Abstract
PURPOSE To evaluate the factors affecting corneal deformation amplitude (DA) measured using Corvis ST in eyes with open-angle glaucoma. METHODS This prospective, longitudinal study included 48 eyes with open-angle glaucoma who required additional intraocular pressure (IOP)-lowering drops. All eyes underwent a complete eye examination at baseline, including a Corvis ST, which was repeated 4-8 weeks after the change in therapy. Factors affecting the corneal biomechanics, namely the DA, were determined using mixed effect models. RESULTS The mean age of the cohort was 65.0 ± 7.9 years. The mean IOP reduced from 23.4 ± 5.4 mmHg to 17.9 ± 5 mmHg after the change in glaucoma treatment ( P < 0.001). The DA increased from 0.89 ± 0.16 mm to 1.00 ± 0.13 mm after IOP reduction ( P < 0.001). On mixed effect model analysis, IOP (-0.02 ± 0.001, P < 0.001) and corneal pachymetry (-0.0003 ± 0.0001, P = 0.02) affected the change in the DA. CONCLUSION IOP and corneal pachymetry affect the DA and must be accounted for when using Corvis ST to evaluate corneal biomechanics in glaucoma.

Targeting lysyl-oxidase (LOX) may facilitate intramural periarterial drainage for the treatment of Alzheimer's disease. CEREBRAL CIRCULATION - COGNITION AND BEHAVIOR 2023; 5:100171.

Abstract
Alzheimer's disease is the commonest form of dementia. It is likely that a lack of clearance of amyloid beta (Aβ) results in its accumulation in the parenchyma as Aβ oligomers and insoluble plaques, and within the walls of blood vessels as cerebral amyloid angiopathy (CAA). The drainage of Aβ along the basement membranes of blood vessels as intramural periarterial drainage (IPAD), could be improved if the driving force behind IPAD could be augmented, therefore reducing Aβ accumulation. There are alterations in the composition of the vascular basement membrane in Alzheimer's disease. Lysyl oxidase (LOX) is an enzyme involved in the remodelling of the extracellular matrix and its expression and function is altered in various disease states. The expression of LOX is increased in Alzheimer's disease, but it is unclear whether this is a contributory factor in the impairment of IPAD in Alzheimer's disease. The pharmacological inhibition of LOX may be a strategy to improve IPAD and reduce the accumulation of Aβ in the parenchyma and within the walls of blood vessels.

Abstract
Background We report the real-world distribution of glaucoma types and glaucoma surgeries in each age or sex group in our department. Methods The department database of Matsue Red Cross Hospital, a tertiary care hospital, for eyes surgically treated to manage glaucoma between April 2014 and March 2018 was searched. Patient age, sex, disease type, and surgical procedure were collected from the database. The age was stratified by ≤64 years (young), 65–74 years (pre-old), 75–89 years (old), and ≥90 years (oldest-old or super-old). Results In the database, 2036 consecutive surgeries (70.3 ± 14.4 years; 1015 males) were identified. Among all subjects, primary open-angle glaucoma (POAG) (42.7%) was the most frequent identifiable glaucoma type followed by primary angle-closure disease (PACD) (18.8%) and exfoliation glaucoma (17.9%). The glaucoma types differed significantly among the age groups (P < 0.0001); POAG was the most frequent type of glaucoma in young and pre-old groups, while PACD and exfoliation glaucoma were the most frequent glaucoma types in the oldest-old group. Among all subjects, trabeculotomy or other goniotomy/gonio-bypass surgery (41.7%) was the most frequent glaucoma surgery followed by long-tube shunt (22.1%) and trabeculectomy (16.2%). The glaucoma surgeries performed differed significantly among the age groups (P < 0.0001). The frequency of trabeculectomy was the highest in the young group (27.8%), trabeculotomy was the highest in the pre-old (42.6%) and old (46.6%) groups, and long tube shunt (41.3%) and cataract extraction + goniosynechialysis (32.6%) were the highest in the oldest-old group. The glaucoma type (P < 0.0001) and surgeries performed (P < 0.0001) differed significantly between sex groups; the rates of PACD and cataract extraction + goniosynechialysis were remarkably higher in female than male group. Conclusion The types of glaucoma and required glaucoma surgeries differ among the different age groups and sexes. Primary angle-closure disease and exfoliation glaucoma are the major glaucoma types in the old and oldest-old age groups.

Abstract
Pseudoexfoliation (PXF) syndrome is an important public health concern requiring individual population level analysis. Disease prevalence differs by geographic location and ethnicity, and has environmental, demographic, genetic, and molecular risk factors have been demonstrated. Epidemiological factors that have been associated with PXF include age, sex, environmental factors, and diet. Genetic and molecular components have also been identified that are associated with PXF. Underserved populations are often understudied within scientific research, including research about eye disease such as PXF, contributing to the persistence of health disparities within these populations. In each population, PXF needs may be different, and by having research that identifies individual population needs about PXF, the resources in that population can be more efficiently utilized. Otherwise, PXF intervention and care management based only on the broadest level of understanding may continue to exacerbate health disparities in populations disproportionally burdened by PXF.

Abstract
BACKGROUND Single nucleotide polymorphisms (SNPs) in the gene encoding LOXL1 are risk factors for exfoliation syndrome and exfoliation glaucoma. This meta-analysis comprehensively investigated the association between LOXL1 gene polymorphisms (rs1048661, rs3825942, and rs2165241) and the risk of exfoliation syndrome/exfoliation glaucoma (XFS)/(XFG). METHODS All eligible case-control studies, published before August 17, 2020, were searched on Medline (Ovid), PubMed, CNKI, EMBASE, and Wanfang databases. RESULTS In total, 5022 cases and 8962 controls were included in this meta-analysis. Significant associations between LOXL1 gene polymorphisms and XFS/XFG risk was observed in the disease types-based subgroups. In addition, in the subgroup analysis of ethnicity, positive associations between LOXL1 gene polymorphisms (rs1048661, rs3825942, and rs2165241) and XFS/XFG risk were found in Caucasians. Furthermore, rs1048661 and rs3825942 polymorphisms were related to XFS/ XFG risk in Asians; however, no significant association was observed between the LOXL1 gene rs2165241 polymorphism and XFS/XFG risk in Asians. In addition, rs1048661 and rs3825942 correlated with XFS/XFG susceptibility in Africans. CONCLUSIONS Our results implicate LOXL1 gene polymorphisms as XFS/XFG risk factors, especially in Caucasians.

Abstract
Purpose To compare the corneal biomechanical parameters between pseudoexfoliation glaucoma (PXG), primary open-angle glaucoma (POAG) and healthy controls using Corvis ST. Methods A prospective, cross-sectional study was conducted which included 132 treatment-naïve eyes which underwent Corvis ST. The study cohort comprised of 44 eyes with PXG, 42 eyes with POAG and 46 healthy controls. Corneal biomechanical parameters, which included corneal velocities, length of corneal applanated surface, deformation amplitude (DA), peak distance and radius of curvature, were compared between the groups using analysis of variance models. Results The 3 groups were demographically similar. The mean IOP was 15.7 ±3 mmHg in the control group, 21.3 ±5 mmHg in the POAG group and 25.8 ±7 mmHg in the PXG group (p<0.0001). Corneal pachymetry was similar across the 3 groups. Mean DA was significantly lower (p<0.0001) in the PXG group (0.86 ±0.18 mm) compared to the POAG group (0.97 ±0.14mm) and the control group (1.10 ±0.15mm). Corneal velocities were also found to be statistically significantly different between the groups. However, after adjusting for IOP, there was no difference in any of the biomechanical parameters between the 3 groups. Conclusion Corneal biomechanical parameters measured on Corvis ST are not different between eyes with PXG, POAG and healthy controls after adjusting for IOP.

Abstract
Purpose To compare the corneal biomechanical parameters among pseudoexfoliation syndrome (PXF), pseudoexfoliation glaucoma (PXG), and healthy controls using Corvis Scheimpflug Technology (ST). Methods A prospective, cross-sectional study of 141 treatment-naïve eyes that underwent Corvis ST was conducted. These included 42 eyes with PXF, 17 eyes of PXF with ocular hypertension (PXF + OHT) defined as intraocular pressure (IOP)> 21 mmHg without disc/field changes, 37 eyes with PXG, and 45 healthy controls. Corneal biomechanical parameters, which included corneal velocities, length of corneal applanated surface, deformation amplitude (DA), peak distance, and radius of curvature, were compared among the groups using analysis of variance models. Results The four groups were demographically similar. The mean IOP was lower in the controls (15.6 ± 3 mmHg) and PXF group (16.0 ± 3 mmHg) compared to the other two groups (>24 mmHg). Corneal pachymetry was similar across the four groups. Mean DA was significantly lower (P < 0.0001) in the PXG group (0.91 ± 0.18 mm) and the PXF + OHT group (0.94 ± 0.13 mm) when compared to the PXF (1.10 ± 0.11 mm) and control groups (1.12 ± 0.14 mm). Corneal velocities were also found to be statistically significantly lower in PXG and PXF + OHT compared to the PXF and control groups. However, after adjusting for age and IOP, there was no difference in any of the biomechanical parameters among the four groups. Conclusion Corneal biomechanical parameters measured on Corvis ST are not different between healthy controls and eyes with PXF and PXG. Since PXG is a high-pressure glaucoma, corneal biomechanics may not play an important role in its diagnosis and pathogenesis.

Abstract
Epidemiological investigation of pseudoexfoliative syndrome (PEX) as a glaucoma predictor is necessary for antiglaucoma treatment planning. AIM To study the prevalence of PEX and pseudoexfoliative glaucoma (PXFG) among healthy people, naïve patients, and patients under observation as well as to evaluate the hypotensive efficacy of bimatoprost/timolol fixed combination (FCBT) over 4 months in PXFG. MATERIAL AND METHODS Epidemiological analysis, ophthalmological examination, statistical analysis. RESULTS The prevalence of PEX among healthy Novosibirsk and Novosibirsk region citizens is 19.9%. In ophthalmologically compromised population and first-time patients, the prevalence of PEX is 24%, of which PXFG constitutes 57.2%. Retrospectively, the prevalence of PXFG in PEX patients who were treated and followed up appeared to be as high as 60.8%. PXFG also accounts for 70% of all open-angle glaucoma cases in the Novosibirsk region, which is much higher than the corresponding rates in the European part of Russia. A 4-month FCBT therapy in 5 groups of PXFG patients (no treatment, monotherapy, another fixed combination, two drugs, three drugs) has yielded an evident hypotensive effect in most patients. The decrease in intraocular pressure was clinically significant in all groups. CONCLUSION There has been found a high prevalence of PEX and PXFG in the Novosibirsk region. FCBT has demonstrated high hypotensive efficacy at all stages of PXFG and was beneficial even in patients treated with other medications or fixed combinations and in refractory cases.

Abstract
Glaucoma is an umbrella term used to designate a heterogeneous group of ocular disorders characterised by progressive excavation of the optic disc, optic atrophy and gradual loss of the visual field caused by the slow death of retinal ganglion cells and their axons. Glaucoma can potentially lead to blindness if left untreated. It usually starts from the periphery and progresses gradually toward the centre of the visual field. Vision loss caused by glaucoma is irreversible and causes a heavy burden on affected families and society, therefore the importance of early diagnosis and prevention should be emphasised. Genetic factors appear to play a role in glaucoma pathogenesis; it has been shown that individuals with a positive family history are at a greater risk because they are more likely predisposed be affected. Notable advances have been recorded in the past decade concerning the genetic and environmental factors likely to contribute or cause glaucoma with the discovery of multiple glaucoma-associated genes and genetic loci. Thorough investigations by a handful of studies on the function of long non-coding RNAs discovered that, although lacking protein-coding potential, lncRNAs can still participate in the regulation of gene expression at various levels, thus their possible implication in different disease aetiologies. In this review, we focus on the lncRNAs characteristics and its regulation, and summarise these results from separate, independent, glaucoma-related studies in addition to discussing possible pathways by which lncRNAs might contribute to glaucoma.

Abstract
AIM There were several studies that have researched the associations between lysyl oxidase-like 1 (LOXL1) gene polymorphism and the susceptibility to exfoliation syndrome (XFS)/exfoliation glaucoma (XFG), but results have been inconclusive. MATERIALS AND METHODS A meta-analysis was performed for deriving more exact estimation of the relationship. Twenty-five studies were selected for studying rs1048661 and rs3825942. Sixteen studies were selected for studying rs2165241. RESULTS Single nucleotide polymorphism (SNP) rs1048661 was found to be associated with XFS/XFG, but the risk allele in white populations was found to be G, as opposite to the T allele in Japanese, Chinese, and Korean populations. The SNP rs3825942 was significantly associated with XFS in this black South African population. However, the AA genotype of rs3825942 confers XFS risk in this population, as opposed to the GG genotype described in all other populations. SNP rs2165241 was found to be associated with XFS/XFG, but the risk allele in white populations was found to be T, as opposite to the "C" allele in Japanese and Korean populations. CONCLUSIONS Our meta-analysis indicates that rs1048661 ("G" alleles) had weak association with XFG/XFS; rs3825942 ("G" alleles) had strongly association with XFG/XFS; and rs2165241("T" alleles) had significant risk with XFG/XFS in some ethnicity.

Abstract
Worldwide, the prevalence of moderate to severe visual impairment and blindness is 285 millions, with 65% of visually impaired and 82% of all blind people being 50 years and older. Meta-analyses have shown that two out of three blind people are women, a gender discrepancy that holds true for both developed and developing countries. Cataract accounts for more than half of all blindness globally and gender inequity in access to cataract surgery is the major cause of the higher prevalence of blindness in women. In addition to gender differences in cataract surgical coverage, population-based studies on the prevalence of lens opacities indicate that women have a higher risk of developing cataract. Laboratory as well as epidemiologic studies suggest that estrogen may confer antioxidative protection against cataractogenesis, but the withdrawal effect of estrogen in menopause leads to increased risk of cataract in women. For the other major age-related eye diseases; glaucoma, age-related macular degeneration (AMD) and diabetic retinopathy, data are inconclusive. Due to anatomic factors, angle closure glaucoma is more common in women, whereas the dominating glaucoma type; primary open-angle glaucoma (POAG), is more prevalent in men. Diabetic retinopathy also has a male predominance and vascular/circulatory factors have been implied both in diabetic retinopathy and in POAG. For AMD, data on gender differences are conflicting although some studies indicate increased prevalence of drusen and neovascular AMD in women. To conclude, both biologic and socioeconomic factors must be considered when investigating causes of gender differences in the prevalence of age-related eye disease.

Lack of association of LOXL1 gene variants in Japanese patients with central retinal vein occlusion without clinically detectable pseudoexfoliation material deposits. Acta Ophthalmol 2015; 93:e214-7. [PMID: 25130441 DOI: 10.1111/aos.12534] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2014] [Accepted: 07/10/2014] [Indexed: 12/23/2022]
Abstract
PURPOSE A possible association has been reported between exfoliation syndrome (EX) and various ocular and systemic vascular disorders; however, it is unclear if there is an association between EX and central retinal vein occlusion (CRVO). Because latent deposits of exfoliation materials might not be recognized during slit-lamp examination, an ocular biopsy is required to establish a precise diagnosis. We evaluated a possible association between EX and CRVO using lysyl oxidase-like 1 (LOXL1) gene variants as alternative markers for EX. METHODS The allelic and genotypic frequencies of three LOXL1 variants (rs1048661, rs3825942, and rs2165241) were determined in 68 consecutive Japanese patients with CRVO [15 with exfoliation syndrome (EX+) and 53 without exfoliation syndrome (EX-)] and 90 control patients with cataract without EX (CT). RESULTS The frequencies of the rs1048661 and rs3825942 variants showed borderline difference between the CRVO and CT groups (p = 0.04085 and p = 0.06088, respectively, for allelic frequencies, and p = 0.06838 and p = 0.03482, respectively, for genotypic frequencies). Compared with the CT group, subgroup analysis showed that the CRVO EX+ group had significant differences in the allelic and genotypic frequencies of rs1048661 (p = 0.0006447 and p = 0.0001392, respectively) and had borderline differences in the allelic and genotypic frequencies of rs3825942 (p = 0.03403 and p = 0.07341, respectively), while the CRVO EX- group did not (p = 0.1324-0.6306). Subgroup analysis showed that the frequencies of rs2165241 did not differ between the CRVO and CT groups. CONCLUSIONS When the LOXL1 variants were used as disease markers for clinically undetectable EX, there was no association between CRVO and EX. The results suggested that the LOXL1 variants, which are well-established markers for EX, are not likely genetic markers for CRVO in Japanese subjects.

Abstract
AIM To study the associations between lysyl oxidase-like 1 (LOXL1) polymorphisms and primary open angle glaucoma (POAG) remain inconsistent. In this study, we have performed a meta-analysis to investigate the association of LOXL1 polymorphisms with POAG risk. METHODS Published literature from PubMed and other databases were retrieved. All studies evaluating the association between LOXL1 polymorphisms (rs2165241, rs1048661, rs3825942) and POAG risk were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using random- or fixed-effects model. RESULTS Twelve studies were identified as eligible articles, with thirteen (2098 cases and 16 473 controls), thirteen (1795 cases and 2916 controls) and sixteen population cohorts (2456 cases and 2846 controls) for the association of rs2165241, rs1048661 and rs3825942 with POAG risk respectively. Overall analyses showed no association between each LOXL1 polymorphism and POAG risk, and the negative associations were remained when the subjects were stratified as Caucasian and Asian. The heterozygote of rs2165241 was associated with reduced POAG risk in hospital-based populations (TC vs CC: OR, 0.79, 95%CI: 0.63-0.99), and rs1048661 was associated with increased POAG risk in hospital-based populations in a dominant model (TT vs CC+CT: OR, 1.23, 95%CI: 1.01-1.50); however, these associations were not found in population-based subjects. CONCLUSION This meta-analysis suggests that LOXL1 polymorphisms are not associated with POAG risk. Given the limited sample size, the associations of LOXL1 polymorphisms with POAG risk in hospital-based populations await further investigation.

Abstract
Several members of the lysyl oxidase family have recently emerged as important regulators of tumor progression. Among them, LOXL2 has been shown to be involved in tumor progression and metastasis of several tumor types, including breast carcinomas. Secreted LOXL2 participates in the remodeling of the extracellular matrix of the tumor microenvironment, in a similar fashion to prototypical lysyl oxidase. In addition, new intracellular functions of LOXL2 have been described, such as its involvement in the regulation of the epithelial-to-mesenchymal transition, epithelial cell polarity and differentiation mediated by transcriptional repression mechanisms. Importantly, intracellular (perinuclear) expression of LOXL2 is associated with poor prognosis and distant metastasis of specific tumor types, such as larynx squamous cell carcinoma and basal breast carcinomas. These recent findings open new avenues for the therapeutic utility of LOXL2.

Abstract
PURPOSE To determine the prevalence of pseudoexfoliation syndrome (PEX) in Lithuanian urban population and its association with ischaemic heart disease (IHD), arterial hypertension (AH) and diabetes mellitus (DM). METHODS In this population-based study, 1065 participants aged 45-72 years were randomly drawn from the population register of Kaunas, Lithuania. They were classified as having PEX if any pseudoexfoliation material was determined by a slit-lamp examination in at least one eye. The data were acquired from questionnaire; register of myocardial infarction, electrocardiogram, biochemical blood analyses and blood pressure measurement were used to determine IHD, AH, DM and smoking habits. Poststratification weights based on Kaunas population sex and age distribution were applied. RESULTS Pseudoexfoliation syndrome was estimated in 9% of a population. The AH rate was higher in PEX subjects than in non-PEX subjects (p=0.017) and the rates of IHD, DM and cholesterol levels did not differ statistically significantly. Chi-square linear-by-linear association test found higher AH rate in unilateral PEX subjects and even higher AH rate in bilateral PEX subjects than in non-PEX subjects (p=0.014). Pseudoexfoliation syndrome increased odds for AH by 1.8 times (p=0.021). Median of systolic blood pressure was higher in the PEX group than in non-PEX group (p=0.04). But all associations could not be confirmed after adjusting for age. Smoking duration increased age-adjusted odds for PEX. Pseudoexfoliation syndrome did not increase risk for IHD, AH or DM. CONCLUSIONS Pseudoexfoliation syndrome prevalence is high in Lithuania. No clear PEX association with IHD, AH and DM was proven after controlling for effect of age.
