What is the primary use of topical mydriatic medications?

The primary use of topical mydriatic medications is to dilate the pupil. Mydriatics work by causing the muscles in the iris to relax, which leads to an increase in the size of the pupil, or mydriasis. This dilation is often necessary for various diagnostic procedures, such as a comprehensive eye examination, where a wider view of the retina and other ocular structures is required.

Topical mydriatics are commonly utilized in situations such as fundoscopic exams or to assess for potential ocular conditions, including retinal detachments or other posterior segment issues. They can also help in the treatment of certain eye conditions related to muscle spasm. Understanding the main function of mydriatics is essential for their effective application in clinical practice.
