Malignant glaucoma after Ahmed valve implant

ABSTRACT

To report and describe the clinical presentation of malignant glaucoma after Ahmed glaucoma valve implant [AGVI] in 2 patients. Chart review of 2 patients who developed malignant glaucoma after AGVI at the King Khaled Eye Specialist Hospital, Riyadh. Both patients developed high intraocular pressure [IOP] associated with axial shallowing of the anterior chamber despite patent iridotomies and normal posterior segment anatomy following AGVI surgery. Both of them did not respond to medical or laser treatment. However, the anterior chamber deepened and the IOP was controlled in both cases after pars plana vitrectomy and anterior chamber reformation. Malignant glaucoma can develop after AGVI. Successful clinical outcomes can be achieved with posterior segment surgery
