Which physical examination finding is indicative of wet macular degeneration?

The presence of grayish-green discoloration near the macula is indicative of wet macular degeneration, which is characterized by the development of neovascularization (the growth of new blood vessels) beneath the retina. This abnormal growth can lead to fluid leakage and subsequent damage to the retinal cells, resulting in the distinct grayish-green appearance that can be seen during an eye examination.

In contrast, the presence of drusen is more commonly associated with dry macular degeneration. Drusen are small yellowish deposits that form beneath the retina and are often found in individuals with early stages of dry macular degeneration, serving as a risk factor for progression but not specifically indicative of the wet form. Excessive tearing is not a hallmark of wet macular degeneration and pertains to different ocular conditions. Lastly, loss of peripheral vision is generally associated with other retinal disorders or conditions, such as glaucoma, rather than wet macular degeneration, which primarily affects central vision.

Overall, the distinctive grayish-green discoloration observed near the macula is a key finding that helps differentiate wet macular degeneration from other forms of ocular pathology.
