Answer

Patients with CRAO may develop a cerebrovascular accident due to secondary emboli. Park et al found that patients with CRAO had a significantly increased risk for stroke and acute myocardial infarction, particularly during the first week following CRAO. [19] Further emboli could travel to the same or contralateral eye, resulting in further visual loss. Ocular neovascularization, including neovascular glaucoma, occurs in approximately 15% of patients with CRAO, especially in those with diabetes mellitus, type 2. [20]
