Special Issue Information

Dear Colleagues,

In the last few years, the diagnosis of glaucoma has been significantly modified by the clinical introduction of innovative devices. The use of new sophisticated statistical models pursues the early detection of progression at any stage of the disease. Very recently, the first steps toward the integration of structural and functional data have been accomplished. There is increased awareness of progression at any stage of the disease by integrating structural and functional data. There is increased awareness of the importance of limiting ocular surface damage induced by treatments in order to achieve adequate adherence and preserve the quality of life in glaucoma patients. New medications are now available, and neuroprotection is frequently used as a complementary treatment for intraocular pressure reduction. Finally, the recent clinical introduction of several devices for minimally invasive glaucoma surgery has strongly modified the frequency and time at which patients are allocated to surgery. Following these innovations and despite the availability of specific guidelines, decision-making processes for glaucoma patients have become more complex, also due to increased attention to socioeconomic burdens and cost effectiveness analyses.

In this Special Issue, we seek to outline new advances in the glaucoma field, focusing on strategies to improve the clinical management of our patients.

Objective: This study aimed to investigate the structural, vascular, and biochemical alterations in patients with pseudoexfoliation syndrome (PES) and pseudoexfoliative glaucoma (PXG) and to evaluate the associations between serum biomarkers, the retinal nerve fiber layer (RNFL), choroidal thickness (CT), and vessel density (VD) in these groups. Methods: All subjects underwent spectral-domain optical coherence tomography (SD-OCT) and OCT angiography (OCTA) to assess RNFL thickness, CT, and VD. Serum levels of inflammatory and oxidative stress biomarkers—including malondialdehyde (MDA), glutathione (GSH), interleukin-6 (IL-6), nitric oxide (NO), inducible NO synthase (iNOS), galectin-3, and SCUBE-1—were analyzed, and regression and ROC curve analyses were performed to evaluate predictive value and diagnostic performance. Results: A total of 80 patients were included and are listed as follows: 25 controls, 30 with PES, and 25 with PXG. There were no significant differences among groups in terms of age or gender. RNFL thickness, CT, and VD were significantly reduced in the PXG group compared to the PES and control groups (p < 0.001). PXG patients showed the most pronounced reductions in both peripapillary and macular CT, as well as superficial and deep VD. Serum iNOS, SCUBE-1, galectin-3, and MDA levels were significantly elevated in PXG, while GSH levels were lower (p < 0.001); NO levels showed no significant differences. In the PES and PXG groups, several ocular parameters correlated significantly with serum biomarkers, particularly iNOS, MDA, and GSH. Regression analysis in PXG patients identified iNOS and MDA as significant predictors of RNFL thickness and VD. ROC analysis demonstrated that MDA and GSH exhibited the highest diagnostic accuracy among the tested biomarkers for distinguishing PXG patients from controls. Conclusions: PXG is associated with significant structural, vascular, and biochemical alterations, including reduced RNFL thickness, choroidal thinning, and decreased VD. Altered serum levels of MDA and GSH were significantly associated with these ocular changes and demonstrated the highest diagnostic accuracy among the biomarkers evaluated. These findings support their potential utility as non-invasive biomarkers for distinguishing PXG from PES and healthy controls and for monitoring disease progression. Full article

Background/Objectives: Black and Afro-Latinx communities have a higher propensity for more-severe glaucoma at a younger age. This study aimed to use the Kahook Dual Blade (KDB) to treat all glaucoma subtypes and severity levels in this historically underserved community. Materials and Methods: This study involved a retrospective analysis of surgical case records, with follow-up through 20 months. The subjects were glaucoma patients at Hospital Elias Santana in Santo Domingo, Dominican Republic. Inclusion criteria were age >18 years and a minimum follow-up of 1 year after surgery. All glaucoma subtypes and disease severities were included, including previous glaucoma procedures. Sequential patients undergoing KDB goniotomy alone or in combination with phacoemulsification cataract surgery were assessed. IOP data and number of medications were collected at specific time points: baseline, postoperative day 1, postoperative week 1, and postoperative months 1, 3, 6, 12, 16, and 20. Surgical outcome was determined using IOP and number of medications. Success was defined as either a 20% or more reduction in IOP or a decrease in at least one topical therapy. Recorded postoperative complications were hyphema, ocular hypertension, and need for additional glaucoma surgery. Results: A total of 90 eyes from 90 patients were included. A total of 100% of the patient population was Black or Afro-Latinx. The most common glaucoma subtype was primary open-angle (76.7%). Most of the eyes had severe glaucoma (53.3%). The mean preoperative baseline IOP was 20.5 mmHg. The mean postoperative IOP from all time points ranged from 12.9 to 13.5 mmHg (all time points were significantly lower than baseline IOP, p < 0.0001). A mean reduction in IOP percent of at least 31.5% was seen at every time point. There was a mean reduction of two medications by postoperative month 20. Surgical success was achieved in 95.6% of patients at postoperative month 1 and remained high throughout the study period (95.4% at month 20). Conclusions: KDB goniotomy achieved successful IOP and medication reduction across all levels of glaucoma severity. Surgical success rates were maintained to 20 months. While MIGS has historically been used as an intervention in mild-to-moderate glaucoma, our study results show that the KDB can play a significant role in all stages of glaucoma, including severe. MIGS should be considered as a favorable intervention in all disease severities in Black and Afro-Latinx communities around the world. Full article
