What is normal fundus?
Normal Fundus. The disk has sharp margins and is normal in color, with a small central cup. Arterioles and venules have normal color, sheen, and course. Background is in normal color. The macula is enclosed by arching temporal vessels. The fovea is located by a central pit.
What is Tapetal fundus?
In the tapetal fundus, the choroid is modified to contain a highly-reflective anterior cellular layer, the tapetum. This layer is believed to act as a reflecting surface to enhance light stimulation of the retina.
What does a fundus photo show?
Fundus photographs are visual records which document the current ophthalmoscopic appearance of a patient’s retina. Fundus photography is also used to document the characteristics of diabetic retinopathy (damage to the retina from diabetes) such as macular edema and microaneurysms.
Where is the fundus of the eye?
Fundus is the bottom or base of anything. In medicine, it is a general term for the inner lining of a hollow organ. The ocular fundus is the inner lining of the eye made up of the Sensory Retina, the Retinal Pigment Epithelium, Bruch’s Membrane, and the Choroid.
What is the purpose of the fundus?
It provides a bird’s eye view of entire layers on the retina (the interior surface of the eye) and allows your doctor to provide the most accurate diagnosis.
What is the difference between retina and fundus?
In context|anatomy|lang=en terms the difference between retina and fundus. is that retina is (anatomy) the thin layer of cells at the back of the eyeball where light is converted into neural signals sent to the brain while fundus is (anatomy) the large, hollow part of an organ farthest from an opening; especially.
When using the ophthalmoscope it is best to?
Place your left hand on the patient’s head and place your thumb on their eyebrow. Hold the ophthalmoscope about 6 inches from the eye and 15 degrees to the right of the patient. Find the red reflex. Move in closer, staying nasally until you see the optic nerve.

Is fundus photography safe?
In countless retinal examinations and photographs performed over the past century, there are no reports of photic injuries from standard ophthalmoscopy, fundus photography or fluorescein angiography, despite the fact that injuries would be detected and documented in subsequent retinal examination and imaging.
What should a normal eye fundus look like?
The media are clear, providing a crisp view of the fundus. The optic disc appears pink with sharp margins and a cup-to-disc ratio of approximately 0.35. The vasculature is normal in course and caliber. The striated sheen radiating outward from the disc is evidence of a healthy retinal nerve fiber layer.
Why is fundus examination done?
This test is often included in a routine eye exam to screen for eye diseases. Your eye doctor may also order it if you have a condition that affects your blood vessels, such as high blood pressure or diabetes. Ophthalmoscopy may also be called funduscopy or retinal examination.
