BACKGROUND The diagnosis of ocular toxoplasmosis is mainly based on clinical features. However, ocular fluid testing by PCR may be very helpful for approval or rejection of this etiology. In this study, we utilized a nested-PCR technique, targeting the B1 partial sequence to analyze the aqueous and vitreous samples for evaluating the presence of the Toxoplasma DNA. METHODS Fifty aqueous or vi...

We report the direct genotyping analysis of Toxoplasma gondii in ocular samples collected from 20 patients, as well as associated clinical and epidemiological data. This work was aimed at better understanding the impact of genotypes of Toxoplasma gondii strains on toxoplasmic retinochoroiditis. For this purpose, we studied the aqueous humor (AH) or vitreous humor (VH) of 20 patients presenting ...

Uveitis a vision threatening inflammation of uvea is prevalent worldwide. In the United States uveitis has prevalence of 2.3 million people and causes 10% of all cases of blindness. Uveitis is classified by the ocular structures involved e.g., anterior, intermediate, posterior and panuveitis.0cular TB(Eales’ disease) is common in patients from Indian sub-continent. Frequent uveitis etiologies i...

AIMS To determine whether IgG immunoblotting can improve the diagnosis of ocular toxoplasmosis. METHODS Samples of serum were tested from patients with ocular lesions that could be caused by toxoplasmosis. All such samples from Scotland and Northern Ireland are usually referred to the Scottish Toxoplasma Reference Laboratory. From questionnaires filled out by the clinicians, two groups of ser...

PURPOSE To present unique cystoid changes occurring in patients with ocular toxoplasmosis observed in spectral domain optical coherence tomography (OCT). METHODS Forty-six patients (80 eyes) with a diagnosis of ocular toxoplasmosis, who underwent volume OCT examination between January 2005 and October 2012, were retrospectively collected. Review of clinical examination findings, fundus photog...

Inflammatory diseases of the retina and choroid (chorioretinitis), including those toxoplasmosis etiology usually occur against a background decrease in immunity. We present two clinical cases ocular inflammation at different times after vaccination with Sputnik V. An analysis occurrence pathologic condition to prevent coronavirus infection caused by SARS-CoV-2 virus will help determine criteri...
