A 34-year-old man was evaluated for posttraumatic endophthalmitis with hypopyon. A previous CT scan of the orbit along with B-scan ultrasonogram failed to confirm the presence of an intraocular foreign body. Nevertheless, at the time of vitrectomy, a polyvinyl chloride (PVC) plastic foreign body was encountered. The atypical posttraumatic uveitis that developed was apparently secondary to the PVC material, as the inflammation cleared rapidly following removal of the foreign body. This case illustrates the necessity for maintaining a high level of suspicion for the possibility of an intraocular foreign body in the event of ocular trauma, even in the presence of unconfirming ancillary tests.
一名34岁男性因创伤后脓性前房积脓性眼内炎接受评估。先前的眼眶CT扫描和B超检查未能证实眼内有异物。然而，在玻璃体切除术中发现了一个聚氯乙烯（PVC）塑料异物。所发生的非典型创伤后葡萄膜炎显然是由PVC材料引起的，因为异物取出后炎症迅速消退。该病例说明，即使辅助检查结果不支持，在发生眼外伤时仍需高度怀疑眼内有异物的可能性。
