The idea that fundus can and should correspond to a combining form fundo-drives the formation of an alternate form, fundoscopy (fundo-+ -scopy), which is the subject of a descriptive-versus-prescriptive difference in acceptance.
Medical signs that can be detected from observation of eye fundus (generally by funduscopy) include hemorrhages, exudates, cotton wool spots, blood vessel abnormalities (tortuosity, pulsation and new vessels) and pigmentation. [3] Arteriolar constriction, seen as "silver wiring", and vascular tortuosities are seen in hypertensive retinopathy.
Fundus photographs without an interpretation are seen as obsolete. The records should be legible, and contain suitable patient information and clinician details. The interpretation of fundus photographs that are glaucomatous must contain a description of the vertical and horizontal cup to disc ratio, vessel pattern, diffuse or focal pallor ...
The American Academy of Ophthalmology recommends comprehensive eye examinations, including dilated fundus examination, for asymptomatic patients without risk factors for eye disease at varying frequencies based on age: every 5–10 years in adults under 40 years, every 2–4 years in adults aged 40 to 54 years, every 1–3 years in adults aged ...
For example, retinoblastoma, a neuroblastic tumor that can cause a dampened or even white reflex, occurs in 1 in every 20,000 children. [4] Regardless of the effectiveness, it is a fast, inexpensive , and noninvasive exam that could identify ocular pathology which with early identification can alter the course of the disease.
5 minutes – late staining Fluorescein enters the ocular circulation from the internal carotid artery via the ophthalmic artery . The ophthalmic artery supplies the choroid via the short posterior ciliary arteries and the retina via the central retinal artery , but the route to the choroid is typically less circuitous than the route to the retina.

Figure 1 - Humphrey field analyser. Humphrey field analyser (HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. [1] The results of the analyser identify the type of vision defect.
