PTERYGIUM

Pterygium is a vascular lesion that occurs in the white part of the eye, and it extends into the cornea (the transparent layer of the eye).

Pterygiums can affect one or both eyes. Although it is not considered a serious condition, these can cause the person's eye to become inflamed, red, and have a gritty sensation. In severe cases, the pterygium can continue to grow, covering the iris and pupil thus causing vision loss.

CAUSES & RISK FACTORS

The cause of pterygium is unknown, but a higher incidence has been noted in people who:

Are exposed to ultraviolet (UV) radiation.

Live in sunny weather and close to the equator.

Are exposed to dry and dusty environments.

Are mostly outdoors.

SYMPTOMS

This is a wedge-shaped growth of the conjunctiva that extends onto the cornea — the outer layer of the eye.

01

EARLY SIGNS & SYMPTOMS

  • Dryness

  • Gritty sensation

  • Redness

  • Inflamation

02

LATE SIGNS & SYMPTOMS

  • Increase in the size and spread of the lesion.

  • An unpleasant appearance of your eye due to the size of the lesion.

  • Blurred or double vision if pterygium grows into the cornea.

DIAGNOSIS

The diagnosis is made on your ophthalmological examination. The lesion is closely observed using the slit lamp. At the time of the removal of the pterygium, the tissue is sent to pathology to confirm the diagnosis.

It is very important you have your pterygium evaluated. Doing so, it will help us determine the effect it has on your vision, and it will allow us to rule out malignancy. In addition, in Horta-Santini Eye Care team will take a measurement of how far the pterygium extends over the cornea will be obtained and over time we will continue to remeasure and assess if the lesion is approaching your visual axis.

TREATMENTS

Initially the treatment of pterygium is to observe. It is monitored to see if the lesion grows and spreads over the visual axis. The symptoms of irritation, gritty sensation and tearing can be relieved with eye drops or ointments.

HOW WE TREAT PTERYGIUM

POSSIBLE COMPLICATIONS

Surgical risks, including the potential for recurrence after removal of the lesion, must be considered at the time of surgery. Unfortunately, pterygium surgery is not as simple as cutting it off the conjunctiva lesion and removing it from the cornea. Doing just that, carries an 80% risk of recurrence. It is important to note that most recurrences occur during the first-year post-surgery
