Pterygium: causes, symptoms, and treatment methods

Understanding pterygium: symptoms, causes, and prevention

Pterygium is a growth of connective tissue on the cornea of the eye, most often caused by excessive exposure to ultraviolet rays. The main symptoms of pterygium include the feeling of a foreign body in the eye, redness, and irritation of the conjunctiva.

Prevention of pterygium includes protecting the eyes from harmful UV rays with sunglasses and hats, as well as regularly using artificial tears to moisturize the eyes. In the case of pterygium, it is important to consult an ophthalmologist for evaluation and appropriate treatment.

Risk factors for pterygium

Pterygium is a pathological change in the cornea of the eye, characterized by the growth of conjunctival tissue onto the surface of the cornea. The main risk factors for the development of pterygium include prolonged exposure to ultraviolet rays, extreme climatic conditions such as wind and dust, as well as genetic predisposition. Studying these factors is important for the prevention and timely treatment of patients with pterygium.

  • Prolonged exposure to ultraviolet rays: Increased exposure to sunlight, especially without protective eyewear, can raise the risk of developing pterygium.
  • Extreme climatic conditions: Wind, dust, and other aggressive environmental factors may contribute to the development of pterygium.
  • Genetic predisposition: Heredity may play a role in the onset of pterygium, especially if family members have had cases of this condition.
  • Eye injuries: Damage to the cornea or conjunctiva caused by trauma or surgical intervention can increase the likelihood of developing pterygium.
  • Frequent use of contact lenses: Incorrect or prolonged wearing of contact lenses may contribute to the development of pterygium due to irritation of the eye tissues.

Pterygium manifests itself as a growth of tissue on the eye’s conjunctiva, which can extend onto the cornea.

Pterygium manifests as a protrusion of conjunctival tissue on the surface of the cornea of the eye. The main symptoms of pterygium include the appearance of red or pink patches on the sclera, a sensation of a foreign body in the eye, frequent dryness of the eyes, irritation, or itching. Some patients may also experience a feeling of sand in the eyes or discomfort when blinking. It is important to consult a specialist at the first signs of pterygium to start timely treatment and prevent possible complications.

  • Proliferation of conjunctival tissue: pterygium manifests as an increase in conjunctival tissue on the cornea of the eye.
  • Appearance of red or pink areas: red or pink spots appear on the sclera, indicating the presence of pterygium.
  • Feeling of a foreign body in the eye: patients may feel the presence of something foreign in the eye due to the presence of pterygium.
  • Frequent dryness of the eyes: dryness of the eyes is one of the common signs of pterygium, which can cause discomfort.
  • Eye irritation or itching: patients with pterygium may experience irritation or itching in the eye area.

Expert opinion on the treatment of pterygium

Experts in the field of ophthalmology recommend various methods for treating pterygium depending on the severity of the condition and the individual characteristics of the patient. One of the main methods is the surgical removal of pterygium, which may be recommended in the case of disease progression or the occurrence of noticeable cosmetic defects. After the surgery, specialists may also provide recommendations for preventing recurrence and restoring visual function.

Diagnosis of pterygium

The diagnosis of pterygium is based on a visual examination of the eye by an ophthalmologist. Pterygium can be recognized by the characteristic protrusion of conjunctival tissue on the cornea of the eye, usually with the presence of blood vessels. Additional diagnostic methods, such as the use of fluorescein dye and slit lamp, can assist the doctor in confirming the diagnosis of pterygium and assessing the degree of its development. It is important to consult a specialist at the first signs of pterygium for timely diagnosis and the necessary treatment.

  • Examination of the eye by an ophthalmologist to identify the characteristic protruding area of tissue on the cornea.
  • Application of fluorescein dye to assess the size and degree of development of pterygium.
  • Use of a slit lamp for detailed study of pathological changes in the eye area.
  • Sometimes additional examination is conducted using microscopy or other methods for more accurate diagnosis.
  • An important step is to consult a doctor at the first signs of pterygium for timely diagnosis and assessment of the eye’s condition.

Treatment of pterygium

Treatment of pterygium may include conservative methods such as the application of urea, steroid drops, or anti-inflammatory medications to reduce inflammation and tissue growth. In cases where pterygium causes significant discomfort or limits vision, surgical removal of the pterygium may be recommended. Surgical intervention, such as excision with tissue grafting or the use of autografts, may be performed to remove the protruding tissue and prevent recurrence of the pathology. Discussion of all possible treatment methods and the selection of the most appropriate approach should be conducted with an ophthalmologist based on the individual needs and characteristics of the patient.

  • Conservative treatment: Includes the use of urea, steroid drops, or anti-inflammatory medications to reduce inflammation and tissue growth.
  • Surgical intervention: In cases where the pterygium causes significant discomfort or limits vision, surgical removal of the pterygium may be recommended.
  • Excision with tissue grafting: One method of surgical treatment for pterygium is the removal of protruding tissue and replacement of the defect with tissue from another part of the body.
  • Use of autograft: This method involves using the patient’s own tissue, most often from the conjunctiva, to cover the exposed cornea after the pterygium has been removed.
  • Individual approach: It is important to discuss all possible treatment methods with an ophthalmologist and choose the optimal approach based on the specifics of each individual case.

Prevention of pterygium

Prevention of pterygium includes protecting the eyes from ultraviolet rays by using sunglasses and headwear on sunny days. It is important to avoid prolonged exposure to the sun, especially in conditions of increased ultraviolet intensity. Outdoor workers or those who frequently find themselves in extreme climate conditions should take precautions to protect their eyes from adverse environmental effects and reduce the risk of developing pterygium.

  • Using sunglasses: protecting eyes from ultraviolet rays can reduce the risk of developing pterygium.
  • Wearing headgear: wide-brimmed hats and caps help shield eyes from direct sunlight.
  • Avoiding prolonged sun exposure: reducing time outdoors during periods of high ultraviolet intensity can help prevent eye damage.
  • Maintaining eye moisture: using artificial tears or moisturizing drops can lower the risk of dry eyes and irritation of the conjunctiva.
  • Visiting an ophthalmologist: regular preventive check-ups can help identify early signs of pterygium and take measures to prevent its development.

Interesting facts about pterygium

Pterygium, although most commonly found on the cornea of the eye, can also occur in other locations, such as the nose or ear lobes. The reasons for the development of this pathological process are not fully understood; researchers suggest that ultraviolet radiation, the environment, and heredity may play a role in its formation. Interestingly, pterygium has a tendency for possible recurrence even after successful surgical removal, which underscores the importance of long-term monitoring and preventive measures for this condition.
