Introduction:

Endophthalmitis is a severe and potentially sight-threatening complication that can occur after cataract surgery. This comprehensive article aims to provide a detailed understanding of endophthalmitis following cataract surgery, including its etiology, risk factors, clinical features, diagnosis, and management.

Etiology and Risk Factors:

Endophthalmitis is commonly caused by bacterial contamination of the eye during or after cataract surgery. The main risk factors for developing endophthalmitis include:

• Poor preoperative ocular hygiene
• Inadequate intraoperative sterile technique
• Delayed or inappropriate postoperative management
• Immunocompromised status
• Presence of preexisting ocular surface diseases

Clinical Features:

Endophthalmitis typically presents within a few days to weeks after cataract surgery. The following are common clinical features:

• Pain and Redness: Patients may experience severe eye pain, redness, and conjunctival injection.
• Decreased Visual Acuity: Rapid deterioration of vision is a hallmark sign of endophthalmitis.
• Hypopyon: The accumulation of white blood cells in the anterior chamber of the eye may lead to the formation of a hypopyon, which appears as a white layer.
• Fibrin and Pus Formation: The anterior chamber may show signs of fibrin and pus formation, indicative of infection.

Diagnosis:

Prompt diagnosis is crucial to prevent further vision loss. The diagnosis of endophthalmitis is based on clinical examination and the patient's history. Ophthalmologists may perform the following tests:

• Slit-lamp Examination: A thorough examination of the anterior and posterior segments of the eye is performed using a slit lamp.
• Ultrasound B-scan: This imaging technique helps visualize the posterior segment of the eye, especially if the view is obstructed.
• Vitreous Tap and Culture: A vitreous tap may be performed to identify the causative microorganism and guide appropriate antibiotic treatment.

Management:

Immediate and aggressive treatment is essential to preserve vision. The management of endophthalmitis includes:

• Intravitreal Antibiotics: Intravitreal injection of antibiotics is the mainstay of treatment to directly target the infection within the eye.
• Topical and Systemic Antibiotics: Concurrent use of topical and systemic antibiotics is often prescribed to manage the infection comprehensively.
• Vitrectomy: In severe cases, a vitrectomy may be necessary to remove the infected vitreous and reduce the microbial load.
• Close Monitoring: Patients with endophthalmitis require close monitoring and follow-up visits to assess treatment response and manage potential complications.

Prevention:

Prevention is key in minimizing the risk of endophthalmitis after cataract surgery. Implementing strict protocols for preoperative, intraoperative, and postoperative care can significantly reduce the incidence of this sight-threatening complication.

Conclusion:

Endophthalmitis after cataract surgery is a serious condition that requires early recognition and immediate intervention to prevent irreversible vision loss. Timely diagnosis, appropriate management, and stringent infection control measures play a crucial role in optimizing the patient's visual outcomes.
