[Malignant glaucoma following trabeculectomy--case report].

PURPOSE: Presentation of two cases of malignant glaucoma following filtration surgery.

MATERIAL AND

METHODS

Two patients with primary angle closure glaucoma has been treated with trabeculectomy. Flat anterior chamber, elevated IOP and the presence of patent irydectomy has been diagnosed 1 and 5 weeks after operation respectively. First patient in spite of peripheral irydectomy, medication and pars plana vitrectomy had high IOP and flat anterior chamber and has lost her sight. Second patient has improved after pharmacological treatment.

CONCLUSIONS

Malignant glaucoma is a rare, but very serious complication after trabeculectomy. A very close and regular postoperative examination is necessary for a quick pharmacological or operative intervention.
