Episcleritis is an inflammatory condition affecting the episclera, a thin layer of tissue located between the sclera and the conjunctiva of the eye. It appears as localized redness, swelling, and tenderness in the eye, and may be unilateral or bilateral. Episcleritis is often associated with systemic diseases such as inflammatory bowel disease, systemic lupus erythematosus, and gout, but is most often idiopathic. Visual acuity is usually not affected, but long-term inflammation can lead to complications if left untreated.
History of the disease and interesting historical facts
Episcleritis was first described in medical literature in the 19th century, but its true nature remained unclear until the early 20th century. Researchers such as the French ophthalmologist Charles Simon classified diseases of the sclera and episclera starting from clinical observations. Over the past centuries, our understanding of the etiology and pathogenesis of episcleritis has expanded significantly. Important advances in the understanding of the disease have impacted diagnosis and treatment, including the introduction of technologies such as ultrasound and biomicroscopy.
Epidemiology
According to recent studies, the prevalence of episcleritis ranges from 1 to 4 cases per 1000 people per year, indicating a moderate frequency of the disease in the population. It is important to note that episcleritis is more common among young and middle-aged people, especially in people aged 20 to 50 years. In addition, there is a slight preponderance among women, which may be due to hormonal changes and a predisposition to autoimmune processes.
Genetic predisposition to this disease
Although episcleritis is most often idiopathic, its association with certain genetic factors has been noted in several studies. Scientists have found that certain genes, such as the HLA system genes (especially HLA-B27), may be associated with an increased risk of developing the disease. People with these genetic markers may have an increased susceptibility to autoimmune and inflammatory diseases, which in turn may lead to the development of episcleritis.
Risk factors for the development of this disease
There are various risk factors that may contribute to the development of episcleritis, including:
- Autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis)
- Infectious diseases (herpes, chlamydia)
- Physical factors (eye injuries, exposure to ultraviolet radiation)
- Chemical factors (exposure to toxic substances such as solvents and dyes)
- Stress, both psycho-emotional and physical, can aggravate the condition
Diagnosis of this disease
Diagnosis of episcleritis includes several stages that help confirm the presence of the disease and exclude other causes of inflammation. The main symptoms of the disease include redness, swelling and pain in the episclera, which, as a rule, do not lead to deterioration of visual acuity. The examination methods used are as follows:
- Laboratory tests - tests for inflammation markers, the presence of infections and rheumatological diseases.
- Radiological examinations - not always applicable, but may include ultrasound of the eyeball.
- Other types of diagnostics include biomicroscopy using a slit lamp.
- Differential diagnosis is required to exclude other diseases such as scleritis, conjunctivitis and uveitis.
Treatment
Treatment of episcleritis is primarily aimed at relieving pain and inflammation. Common treatment approaches include:
- Pharmacological treatment includes nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and corticosteroids.
- Surgical treatment is usually not required, but in severe cases, intervention may be needed to restore stability to the eye.
- Other treatments include physical therapy and the use of artificial tears to improve the patient's quality of life.
List of medications used to treat this disease
The main drugs used for episcleritis include:
- Ibuprofen
- diclofenac
- Prednisolone
- Nise
- Artificial tears (eg Teva, Oftagel)
Disease monitoring
Monitoring of the patient's condition includes regular examinations by an ophthalmologist to assess the dynamics of the inflammatory process. The prognosis with timely intervention is usually favorable. Possible complications, such as the development of scleritis or deterioration of vision, require more careful monitoring and correction of treatment.
Age-related features of the disease
Episcleritis may manifest itself differently depending on the age group. Adult patients often report less pronounced symptoms, while in children and adolescents the disease may proceed more aggressively with pronounced clinical symptoms, which requires an individual approach to treatment.

Advice from Dr. Oleg Korzhikov
If symptoms such as redness and discomfort in the eye area occur, it is recommended to see a specialist immediately for diagnosis and treatment. It is important to avoid self-medication, as this may worsen the condition. It is also helpful to take precautions such as limiting eye exposure to ultraviolet radiation and managing stress to reduce the likelihood of flare-ups.
