2023年9月18日 · Drusen occur beneath the retina and are usually, but not always, a sign of age-related macular degeneration (breakdown of tissues in the back of the eye). Exudates typically are within, or immediately under, the retina and typically …

2021年11月30日 · Exudative macular degeneration is a progressive eye disease that affects the macula or central part of the retina. It causes the eye to develop leaky blood vessels behind the macula, the part...

2025年1月2日 · Exudates, or deposits of fluid and lipids, are a common feature of macular degeneration and can indicate disease progression. Different types of exudates, such as hard and soft exudates, have varying significance in the diagnosis …

Hard exudates are 500 µm or less (1/3 DD) from the center of the macula with thickening of adjacent retinal tissue. Regardless of the level of their diabetic retinopathy, these patients should be observed for a decrease in vision and monitored with macular OCT and fluorescein angiography, especially if they have CSME.

Increased vascular permeability allowing the leakage of fluid and lipoprotein into the retina resulting in thickening of the macula; Resorption of the edema commonly results in precipitation of lipid residues within the outer plexiform (Henle's) layer; Clinical Features. Symptoms: various degree of decreased vision if involving the macula; Signs:

In diabetic retinopathy, hard exudates with associated retinal thickening located within 500 microns of the center of the fovea is referred to as clinically significant macular edema (CSME). The ETDRS report 22 found an association of hard exudates with elevated serum lipid levels.

2015年3月15日 · In each of these conditions, the pattern of exudate—or lipid deposits resulting from leakage—may be different. For example, the two common conditions resulting in a so-called “macular star” exudate are hypertensive retinopathy and neuroretinitis.

2025年1月1日 · Exudative age-related macular degeneration (AMD) is a chronic eye disease that causes blurred or distorted vision due to abnormal blood vessel growth and leakage in the macula, the central part of the retina.

2025年1月4日 · Exudates in diabetic retinopathy are a buildup of fluid and lipids in the retina, often caused by damage to blood vessels due to diabetes. Causes and risk factors for exudates in diabetic retinopathy include uncontrolled blood sugar levels, high blood pressure, and long duration of diabetes.

2019年3月1日 · The image below shows extensive haemorrhages, cotton wool spots, optic disc swelling and a ring of exudates around the macula (macular star). See our guide to hypertension for more details.
