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.
