Presumed Acquired Ocular Toxoplasmosis

Active ocular toxoplasmosis in Turkish patients: a report on 109 cases

“…The disease is uncommon after the age of 50 years. Several authors have reported that older patients have more-severe disease with multiple and/or larger active lesions [18][19][20][21][22]. The oldest patient in the present series was 54 years old and did not have atypical or more-severe disease.…”

Outbreak of Acquired Ocular Toxoplasmosis Involving 248 Patients

“…18 The capture ELISA technique used to detect IgM antibodies has a high specificity and does not give false-positive results in the presence of high T gondii IgG levels, antinuclear antibodies, or rheumatoid factor. 12 In our series, serum was positive for T gondii IgM antibodies in all 198 cases for whom the tests were done. It was noticeably absent in patients with features of recurrent ocular toxoplasmosis seen in the previous 18 months.…”

“…Most patients presented with solitary, discrete, active focus of retinochoroiditis with no preexisting scars, consistent with acquired ocular toxoplasmosis. [8][9][10]12,16 The mean age of 40.47 years in our patients is higher than those with recurrent congenital disease in whom toxoplasmic retinochoroiditis occurs more frequently in the second and third decades of life. 17 However, the mean age of our patients is lower than that reported in 2 other case series of acquired ocular toxoplasmosis reported by Remington and Montoya 7 (mean, 50.2 years) and by Burnett et al (mean, 54 years).…”

Frequency of specific anti-Toxoplasma gondii IgM, IgA and IgE in Colombian patients with acute and chronic ocular toxoplasmosis

“…Montoya and Remington (1996) suggest that the congenital form of ocular toxoplasmosis have a more guarded prognosis than postnatally acquired toxoplasmosis but we found that ocular toxoplasmosis was compli-cated with a persistent vitritis in our patient with serological evidence of recently acquired toxoplasmosis. The study of Ronday et al (1995) also found severe complications in six of eigth patients with presumed acquired ocular toxoplasmosis. It would be important to test whether Colombian strains of T. gondii are different to strains from other geographical regions and if different strains have different pathogenic properties.…”
