Introduction. Ophthalmic artery aneurysms are infrequent lesions and they have very specific particularities. Objective. to present the anatomoclinical and surgical characteristic of our patients with ophthalmic aneurysms and to analyze our surgical results. Patient and methods. 604 patients with intracranial aneurysms were operated on between January 1982 and December 2004. There were 50 patients with ophthalmic artery aneurysms. Average age was 52 years, 80% were women, 60% harbored multiple aneurysms and 20% were giant lesions. 12% had bilateral ophthalmic aneurysms. 20% of ophthalmic aneurysms were incidental. 50% had ophthalmological manifestations; howewer, this presentation occurred in 100% of the patients with large and giant aneurysms. Initially, 12% of ophthalmologic disorders were missed. We utilized unilateral or bilateral pterional approach associated to others in multiple aneurysms. We performed retrograde decompression-suction technique modified for large and giant aneurysms. Results. Thirty patients (60%) obtained a complete recovery, fourteen patients (28%) an incomplete recovery and two were seriously disabled. There were not patients in vegetative state. There were four deaths (8%). 50% of postoperatory deficits disappeared and 64% of ophthalmologic disorders improved three months later. Conclusion. Microsurgical method allowed to treat unique, multiple, bilateral, large and giant ophthalmic aneurysms with good recovery of neurological and visual deficits.
