Overview

Differential Diagnosis of Cytomegalovirus infection

Cytomegalovirus Retinitis

Cytomegalovirus retinitis must be differentiated from the following infectious causes of retinitis:

Infectious Agent Clinical Manifestations
Cytomegalovirus
  • Physical evidence of a cytomegalovirus presence in one of both eyes will generally clinical present in the form of lesions, adjacent retinal vessels.
  • These lesions may impinge upon the fovea and the optic nerve. Furthermore they are usually discovered in close proximity to both.
  • Further extending lesions may be present in close proximity to the vortex veins as well as the ora serrata.[1]
Tuberculosis
Fungal

Candida albicans

Aspergillus fumigatus

  • Yellow subretinal infiltrates
  • Retinal infiltrates
  • Fungal hyphae are located throughout the eye - suggestive of pulmonary involvement[1]

Cryptococcus neoformans

Toxoplasmosis
  • Localized areas of infiltrate
  • Active lesions are adjacent to initial scarring[1]
Syphilis
