Intracranial aneurysms is a common disease of the nervous system. Most of them usually have no obvious clinical manifestations before rupturing. However, serious complications may happen, even to endanger the lives of patients after intracranial aneurysms rupture. A part of intracranial aneurysms can cause ocular manifestations, such as papilledema, retinal hemorrhage, vitreous hemorrhage, decreased visual acuity, visual field defect, oculomotor nerve palsy, abducens nerve palsy and trigeminal neuropathy, etc. The imaging diagnostic methods of intracranial aneurysms include computed tomography(CT), magnetic resonance angiography(MRA), digital subtraction angiography(DSA). The DSA is the most accurate method for the diagnosis of intracranial aneurysms. Morever, the treatment of intracranial aneurysms mainly rely on surgery, including microsurgical clipping and endovascular interventional therapy. The choice of surgery should be based on disease and medical conditions. (Int Rev Ophthalmol, 2017, 41: 18-22)
