What is pingueculitis? |
|
|
Pingueculae appear as yellowish patches on the white of the eye (sclera), usually
forming on the side closest to the nose. These patches represent an alteration of
normal tissue that produces a deposit of protein and fat. Pingueculitis refers to
a condition in which the pingueculae become vascularized and inflamed and cause
redness and irritation. In severe cases of pingueculitis, very small ulcerations
may occur within the conjunctival epithelium. The eye responds to this ulceration
by attempting to cover the site of erosion, which leads to
pterygium formation.

Risk Factors |
|
|
Individuals at increased risk of developing pingueculitis include people
who spend large quantities of time outdoors (due to work or leisure) as well as
those who are in the "middle-age" category. Environmental irritants such as dust
or wind may also present a certain amount of increased risk.

Treatment |
|
|
An optometrist may prescribe lubricating eye drops or ointments in order
to reduce irritation. Topical steroids may be used in cases with significant inflammation.
In severe cases, surgery may be required.

Prevention |
|
|
Protective eyewear may be used to guard against environmental irritants.
Sunglasses with
100% UVA and UVB
protection are extremely beneficial to reducing risk of developing pingueculitis
as well as other ocular health issues.
This is a very common condition, and although noticeable, this is not
an infection, nor does it lead to vision loss. Many times, one may see yellow spots
on their eyes and seek eyecare at that time.
