目的介绍一种发生于玻璃体切除术后的非感染性前房积脓现象，即假性前房积脓。方法收集我中心收治的需行玻璃体切除术的连续病例１２５０例，其中各种原因引起的玻璃体积血４１８例。术后发生假性前房积脓者７例，均为玻璃体积血者。主要治疗方法是前房冲洗及其自然吸收。结果假性前房积脓发生于术后３～５天，呈泥沙样沉积，局部抗生素及激素加强治疗无效。眼内穿刺行涂片、细菌和真菌培养未发现病原体。患者无疼痛等自觉症状及刺激征。随访时３例视力在０．０５以上。结论玻璃体积血行玻璃体切除术后可能出现假性前房积脓，须与眼内感染相鉴别。

Psudohypopyon after vitrectomy for vitreous himorrhage

Objictive To describe an uninfective hypopyon phenomenon after vitrectomy(pseudohypopyon).Methods 1250 cases (consecutive cases) who had undergone vitrectomy were collected.Among them,418 cases were vitreous hemorrhage due to various disorders.Pseudohypopyon was found in 7 cases.All of them were the patients with vitreous hemorrhage.Results Pseudohypopyon occurred in 3 5 days after vitrectomy,like precipitation of muddy sand;systemic and local treatment of antibiotic and steroid were not effective,intraocular centesis for smear and culture could not find any germs;and the patients were painless and no irritation in the eyes.The relatively effective method for this kind of hypopyon was paracentesis of anterior chamber and its natural absorption.After afollow up period of 3 months,3 cases obtained the vision above 0.05.Conclusion Pseudo hypopyon might happen after vitrectomy for vitreous hemorrhage,and it should be differentiated from infective ophthalmitis.
