“…The impact of previous surgeries on GATT prognosis remains unclear [18][19][20][21]. In our cohort, eyes with prior ocular surgery history exhibited an inferior GATT success rate, likely attributed to scarring, in ammation, or brotic changes within the TM after previous trabeculectomy (5 eyes) or intraocular environmental disturbance caused by other ocular surgery (one eye with lens subluxation) [20,[22][23][24].…”

Background: This retrospective study aimed to evaluate the efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in Chinese patients with primary congenital glaucoma (PCG) and identify factors influencing surgical success. Methods: Fourteen patients (24 eyes) diagnosed with PCG who underwent gonioscopy-assisted transluminal trabeculotomy were recruited, and data on intraocular pressure (IOP), antiglaucoma medication, surgery-related complications, and additional treatments were collected during preoperative and postoperative visits. Surgical success was defined as IOP ≤ 21 mmHg and a reduction of >30% from baseline, with (partial success) or without (complete success) antiglaucoma medication. Results: Mean preoperative IOP was 30.41 ± 6.09 mmHg. At the final visit, mean IOP reduction was 16.1 ± 9.1 mmHg (52%), and 19 of 24 eyes were topical medication–free. IOP was significantly decreased at each postoperative visit compared with baseline (P < 0.05 for all time points). Cumulative proportions of complete and partial success were 79.2% and 95.8%, respectively, at three years postsurgery. Patients without prior antiglaucoma procedures, without postoperative IOP spikes, and those undergoing complete trabeculotomy exhibited improved surgical prognosis. No permanent vision-threatening complications occurred in the 24 eyes by the end of the respective follow-ups. Conclusion: Gonioscopy-assisted transluminal trabeculotomy emerged as a safe and effective procedure for PCG treatment, characterized by outstanding IOP reduction efficacy and high surgical success rates.

“…Lee et al. demonstrated that subvisible exposures (250–350 mW power) in PSLT resulted in thinning of the uveal meshwork and denudation of trabecular endothelial cells in cat eyes. Compared to ALT‐treated eyes, there was substantially less thermal damage and trabecular beams were not disrupted.…”

“…Unlike ALT, the IOP‐lowering effect of PSLT was achieved without visible damage to TM (Lee et al. ). Like SLT, it provides uniform coverage of TM, but with some notable differences in the treatment parameters.…”

“…2 ) uses short pulse durations (10 to 20 ms) and predetermined patterns of spots, which results in reduction of thermal diffusion and surrounding tissue damage. In a recent experimental study, PLT resulted in less thermal damage than ALT, but did not effectively prevent late scarring of the trabecular meshwork [ 37 ]. A pilot study found a 24% reduction in IOP, without IOP spikes or inflammation, over 6 months of follow-up [ 38 ].…”

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.

Morphologic Changes in Trabecular Meshwork after Patterned and Argon Laser Trabeculoplasty in Cats

Abstract: When used at sub-threshold power, PLT caused less thermal damage to the trabecular meshwork than ALT. However, it did not effectively prevent late scarring of the trabecular meshwork in cats.
