Why is atropine used in eye examinations?

Atropine is used in eye examinations to dilate the pupils, a process known as mydriasis. This allows eye care professionals to get a better view of the interior structures of the eye, such as the retina and optic nerve, facilitating the diagnosis of various ocular conditions. Additionally, the dilation helps in assessing refractive errors and the overall health of the eye. The effects of atropine can last several hours, providing ample time for examination.
