Treatment Outcomes in Malignant Glaucoma
Purpose:
To report treatment outcomes in malignant glaucoma.
Design:
Retrospective case series.
Participants:
Twenty-eight eyes of 26 patients who were treated for malignant glaucoma between 1991 and 2009.
Methods:
Malignant glaucoma was diagnosed based on the presence of a shallow or flat central and peripheral anterior chamber in the presence of patent iridotomy, with intraocular pressure (IOP) of 22 mmHg or more after any intraocular surgery. The treatment algorithm included antiglaucoma medications and cycloplegics as first-line methods; the second-line therapy in pseudophakic eyes was laser hyaloidotomy, followed by vitrectomy-hyaloidotomy-iridectomy (VHI) (Read more...)
