PURPOSE
To report the clinical and optical coherence tomography features of spherical deposits associated with recurrent toxoplasmic chorioretinitis.
METHODS
Case report.
RESULTS
Atypical, 100 microm to 150 microm, greyish deposits appeared along retinal arteries and veins as well as on the vitreoretinal interface in the macula of a 44-year-old Caucasian woman while she was being treated for recurrent toxoplasmic chorioretinitis with antiparasitic drugs and subconjunctival injection of betamethasone. They disappeared progressively with the systemic use of corticosteroids. Their clinical course was nicely documented by optical coherence tomography.
CONCLUSIONS
Greyish spherical deposits on the vitreoretinal interface have been previously described as inflammatory reactions in asymptomatic human T-lymphotropic virus type I (HTLV-1) carriers and in patients with HTLV-1-associated uveitis. For the first time, optical coherence tomography (OCT) provided clinical correlation of this unusual presentation of toxoplasmic chorioretinitis.
目的
报告与复发性弓形体性脉络膜视网膜炎相关的球形沉积物的临床及光学相干断层扫描特征。
方法
病例报告。
结果
一名44岁白种女性在使用抗寄生虫药物及结膜下注射倍他米松治疗复发性弓形体性脉络膜视网膜炎时，在其黄斑区的视网膜动静脉以及玻璃体视网膜界面出现了非典型的、100微米至150微米的灰色沉积物。随着全身使用皮质类固醇，这些沉积物逐渐消失。光学相干断层扫描很好地记录了它们的临床病程。
结论
玻璃体视网膜界面上的灰色球形沉积物先前已被描述为无症状的I型人类嗜T淋巴细胞病毒（HTLV-1）携带者及HTLV-1相关性葡萄膜炎患者的炎症反应。光学相干断层扫描（OCT）首次提供了这种弓形体性脉络膜视网膜炎异常表现的临床关联。
