Sarcoidosis is a multi-system granulomatosis of unknown etiology, defined by the presence of epithelioid and gigantocellular granulomas, without caseous necrosis. Ocular sarcoidosis manifests mainly as bilateral granulomatous anterior uveitis. Occlusion of the central retinal vein in sarcoidosis is a rare manifestation, which is the particularity of our observation. We report the case of a patient presenting with unilateral central retinal vein occlusion associated with granulomatous anterior uveitis on the same side. Systemic manifestations and further investigations led to the diagnosis of sarcoidosis., (© 2024 Imen Chabchoub et al., published by Sciendo.)

Punctuate Outer Retinal Toxoplasmosis (PORT) is a rare variant of toxoplasma chorioretinitis. We report the case of a 21-year-old patient presenting with visual blur of the left eye (LE). The examination found a corrected visual acuity (VA) at 3/10 th , a quit anterior segment and a 1+ vitreous haze. Fundus examination showed a suprafoveolar yellowish-white lesions associated to multiple peripheral atrophic and pigmented ones. Visual acuity of the right eye was 10/10 th with a calm anterior segment. Fundus examination depicted an upper temporal cicatricial pigmented lesion. Multimodal imaging of LE objectified a PORT. The patient received antibiotic and corticosteroids with favorable clinical and functional outcome. Final VA reached 10/10 at day ten. This case illustrates the importance of multimodal imaging in the differentiation of PORT from the white dots syndrome and other unilateral retinitis., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright: Malek Kharrat et al.)
