The fundus of the eye is the interior surface of the eye, opposite the lens, and includes the retina, optic disc, macula, and posterior pole.[1] The fundus can be viewed with an ophthalmoscope.[1] The term may also be inclusive of Bruch's membrane and the choroid.

The eye's fundus is the only part of the human body where the microcirculation can be observed directly.[2] The diameter of the blood vessels around the optic disc is about 150 μm, and an ophthalmoscope allows observation of blood vessels with diameters as small as 10 μm.[2]

Diagnosis

Medical signs that can be detected from observation of eye fundus include haemorrhages, exudates, cotton wool spots, blood vessel abnormalities (tortuosity, pulsation and new vessels) and pigmentation.[3]
