Overview

Laboratory Findings

Retinitis Pigmentosa

[1]

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]
