Task: Answer Verification
Input (English): Question: Do retinal vascular occlusions occur more frequently in the more affected eye in exfoliation syndrome?
Answer: Retinal vascular occlusion in patients with XFS occurs most often in the affected or more severely affected eye. As vascular occlusions happened in patients with and without glaucoma in similar proportions, the presence of XFS seems to play an important role in these findings.
Output (English): yes
