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, 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 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.
点状外层视网膜弓形体病(PORT)是弓形体脉络膜视网膜炎的一种罕见变异型。我们报告一例21岁患者,其左眼出现视力模糊。检查发现矫正视力(VA)为3/10,眼前节正常,玻璃体轻度混浊(1+)。眼底检查显示黄斑上方有黄白色病变,伴有多个周边萎缩性和色素性病变。右眼视力为10/10,眼前节平静。眼底检查发现颞上方有陈旧性色素沉着病变。对左眼进行的多模态成像确诊为PORT。患者接受了抗生素和皮质类固醇治疗,临床和功能预后良好。第十天时最终视力达到10/10。该病例说明了多模态成像在区分PORT与白点综合征及其他单侧视网膜病变中的重要性。
