The eye has a tissue that covers the surface. This tissue, called the conjunctiva, is much like the skin all over your body, and growths may appear with a slight color or no color at all. In many cases, these nodules do not cause problems, but a white bump could appear for a number of reasons. Knowing about some of these bumps will help you discuss your concerns with your doctor.
Pterygium
A pterygium consists of white, raised tissue that grows on the conjunctiva. A pterygium may start as a small bump, but it may continue to grow. In such cases, the pterygium may expand to cover a portion of the cornea, the front, clear dome over the eye. If this occurs, the pterygium may affect your vision, and an eye surgeon may need to remove the growth. Once removed, most patients have full recovery of vision. Pterygium may also cause discomfort or irritation, particularly with blinking. Artificial tears may help relieve these symptoms.
Conjunctival Tumor
A small tumor on the conjunctiva may also appear as an elevated bump. Certain cancerous tumors can spread to other areas, and your doctor will evaluate the best way to treat the conjunctival tumor. Eye surgeons will often recommend removing small tumors, but after testing, she may determine that freezing the tumor will provide the best protection for your eye. For benign tumors, an eye surgeon may recommend photographing the bump and monitoring the tumor for changes, says the Bascom Palmer Eye Institute.
Eyelid
A small, white bump on your eyelid may indicate a stye. A stye results from a blocked oil gland in the eyelid, and the bump will often disappear when the blockage dissolves. If the bump swells or turns red, you may wish place a warm, damp washcloth over the affected eyelid. This may help loosen the blockage. If the bump does not improve, your eye care provider may recommend eye drops or a quick in-office procedure to drain the gland.
Prevention
To prevent a blocked oil gland you should gently wash your eyelids each day. Use a gentle soap and carefully scrub along the eyelashes. This will help remove any debris that may result in a blockage.
People who have frequent exposure to sunlight, wind and other environmental elements have a greater risk for having a pterygium, explains MedlinePlus. Wear sunglasses or protective eyewear when outdoors because this will help protect the surface of your eyes from ultraviolet damage. Lenses with ultraviolet protection may also help prevent cancerous lesions on the surface of your eye.
Considerations
A growth on your eye requires evaluation from an eye care professional. Once you notice the bump on your eye, contact your doctor for an appointment. Early evaluation may help prevent continued growth, which could lead to discomfort or vision changes.
