目的 观察晶体过敏性葡萄膜炎（PU）的发病情况及病理学改变。方法 选用新西兰大白兔制作PU动物模型，观察PU发生情况及其病理学变化。结果与结论 PU发生率为70.27%，主要表现为虹膜睫状体血管扩张充血，浆细胞、淋巴细胞、单核细胞及中性粒细胞在该处浸润，早期有嗜酸性粒细胞浸润的非肉芽肿性炎症，无结节样结构，也无组织坏死增生；少量眼则表现为以虹膜睫状体部分组织出血坏死为特征的Arthus型炎症。均符合免疫复合物型炎症的病理改变。
Objective To observe the incidence and pathological changes of crystal allergic uveitis (PU). Methods New Zealand white rabbits were selected to make PU animal model to observe the occurrence and pathological changes of PU. RESULTS AND CONCLUSION: The incidence of PU was 70.27%. The main manifestations were vasodilatation and congestion of iris ciliary body, infiltration of plasma cells, lymphocytes, monocytes and neutrophils there, early eosinophilic infiltration of non-granulation Swollen inflammation, non-nodular structure, and no tissue necrosis; a small amount of eye showed part of the iridocyclitis hemorrhagic necrosis Arthus inflammation. All conformed to the pathological changes of immune complex type inflammation.
