Tropicamide
Tropicamide
Tropicamide (pronounced troh-pi-ka-mide) is a medication used in eye examinations to dilate the pupils and relax the muscles in the eye. It is classified as an anticholinergic drug.
Etymology
The term "Tropicamide" is derived from the Greek word "tropos", meaning "turn", and "amide", a common suffix in organic chemistry referring to a compound containing the functional group -CONH2.
Usage
Tropicamide is primarily used by ophthalmologists during eye examinations. It works by blocking the responses of certain nerves in the eye, causing the pupil to dilate and the muscles controlling the lens to relax. This allows the ophthalmologist to examine the back of the eye, including the retina and optic nerve, more easily.
Side Effects
Possible side effects of tropicamide include blurred vision, sensitivity to light, and stinging or redness in the eye. In rare cases, it can cause an allergic reaction.
