Tropicamide

Tropicamide is a fast-acting eye drop used to dilate the pupils before eye examinations or surgeries. It belongs to a class of medicines called anticholinergics, which temporarily relax the muscles in the eye, making it easier for doctors to examine the retina and other internal structures. It is commonly used in ophthalmology to perform detailed eye check-ups. The effects of Tropicamide are temporary, and vision returns to normal after a few hours. It should only be used under medical supervision to avoid potential side effects.

Uses of Tropicamide

• Used to dilate pupils for eye examinations
• Helps in diagnosing retinal and optic nerve conditions

• Reduces pain in eye inflammation

How Tropicamide Works

Tropicamide blocks the action of acetylcholine, a chemical responsible for controlling eye muscles. This leads to temporary pupil dilation (mydriasis) and relaxation of the focusing muscles, allowing doctors to examine the inner parts of the eye more clearly.
