To evaluate the clinical features of ocular ischemic syndrome in Koreans. Methods

The medical records of patients who were presumed to have ocular ischemic syndrome by ophthalmic examination, and confirmed by carotid artery imaging, were retrospectively reviewed from 2010 to 2017. Results

A total of 22 patients and 27 eyes were included in the study. Twenty patients were male. The average age was 64.2 years. Fifteen patients had hypertension and fifteen patients had diabetes mellitus. Twenty-one patients presented with acute visual impairment at the initial visit. The average best-corrected visual acuity (BCVA) was a LogMAR of 0.89 ± 0.65, with an average IOP of 16.1 ± 6.9 mmHg. Elevated IOP > 21 mmHg was noted in five eyes (18.5%). Iris neovascularization was the most common (13 eyes, 48.1%) feature in the anterior segment. Retinal hemorrhage was the most common feature in the fundus examination (23 eyes, 85.2%). The average central submacular thickness was 255.0 µm, and there was no macular edema except for one case with vitreomacular traction syndrome on optical coherent tomography. Conclusions

A total of 90.9% of patients with ocular ischemic syndrome were males > 50 years of age. Most patients presented with acute visual impairment. There was no macular edema on optical coherent tomography of all eyes.
