SCIENTIFIC CORRESPONDENCE Optical coherence tomography in malignant glaucoma following filtration surgery

Aim: To assess the value of slit lamp adapted optical coherence tomography (OCT) for the management of malignant glaucoma following filtration surgery. Methods: Two patients (three eyes) developed malignant glaucoma following filtration surgery for primary open angle glaucoma (POAG). With slit lamp adapted OCT it was possible to image non-invasively the anterior chamber angle structures during the malignant glaucoma episode, and after pars plana vitrectomy (PPV) with anterior cham-ber reformation. Results: OCT revealed in both patients a markedly decreased anterior chamber angle with extreme shallow-ing of the anterior chamber depth during the acute malig-nant glaucoma phase. This critical closure of the anterior chamber angle resolved after PPV and deepening of the anterior chamber with viscoelastic. After PPV the quantita-tive values of the anterior chamber angle (ACA) and the anterior chamber opening distance (AOD) increased fro
