ABSTRACT

Purpose

To describe clinical and multimodal imaging characteristics of punctate inner retinal toxoplasmosis (PIRT) as an atypical presentation of ocular toxoplasmosis (OT).

Methods

Retrospective review of OT cases with PIRT lesions and review of the literature. We describe five cases (6 eyes).

Results

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.

Conclusion

PIRT was noted in association with typical toxoplasma retinochoroiditis and PORT lesions, and had equal chances of resolution or progression to full-thickness lesions.

点状视网膜内弓形虫病：病例系列和文献回顾

摘要

目的

描述点状视网膜内弓形虫病 (PIRT) 作为眼弓形虫病 (OT) 的非典型表现的临床和多模式成像特征。

方法

OT伴PIRT病灶的回顾性分析及文献复习。我们描述了五个案例（6 只眼睛）。

结果

PIRT 病变与活动性/治愈的弓形虫视网膜脉络膜炎相邻。PIRT外观呈乳白色、内视网膜、点状、亚厘米级病变。光学相干断层扫描这些病变的深度一直到外丛状层。在三只眼睛中发现了共存的点状外视网膜弓形虫病（PORT），在三只眼睛中发现了复发性视网膜脉络膜炎。PIRT 的命运是消退，视网膜变薄或进展为全层视网膜脉络膜炎。

结论

PIRT 与典型的弓形虫视网膜脉络膜炎和 PORT 病变有关，并且有相同的机会消退或进展为全层病变。
