Pingueculae & Pterygia

Pingueculae and Pterygia are both benign growths that develop on the surface of the eye. While often grouped together, there are some differences in expression, symptoms, causes and treatment so here is an explanation of each condition and the differences between them.

Pinguecula

Pingueculae (pinguecula in singular) are growths that occur on the conjunctiva or the thin clear layer that covers the white part of the eye known as the sclera. They can be diagnosed on patients of any age, but tend to be more common in middle age. Pingueculae are typically yellowish in color and appear as a small, raised, sometimes triangular protrusion close to the cornea.

Causes of Pinguecula

Pinguecula occur when bumps, typically containing fat and/or calcium, form on the tissue of the conjunctiva. The exact cause of pinguecula is not known but there is a correlation between unprotected exposure to sunlight, wind, excessive dryness and dust.

Symptoms of Pinguecula

Pingueculae may have no symptoms or they can cause feelings of dryness, irritation or feeling like there is a foreign body in your eye. In more severe cases they may become itchy, inflamed, red and sore.

Treatment of Pinguecula

Often, there is no treatment necessary other than to protect the eye from the sun and other elements. If however, the pinguecula is causing discomfort or other issues, there are treatments available depending on the symptoms. Dryness, irritation and itchiness can sometimes be treated with eye drops or ointment and in cases where there is swelling, steroid eye drops along with anti-inflammatory medication may be prescribed. In rare cases that the pinguecula is causing serious problems such as vision problems, untreatable discomfort or preventing blinking, or the patient is unhappy with the way it looks, it may have to be removed surgically.

Pytergia

Pytergia (pytergium in singular) are wedge-shaped growths on the surface of the cornea (the sclera), made of fibrous conjunctival tissue and containing blood vessels, which sometimes make it appear pink. Pytergia often grow out of pinguecula and tend to be more visible.

Causes of Pytergia

Like pinguecula, pytergia are believed to be caused by extended exposure to UV rays from the sun and are sometimes called “surfer’s eye”. They are more common in adults (ages 20 – 50) who live in dry, sunny climates and spend significant time outdoors. Risks increase in those who do not properly protect their eyes by using sunglasses and hats when they are outdoors.

Symptoms of Pytergia

Pytergia may occur in one or both eyes and usually grow in the corner of the eye closest to the nose in toward the cornea. Very often there are no symptoms however some people may experience dry eyes, redness, irritation, the feeling that something is in their eye and inflammation. Pytergia may also cause discomfort for contact lense wearers. If the pytergium is serious it could grow far enough into the cornea to obstruct vision or cause the cornea to change shape resulting in astigmatism.

Treatment for Pytergia

If necessary, treatment for symptoms of pytergia may be similar to those used for pytergia such as lubricating eye drops or steroidal drops or creams to reduce inflammation. Surgery is more common for pytergia because of the more obvious change in appearance and because of the potential for vision disturbances. Sometimes a conjunctival graft is performed to prevent recurrence which is when a small piece of tissue is grafted onto the area where the pytergia was removed.

Pytergia and pingueculae are often completely benign conditions but should be monitored by a doctor to ensure they do not get worse and pose a threat to vision. Nevertheless, these growths go to show how important it is to protect your eyes from the harmful UV rays of the sun.

Dear valued patient,

We take our commitment to keeping our patients and team safe and healthy inthe midst of this COVID-19 pandemic very seriously. We want to share our plan to comply with social distancing guidelines for your upcoming appointment. Please carefully read the steps below and follow our direction when you arrive. Our team will all be wearing masks and we ask that you bring one with you to wear during your visit (for everyone’s safety, we are requiring staff and patients to wear masks).

We ask patients to complete necessary paperwork online if possible. Click here to access the forms. You may also choose to text a photo of your insurance card and photo ID to the clinic at 763-537-3213.

When you arrive for your appointment, enter the main doors and wait in the front alcove until a staff member greets you. Our front desk team will ask you general health questions to rule out the presence of COVID-19 symptoms.

We are asking that only the patient enter the building for the exam. (Exceptions: Children under 18 may be accompanied by one guardian, and adults with special needs may be accompanied by one caretaker.)

When you enter the building:

Staff will ask you to use hand sanitizer and then you will complete any necessary paperwork that you were not able to complete online, and we will make copies of your insurance card and photo ID if you did not text a picture of them to us.

Prior to seeing your doctor, a technician will escort you to a pre-testing room where you will be asked to wash your hands. We ask that you follow the CDC’s recommendation of washing your hands thoroughly, for a full 20seconds, with soap and water.

Rest assured that every surface and every piece of equipment you come into contact with has been sanitized prior to the arrival of each and every patient entering our practice, and it will be cleaned again as you exit each area.

The team will be frequently washing their hands between interactions as per our usual protocol, and you’ll also see hand sanitizer throughout the practice for your use, as well.

Optical – Shopping for Glasses, Adjustments and Repairs, and Glasses Pick-up

We are scheduling appointments for all optical needs. Please call the clinic at 763-537-3213 to schedule your appointment.

When you are shopping for glasses, one of our ABO certified opticians will ask you to be seated at a station where you will discuss your needs, likes and dislikes. To ensure social distancing, the optician will bring frames to you so you can try them on at the station. The optician will continue to bring frames to you until you find the perfect pair!

We sterilize every frame a patient touches in a UV Cleaning Unit after a shopping appointment so you can be assured any frame you try on has been sanitized prior to your visit.

If you have any questions or concerns, please don’t hesitate to call us. We look forward to seeing you!

Thank you for your patience and cooperation,

Your Crystal Vision Clinic Eye Care Team
