What is endogenous endophthalmitis?

Endogenous endophthalmitis is a potentially blinding ocular infection resulting from hematogenous spread from a remote primary source. The condition is relatively rare but may become more common as the number of chronically debilitated patients and the use of invasive procedures increase.

What bacteria causes endogenous endophthalmitis?

Endogenous Endophthalmitis Common causes of endogenous bacterial endophthalmitis include S. aureus, B. cereus, and gram-negative organisms, including Escherichia coli, Neisseria meningitidis, and Klebsiella spp. (27, 81, 107, 142).

Is Propionibacterium endogenous?

Propionibacterium acnes endogenous endophthalmitis presenting with bilateral scleritis and uveitis. Sir, Propionibacterium acnes is known to cause delayed-onset postoperative endophthalmitis. Endogenous endophthalmitis, however, is very rare.

What is the most common cause of endophthalmitis?

Chronic post-cataract endophthalmitis is usually caused by Propionibacterium acnes, and presents as a persistent low-grade inflammation in the anterior chamber. Patients present with decreased vision in the affected eye, and half also have eye pain, which is usually mild.

How do you get endogenous endophthalmitis?

Endogenous endophthalmitis results from metastatic spread of the organism from a primary site of infection in the setting of bacteremia or fungemia [40]. Most frequently, the organism reaches the eye through the posterior segment vasculature.

How is endogenous endophthalmitis diagnosed?

Diagnosis

1. Presentation. Patient presentation ranges from asymptomatic to symptoms typical of severe uveitis, including a red, painful eye with photophobia, floaters, or reduced vision.
2. Ocular examination.
3. Differential diagnosis.
4. Diagnostic tests.
5. Vitreous fluid biopsy.

7. Imaging.
8. Bacterial.

What is Propionibacterium acnes route of infection?

SUMMARY. Propionibacterium acnes is known primarily as a skin commensal. However, it can present as an opportunistic pathogen via bacterial seeding to cause invasive infections such as implant-associated infections.

What is P. acnes infection?

• swollen or puffy eyelids.
• decreased, blurred or lost vision.

How does someone get endophthalmitis?

Endophthalmitis is the term used to describe severe inflammation of the tissues inside the eye. The inflammation is typically due to infection by bacteria (eg. Staphylococcus species, Streptococcus species, Gram-negative bacteria) or fungi (eg. Candida, Aspergillus).

Does endogenous endophthalmitis need a more aggressive treatment?

Systemic therapy is used to treat the focus of infection causing the metastatic spread of the organism to the ocular cavity. In mild cases of EE, systemic therapy is the mainstay of treatment. However, in severe cases, systemic therapy is adjuvant to the more aggressive intravitreal administration of drugs.

How is P acne treated?

Penicillin and cephalosporins are effective against clinical P. acnes infection and biofilm in vitro. Combination antibiotic therapy with rifampin and daptomycin may further increase the clinical efficacy of treatment.

Can endophthalmitis be cured?

Endophthalmitis cases can be treated successfully if properly managed, and useful vision can be retained. However, in severe cases of bacterial endophthalmitis, significant vision loss can occur rapidly, despite prompt and proper treatment.

Is endophthalmitis serious?

Endophthalmitis is an uncommon infection of the eyeball. It happens inside the tissues or fluids of the eye due to a bacterial or fungal infection. Endophthalmitis is a medical emergency with a high risk of making you blind. The condition requires prompt diagnosis and treatment from an ophthalmologist.

Endogenous Endophthalmitis: Diagnosis and Treatment. Endogenous endophthalmitis (EE) is an uncommon intraocular infection with potentially devastating visual consequences. An endogenous source is responsible for roughly 2% to 8% of all endophthalmitis. 1 Prompt diagnosis and treatment are essential to obtain the best visual outcomes.

What is the literature on infective endophthalmitis (EE)?

Due to paucity of the disease, literature on EE mostly comprises of case series or single case reports. Unlike exogenous endophthalmitis, demographics, treatment options, and outcome measures in patients with EE have not been studied in large-scale studies. The first case of bacterial EE has been published in 1856 [12].

What causes acute endophthalmitis?

Puncture wounds to the eye are the most likely cause of endophthalmitis. Symptoms usually begin within only a few days of an eye procedure or injury. When symptoms begin quickly like this, it is acute endophthalmitis. The infection can also develop more slowly.

What are the treatment options for endogenous bacterial endophthalmitis?

However, treatment with systemic antibiotics tailored to systemic infection alone is not sufficient, and most patients with severe endogenous bacterial endophthalmitis may require intravitreal antibiotics. In addition, pars plana vitrectomy (PPV) may also be needed for the treatment of endogenous bacterial endophthalmitis. Local therapy
