Background
To assess the outcomes of the various medical and surgical treatment options for malignant glaucoma.
Methods
Design Retrospective, comparative case series.
Participants Twenty-four eyes of 21 patients with malignant glaucoma.
Intervention Nine eyes were treated medically. Twenty-one eyes underwent surgery, 15 of which had the full vitrectomy–(phaco)–iridectomy–zonulectomy procedure.
Main outcome measures Intraocular pressure (IOP), best-corrected visual acuity (BCVA) and number of glaucoma medications were measured.
Results
The relapse rate was 100% after medical therapy, 75% after a Yag laser capsulotomy and a hyaloidotomy, 75% after a conventional vitrectomy and 66% after an anterior vitrectomy in combination with an iridectomy–zonulectomy. All patients who underwent a full vitrectomy combined with an iridectomy and a zonulectomy (and phacoemulsification if phakic) had postoperative relief of malignant glaucoma without relapse within the follow-up period. After this vitrectomy-tunnel technique, the IOP ranged from 10 to 22 mmHg (mean 16 mmHg) after a mean follow-up of 61 days. Mean BCVA improved by 5 Early Treatment Diabetic Retinopathy Study (ETDRS) lines, and mean number of glaucoma medications decreased from two to one.
Conclusion
Complete vitrectomy combined with iridectomy and zonulectomy (and phacoemulsification, if applicable) most successfully managed aqueous misdirection syndrome in our retrospective case series.
