A 32-year-old man with AIDS has a CD4+ T-cell count of 40/mm. He complains of a gradual onset of decreased vision in his right eye over the past few days. He is afebrile and has temporal wasting. There is a thick, cheesy, white exudate on his tongue and oropharynx, and there are deficits in the acuity and the visual fields of his right eye. The remainder of the cranial nerve examination is normal. Infection with which of the following pathogens is the most likely cause of his decreased vision?
(A) Candida albicans
(B) Cytomegalovirus (CMV)
(C) Herpes simplex virus 1 (HSV-1)
(D) Mycobacterium avium-intracellulare (MAI)
(E) Pneumocystis carinii
(F) Toxoplasmosis
