T49.5: Poisoning: Ophthalmological drugs and preparations

The relevant agent is usually applied topically. Topically applied agents are those that are not taken as tablets or received as injections, but instead usually applied directly to the place where they are intended to have effect. These include ointments and drops, for example.

An agent can cause poisoning if too much of it is taken. The agent may also be administered or taken by mistake. The symptoms can vary depending on which agent has caused the poisoning.
