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 Patients,

We will be reopening our office Monday, May 18, 2020, and would like to bring you up to date with the many very important physical and procedural changes we have made to our office to assure the highest level of health and safety for our patients and staff during these very challenging times.

We have consulted with our county, state and federal officials, as well as the CDC and other healthcare professionals, to incorporate the recommended and required safety measures throughout our office.

We sincerely apologize for any inconvenience we may have caused by rescheduling or postponing your earlier appointments.

To assure the health and safety of our staff and patients, as well as minimize any exposure, we have instituted the following changes. Please read through this entire document and print a copy so you are familiar with them.

1. Any and ALL appointments and visits will need to be scheduled. This includes the pickup of eyeglasses or trial contact lenses, frame selection, eyeglass repairs, and eyeglass adjustments.

2. Contact lenses will be shipped to all patients at no charge

3. To maintain social distancing and minimize any possible exposure, we have spread out our patient schedule.

4. 24-48 hours before your appointment, one of our staff will be calling to remind you of your appointment and discuss your ocular and medical history. In addition, they will ask you standard COVID19 screening questions and answer any questions regarding your upcoming exam. This will take 5 – 10 minutes but this initial call is important to allow you ample time in our office.

Please look for and answer this call.

5. In order to save time and keep everyone on schedule, any and all medications you are taking should be listed in as much detail as possible on a separate piece of paper, emailed to our secure site: DROXENBERG@COMCAST.NET, or entered on the patient registration form on our website: WWW.DROXENBERG.COM. This needs to be completed prior to your appointment and should include all systemic medications (diabetes, hypertension, etc.) and ocular medications (eye drops, glaucoma medicine, etc.).

6. On the day of your appointment please plan to arrive 15 minutes early and call us at (717) 394-3798 when you arrive. We will return your call when you will be allowed to enter. Entry will be through the front door only unless previously discussed with our staff. Only the person with the appointment will be allowed in the office with the exception of minor children who have the appointment. NOTE: Family members and/or friends will need to wait outside.

7. We will be taking your temperature in the vestibule and anyone with a temperature of 100 degrees or higher or who is sick will be rescheduled. If you feel ill, please reschedule your appointment.

8. All staff will have their temperatures checked 2 times daily for your safety.

9. All staff will wear a facemask while in the office. In addition, all patients must wear a facemask while in the office as mandated by Governor Wolf for all PA businesses. If you do not wear a facemask, one will be provided to you.

10. There are hand sanitizing stations strategically placed throughout the office. Please use them.

11. All frames will be disinfected before and after being handled by patients and staff. Frames will not be returned to the frame display until they are appropriately disinfected.

12. All exam room equipment will be cleaned and disinfected before and after each use according to the CDC guidelines.

13. Cleaning and disinfection of our office have always been a priority and this will continue in earnest.

14. Preferred payment is by credit card or checks at the time of services but cash will be accepted.

15. We have installed a plexiglass barrier on our front desk to comply with the CDC and state guidance.

16. Reception area chairs have been separated to maintain social distancing.

17. Patients who are physically disabled will be allowed entry through the rear door, with prior approval, following a temperature check and COVID19 screening. All other patients must enter through the front door and screening vestibule.

18. Above all else, your safety and health are our top priorities. We take this responsibility very seriously and have implemented these changes in procedures to achieve this.

Dr. Oxenberg has been providing eye care to you and your family since 1990 and expects to continue for many years to come.

If you have any questions and /or concerns, please feel free to email our office at droxenberg@comcast.net or call (717) 394-3798.

We look forward to seeing you all again!

Sincerely,

Dr. Larry Oxenberg
