The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination). However, undilated examination is more convenient (albeit not as comprehensive), and is the most common type in primary care.
Examination findings may include microaneurysms, cotton wool spots, dot and blot hemorrhages, and neovascularization. [8] [10] Dilated fundus exam is the preferred method of diagnosis, as undilated exam may be too limited to visualize lesions or neovascularization that are more peripheral. [11]

An eye examination, commonly known as an eye test, [1] is a series of tests performed to assess vision and ability to focus on and discern objects. [2] It also includes other tests and examinations of the eyes. [2] Eye examinations are primarily performed by an optometrist, ophthalmologist, or an orthoptist.
Normal fundus photographs of the left eye (left image) and right eye (right image), seen from front so that left in each image is to the person's right.
