Objective: To describe an uninfective hypopyon phenomenon after vitrectomy (pseudohypopyon).
Methods: 1,250 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 a follow-up period of 3 months, 3 cases obtained the vision above 0.05.
Conclusions: Pseudo-hypopyon might happen after vitrectomy for vitreous hemorrhage, and it should be differentiated from infective ophthalmitis.
