Pinguecula

A pinguecula is a small yellowish bump that forms on the conjunctiva, the membrane that covers the white part of the eye, generally on the side closest to the nose. It is a benign and fairly common change on the ocular surface.

How it presents: it usually looks like a small yellowish bump; at times it causes a foreign-body sensation, dryness, or mild irritation, though often it produces no discomfort.

Contributing factors: prolonged exposure to sun, wind, dust, and dry environments.

When is it worth getting checked? If it grows, becomes red frequently, or causes persistent discomfort, it is worth an evaluation. The ophthalmologist confirms what it is and rules out other conditions, while the optometrist supports the care of visual health. With any change you notice on the surface of the eye, a professional consultation clears up questions.
