Objectives To describe the 12-month outcomes of the Xen45 glaucoma stent. Methods Non-comparative retrospective study of all cases who underwent Xen glaucoma surgery in April 2017 or earlier and completed 12 months of follow-up. The primary outcome measures were intraocular pressure (IOP) reduction and number of glaucoma medications at 12 months postoperatively. The secondary outcome measures were surgical complications and the success rate of surgery at 1 year. Success rate was defined according to the multiple IOP thresholds of 15 mmHg, 18 mmHg, and 21 mmHg with all requiring a drop of 20% and no additional glaucoma surgery. Revision or needling of the Xen conjunctival bleb was not considered to constitute a surgical failure. Results Sixty-eight eyes were included in the study. Mean IOP dropped from 22.1 mmHg preoperatively to 14.8 mmHg at 12 months, a 33% drop (p < 0.0001). Mean number of glaucoma medications reduced from 2.9 preoperatively to 1.1 at 12 months (p < 0.0001). In total, 54.4% of cases were back on glaucoma medications by 12 months. Success rate varied from 32.4% when defined as IOP ≤ 15 mmHg and ≥ 6 mmHg and ≥ 20% reduction without medications to 70.6% when defined as IOP ≤ 21 mmHg and ≥ 6 mmHg and ≥ 20% reduction with or without medications. Thirty cases (44.1%) required bleb needling or surgical revision. Conclusions The Xen45 is effective at reducing IOP and glaucoma medication use at 12 months postoperatively. Patients considering this procedure should be warned that by 12 months postoperatively there is a significant chance of requiring postoperative bleb intervention and glaucoma drops.

“…Our results show a decrease of IOP and a reduction of glaucoma medications after MIGS surgery with a low complication rate. The reduced operating time and less frequent follow up and low complication rate compared to trabeculectomy may avoid the need for trabeculectomy in many patients who do not require a very low IOP 27 . This may prove cost effective and these procedures may help health care providers cope with an ever-increasing demand due to an aging population.…”

To compare the safety and efficacy of phacoemulsification combined with ab-interno trabeculectomy (Trabectome) and phacoemulsification combined with I-Stent inject in patients with medically uncontrolled primary open-angle glaucoma (POAG). A retrospective comparative case series. 70 eyes of 66 patients completed 2 years follow up after these treatments performed in 2017–2018. 35 eyes of 33 patients underwent combined Phaco-Trabectome (PT); and 35 eyes of 33 patients underwent combined Phaco-I-Stent inject (Pi). Patient demographics and preoperative characteristics are comparable. A 20% drop in IOP was achieved in 27 eyes (77.14%) in PT group and 28 eyes (80%) in Pi group (p = 0.77). Success rate (target IOP achieved and maintained for 2 years) in advance glaucoma was 25% in PT group and 30.7% in Pi group (p = 0.90). In mild to moderate glaucoma, success rate was 85.71% in PT group and 90% in Pi group (p = 0.67). There was no significant difference between two groups with regards to mean reduction in glaucoma medications and complication rates. Trabectome and I-Stent combined with phacoemulsification are equally efficacious and safe for treating patients with medically uncontrolled mild and moderate primary open-angle glaucoma (POAG). However, they are not an effective treatment for patients with advanced glaucoma.

Intraocular Endoscopy Resolved Tube Occlusion of an Ahmed Glaucoma Valve

We report a case in which intraocular endoscopy clarified the cause of Ahmed glaucoma valve (AGV) failure with a cloudy cornea. A 42-year-old patient with glaucoma underwent AGV implant surgery to treat secondary glaucoma due to chronic iridocyclitis in his left eye. After AGV, he developed bullous keratopathy (BK) in that eye. After Descemet stripping automated endothelial keratoplasty (DSAEK) was performed to treat BK, the intraocular pressure (IOP) increased and early failure of the DSAEK resulted again in a cloudy cornea. We could not precisely detect any cause of AGV failure with ordinary imaging instrumentation. An intraocular endoscope was used to determine that cause, and we found that the fibrous tissue occluded the tube of the AGV. The IOP decreased soon after the tissue was removed. We conclude that intraocular endoscopy was useful for diagnosing AGV failure with BK.
