What they are
A pinguecula is a raised, often yellowish area on the clear tissue covering the white of the eye. A pterygium is a fleshy growth that extends onto the cornea, the clear front window of the eye. Ultraviolet exposure is associated with both. They can look similar, but a pterygium can change the cornea’s shape or grow into the line of sight. 1 · 2
What you may notice first
Some cause no discomfort. Others produce visible redness, burning, a gritty feeling, or watering. A growing pterygium may blur vision by causing astigmatism or covering part of the cornea. 2
How they are diagnosed
An eye doctor examines the growth under magnification. Vision testing and measurements of the corneal shape may show whether it is affecting sight. A changing or unusual-looking growth should be examined rather than self-diagnosed. 2
Usual treatment options
UV-blocking sunglasses, a brimmed hat, and protection from dust and dryness can help reduce exposure. Lubricating drops may relieve irritation; prescribed anti-inflammatory drops are sometimes used for a limited period. Surgery may be considered for persistent symptoms, growth, visual effects, or selected appearance concerns. A tissue graft is often used with pterygium removal to reduce recurrence. Growth can still return, so follow-up matters. 1 · 3
Beatific Vision offers evaluation and, when appropriate, pterygium or pinguecula removal.
When to seek urgent care
Severe pain, pronounced light sensitivity, or a sudden vision change is not something to manage as a routine surface growth. Seek urgent eye assessment. 4 · 5
Questions to ask
- Is this growth affecting my cornea or vision?
- What would justify removal, and what is my risk of recurrence?
