An 83-year-old lady of Indian origin with PAC, bilateral pseudophakia and IOP of 35 mmHg on maximal medical therapy underwent an augmented trabeculectomy with MMC in the right eye. Preoperatively, the AC was moderately shallow in the right eye, and gonioscopy showed a closed angle. The left eye AC was shallow with some peripheral anterior synechiae. A month later, the AC remained shallow, and IOP was 15–20 mmHg on 3 topical glaucoma medications. The patient was referred to the glaucoma clinic where malignant glaucoma was diagnosed, and ZHV preformed. The AC deepened; IOP settled at 15 mmHg and VA was 20/30. 6 months later, she presented with blurred vision for 3 months in the same eye. Her IOP was 23 in the left eye, and the AC was shallow with peripheral irido-corneal touch. Malignant glaucoma was suspected, and she was treated with Atropine 1% drops in that eye. The vision improved to 20/30, the AC deepened, and the IOP was 19 mmHg at 7 days follow-up. However, on a routine follow-up visit 15 months after ZHV, IOP was raised at 34 mmHg and peripheral AC was shallow once more with iridocorneal touch. A repeat ZHV was performed after which the AC deepened []. 2 years after the second ZHV, the IOP was stable at 17 mmHg without medication.
A 63-year-old Caucasian gentleman with schizophrenia was referred to the glaucoma clinic by his optician with bilateral pale optic discs, IOPs over 60 mmHg and vision of counting fingers in both eyes. In both eyes, AC was shallow; the angle completely closed, and the optic discs cupped and pale. A diagnosis of chronic angle closure was made, and bilateral LPIs done. The patient was started on oral acetazolamide and 3 topical glaucoma medications. A month later, the IOP had reduced to 21 mmHg in the right eye. Right eye phacotrabeculectomy under general anesthesia was done with prior explanation of the poor prognosis for visual recovery to the relatives. Intraoperatively, a floppy iris was noted which responded to intracameral phenylephrine. Postoperatively, the AC was shallow and IOP 16 mmHg. A week later, the IOP crept to 23 mmHg, the AC remained shallow with a fibrinous deposit over the pupil. Malignant glaucoma was considered to be the cause and ZHV performed. The AC deepened on the table, but the next morning, the AC was shallow with fibrin covering the pupil and the PI. Nd: YAG laser lysis of the fibrin and anterior hyaloidotomy through the PI was done. The AC deepened immediately. The IOP has been stable over the next 4 years at 18 mmHg without glaucoma medications. However, VA was counting fingers.
