Endophthalmitis

Endophthalmitis is a severe inflammatory condition affecting the internal structures of the eye, including the vitreous and retina. It can be caused by infections, usually bacterial or fungal, and often occurs after eye surgery, trauma, or as a complication of other eye diseases. Endophthalmitis can lead to vision loss and requires immediate medical attention. The acute form of the disease can develop rapidly, while chronic cases are characterized by less severe symptoms. Clinical signs may include redness, swelling of the eyelid, pain, photophobia, and decreased visual acuity.

History of the disease and interesting historical facts

Endophthalmitis was first described in medical literature in the 19th century. One of the first significant cases was the description of inflammation that occurred after cataract surgery. Since then, the history of endophthalmitis has been filled with many significant discoveries and studies. In the early 20th century, the development of antiseptics and surgical techniques significantly changed the prognosis of this disease. Interesting fact: in the 1960s, after the introduction of intraocular lenses, cases of endophthalmitis increased significantly due to the increased trauma of operations. Endophthalmitis has become the subject of many studies aimed at quantitative assessment and prediction of treatment results.

Epidemiology

Endophthalmitis occurs with a frequency of 0.02% to 0.3% after eye surgery, making it a rare but serious complication. There are differences in the incidence depending on the type of surgery. For example, after cataract surgery, the risk of endophthalmitis is approximately 0.1%. In cases of penetrating eye trauma, such as wounds, this figure can increase to 7%. Endophthalmitis can also occur in patients with systemic infections or in people suffering from immunodeficiency. A significant proportion of cases are caused by gram-negative microflora, including pathogens such as Escherichia coli and Pseudomonas aeruginosa.

Genetic predisposition to this disease

Currently, research into the genetic predisposition to endophthalmitis is incomplete. There is evidence that variations in genes involved in the immune response may increase the risk of developing the disease. The main genes involved, such as IL-10 and TNF-α, may influence inflammatory responses to infections. Mutations in genes associated with the complement system may also contribute to increased susceptibility to infectious diseases such as endophthalmitis. However, more research is needed to better understand these mechanisms and develop genetic tests to predict the risk of developing the disease.

Risk factors for the development of this disease

Risk factors for endophthalmitis are varied and can be divided into several categories:

• Physical factors:
  • Penetrating eye injuries;
  • Recent eye surgery, especially cataract surgery;
  • Use of intraocular lenses.
• Chemical factors:
  • Contact with aggressive chemicals such as solvents or acids;
  • Exposure to chemicals during industrial activities.
• Other factors:
  • Systemic diseases such as diabetes;
  • Immune disorders, including HIV infection and other immunodeficiency states;
  • Long-term threat of infections in patients with chronic diseases.

Diagnosis of this disease

Diagnosis of endophthalmitis includes several key aspects:

• The main symptoms of the disease:
  • Eye pain;
  • Redness and swelling of the eyelid;
  • Decreased visual acuity;
  • Photophobia.
• Laboratory tests:
  • Primary analysis of tear fluid for the presence of pathogens;
  • Vitreous body cultures.
• Radiological examinations:
  • Ultrasound examination of the eye to assess the condition of the internal structure;
  • CT or MRI to exclude other pathologies.
• Other types of diagnostics:
  • Examination using biomicroscopy;
  • Evaluation of corneal permeability.
• Differential diagnosis:
  • Exclusion of other infectious inflammatory diseases of the eye, such as uveitis;
  • Diagnosis of the characteristics of inflammatory processes affecting the vascular membrane of the eye.

Treatment

Treatment of endophthalmitis depends on the etiology of the disease and includes both conservative and surgical methods:

• General treatment:
  • Antibiotic therapy depending on the identified pathogen:
  • Immunostimulating drugs.
• Pharmacological treatment:
  • Introduction of antibiotics directly into the vitreous body;
  • Corticosteroids to reduce inflammatory reactions.
• Surgical treatment:
  • Vitrectomy to remove inflammatory exudate;
  • Washing the eyeball using antiseptic solutions.
• Other types of treatment:
  • Physiotherapeutic methods to improve eye circulation;
  • General supportive therapy to strengthen the immune system.

List of medications used to treat this disease

The main medications used to treat endophthalmitis include:

• Antibiotics: vancomycin, gentamicin;
• Corticosteroids: prednisolone, methylprednisolone;
• Drugs for intravenous administration: ceftazidime;
• Progressive immunostimulants.

Disease monitoring

Monitoring of patients with endophthalmitis includes monitoring of visual functions with regular examinations:

• Control stages:
  • Regular check-ups after injury or surgery;
  • Systematic monitoring of the eye condition after the start of treatment.
• Forecast:
  • The prognosis depends on the time of initiation of treatment and the pathogen;
  • Timely intervention improves the outcome.
• Donkey complications:
  • Loss of vision;
  • Niodramatitis syndrome;
  • Recurrence of infections.

Age-related features of the disease

Endophthalmitis can manifest itself differently depending on the age group. In children and elderly patients, the disease often has a more aggressive course:

• In newborns, endophthalmitis most often develops as a result of congenital anomalies or birth injuries;
• Among older people, there is a high risk of postoperative infections due to a weakened immune system;
• Middle age is generally characterized by less pronounced symptoms, but requires careful monitoring of the latest trends in infectious pathology.

Questions and Answers

• What is endophthalmitis?
  Endophthalmitis is an inflammation of the internal structure of the eye, which can be classified as bacterial or fungal, and requires immediate medical attention.
• What are the main symptoms of endophthalmitis?
  The main symptoms include pain, redness of the eye, decreased visual acuity and photophobia.
• How to treat endophthalmitis?
  Treatment may include antibiotics, corticosteroids, and, in some cases, surgery such as vitrectomy.
• What is the prognosis for patients with endophthalmitis?
  The prognosis depends on the timeliness of treatment; if treatment is started on time, in most cases vision can be restored.

Advice from Dr. Oleg Korzhikov

If you suspect endophthalmitis, it is important not to delay a visit to the doctor, as the disease can progress quickly. Do not self-medicate or ignore mild symptoms such as redness or irritation. For prevention, pay attention to eye hygiene, especially after surgery, and follow your doctor's recommendations. Regular examinations by an ophthalmologist will help identify the early stages of the disease and prevent complications.
