Rothia Mucilaginosa Endophthalmitis Associated With iStent Inject Implantation
Postoperative endophthalmitis caused by Rothia mucilaginosa, a gram-positive, coagulase-negative Micrococcaceae of the oropharyngeal flora, is rare and all previously reported intraocular implant-related cases have resulted in evisceration. R. mucilaginosa endophthalmitis has also not been described with any glaucoma implant device. Here, the authors report a case of subacute R. mucilaginosa endophthalmitis after phacoemulsification with implantation of an intraocular lens and the iStent inject (Glaukos). The infection was managed with intravitreal antibiotic injections, pars plana vitrectomy, and intraocular lens and iSte...

Surgical Advancement of Tenon’s Layer During Trabeculectomy Improves Bleb Morphology
Trabeculectomy surgery remains the gold standard incisional glaucoma surgical procedure in many practices, particularly for patients requiring intraocular pressure (IOP) in the low teens or below. However, trabeculectomy surgery is associated with complications including leakage, over filtration, or fibrosis of the surgical bleb. Morphology of the surgical bleb is an important predictor of surgical success defined as long-term IOP reduction with minimal to no complications. There have been many, often subtle, variations in the surgical technique in hopes of improving long-term IOP reduction. However, fewer changes have bee...

Outcomes of Baerveldt Glaucoma Drainage Devices in Pediatric Eyes
Précis:
In children, Baerveldt implants showed 84% success at 1 year, but decreased to 32% at 8 years. Age, race, and glaucoma type were not risk factors for failure. Concurrent intraocular surgery was associated with complications.
Purpose:
Evaluate success and risk factors for failure and complications of Baerveldt glaucoma implants in children.
Methods:
Retrospective case series of children who underwent Baerveldt implant placement (2012-2019 by single surgeon) with ≥1 year follow-up. Ocular examination and surgical details were collected. Failure defined as intraocular pressure (IOP) 21 mm Hg f...

Three-Year Outcomes of Pars Plana Ahmed and Baerveldt Glaucoma Implantations for Neovascular Glaucoma in Japanese Eyes
This study examined 41 eyes of 39 patients who underwent tube shunt implantation through the pars plana with the Baerveldt glaucoma implant (BGI group, 26 eyes) or Ahmed glaucoma valve (AGV group, 15 eyes) for NVG and who were followed up for over 3 years at Osaka Medical College between January 2009 and April 2016. Outcome measures were intraocular pressure (IOP, mm Hg) at presurgery and at 6 months and 1, 2, and 3 years postoperative. Postoperative failure was defined as an IOP of>21 mm Hg or (Source: Journal of Glaucoma)

Intraocular Pressure Control Following Phacoemulsification in Eyes With Pre-existing Aurolab Aqueous Drainage Implant
Purpose:
The aim was to investigate intraocular pressure (IOP) control after phacoemulsification in adult glaucomatous eyes with a functioning nonvalved Aurolab Aqueous Drainage Implant (AADI) compared with eyes that did not have cataract extraction post-AADI.
Methods:
In this retrospective study, we reviewed records of 47 patients (47 eyes) who had a clear corneal phacoemulsification after AADI placement with a minimum of 2 years of follow up. The control group included 89 patients (89 eyes) who had a functional AADI at 1 year, minimum of 3 years of follow up post-AADI implantation, and no cataract extraction. ...

Gonioscopy-Assisted Transluminal Trabeculotomy for Glaucoma: 1-Year Outcomes and Success Predictors
Précis:
Our results suggest gonioscopy-assisted transluminal trabeculotomy (GATT) as an effective and safe option for the surgical management of open-angle glaucoma (OAG). Older age was the only risk factor for failure in our analysis.
Purpose:
To report 12-month clinical outcomes, safety profile and success predictors of GATT in patients with OAG.
Patients and Methods:
A retrospective study of patients (18 y old and above) with medically uncontrolled OAG who underwent GATT as a solo procedure or combined with phacoemulsification (PHACO-GATT) between January 2018 and January 2020. Success at 12 months ...

Readability of Online Patient Education Materials for Glaucoma
This study aimed to assess the readability of online glaucoma patient education materials.
Methods:
Glaucoma was entered into the Google search engine, and the first 30 search results were assessed for readability using seven validated readability instruments. Scientific articles, forums, and dictionary entries were excluded. Single sample t tests were used to assess whether online glaucoma materials were written above the recommended seventh grade level.
Results:
Overall, glaucoma materials were written at a mean grade level of 10.33 (SD: 2.02). Across 6 grade level readability instruments, these patient edu...

Prediction of Central Visual Field Severity in Glaucoma
We examined 64 eyes of 56 glaucoma patients with CVFDs on 24-2 VF with a mean deviation better than −7 dB and completed 24-2 and 10-2 VF testing within 6 months. On the basis of 10-2 VFs’ pattern defects, eyes were grouped into 3: an arcuate parafoveal scotoma, severe defect; partial arcuate, moderate defect; and minimal defect. VF parameters at abnormal points (P (Source: Journal of Glaucoma)

Association of Metabolic Syndrome With Glaucoma and Ocular Hypertension in a Midwest United States Population
Conclusion:
In Olmsted County, though metabolic syndrome was associated with ocular hypertension and higher intraocular pressure in patients with glaucoma, the results were likely related to a thicker central corneal in this patient population. (Source: Journal of Glaucoma)

Intraocular Pressure and Medication Burden With Cataract Surgery Alone, or Cataract Surgery Combined With Trabecular Bypass or Goniotomy
Conclusion:
Trabecular micro-bypass and goniotomy when added to cataract surgery resulted in a large decrease in IOP spikes, a modest effect on IOP, and a minimal effect on medication burden when compared with cataract surgery alone in glaucoma patients. (Source: Journal of Glaucoma)

Circumpapillary retinal nerve fiber layer (RNFL) thickness change induced by optical coherence tomography (OCT) scan circle location displacement was not completely compensated despite the use of Guided Progression Analysis (GPA), especially when the “R1” registration method was applied.
Purpose:
The purpose of this study was to evaluate the effect of inconsistent OCT scan location on glaucoma progression detection using GPA.
Methods:
Eighty-four glaucomatous eyes with at least 4 serial OCT tests were included. To evaluate the ability of OCT GPA to adjust the OCT scan location, an analysis wa...
