Where are pinguecula typically found relative to the iris?

Pinguecula are typically found on the side of the eye closest to the nose, known as the nasal side. This condition refers to a benign growth or thickening of the conjunctiva, which often appears as a yellowish bump on the white part of the eye.

The occurrence of pinguecula is primarily related to environmental factors, such as sun exposure or irritation from wind and dust, which tend to affect the nasal conjunctiva more than the temporal side. Thus, the nasal positioning of these growths can be linked to the way they develop in response to these environmental irritants.

Pinguecula are not typically found directly over the pupil or centered on the iris. They may also appear on the outer side of the eye, but they are primarily associated with the area closest to the nose, which distinguishes their location significance.
