ICD-10: H44.00

Unspecified purulent endophthalmitis, classified under ICD-10 code H44.00, is a serious ocular condition characterized by inflammation of the interior of the eye, specifically the vitreous and/or aqueous humor, due to a purulent (pus-forming) infection. This condition can arise from various sources, including post-surgical complications, trauma, or hematogenous spread of infection.

Clinical Description

Definition

Endophthalmitis is an inflammatory condition of the intraocular tissues, often resulting from infectious agents. The term "purulent" indicates the presence of pus, which is a thick fluid composed of white blood cells, dead tissue, and bacteria. Unspecified purulent endophthalmitis refers to cases where the specific causative organism is not identified or documented.

Etiology

The etiology of purulent endophthalmitis can vary widely, but common causes include:
- Postoperative infections: Following cataract surgery or other intraocular procedures, where bacteria may enter the eye.
- Traumatic injuries: Penetrating injuries to the eye can introduce pathogens directly into the intraocular space.
- Systemic infections: Bacteria from other parts of the body can spread to the eye through the bloodstream.

Symptoms

Patients with unspecified purulent endophthalmitis may present with a range of symptoms, including:
- Severe eye pain: Often described as intense and persistent.
- Decreased vision: Patients may experience a rapid decline in visual acuity.
- Redness and swelling: The conjunctiva may appear injected, and there may be swelling around the eye.
- Photophobia: Increased sensitivity to light.
- Discharge: Purulent discharge may be noted, indicating the presence of infection.

Diagnosis

Diagnosis typically involves a comprehensive eye examination, including:
- Visual acuity testing: To assess the extent of vision loss.
- Slit-lamp examination: To evaluate the anterior segment and look for signs of inflammation or infection.
- Fundoscopy: To examine the retina and vitreous for signs of endophthalmitis.
- Microbiological testing: Cultures of intraocular fluid may be performed to identify the causative organism, although this may not always be possible in unspecified cases.

Treatment

Management of unspecified purulent endophthalmitis often requires urgent intervention, which may include:
- Intravitreal antibiotics: Administered directly into the eye to combat infection.
- Systemic antibiotics: Depending on the severity and source of the infection.
- Surgical intervention: In some cases, vitrectomy may be necessary to remove infected tissue and improve outcomes.
