Toxoplasmosis is a common ophthalmic disorder and is said to cause a considerable number of cases of posterior ocular inflammation. Different investigators have considered toxoplasmosis to be the cause of 16-70% of cases of posterior uveitis.l2 Subretinal neovascularisation is a clinical finding. It is seen in a variety of eye diseases, with the list of associated ocular disorders growing as fl...

PURPOSE Laboratory diagnosis of ocular toxoplasmosis, the major cause of posterior uveitis worldwide, can be improved. Heat shock protein (Hsp) 70 is involved in cellular infection by Toxoplasma gondii but also in the immune response to this parasite. The authors postulate that infected patients may exhibit serum IgG anti-Hsp70.1 antibodies and that determining the presence of these antibodies ...

Gene amplification by the polymerase chain reaction (PCR) is useful in ophthalmic diagnosis since it enables exceedingly small amounts of nucleic acid to be detected in ocular samples. Studies have indicated a potential for the use of PCR on ocular specimens to assist the clinical diagnosis of ocular toxoplasmosis.' We describe a case in which the technique was used in the diagnosis of acquired...

Toxoplasmosis is a relatively rare complication in renal transplant patients and can pose diagnostic challenges, especially when it manifests as an ocular inflammation. Authors hereby report an unusual case of a 57-year-old male who developed retinochoroidal toxoplasmosis after 15 years of renal transplant, the diagnoses of which were challenging as the patient was also a known case of cerebral...

Ocular toxoplasmosis is a common vision-threatening disease in Indonesia. Diagnosis of this disease is based on characteristic ophthalmoscopic appearances and laboratory findings. Between 1985 and 1989, the authors retrospectively evaluated 41 children under 12 years of age. Thirteen cases had retinal lesions suspected to be toxoplasmosis but the laboratory findings were negative. The remaining...

Toxoplasmosis was the most common cause of primary retinochoroiditis. The majority of cases of ocular toxoplasmosis were congenital. However, cases of acquired ocular toxoplasmosis have been reported. The clinical manifestations of congenital ocular toxoplasmosis were choroidal coloboma, strabismus, nystagmus, ptosis, microphthalmia, cataract and enophthalmia. The purpose of this study was to d...

PURPOSE To report the findings of indocyanine green angiography performed in patients with recurrent ocular toxoplasmosis. METHODS Institutional prospective analysis of 23 eyes from 23 immunocompetent patients with recurrent ocular toxoplasmosis aged between 17 and 41 years. These patients underwent a complete ocular examination including indocyanine green angiography. RESULTS Multiple hypo...

AIM To assess functional impairment in terms of visual acuity reduction and visual field defects in inactive ocular toxoplasmosis. METHODS 61 patients with known ocular toxoplasmosis in a quiescent state were included in this prospective, cross-sectional study. A complete ophthalmic examination, retinal photodocumentation and standard automated perimetry (Octopus perimeter, program G2) were p...

BACKGROUND ROP16 is a protein kinase of Toxoplasma gondii identified in the mouse model as a virulent marker, but it is unknown whether this finding is relevant in human toxoplasmosis. METHODS We obtained the Toxoplasma ROP16 locus DNA sequence in samples from 12 patients with ocular toxoplasmosis, 1 sample from a patient with congenital toxoplasmosis, 22 samples from soldiers operating in th...

A large amount of research has been done on toxoplasmosis in the last 30 years, and the world-wide incidence of the infection, and its clinical manifestations, are recognized and documented in an extensive literature. New discoveries concerning the life-cycle of the organism (Frenkel, I970; Hutchison, Dunachie, Siim, and Work, I970) promise to solve many of the problems of the transmission of i...
