What are Drusen? Some drusen can become larger, softer and closer together. Their edges are less distinct. When they get to that stage, there is a greater risk for developing wet macular degeneration and more severe vision loss. They can also disrupt the layers of the retina and may lead to retinal pigment epithelium detachment (PED).

Optic Disc Drusen Disc drusen are composed of small proteinaceous material that become calcified with advancing age. These deposits can be considered small tumors that develop within the optic nerve head, and may lead to an elevated disc (and therefore pseudopapilledema). They are bilateral in approximately 70% of cases.

What are Drusen? Drusen are tiny yellow or white deposits in a layer of the retina called Bruchs membrane. They are the most common early sign of dry age-related macular degeneration. Drusen are made up of lipids, a type of fatty protein. They may be the result of a failure of the eye to dispose of waste products that are produced when the photoreceptors of the eye drop off older parts of the cell. There are several types of drusen with different levels of risk.

Rheum dries and gathers as a crust in the corners of the eyes or the mouth, on the eyelids, or under the nose. It is formed by a combination of mucus (in the case of the eyes, consisting of mucin discharged from the cornea or the conjunctiva), nasal mucus, blood cells, skin cells, or dust.

- The cornea is a clear membrane made of collagen that covers the front of your eye. It protects the inside of the eye and focuses light that passed through it into the eye. If the cornea gets scratched, it can cause a corneal abrasion, and if it gets infected by a virus or bacteria, it can cause keratitis.

- The cornea is the clear tissue at the front and center of the eye. Its transparency permits light to pass into the eye, through the pupil, lens, and onto the retina at the back of the eye. The three major layers that compose the cornea are the outer layer or epithelial layer, the middle layer termed the stroma, and finally a single layer of cells called the endothelium. The curvature of the cornea plays an important role in focusing (refracting or bending) light. The normal cornea is smooth, clear, and tough. It helps protect the eye from infection, dust, and other foreign material.

Entropion Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes continuously rub against the cornea causing irritation. Entropion is usually caused by genetic factors. This is different from when an extra fold of skin on the lower eyelid causes lashes to turn in towards the eye (epiblepharon)[citation needed].

What Treatments Are Available for Dry Macular Degeneration? In dry age-related macular degeneration, small white or yellowish deposits, called drusen, form on the retina, beneath the macula, causing it to deteriorate or degenerate over time. Drusen are the hallmark of dry AMD. These small yellow deposits beneath the retina are a buildup of waste materials. They are made up of cholesterol, protein and fats.
