The use of GDD has increased and that of trabeculectomy has concurrently decreased over the past 2 decades.

Laser Peripheral Iridotomy in Primary Angle Closure: A Report by the American Academy of Ophthalmology.

Laser peripheral iridotomy increases angle width in all stages of primary angle closure and has a good safety profile.

Peripapillary Retinal Nerve Fiber Layer Vascular Microcirculation in Eyes With Glaucoma and Single-Hemifield Visual Field Loss.

Reduced RNFL microcirculation was detected in the normal hemisphere of eyes with glaucoma, with strong correspondence with VF loss and RNFL thinning.

Primary Angle-Closure Disease Preferred Practice Pattern®.

Automated Detection of Glaucoma With Interpretable Machine Learning Using Clinical Data and Multimodal Retinal Images.

The accuracy of our model suggests distinct sources of information in each imaging modality and in the different clinical and demographic variables.

Spectral-Domain OCT: Helping the Clinician Diagnose Glaucoma: A Report by the American Academy of Ophthalmology.

Structural glaucomatous damage can be detected by SD OCT. Optic nerve, RNFL, and macular parameters can help the clinician distinguish the anatomic changes that are associated with patients with glaucoma when compared with normal subjects.

The Effect of Anti-Vascular Endothelial Growth Factor Agents on Intraocular Pressure and Glaucoma: A Report by the American Academy of Ophthalmology.

Intravitreal injection of anti-VEGF agents results in an immediate and transient increase in IOP.

The Primary Tube Versus Trabeculectomy Study: Methodology of a Multicenter Randomized Clinical Trial Comparing Tube Shunt Surgery and Trabeculectomy with Mitomycin C.

Practice patterns vary in the surgical management of glaucoma, and opinions differ among surgeons regarding the preferred primary operation for glaucoma.

Primary Open-Angle Glaucoma Suspect Preferred Practice Pattern®.

Comparing Treatment Outcomes from the Tube Versus Trabeculectomy and Primary Tube Versus Trabeculectomy Studies.

Differences in patient characteristics between the PTVT and TVT Studies, including the level of preoperative intraocular pressure, contributed to the differences in surgical failure rates in each trial.

Visual Field Outcomes in the Tube Versus Trabeculectomy Study.

Slow rates of VF loss were observed after randomized surgical treatment in the TVT Study, but no significant difference in the rate of VF loss was seen after tube shunt implantation and trabeculectomy with MMC.

Incidence of and Risk Factors for Steroid Response After Cataract Surgery in Patients With and Without Glaucoma.

Although glaucoma patients were 3.72 times more likely to have steroid response after uneventful cataract surgery, the incidence of steroid response with prednisolone acetate 1% was relatively low after phacoemulsification in both nonglaucoma and glaucoma eyes.

Macular Vascular Microcirculation in Eyes With Open-angle Glaucoma Using Different Visual Field Severity Classification Systems.

Macular vascular microcirculation metrics detected by OCTA correlate with disease severity in glaucomatous eyes. VF CMS, calculated from only 12 tested central 10-degree points, correlated best with macular OCTA.

Refractive Outcome of Cataract Surgery in Eyes With Prior Trabeculectomy: Risk Factors for Postoperative Myopia.

Low posttrabeculectomy IOP (≤9 mm Hg) is a risk factor for significant myopic surprise when undergoing subsequent cataract surgery despite using laser interferometry to measure ocular biometry and later generation formulae to determine IOL power.

Intraocular Pressure After Phacoemulsification in Open-angle Glaucoma Patients With Uncontrolled or Marginally Controlled Glaucoma and/or With Severe Visual Field Loss.

Phacoemulsification resulted in nonsignificant 1-year IOP change in OAG patients with uncontrolled or marginally controlled glaucoma and/or with severe VF loss.

Truncation of In Situ Baerveldt Glaucoma Drainage Device for Treatment of Late Persistent Postoperative Hypotony.

In situ truncation of Baerveldt drainage device with permanent, releasable tube occlusion offers a safe and effective intervention for eyes with late hypotony, and also allows for maintenance of IOP control long term.

Using Deep Learning to Automate Goldmann Applanation Tonometry Readings.

Preliminary measurements using deep learning to automate GAT demonstrate results comparable with those of standard GAT.

Smaller-incision Revision of Trabeculectomy With Mitomycin: Long-term Outcomes and Complications.

Smaller-incision trabeculectomy revision with MMC resulted in substantial, sustained IOP reduction in most eyes with poorly functioning filtering blebs, with few serious complications and rapid recovery of baseline visual acuity in most eyes.

Punctal Stenosis Associated with Topical Netarsudil Use.

Netarsudil use can lead to the development of reversible punctal stenosis.

Peripapillary and Macular Microcirculation in Glaucoma Patients of African and European Descent Using Optical Coherence Tomography Angiography.

No significant differences were found in peripapillary and macular microcirculation detected by OCTA between AD and ED glaucomatous eyes. Peripapillary and macular microcirculation were significantly correlated with disease severity in AD and ED glaucomatous eyes.

The Association Between Intermittent Fasting and Glaucoma.

In the 2005-2008 NHANES population, intermittent fasting, defined as breakfast skipping, was not associated with decreased risk of glaucoma diagnosis overall.

Quantitative Analysis of Retinal Nerve Fiber Layer Thickness Using SPECTRALIS Glaucoma Module Premium Edition and SPECTRALIS Standard Glaucoma Module.

Despite excellent correlation, global RNFL thickness and the RNFL thickness of most sectors differed significantly between GMPE and the SGM, sometimes markedly.

Combined Ahmed Glaucoma Valve Placement, Intravitreal Fluocinolone Acetonide Implantation and Cataract Extraction for Chronic Uveitis.

Combined AGV, intravitreal fluocinolone acetonide implant, and cataract extraction is effective in controlling IOP and reducing the number of glaucoma medications at 12 months after treatment in patients with chronic uveitis.

Peripapillary Retinal Nerve Fiber Layer Vascular Microcirculation in Glaucoma Using Optical Coherence Tomography-Based Microangiography.

Peripapillary RNFL vascular microcirculation measured as blood flux index by OMAG showed significant differences among OAG, glaucoma suspect, and normal controls and was significantly correlated with functional and structural defects.

Refusal of Trabeculectomy for the Fellow Eye in Collaborative Initial Glaucoma Treatment Study (CIGTS) Participants.

Refusal of fellow eye surgery was not uncommonly encountered in the CIGTS. Those who refused fellow eye surgery had lower fellow eye IOP and were more likely to have had hypotony after study eye trabeculectomy.

The Effect of Phacoemulsification on Intraocular Pressure in Glaucoma Patients: A Report by the American Academy of Ophthalmology.

Phacoemulsification typically results in small, moderate, and marked reductions of IOP and medications for patients with POAG, PXG, and PACG, respectively, and using 1 to 2 medications before surgery.
