Fish eye disease (pterygium) is a progressive conjunctival disease characterized by the formation of fibrovascular tissue on the surface of the white of the eye. This condition can cause not only aesthetic discomfort, but also lead to visual impairment, especially in more advanced cases when pterygium begins to spread to the cornea. The main cause of its development is considered to be exposure to ultraviolet radiation, as well as other environmental factors such as Pfeffermühle and industrial accidents. It is important to note that the disease can be recurrent, which requires special attention to monitoring and treatment.
History of the disease and interesting historical facts
Pterygium has been known to medicine for many centuries. An interesting fact is that references to the disease can be found even in the writings of ancient Greek doctors, such as Hippocrates. In the Middle Ages, the study of pterygium continued, and this disease was part of various medical treatises that described its symptoms and treatment. At the end of the 19th century, with the development of anatomy and ophthalmology, the first successful surgical interventions for the removal of pterygium began. In modern times, diseases and their treatment methods have become the subject of numerous studies, which has significantly improved the quality of medical care.
Epidemiology
According to the World Health Organization, the incidence of pterygium varies depending on climate conditions and region of residence. The highest rates are observed in countries with tropical and subtropical climates, where the level of UV radiation is significantly higher. Statistics show that the risk of developing pterygium increases with age. About 10% of the population over 40 years of age have signs of this disease, and among people over 60 years of age, this figure can reach 30%. In addition, there is a noticeable predisposition among certain professional groups working outdoors.
Genetic predisposition to this disease
Studies conducted on twins and families indicate the presence of genetic aspects that contribute to the development of pterygium. In particular, several genes have been identified that may be involved in the pathogenesis process, including genes responsible for the regulation of inflammatory processes and the interaction between epithelial and mesenchymal cells. One of the key mutations associated with the development of the disease is the polymorphism of the IL-6 gene, which is involved in immune reactions and may increase the predisposition to inflammatory processes in the ocular surface.
Risk factors for the development of this disease
Risk factors that contribute to the development of pterygium can be divided into physical and chemical:
- Physical factors: Long-term exposure to ultraviolet rays, high temperatures and harsh weather conditions such as wind and sand.
- Chemical factors: Exposure to harmful chemicals such as smoke or dust, as well as some cosmetics, can cause chronic eye irritation.
Additionally, previous eye conditions such as allergic conjunctivitis or long-term contact lens use may increase the risk of developing pterygium.
Diagnosis of this disease
Pterygium is diagnosed by visual examination of the eyeball by an ophthalmologist, who evaluates the extent of fibrovascular tissue spread. The following methods can be used to confirm the diagnosis:
- Laboratory tests: tests for the presence of inflammatory markers.
- Radiological examinations: the use of biomicroscopy for a detailed study of the condition of the conjunctiva and cornea.
- Other diagnostic tests include optical coherence tomography (OCT) to assess the depth of corneal damage if the disease is vision-threatening.
Differential diagnosis should be made with similar diseases such as conjunctivitis, adenovirus infection or other forms of ocular umbilical cord.
Treatment
Treatment of pterygium includes both conservative and surgical approaches. In the early stages of the disease, agents are used to reduce inflammation:
- General treatment: use of anti-inflammatory and moisturizing drops.
- Pharmacological treatment: administration of corticosteroid drops to reduce inflammation.
- Surgical treatment: removal of pterygium in case of significant deterioration of vision or discomfort.
- Other treatments include the use of autochimeric gels or preserved donor membranes to reconstruct the ocular surface after pterygium removal.
List of medications used to treat this disease
The following medications are used to treat pterygium:
- Dexamethasone (drops)
- Normolux (hydroprotective drops)
- Cyclosporine A (drops to reduce inflammation)
- Tobramycin (antibiotic drops to prevent infection)
Disease monitoring
Control stages in monitoring patients with pterygium include regular eye examinations every 6-12 months. The prognosis of the disease is generally favorable with timely treatment. However, complications are possible, such as recurrence of pterygium or development of other eye pathologies, in particular, cataracts.
Age-related features of the disease
In children and adolescents, pterygium is rare and often responds to treatment. In older people, the disease can be more aggressive and be accompanied by significant visual impairment and the development of concomitant eye diseases. The older age group requires more careful monitoring of the eye condition.
Questions and Answers
- What is pterygium?
Pterygium is a condition that causes fibrovascular tissue to form on the conjunctiva, which can lead to visual impairment and aesthetic problems. - What are the main causes of pterygium?
The main causes include prolonged exposure to ultraviolet radiation, as well as atmospheric and chemical irritants. - How is pterygium diagnosed?
Diagnosis is made by visual examination and additional studies such as biomicroscopy and optical coherence tomography. - What treatment is indicated for pterygium?
Treatment can be conservative (anti-inflammatory drops) or surgical (pterygium removal) depending on the stage of the disease. - What is the prognosis for pterygium?
The prognosis is generally good with adequate treatment, but there is a risk of relapse.
Advice from Dr. Oleg Korzhikov
Fish eye disease requires a comprehensive approach to treatment and prevention. It is important to follow simple recommendations:
- Use sunglasses, especially when exposed to bright sunlight.
- Try to minimize contact with harmful chemicals or dust.
- Visit your eye doctor regularly to monitor your eyes and detect problems early.
- Maintain good health, wear contact lenses if necessary, and avoid prolonged exposure to ultraviolet rays.
By following these recommendations, you can significantly improve your quality of life and maintain the health of your eyes.
