ICD-10: H44.0

Purulent endophthalmitis, classified under ICD-10 code H44.0, is a serious ocular condition characterized by inflammation of the interior of the eye, typically due to infection. This condition can arise from various sources, including post-surgical complications, trauma, or hematogenous spread of infection. Understanding its clinical presentation, signs, symptoms, and patient characteristics is crucial for timely diagnosis and management.

Clinical Presentation

History and Onset

Patients with purulent endophthalmitis often present with a history of recent ocular surgery, such as cataract extraction, or trauma to the eye. The onset of symptoms can be rapid, occurring within days to weeks following the inciting event. In some cases, it may also develop after systemic infections or as a complication of other ocular diseases.

Symptoms

The symptoms of purulent endophthalmitis can vary in severity but typically include:

• Decreased Vision: Patients often report a sudden or progressive loss of vision, which is a hallmark symptom of this condition.
• Eye Pain: Severe ocular pain is common and may be accompanied by a sensation of pressure within the eye.
• Redness: Conjunctival injection (redness of the eye) is frequently observed, indicating inflammation.
• Photophobia: Increased sensitivity to light can occur, making it uncomfortable for patients to be in well-lit environments.
• Discharge: Purulent (pus-like) discharge may be present, particularly in cases where the infection is severe.

Signs

Upon examination, healthcare providers may observe several key signs indicative of purulent endophthalmitis:

• Corneal Edema: Swelling of the cornea can be noted, which may obscure the view of the fundus.
• Anterior Chamber Reaction: There may be a significant inflammatory response in the anterior chamber, including the presence of hypopyon (a layer of white blood cells in the anterior chamber).
• Retinal Changes: Fundoscopic examination may reveal retinal infiltrates, hemorrhages, or detachment, depending on the severity of the infection.
• Pupil Reaction: The pupil may be non-reactive or show a relative afferent pupillary defect, indicating potential damage to the optic nerve or severe retinal involvement.

Patient Characteristics

Demographics

Purulent endophthalmitis can affect individuals of all ages, but certain demographics may be more susceptible:

• Age: Older adults, particularly those undergoing cataract surgery, are at higher risk due to the prevalence of ocular surgeries in this population.
• Underlying Conditions: Patients with diabetes, immunocompromised states (such as those undergoing chemotherapy or with HIV), or those with a history of ocular disease are more likely to develop this condition.

Risk Factors

Several risk factors can predispose individuals to purulent endophthalmitis:

• Recent Ocular Surgery: Procedures like cataract surgery or intraocular injections significantly increase the risk.
• Trauma: Penetrating injuries to the eye can introduce pathogens directly into the intraocular space.
• Systemic Infections: Conditions that compromise the immune system or lead to bacteremia can also contribute to the development of endophthalmitis.

Conclusion

Purulent endophthalmitis is a critical ocular emergency that requires prompt recognition and treatment to prevent permanent vision loss. Understanding its clinical presentation, including the signs and symptoms, as well as the characteristics of affected patients, is essential for healthcare providers. Early intervention, often involving intravitreal antibiotics and possibly surgical intervention, is crucial for improving patient outcomes and preserving vision.

The cornerstone of treatment for purulent endophthalmitis is the administration of intravitreal antibiotics. Commonly used antibiotics include:
- Vancomycin: Effective against Gram-positive bacteria, particularly Staphylococcus species.
- Ceftazidime: Targets Gram-negative bacteria, including Pseudomonas aeruginosa.
- Amphotericin B: Considered if fungal infection is suspected.

The choice of antibiotics may be guided by culture results, but empirical therapy is often initiated immediately due to the urgency of the condition[1][2].

3. Surgical Intervention

In many cases, surgical intervention is necessary to manage purulent endophthalmitis effectively:
- Vitrectomy: This procedure involves the removal of the vitreous gel and any infected material from the eye. It is often performed in conjunction with intravitreal antibiotic injection.
- Anterior Chamber Paracentesis: This may be performed to relieve intraocular pressure and obtain samples for culture.

Surgical intervention is particularly indicated in cases where there is significant vitreous opacification or when the infection does not respond to medical therapy alone[3][4].

4. Systemic Antibiotics

In addition to intravitreal antibiotics, systemic antibiotics may be administered, especially if there is a risk of systemic infection or if the patient is immunocompromised. The choice of systemic antibiotics should be based on the culture and sensitivity results from intraocular samples[5].

5. Supportive Care

Supportive care is crucial in managing symptoms and preventing complications:
- Pain Management: Analgesics may be prescribed to manage discomfort.
- Monitoring: Regular follow-up appointments are necessary to monitor the response to treatment and adjust the management plan as needed.

6. Prognosis and Follow-Up

The prognosis for purulent endophthalmitis varies depending on the timing of treatment and the causative organism. Early intervention significantly improves outcomes, with some studies indicating that prompt vitrectomy and intravitreal antibiotics can preserve vision in a substantial number of cases[6]. Follow-up care is essential to assess visual recovery and detect any potential complications, such as retinal detachment or persistent infection.

Conclusion

The management of purulent endophthalmitis (ICD-10 code H44.0) requires a multifaceted approach that includes prompt diagnosis, intravitreal and systemic antibiotics, and often surgical intervention. Early recognition and treatment are critical to improving visual outcomes and preventing complications. Regular follow-up is essential to ensure the effectiveness of the treatment and to monitor for any adverse developments.
