Macroaneurysm on the Optic Disc in a Patient with Aortic Dissection

PURPOSE We report a case of macroaneurysm on the optic disc, a rare location, accompanied by vitreous hemorrhage in a patient with aortic dissection. METHODS A 60-year-old female with a history of aortic dissection at the age of 51 presented with visual disturbance owing to vitreous hemorrhage in her right eye. During vitrectomy, we found a large macroaneurysm on the optic disc that was beating and oozing blood. However, the macroaneurysm was not treated. RESULTS The macroaneurysm gradually shrunk, and the beating and oozing of blood disappeared accordingly. CONCLUSION Up to now, there have been no reports of macroaneurysm on the optic disc in aortic dissection patients. The association between macroaneurysm on the optic disc and aortic dissection is unclear; therefore, additional case reports may be necessary. To the best of our knowledge, our case is the first one reported in the literature.
