A pinguecula is a yellowish raised growth on the conjunctiva typically adjacent to the border where the colored part of the eye meets the white part of the eye. They usually appear on the side closer to the nose, are present in both eyes and are relatively permanent.
Although a pinguecula itself is usually harmless, it sometimes causes redness or irritation to the eye. Chronic exposure to sun and ultraviolet radiation is thought to be the most common reason for the development of pinguecula, and it typically takes months or years.
Causes & risk factors
Chronic exposure to sun and ultraviolet radiation is thought to be the most common reason for the development of pinguecula, and it typically takes months or years.
- Yellowish growth on the conjunctiva.
- May cause redness, irritation, and a change in the appearance of the eye.
- It can be in one or both eyes.
- More than one can be present in the same eye.
Your doctor of optometry can diagnose a pinguecula during a comprehensive eye examination where a microscope is used to evaluate the front structure of the eye.
For patients with eye discomfort associated with a pinguecula, your doctor may prescribe artificial tears, gels or ointments to provide more lubrication to the eye. This often helps to reduce the redness and irritation. In more severe cases, topical steroid drops may be used to control inflammation.
The best methods to prevent a pinguecula is protect the eye from ultraviolet radiation by wearing certified wrap-around sunglasses and brimmed hats while outdoors. Some prescription glasses also have lenses capable of protecting the eyes from ultraviolet rays.
Acanthamoeba is one of the most common organisms in the environment. Although it rarely causes infection, when it does occur, it can threaten your vision.
Accommodative dysfunction is an eye-focusing problem resulting in blurred vision—up close and/or far away— frequently found in children or adults who have extended near-work demand.
Amblyopia (lazy eye)
Amblyopia—also known as lazy eye—is the loss or lack of development of clear vision in one or both eyes.
