[Pseudohypopyon after vitrectomy for vitreous hemorrhage].
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.
