What is the purpose of a fundus examination?

The purpose of a fundus examination is to evaluate the health of the retina and optic nerve. This examination allows healthcare professionals to visualize the internal structures of the eye, particularly the retina, macula, and optic disc. During the examination, any signs of diseases such as diabetic retinopathy, glaucoma, or macular degeneration can be identified.

By assessing the appearance and condition of these structures, practitioners can gain insights into not only ocular health but also systemic conditions that may manifest as changes in the retina and optic nerve. This examination is crucial for diagnosing and monitoring various eye and health conditions, making it an essential component of comprehensive eye care.

Other choices are not related to the primary focus of a fundus examination. Measuring intraocular pressure is typically done through tonometry, assessing lens clarity is related to cataract evaluation, and checking for corneal abrasions involves external examination methods.
