“…In cases where maintaining the targeted IOP cannot be achieved after nonpenetrating glaucoma surgery, previous studies in the literature have suggested performing laser goniopuncture before topical antiglaucomatous treatment to prevent fibrosis of the TDM and scleral lake collapse. [ 3 8 ] In a previous study that examined the TDM with in vivo confocal microscopy, laser goniopuncture was not effective after TDM fibrosis. [ 9 ]…”

“…Postoperative laser goniopuncture of TDM by neodymium-doped yttrium-aluminum garnet (Nd:YAG) laser reduces its resistance and enhances aqueous outflow by creating one to several tiny holes or slits. [ 3 ] The success rates of nonpenetrating glaucoma surgeries complemented by laser goniopuncture are high, which is similar to those of trabeculectomy. [ 4 ] Conventional 1064 nm Nd:YAG laser has been widely used for this purpose, whereas published results for frequency-doubled 532 nm Nd:YAG selective laser trabeculoplasty (SLT) are currently limited.…”

Purpose:To compare the results of conventional 1064 nm neodymium-doped yttrium-aluminum garnet laser goniopuncture (Nd:YAG-GP) and selective 532 nm Nd:YAG laser (selective laser trabeculoplasty [SLT]) gonioreconditioning (GR) on trabeculo-Descemet's membrane in eyes resistant to viscocanalostomy surgery.Methods:Thirty-eight eyes of 35 patients who underwent laser procedure after successful viscocanalostomy surgery were included in the study. When postoperative intraocular pressure (IOP) was above the individual target, the eyes were scheduled for laser procedure. Nineteen eyes underwent 532 nm SLT-GR (Group 1), and the remaining 19 eyes underwent conventional 1064 nm Nd:YAG-GP (Group 2). IOPs before and after laser (1 week, 1 month, 3 months, 6 months, 1 year, and last visit), follow-up periods, number of glaucoma medications, and complications were recorded for both groups.Results:Mean times from surgery to laser procedures were 17.3 ± 9.6 months in Group 1 and 13.0 ± 11.4 months in Group 2. Mean IOPs before laser procedures were 21.2 ± 1.7 mmHg in Group 1 and 22.8 ± 1.9 mmHg in Group 2 (P = 0.454). Postlaser IOP measurements of Group 1 were 12.1 ± 3.4 mmHg and 13.8 ± 1.7 mmHg in the 1st week and last visit, respectively; in Group 2, these measurements were 13.6 ± 3.7 mmHg and 14.9 ± 4.8 mmHg, respectively. There were statistically significant differences (P < 0.001) in IOP reduction at all visits in both groups; the results of the two groups were similar (P > 0.05). Mean follow-up was 16.6 ± 6.4 months after SLT-GR and 18.9 ± 11.2 months after Nd:YAG-GP.Conclusions:While conventional Nd:YAG-GP and SLT-GR, a novel procedure, are both effective choices in eyes resistant to viscocanalostomy, there are fewer complications with SLT-GR. SLT-GR can be an alternative to conventional Nd:YAG-GP.

“…This procedure is required in almost 50% of patients after NPDS. 11 Although the central corneal thickness is increased after DSAEK, 12 the graft does not reach the filtration area and thickening of the trabeculodescemetic membrane is not expected. Nevertheless, we do not know if goniopuncture would be more frequently required in eyes following DSAEK.…”

Nonpenetrating Deep Sclerectomy For Glaucoma After Descemet Stripping Automated Endothelial Keratoplasty

The purpose of this study was to evaluate the efficacy and safety of nonpenetrating deep sclerectomy (NPDS) in 3 consecutive eyes with preexisting and uncontrolled glaucoma after Descemet stripping with automated endothelial keratoplasty (DSAEK).NPDS with intrascleral implant and topical adjunctive intraoperative mitomycin C (0.2 mg/mL 1 minute) was performed.Intraocular pressure (IOP) and number of glaucoma medication were registered before and after NPDS with at least 1-year follow-up. Intraoperative and postoperative complications were also registered.Before NPDS, IOP was 18 mm Hg in 1 patient and 32 mm Hg in the other 2 patients. Four antiglaucoma drugs were used in 2 cases and 3 in the other one. At 1 year after NPDS, all the patients had an IOP ≤18 mm Hg. Two patients required postoperative antiglaucoma medications (1 drug in 1 case and 2 drugs in the other one). Neodymium-doped yttrium aluminum garnet laser goniopuncture was needed in 2 patients and it had to be repeated in 1 of them. No complications related to NPDS were observed. A corneal graft rejection was observed 5 months after NPDS in 1 case that resolved without sequelae with intensive corticosteroid eye-drop therapy.NPDS could be a safe and successful alternative to conventional filtration surgery after DSAEK in eyes with uncontrolled glaucoma. Larger series and a longer follow-up would be necessary to set the actual role of surgery in DSAEK patients.

“…Laser goniopuncture employs tiny holes by using an Nd:YAG laser. It augments aqueous outflow through the trabeculo-Descement window when greater IOP lowering is required or when a bleb begins to fail, with no need of additional incisional surgery [ 57 , 58 ]. In a study of 258 eyes undergoing deep sclerectomy or com-bined cataract and deep sclerectomy, a single goniopuncture procedure achieved a 20% IOP reduction, and was stable for at least 2 years in about 50% of cases [ 59 ].…”

“…Laser goniopuncture complications include hyphema, iritis, peripheral synechia, iris incarceration, hypotony and late bleb leak, however, complication rates are generally low. Goniopuncture can be easily performed in office settings and appears not to interfere with the high safety profiles of nonfiltering glaucoma surgeries [ 57 ].…”

There has been tremendous progress in the past decades in the utilization of lasers for treating patients with glaucoma. This article reviews the use of lasers in different areas of glaucoma, including the shift from argon laser trabeculoplasty (ALT) to selective laser trabeculoplasty (SLT), laser trabeculoplasty as an initial treatment for glaucoma, new laser trabeculoplasty procedures under investigation, and other recent laser treatment modalities such as endoscopic cyclophotocoagulation and laser-assisted deep sclerectomy.
