前房蛋白性液体Anterior Chamber Proteinaceous Fluid · 眼 · 特殊感觉系统 · NTP ntp-0327
诊断要点:前房中的蛋白性液体应诊断为“眼,前房 - 蛋白性液体”(Eye, Anterior chamber - Proteinaceous fluid),并赋予严重程度分级。
病变描述
前房蛋白性液体(anterior chamber proteinaceous fluid)的特征为前房内积聚均匀淡嗜酸性物质(常含纤维蛋白(fibrin)),其中炎性细胞极少甚至没有(Figure 1、Figure 2)。前房蛋白性液体可压迫虹膜角膜滤角通道和/或邻近小梁网(trabecular meshwork),阻碍房水(aqueous humor)的正常引流,从而导致眼内压升高。(Figure 1 和/或 Figure 2 中的其他眼部病变包括虹膜后粘连(posterior synechiae)、伴矿化的晶状体白内障(lens cataract with mineralization)和/或虹膜炎症(iridial inflammation)。)
诊断与分级建议(NTP 共识)
前房中的蛋白性液体应诊断为“眼,前房 - 蛋白性液体”(Eye, Anterior chamber - Proteinaceous fluid),并赋予严重程度分级。如果前房蛋白性液体是眼内更弥漫性炎症过程的一部分,则无需单独诊断,但应在病理学叙述中描述。

Comment:
Anterior chamber proteinaceous fluid is characterized by intracameral accumulations of homogeneous pale eosinophilic material (often including fibrin) that contains few if any inflammatory cells ( Figure 1 and Figure 2 ). Anterior chamber proteinaceous fluid can compress the iridocorneal filtration angle channels and/or the adjacent trabecular meshwork, impeding normal drainage of aqueous humor with resultant elevations in intraocular pressure. (Other ocular lesions in Figure 1 and/or Figure 2 include posterior synechiae, lens cataract with mineralization, and/or iridial inflammation.)
Recommendation:
Proteinaceous fluid in the anterior chamber should be diagnosed as "Eye, Anterior chamber - Proteinaceous fluid" and assigned a severity grade. If anterior chamber proteinaceous fluid is part of a more dispersed inflammatory process in the eye, it need not be diagnosed separately but should be described in the pathology narrative.
