Summary

Ocular toxoplasmosis is the most common cause of infectious uveitis worldwide. The diagnosis of ocular toxoplasmosis is primarily clinical when it is a typical presentation .With an atypical presentation in the fundus, parasitological diagnosis is a decisive contribution, as well as multimodal imaging. We investigate on vitreal, retinal, and choroidal morphologic changes in active and scarred toxoplasmosis lesions using swept source optical coherence tomography.

Detailed description

A retrospective analysis of patients diagnosed with ocular toxoplasmosis was conducted. The patients were examined at ophthalmology service of Farhat Hached Hospital in Sousse Tunisia between January 2002 and December 2017. Complete ophthalmologic examination and OCT were done at the initial visit and during follow-up.

Conditions

• Ocular Toxoplasmosis

Type	Name	Description
DIAGNOSTIC_TEST	Spectral optical coherence tomography	Swept-source optical coherence tomography (SS-OCT) is the latest milestone in retinal and choroidal imaging. Because its wavelength of 1050 nm, which is superior to the 840 nm of spectral domain optical coherence tomography (SD-OCT), it is able to overcome ocular opacities such as cataracts and vitritis, wich allows retinal and choroidal visualization of eyes whose fundus is not clearly visible. Consequently , SS-OCT allows visualization of the retinal and choroidal vascular networks, even in eyes with medium opacity
