They may be large, solitary lesions, such as those seen following Toxoplasma infection, but sometimes they result in a "spotty" fundus appearance as seen in the presumed ocular histoplasmosis
syndrome (POHS), birdshot chorioretinitis, multifocal choroiditis and pusctete inner choroidopathy (PIC).
T.gondii chorioretinitis may resemble the posterior uveitis of tuberculosis, syphilis, leprosy, or presumed ocular histoplasmosis

Dan Myers, president of Novartis Ophthalmics, North America said, "The fact that Visudyne therapy has demonstrated the ability to stabilize and in some cases improve vision in these pathologic myopia and presumed ocular histoplasmosis
patients is another remarkable success story for this breakthrough therapy.
Presumed ocular histoplasmosis
syndrome (POHS) is a clinical entity that is characterized by small, round, discrete, macular or mid peripheral atrophic (punched out) chorioretinal lesions (histo spots), peripapillary scarring, choroidal neovascularization (CNV), and the absence of anterior uveitis and vitritis.
These cases were diagnosed with myopia, punctate inner choroidopathy (PIC), presumed ocular histoplasmosis
