Anterior Chamber Angle Changes in Primary Angle-closure Glaucoma Following Phacoemulsification Versus Phacotrabeculectomy: A Prospective Randomized Clinical Trial
Précis:
We used anterior segment optical coherence tomography to investigate anterior chamber angle in primary angle-closure glaucoma (PACG) eyes following phacoemulsification and phacotrabeculectomy. Angle widening was significantly greater after phacoemulsification up to 6 months after the surgery.
Purpose:
To compare anterior chamber angle following 2 common surgeries for PACG.
Methods:
One hundred ten glaucoma patients were evaluated in this single center, prospective, randomized clinical trial. Those with concomitant PACG and senile cataract and without a history of ocular surgery, trauma, or chroni...

The Role of Artificial Intelligence in the Diagnosis and Management of Glaucoma
Glaucomatous optic neuropathy is the leading cause of irreversible blindness worldwide. Diagnosis and monitoring of disease involves integrating information from the clinical examination with subjective data from visual field testing and objective biometric data that includes pachymetry, corneal hysteresis, and optic nerve and retinal imaging. This intricate process is further complicated by the lack of clear definitions for the presence and progression of glaucomatous optic neuropathy, which makes it vulnerable to clinician interpretation error. Artificial intelligence (AI) and AI-enabled workflows have been proposed as a...

A Case of Secondary Pigment Dispersion Following Laser to Cosmetically Lighten the Irises
We report a rare case of bilateral secondary pigment dispersion following laser burns to the irises for cosmetic purposes. This case demonstrates a case of secondary pigment dispersion not previously reported in the literature to the best of our knowledge. (Source: Journal of Glaucoma)

Infective Necrotizing Scleritis After XEN Gel Stent With Mitomycin-C
Conclusions:
To our knowledge, this is the first reported case of necrotizing scleritis following XEN Gel Stent insertion. It is a reminder that infection should always be the primary differential diagnosis in patients with surgical-induced necrotizing scleritis. (Source: Journal of Glaucoma)

Corneal Endothelial Changes in Patients With Primary Congenital Glaucoma
Conclusions:
Prolonged exposure to elevated intraocular pressure during prenatal and/or early postnatal life results in structural changes in immature infant corneas. Specular microscopic parameters differed significantly between healthy controls and patients with PCG. The type of surgery had no effect on these parameters. Among patients with PCG, those with Haab striae had isolated corneal endothelial cell loss without morphologic changes within the endothelium. (Source: Journal of Glaucoma)

Risk Factors for Corneal Striae in Eyes After Glaucoma Surgery
Précis:
Eyes with corneal striae had steeper cornea, induced astigmatism, and higher corneal hysteresis (CH), which implies a relationship between striae, corneal shape, and the cornea’s resistance to deformation at low intraocular pressures (IOPs).
Background:
Anterior corneal striae (ACS) are associated with low IOP. However, the clinical significance of ACS is unclear. Here, we aim to evaluate differences in eyes with striae compared with eyes without striae.
Methods:
Adults with ACS (cases) and without ACS (controls) ≥8 weeks after glaucoma surgery with an IOP ≤10 mm Hg were enrolled. Optic...

Bilateral Nonpenetrating Deep Sclerectomy: Difference in Outcomes Between First- and Second-Operated Eyes at 24 Months
Background/Aim:
The aim of this study was to assess the difference in outcome between the first-operated and the second-operated eyes after nonpenetrating deep sclerectomy (DS), and to identify potential success predictors for the second eye.
Methods:
This single-surgeon, retrospective study analyzed the outcomes of all bilateral nonsimultaneous DS with at least 24 months of follow-up. Its main outcome measure was surgical success, defined as unmedicated intraocular pressure (IOP) ≤15 mm Hg associated with a relative reduction ≥20%.
Results:
In all, 104 eyes of 52 patients who underwent bilateral ...

Effect of Postoperative Trimming of the Tube Portion of Ahmed Glaucoma Valve on Corneal Endothelial Cell Loss
Précis:
We reduced the tube length through a small limbal incision in eyes that underwent Ahmed glaucoma valve (AGV) implantation and found that the rate of corneal endothelial cell (CEC) density was markedly reduced from −12.2% per year to −3.5% per year after this simple procedure.
Purpose:
The aim was to evaluate the effect of postoperative tube tip trimming (TT) after AGV implantation on CEC loss.
Methods:
In this retrospective cohort study, a total of 75 eyes from 67 patients (41 eyes in the AGV implantation only group (AGVG: mean follow-up, 42.2±13.8 mo) and 34 eyes in the TT after AGV impla...

Efficacy of Selective Laser Trabeculoplasty on Circadian Intraocular Pressure Following Trabeculectomy in Advanced Primary Open-angle Glaucoma
Conclusion:
SLT is effective and safe in lowering mdIOP to target IOP in about 50% of eyes after prior incisional glaucoma surgery. (Source: Journal of Glaucoma)

Digital Ocular Compressions Reduce Intraocular Pressure in Eyes With Tube Shunts
Conclusions:
DOC is an effective method for transiently reducing IOP in eyes with long-established, patent tube shunts for about an hour. To maintain this decrease in pressure, compressions will have to be performed on a scheduled basis. (Source: Journal of Glaucoma)

Anterior Segment OCT in Primary Angle Closure Disease Compared With Normal Subjects With Similar Shallow Anterior Chamber
Conclusions:
In PACD patients compared with normal subjects with similar anterior chamber shallowing, OCT findings measured at the iris root 250 μm from the scleral spur, especially in the oblique and vertical axes, including angle recess area and trabecular iris space area, may match gonioscopic findings more closely and provide further insight into mechanisms of PACD.

Prevalence of Open-angle Glaucoma in the Faroese Population
Conclusions:
The calculated prevalence of OAG in the Faroe Islands was 1.07%. The absence of MYOC, OPTN, or TBK1 disease-causing variants in Faroese primary OAG patients suggests that a different, potentially unique set of genes may be contributing to the pathogenesis of glaucoma in this population.

Attitudes and Perceptions Toward the Use of Medical Marijuana by Glaucoma Specialists
Conclusions:
Over 25% of the glaucoma specialists responded that MMJ had a role in the treatment of glaucoma, despite the recommendation of the professional society. This group was least likely to have received education on the topic. Given the expanding legality and curiosity of patients with regards to marijuana in the United States, it is important for ophthalmologists to have a greater understanding of the implications of marijuana in glaucoma.
