When is pupil dilation typically performed?

Pupil dilation is typically performed during a comprehensive eye examination. This procedure involves the use of dilating drops to widen the pupils, allowing the eye care professional to get a better view of the internal structures of the eye, including the retina and optic nerve. By examining these areas while they are dilated, practitioners can identify potential issues such as retinal detachment, glaucoma, or diabetic retinopathy more effectively, which are crucial for diagnosing and planning treatments.

During routine check-ups, pupil dilation may not always be performed as the exam might focus more on visual acuity and eye health rather than an in-depth examination of the internal eye structures. Similarly, pupil dilation is not usually necessary when simply prescribing glasses, as the primary focus in that scenario is on refraction measurements rather than a thorough internal examination. Treating eye infections also typically does not require dilation, as the priority is to address the infection rather than to examine internal eye structures. Therefore, comprehensive eye examinations are the appropriate context for pupil dilation to occur.
