Overview
Laboratory Findings
Retinitis Pigmentosa
Infectious Agents
Cytomegalovirus
- Polymerase chain reaction (PCR) testing in particular regions
- Usually detectable in blood and other bodily fluids[2]
Tuberculosis
- Testing methods for ocular tuberculosis include:
- Positive purified derivative skin testing
- Interferon-gamma release assay (QuantiFERON Gold TB Test)
- Isolation of acid-fast bacilli[2]
Fungal
- Testing methods for identification of a fungal infectious agent largely depend on microscopic examination of infected area.
- Localized infections may display hyphae and typically, easily identifiable lesions.[2]
Toxoplasmosis
- Serologic testing (ELISA)[2]
Syphilis
- Serologic testing
- Rapid plasma reagin (RPR) testing
- Fluorescent treponemal antibody absorption testing (FTA-ABS)[2]
