Summary: The aim of this study was to compare the results of OCTA and OCT examinations in patients with NTG and HTG at the early stage of glaucoma. The study found that the only statistical difference between early NTG and HTG in terms of RNFL thickness was observed in the temporal sector, with thinner values in the NTG group. There were no statistical differences between early NTG and HTG in terms of OCTA results.

Summary: This study aimed to determine the relationship between optical coherence tomography angiography (OCTA) metrics and visual field (VF) progression in eyes with normal tension glaucoma (NTG). The findings showed that lower superotemporal cpVD measured from OCTA in the peripapillary region improves the prediction of VF deterioration in NTG.

Summary: This study found that disc hemorrhage (DH) is associated with glaucoma progression. However, it is unclear whether the association between DH and glaucoma progression differs between the superior and inferior hemiretinas. The results showed that the macular ganglion cell complex (GCC) thickness had a stronger relationship with DH in the inferior hemiretina, suggesting that more attention should be paid to DH in the inferior disc area as a sign of glaucoma progression.

Summary: This study aims to analyze the effects of dynamic corneal response parameters (DCRs) on visual field (VF) progression in normal-tension glaucoma (NTG) and hypertension glaucoma (HTG). The results show that the first applanation deflection area (A1Area) is an independent risk factor for VF progression in NTG, while DCRs in HTG are not related to VF progression.

Summary: In this study, highly myopic NTG patients showed retinal thickness asymmetries in cpRNFL, TML, and mGCL. The diagnostic capabilities for TML and mGCL thickness asymmetry were comparable to those of cpRNFL and mRNFL thickness, indicating that asymmetry analysis of retinal thickness can be useful for early detection of NTG in highly myopic patients.

Summary: In patients with moderate-stage primary open-angle glaucoma, differences in intereye visual field defect (VFD) asymmetry were associated with varying rates of progression, with unilateral VFD eyes showing the fastest progression. Greater intereye MD asymmetry index and intereye hemifield visual-sensitivity asymmetry index were significant risk factors for glaucoma progression.

Summary: Glaucoma is a leading cause of irreversible blindness worldwide, characterized by optic nerve damage and visual field defects. While elevated intraocular pressure (IOP) is a significant risk factor, normal tension glaucoma (NTG) can occur within the normal range of IOP. Genetic mutations in optineurin (OPTN), TANK binding kinase 1 (TBK1), and myocilin (MYOC) have been identified as the primary causes of NTG. In this review, we examine pedigree studies and clinical features of NTG associated with these mutations.

Summary: NTG patients showed higher DCR values compared to controls, with some DCRs being negatively correlated with CCT and IOP, while others were positively correlated with these factors. The cornea was more deformable in NTG compared to HTG or controls, indicating a potential biomechanical mechanism underlying glaucomatous optic neuropathy in NTG patients.

Summary: The aim of this study was to compare the values of vessel density (VD) and perfusion parameters in the ophthalmic artery (OA) and central retinal artery (CRA) between hypertensive glaucoma (HTG) and normotensive glaucoma (NTG) patients. The results showed no differences in visual field (VF), VD, PSV-OA, and EDV-CRA between the two groups. However, statistically significant differences were observed in PSV of CRA, EDV of OA, and resistance index (RI) of both CRA and OA.

Summary: Growing evidence suggests that intracranial pressure (ICP) is important in the pathophysiology of glaucoma, especially in normal-tension glaucoma (NTG) patients. This study aims to assess the relationship between ICP and visual field (VF) zones in NTG patients. The results showed that higher translaminar pressure difference (TPD) was associated with lower mean deviation (MD) and higher pattern standard deviation (PSD). ICP was significantly associated with the lowest averaged pattern deviation (PD) scores in the nasal VF zone.

Summary: The study compares the patterns of visual field defects in normal-tension glaucoma (NTG) and high-tension glaucoma (HTG) with different severities. Results demonstrate that NTG exhibits significant asymmetry between the superior and inferior hemifields, while HTG shows more diffuse defects.

Summary: This study examined the agreement between clinical judgment and GPAII in evaluating visual field progression in glaucoma patients. Glaucoma experts showed better ability than general ophthalmologists in detecting progression, but the agreement between clinical judgment and GPAII ranged from fair to moderate.

Summary: Normal tension glaucoma (NTG) is a subtype of primary open-angle glaucoma (POAG) in which the intraocular pressure (IOP) values are within the normal range without treatment. The exact cause of NTG is not fully understood and multiple factors are believed to contribute to its development. Lowering IOP is the standard treatment for NTG, but it may not be enough in all cases, suggesting the involvement of other factors. Various therapeutic approaches targeting different risk factors have been proposed, but there is no standardized or proven alternative treatment for NTG. This review aims to highlight the strategies reported in the literature and the challenges in finding appropriate and effective treatments for NTG.

Summary: The purpose of this study was to identify risk factors for progression in treated normal-tension glaucoma (NTG) in highly myopic and non-highly myopic eyes. The results showed that the highly myopic group had a larger optic disc tilt ratio and thinner inferior macular thickness compared to the non-highly myopic group. Furthermore, basal pattern standard deviation and post treatment IOP were identified as risk factors for visual field progression in normal tension glaucoma patients.

Summary: The study showed that in otherwise healthy Japanese normal-tension glaucoma patients who received no treatment, the probability of disc haemorrhage occurrence was 31% at 5 years. Risk factors included lower myopic refraction, higher intraocular pressure during follow-up, and presence of disc haemorrhage at baseline.

Summary: This study aimed to investigate the changes in central visual field after fornix-based trabeculectomy with mitomycin C in Japanese normal-tension glaucoma patients. The results showed a significant positive change in 10-2 visual field after surgery, indicating that central vision can be maintained for NTG patients even with low preoperative IOP.

Summary: In Japanese patients with primary open-angle glaucoma (POAG) and intraocular pressure (IOP) of at most 15 mmHg undergoing prostaglandin F-2 alpha (FP) receptor agonist monotherapy, the addition of ripasudil hydrochloride hydrate led to significant IOP reduction at 1 and 3 months. Ripasudil could enhance the efficacy of FP monotherapy.

Summary: This study investigated the changes in corneal endothelial cell density (CECD) after initial Ex-PRESS surgery in Japanese patients with open-angle glaucoma (OAG) over a 36-month period. The results suggest that CECD after surgery may not pose clinical problems, but a low preoperative CECD is a significant risk factor for CECD loss. In addition, intraocular pressure (IOP) significantly decreased after surgery. Longer-term follow-up and regular CECD measurements are necessary for postoperative management, particularly in patients with low CECD.

Summary: In this study, switching from FP agonist to EP2 agonist showed significant improvement in deepening of the upper eyelid sulcus and eyelid/peri-eyelid skin pigmentation in patients with prostaglandin-associated periorbitopathy. The treatment with EP2 agonist increased patient satisfaction and did not affect intraocular pressure or visual acuity. The improvement in pigmentation was more easily achieved in nonmyopic eyes.

Summary: This study aimed to identify factors associated with disc/retina deterioration preceding the deterioration of the visual field in patients with OAG. The results showed that disc hemorrhage was significantly associated with disc/retina deterioration preceding visual field deterioration, while age was significantly associated with visual field deterioration preceding disc/retina deterioration.

Summary: The purpose of this study was to investigate the postoperative intraocular pressure (IOP) control and identify the factors associated with failure of initial Ex-PRESS surgery in patients with open-angle glaucoma for 3 years. The study found that Ex-PRESS surgery was effective in reducing IOP, but the intervention of bleb needling after 6 months was identified as a main risk factor for achieving lower IOP.
