Purpose: To explore the principals of relationship between ophthalmic changes and intracranial aneurysms by investigating ophthalmic symptoms result from intracranial aneurysms.

Methods: The relationship between different ophthalmic changes and different intracranial aneurysms, the effect of different operational interventions on the ophthalmic symptoms' improvement were analyzed

Results: Among 23 patients with ophthalmic changes,12 cases(52.17％)harbored posterior communicating aneurysms, petrosal segment internal carotid artery and paraclinoid internal carotid artery aneurysms were both 2 cases(8.70％),ophthalmic internal carotid artery, anterior cerebral artery, middle cerebral artery, posterior inferior cerebellar artery, intracavernous primary trigeminal artery, carotid bifurcation aneurysms were all 1 case(4.35％).The main ophthalmic symptoms of posterior communicating aneurysms were various degrees of oculomotor nerve palsy. Paraclinoid aneurysm accompanied by visual acuity decreasing, primary trigeminal artery aneurysm by abducens nerve palsy and petrosal segment internal carotid artery aneurysm by paroxysmal diplopia respectively. No improvement appeared in patients who underwent emboilization. All patients who underwent neck clipping had no or limited improvements.

Conclusions: There are some rules between ophthalmic changes and intracranial aneurysms with different locations and properties. With ophthalmic abnormal changes we can obtain earlier diagnosis of intracranial aneurysms, thus improve the prognosis of intracranial aneurysms remarkably.
