Understanding Parasitic Endophthalmitis

Parasitic endophthalmitis is an inflammatory condition of the eye caused by parasitic infections, which can lead to severe vision impairment or loss if not diagnosed and treated promptly. The term "unspecified" indicates that the specific type of parasite causing the infection has not been identified, while "bilateral" signifies that both eyes are affected.

Diagnostic Criteria

1. Clinical Symptoms

• Visual Disturbances: Patients may report blurred vision, decreased visual acuity, or complete vision loss.
• Ocular Pain: Discomfort or pain in the eyes can be a significant symptom.
• Redness and Swelling: Inflammation of the conjunctiva and surrounding tissues may be observed.
• Photophobia: Increased sensitivity to light is common in cases of endophthalmitis.

2. Patient History

• Exposure History: A thorough history of potential exposure to parasites, such as travel to endemic areas, contact with contaminated water, or exposure to animals, is crucial.
• Systemic Symptoms: Any accompanying systemic symptoms, such as fever or malaise, should be noted, as they may indicate a more widespread infection.

3. Ophthalmic Examination

• Fundoscopy: A detailed examination of the retina and vitreous using an ophthalmoscope can reveal signs of inflammation, such as vitritis (inflammation of the vitreous body) and retinal lesions.
• B-scan Ultrasound: This imaging technique can help visualize the internal structures of the eye and assess for any abnormalities that may not be visible through direct examination.

4. Laboratory Tests

• Microbiological Cultures: Samples from the vitreous or aqueous humor may be taken for culture to identify the specific parasite responsible for the infection.
