia accompanied by neurological symptoms, it might be considered as a result from cerebral vessels diseases, so in this case ophthalmologists diagnosis should combine disease history and imaging examination.
