What should be done if a patient reports sudden vision loss?

When a patient reports sudden vision loss, it is essential to recognize the urgency of the situation, as this can be indicative of serious underlying conditions that require prompt action. Immediate referral for further evaluation is critical because sudden vision loss could be a sign of conditions such as retinal detachment, stroke, or other ocular emergencies that may lead to permanent vision loss if not treated quickly.

In contrast, choices that suggest scheduling a routine eye exam, recommending over-the-counter eye drops, or waiting for symptoms to improve are not appropriate responses in this situation. A routine exam is typically intended for ongoing care and does not prioritize the immediate attention necessary for sudden changes in vision. Similarly, over-the-counter eye drops are unlikely to address the underlying cause of sudden vision loss and could delay necessary treatment. Waiting for a week risks the potential for irreversible damage to the patient's vision, as immediate intervention may be required depending on the cause of the vision loss.

The priority in cases of sudden vision changes is to ensure that the patient receives prompt and effective care, hence the correct course of action is to make an immediate referral for further evaluation.
