Age Related Oracular Degeneration: Quiz Test

Both Lucentis and Avastin are anti VEGF agents used to treat neovascularization in wet AMD. Anti VEGF agents work by blocking the action of vascular endothelial growth factor (VEGF), which is responsible for the growth of abnormal blood vessels in the retina. By inhibiting VEGF, these medications help to reduce the growth and leakage of abnormal blood vessels, thereby slowing the progression of wet AMD and preserving vision. Triamcinolone, on the other hand, is a corticosteroid medication and does not have anti VEGF properties.

Prolonged steroid use is not a risk factor for the development of Dry ARMD. Dry ARMD, or age-related macular degeneration, is primarily associated with aging, smoking, and exposure to the sun. Steroid use is not typically considered a risk factor for this condition.

Drusen are small yellow deposits that accumulate between the retinal pigment epithelium (RPE) and Bruch's membrane. These deposits are commonly found in age-related macular degeneration (AMD), a progressive eye condition that affects central vision. The presence of drusen can lead to the dysfunction and death of the underlying RPE cells, compromising the health of the photoreceptor layer and resulting in vision loss. Therefore, the correct answer is "Between the Retinal Pigment Epithelium and Bruch's Membrane."

A red/green color defect is not typical of early AMD. Early AMD is characterized by the presence of drusen, yellow deposits under the retina, and changes in pigmentation. These changes can cause blurred vision, difficulty recognizing faces, and decreased contrast sensitivity. However, a red/green color defect is more commonly associated with other eye conditions such as color blindness or certain types of retinal diseases.

This answer is correct because it describes the signs of Moderate AMD, which include a single large druse, some medium-sized drusen, and atrophy of the RPE that does not include the macula. The presence of a single large druse and medium-sized drusen indicates the presence of drusen deposits, which are a hallmark sign of AMD. Atrophy of the RPE refers to the degeneration of the retinal pigment epithelium, which can lead to vision loss. However, since the atrophy does not include the macula, the central vision may still be preserved to some extent.
