There are no major risks associated with funduscopy. The bright light used may cause minor discomfort for some patients. In addition, eye drops may cause a slight stinging sensation and a medicinal taste in the mouth as medication drains from the tear ducts into the throat.

In rare cases, the eye drops can cause more substantial reactions, such as:

• Nausea or vomiting
• Dizziness
• Dryness of the mouth
• Flushing
• Sudden increase in pressure inside the eye (acute angle-closure glaucoma)
