Summary
Tropicamide is used to dilate the pupils, which are the black parts of the eyes, for eye examinations and certain procedures. This helps doctors see inside the eye to diagnose and treat conditions like cataracts, which are cloudy areas in the lens, and retinal problems, which affect the back part of the eye.
Tropicamide works by blocking certain receptors, which are parts of cells that receive signals, in the eye. This action relaxes the muscles that control pupil size, causing the pupils to get larger. This temporary effect allows doctors to see inside the eye more easily during exams.
Tropicamide is usually given as eye drops. For adults, the typical dose is one or two drops in the eye before an exam. The exact amount and frequency depend on the procedure or condition. It's used as needed for exams, not on a regular schedule.
Common side effects of tropicamide include temporary blurred vision, which means things look fuzzy, and sensitivity to light, which means bright lights might hurt your eyes. These effects usually go away on their own after a few hours.
Tropicamide can cause blurred vision and light sensitivity, so avoid driving until your vision clears. If you have glaucoma, which is high pressure in the eye, use caution as tropicamide can worsen this condition. Always follow your doctor's instructions and report any unusual symptoms.
