An 81-year-old Caucasian female was referred with an IOP of 48 mmHg on maximal medications and corneal edema after phacoemulsification. LPIs had been done in the past for PAC glaucoma (PACG). The AC was moderately shallow. An urgent trabeculectomy with intraoperative mitomycin C (MMC) application was done. The following morning, the IOP was 24 mmHg with a flat AC. Malignant glaucoma was suspected, and the patient started on atropine and topical steroids. Nd: YAG laser posterior capsulotomy and hyloidotomy were done, but the AC remained very shallow and the IOP increased to over 40 mmHg. The following week, a ZHV was performed, and the AC deepened intraoperatively []. Postoperatively, while the AC was deep, the IOP remained high and on gonioscopy, the angle was almost completely closed. She was started on dorzolamide-timolol fixed combination eyes drops. On her last visit, 32 months after ZHV, VA was 20/60 and IOP 14 mmHg on medications. There was corneal edema, and the AC remained deep.
A 77-year-old lady with PAC and an IOP of 34 mmHg without medication underwent a phacoemulsification in her right eye. The procedure was difficult with positive pressure and iris prolapsed through the temporal corneal section. 2 weeks postoperatively, IOP rose to 44 mmHg and AC shallowed significantly []. Nd: YAG laser anterior and posterior capsulotomy and hyaloidotomy were done through an inadvertent temporal PI. The AC deepened immediately after the procedure, and the IOP dropped to 34 mmHg. Over the next 2 weeks, the AC was deep, and IOP stabilized at 15 mmHg on topical latanoprost. In the meantime, she also underwent a routine phacoemulsification in the fellow eye. 4 months after her phacoemulsification, the right eye IOP had crept up to 32 mmHg on maximal tolerated medications and AC shallowed. ZHV was performed. Postoperatively, the AC deepened but the IOP control was inadequate, and CMO was noted. The CMO resolved on oral acetazolamide, topical prednisolone 1%, and ketorolac eye drops. However, gradually she developed intolerance to most topical medications. A year after ZHV, she noted blurred vision in the right eye. The IOP was over 30 mmHg, the AC moderately shallow and CMO had recurred. This time 270° cyclodiode laser was done, leading to resolution of the malignant glaucoma. The CMO partially resolved on oral acetazolamide. 2 years after the ZHV, her VA was 20/60 and IOP 22 mmHg without medication.
