Nd:YAG laser goniopuncture after deep sclerectomy: outcomes

Purpose: This study aimed to investigate the safety and efficacy of Nd:YAG laser goniopuncture (LGP) in lowering intraocular pressure (IOP) after deep sclerectomy (DS). Methods: We reviewed the outcomes in 258 eyes of 258 consecutive patients who underwent DS or combined phacoemulsification and DS between August 2001 and December 2003. Mitomycin C was used during surgery in 192 eyes (74.4%). Results: Mean follow‐up was 40 ± 11 months after DS and 31 ± 12 months after LGP. Laser goniopuncture was performed in 173 eyes (67.0%). The mean interval between LGP and DS was 10.3 ± 8.7 months. The probability of LGP being performed was 63.1% (95% confidence interval [CI] 57.3–69.4) at 36 months after surgery. At 2 years after LGP, the probability of maintaining IOP < 15 mmHg with a 20% decrease from the pre‐laser IOP and no further glaucoma procedure or medication was 49.7% (95% CI 41.9–57.1). Iris covering the trabeculo‐Descemet’s membrane was the only factor significantly associated with the failure of LGP (hazard ratio 3.0, p < 0.001). Complications observed after LGP included peripheral anterior synechiae in 23 (13.2%), hypotony in seven (4.0%), late acute IOP rise in three (1.7%), delayed bleb leak in one and blebitis in two eyes. Argon laser iridoplasty was performed in 45 (26.0%) and needle revision in 41 (23.7%) eyes. Conclusions: ND:YAG laser goniopuncture is an effective procedure to further lower IOP after DS. An IOP of < 15 mmHg is achieved and maintained for ≥ 2 years in about 50% of cases after a single LGP procedure. There are potentially serious complications associated with the procedure. Regular gonioscopy is recommended following LGP to detect any occlusion of the goniopuncture by the iris.

Abstract：

Objective To evaluate the effectiveness of non-penetrating trabecular surgery (NPTS)combined with reticulated sodium hyaluronate or amnion implant for open angle glaucoma and the value of anterior segment optical coherence tomography (AS-OCT) in the follow-up of NPTS. Methods NPTS was performed on 48 eyes of 42 patients, among whom 37 eyes with reticulated sodium hyaluronate implant, 11 eyes with amnion implant. Main outcome measures included visual acuity, intraocular pressure (IOP), filtering blebs and complications. The follow-up period was 6 to 48 months (mean 18.561 11.49 months). Anterior chamber OCT was undertaken to evaluate the rudimental trabecular reticulum-descement membrane, bleb and scleral cavity of the surgical site on the last follow-up time. Results The IOP was decreased from a mean preoperative value of (38.38±10.60) mmHg to a mean postoperative value of (8.59± 3.51) mmHg and (19.91± 9.28) mmHg on the first day and on the last visit respectively. Postoperative IOP at every visit point was lower than the preoperative value (P <0.01), 36 eyes (75.0%) remained stable visual acuity on the last visit compared with preoperative visual acuity, 5 eyes (10.4%) decreased and 7 eyes (14.6%) elevated. The complications such as inflammation, suprachoroidal hemorrhage and persistent hypotention were not observed except 6 flat chambers and 3 moderate anterior chamber hemorrhage. The completely successful rate on last visit was 26 eyes (54.2%),conditional successful rate was 17 eyes(35.4%)and failure 5 eyes(10.4%).The anterior segment OCT could be observed the rudimental trabecular reticulum-descement membrane,scleral cavity,suprascleral cavity and bled thickness,et al.Conclusions Non-penetrating trabecular surgery with reticulated sodium hyaluronate or amnion implant can effectively lower the IOP without severe complications.Anterior segment OCT is a safe and atraumatic tool for NPTS follow up.

Nd:Yag goniopuncture after deep sclerectomy with collagen implant

BACKGROUND AND OBJECTIVE: To study the need, the safety and the success rate of Nd:Yag goniopuncture in eyes that underwent deep sclerectomy with collagen implant. PATIENTS AND METHODS: The first 100 patients that underwent deep sclerectomy with collagen implant were prospectively followed. Deep sclerectomy with collagen implant is a non-penetrating filtering surgery which allows filtration of aqueous from the anterior chamber to the subconjunctival space through a remaining trabeculo-Descemet's membrane without opening the anterior chamber. Goniopunctures with Nd:Yag laser were performed at the site of surgery when the filtration through the trabeculo-Descemet's membrane was considered to be insufficient with elevated intraocular pressure. The laser treatment was performed using a Lasag 15 gonioscopy contact lens (CGA1). Goniopunctures were performed using the free-running Q-switched mode with an energy ranging from 2 to 4 mJ. RESULTS: Of 100 patients who underwent deep sclerectomy with collagen implant, goniopunctures with Nd:Yag laser were performed in 41 patients (41%). The mean time between deep sclerectomy with collagen implant and goniopuncture was 9.9 months +/-1.2 months (+/-SE). The mean IOP before laser treatment was 22.2 mm +/-7.0 mm Hg and decreased to 12.5 mm +/-5.8 mm Hg immediately after laser treatment and remained stable for the next 2 years of follow-up. The immediate success rate of goniopuncture was 83%. Choroidal detachment occurred in two patients (5%). CONCLUSION: Nd:Yag goniopuncture is an efficient and safe treatment for low filtration through the trabeculo-Descemet's membrane after deep sclerectomy with collagen implant.
