    摘要： An agent for the prophylaxis and treatment of disturbance of visual function, which comprises a compound of the formula �I! ##STR1## wherein A ring is optionally substituted;R.sub.1 is a hydrogen or an optionally protected amino; andR.sub.2 is a group capable of releasing a proton,or a salt thereof. The agent for the prophylaxis and treatment of disturbance of visual function of the present invention has superior preventive and therapeutic effect on asthenopia, and shows suppression of axial elongation, suppression of degradation of retinal functions and retinal function-recovery action. Hence, the agent can be advantageously used as a clinically applicable agent for the prophylaxis and treatment of disturbance of visual function.
