To describe clinical and multimodal imaging characteristics of punctate inner retinal toxoplasmosis (PIRT) as an atypical presentation of ocular toxoplasmosis (OT).
Retrospective review of OT cases with PIRT lesions and review of the literature. We describe five cases (6 eyes).
PIRT lesions were seen adjacent to active/healed toxoplasma retinochoroiditis. The appearance of PIRT was creamy yellowish-white, inner retinal, punctate, and sub-centimetric lesions. The depth of these lesions on optical coherence tomography was till the outer plexiform layer. Co-existing punctate outer retinal toxoplasmosis (PORT) was found in three eyes and recurrent retinochoroiditis in three. The fate of PIRT was resolution with minimal retinal thinning or progression to a full-thickness retinochoroiditis.
PIRT was noted in association with typical toxoplasma retinochoroiditis and PORT lesions, and had equal chances of resolution or progression to full-thickness lesions.
描述斑点状内层视网膜弓形虫病（PIRT）的临床和多模态影像学特征，作为眼部弓形虫病（OT）的不典型表现。
回顾性分析 PIRT 病变的弓形虫病病例，并复习文献。我们共描述了 5 例（6 只眼）患者。
PIRT 病变位于活动性/愈合性弓形虫性视网膜炎旁。PIRT 的表现为奶油黄白色、视网膜内、点状、亚厘米大小的病变。这些病变在光学相干断层扫描上的深度达外丛状层。3 只眼同时存在点状外层视网膜弓形虫病（PORT），3 只眼存在复发性视网膜炎脉络膜炎。PIRT 的结局是消退，伴有最小程度的视网膜变薄，或进展为全层视网膜炎脉络膜炎。
PIRT 与典型弓形虫性视网膜炎和 PORT 病变相关，其消退或进展为全层病变的可能性相等。
