What does a pinguecula typically affect?

1. The back of the eye

2. The conjunctiva

3. The lens

4. The retina

The correct answer is: The conjunctiva

A pinguecula is a common, benign growth that typically forms on the conjunctiva, which is the clear membrane covering the white part of the eyeball and the inner surfaces of the eyelids. It appears as a yellowish, raised deposit and is often associated with exposure to UV light, dust, and wind. The growth is usually located on the side of the eye closest to the nose and can be a result of environmental factors or aging. The conjunctiva is directly impacted by a pinguecula due to this growth occurring on its surface. This condition does not involve deeper structures of the eye, such as the back of the eye, the lens, or the retina, which are not affected by this particular growth. The primary association of a pinguecula with the conjunctiva highlights its nature as a superficial ocular condition rather than one impacting other eye components.
