What is the examination of the back of the eye known as?

The examination of the back of the eye is known as a fundus examination. This procedure allows healthcare professionals, particularly ophthalmologists or optometrists, to inspect the retina, optic disc, macula, and blood vessels of the eye. By using instruments such as an ophthalmoscope, a detailed view of these internal structures can be obtained, which is essential for diagnosing various eye conditions like diabetic retinopathy, glaucoma, and macular degeneration.

In contrast, lensometry refers specifically to measuring the prescription of lenses, visual acuity tests are designed to assess the sharpness of vision, and a retinal assessment generally focuses on the evaluation of the retina but does not encompass the broader view that the fundus examination provides. Therefore, the fundus examination is the correct term for this comprehensive evaluation of the back of the eye.
