Ergun SB, Kurt B. Complete Blood Cell Count-Derived Inflammation Biomarkers in Patients with Xanthelasma Palpebrarum. BEYOGLU EYE JOURNAL 2024; 9:33-37. [PMID: 38504961 PMCID: PMC10944854 DOI: 10.14744/bej.2024.48802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 01/25/2024] [Accepted: 01/31/2024] [Indexed: 03/21/2024]
Abstract
Objectives Xanthelasma palpebrarum (XP) is the most common type of cutaneous xanthoma, characterized by yellowish cutaneous plaques commonly located near the medial canthus of the eyelid. Although dyslipidemia significantly contributes to its development, inflammation is also believed to be another element in the pathogenesis, especially in normolipidemic patients. Recently, cell counts derived from complete blood counts have been identified as indicators of systemic inflammatory conditions and have also been under discussion concerning their relevance to ocular diseases. This study aimed to assess inflammation indices derived from complete blood cell counts (CBC) in XP patients with normal lipid levels. Methods Patients who had been referred to the oculoplasty department with the diagnosis of XP between January 2020 and January 2023 and age-matched control subjects were retrospectively reviewed. Patients who had abnormal lipid profiles and systemic diseases such as diabetes mellitus, hypertension, malignancy, cardiovascular diseases, systemic infections, and inflammatory diseases were not included in the study. CBC parameters were analyzed and compared between the groups. Results The study comprised 27 normolipidemic patients with XP and 27 age-matched healthy individuals as the control group. There were no statistically significant differences between the two groups in terms of age (p=0.143). The mean hemoglobin, neutrophil, monocyte, lymphocyte, platelet, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, systemic immune-inflammation index, and aggregate index of systemic inflammation values were higher in the patient group, but the differences were not statistically significant (p>0.05). The mean red cell distribution width and platelet-to-lymphocyte ratio appeared to be lower in the patient group compared to the control group; however, no significant differences were observed between the two groups (p=0.272, p=0.387, respectively). Conclusion This study might offer insights into the pathogenesis of XP, yet numerous questions remain unanswered, awaiting further investigation in future studies.

Abstract
Introduction Glaucoma is the most common optic neuropathy and the leading cause of irreversible blindness worldwide, which affects 3.54% of the population aged 40-80 years. Despite numerous published studies, some aspects of glaucoma pathogenesis, serum biomarkers, and their potential link with other diseases remain unclear. Recent articles have proposed that autoimmune, oxidative stress and inflammation may be involved in the pathogenesis of glaucoma. Methods We investigated the serum expression of 92 inflammatory and neurotrophic factors in glaucoma patients. The study group consisted of 26 glaucoma patients and 192 healthy subjects based on digital fundography. Results Patients with glaucoma had significantly lower serum expression of IL-2Rβ, TWEAK, CX3CL1, CD6, CD5, LAP TGF-beta1, LIF-R, TRAIL, NT-3, and CCL23 and significantly higher expression of IL-22Rα1. Conclusion Our results indicate that patients with glaucoma tend to have lower levels of neuroprotective proteins and higher levels of neuroinflammatory proteins, similar to those observed in psychiatric, neurodegenerative and autoimmune diseases, indicating a potential link between these conditions and glaucoma pathogenesis.

Abstract
Aim: To explore the association between two systemic inflammation markers, platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR), and glaucoma. Materials & methods: The authors searched PubMed, Embase and the Cochrane Library for eligible studies comparing PLR and LMR levels in glaucoma patients and healthy controls. Results: Analysis revealed that glaucoma patients exhibited significantly elevated PLR levels and reduced LMR compared with nonglaucoma controls. These findings were consistent across various glaucoma types, with the exception of secondary glaucoma, where the association with PLR was less significant. Conclusion: The authors found PLR and LMR to be potential valuable biomarkers for glaucoma identification and progression monitoring. These findings highlight the role of systemic inflammation in glaucoma pathogenesis.

Abstract
Primary glaucoma is a painful, progressive, and blinding disease reported in many canine breeds, characterized by intraocular pressure (IOP) elevation in the absence of antecedent intraocular disease. Clinical observations of dogs with primary glaucoma suggest that many affected eyes develop concurrent intraocular inflammation in addition to elevated IOP. In this work, we summarize the current knowledge that relates inflammation to primary glaucoma in dogs, reviewing studies focused on genetics, physiology, histopathology, bioanalysis of ocular fluids, therapeutics, and clinical outcomes of glaucomatous patients. Through disruption of the blood-aqueous and blood-retinal barriers, pigment dispersion, and biochemical changes to the aqueous humor and tear film, the pathogenesis of canine primary glaucoma appears to involve inflammatory changes to various extents and with various consequences from the front to the back of the eye. Among others, inflammation further impacts IOP by reducing aqueous humor outflow at the level of the iridocorneal angle and accelerates vision loss by promoting neuronal degeneration. As such, the vicious cycle of ocular inflammation and IOP elevation might warrant the use of anti-inflammatory medications as a core component of the treatment regime for dogs with primary glaucoma, either therapeutically (i.e., actively glaucomatous eye) or prophylactically in the yet unaffected contralateral eye.

The inflammatory potential of diet is associated with the risk of age-related eye diseases. Clin Nutr 2023; 42:2404-2413. [PMID: 37865012 DOI: 10.1016/j.clnu.2023.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 09/26/2023] [Accepted: 10/09/2023] [Indexed: 10/23/2023]
Abstract
BACKGROUND & AIMS Inflammation is involved in the pathogenesis of cataract, age-related macular degeneration (AMD), and possibly open-angle glaucoma (OAG). We assessed whether the inflammatory potential of diet (quantified using the dietary inflammatory index; DII) affects the incidence of these common blinding age-related eye diseases. Serum inflammation markers were investigated as possible mediators. METHODS Participants aged >45 years were selected from the prospective, population-based Rotterdam Study. From 1991 onwards, every 4-5 years, participants underwent extensive eye examinations. At baseline, blood samples and dietary data (using food frequency questionnaires) were collected. The DII was adapted based on the data available. Of the 7436 participants free of eye diseases at baseline, 4036 developed incident eye diseases during follow-up (cataract = 2895, early-intermediate AMD = 891, late AMD = 81, OAG = 169). RESULTS The adapted DII (aDII) ranged from -4.26 (i.e., anti-inflammatory) to 4.53 (i.e., pro-inflammatory). A higher aDII was significantly associated with increased inflammation. A higher neutrophil-lymphocyte ratio (NLR) was associated with an increased risk of cataract and AMD. Additionally, complement component 3c (C3c) and systemic immune-inflammation index (SII) were associated with increased risks of cataract and late AMD, respectively. Every point increase in the aDII was associated with a 9% increased risk of cataract (Odds ratio [95% confidence interval]: 1.09 [1.04-1.14]). The NLR and C3c partly mediated this association. We also identified associations of the aDII with risk of AMD (early-intermediate AMD, OR [95% CI]: 1.11 [1.03-1.19]; late AMD, OR [95% CI]: 1.24 [1.02-1.53]). The NLR partly mediated these associations. The aDII was not associated with OAG. CONCLUSIONS A pro-inflammatory diet was associated with increased risks of cataract and AMD. Particularly the NLR, a marker of subclinical inflammation, appears to be implicated. These findings are relevant for patients with AMD and substantiate the current recommendations to strive for a healthy lifestyle to prevent blindness.

Abstract
OBJECTIVE To investigate the pathogenesis of primary angle-closure disease (PACG) by measuring the anatomical structures of the anterior and posterior segments of the eye and inflammatory markers in the peripheral blood. METHODS This case-control study enrolled patients diagnosed with acute PACG (APACG) and chronic PACG (CPACG). It also enrolled control subjects without PACG. The anterior and posterior anatomical features were measured in all study participants. The levels of interleukin (IL)-6, tumour necrosis factor-α and the neutrophil-to-lymphocyte ratio (NLR) in the peripheral blood were measured. RESULTS This study analysed a total of 99 eyes: 34 eyes from 34 patients with APACG, 28 eyes from 28 patients with CPACG and 37 eyes from 37 control patients with senile cataract. The axis length, corneal diameter, anterior chamber depth and anterior chamber volume were significantly smaller in the APACG and CPACG groups compared with the controls. The level of IL-6 in the peripheral blood of patients with PACG was significantly lower than that of the controls. The NLR in the peripheral blood of patients with PACG was significantly greater than that of the controls. CONCLUSIONS Changes in the ocular anatomy and some inflammatory markers might be involved in the pathogenesis of PACG.

Song DJ, Fan B, Li GY. Blood cell traits and risk of glaucoma: A two-sample mendelian randomization study. Front Genet 2023; 14:1142773. [PMID: 37124610 PMCID: PMC10130872 DOI: 10.3389/fgene.2023.1142773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 04/03/2023] [Indexed: 05/02/2023] Open
Abstract
Importance: Glaucoma is the second leading cause of blindness in the world. The causal direction and magnitude of the association between blood cell traits and glaucoma is uncertain because of the susceptibility of observational studies to confounding and reverse causation. Objective: To explore whether there is a causal relationship of blood cell traits including white blood cell (WBC) count (WBCC) and its subtypes [basophil cell count (BASO), monocyte cell count (MONO), lymphocyte cell count (LYMPH), eosinophil cell count (EOS), neutrophil cell count (NEUT)], red blood cell (RBC) count (RBCC), red blood distribution width (RDW), platelet count (PLT), and plateletcrit (PCT) on glaucoma risk. Methods: A two-sample Mendelian randomization (MR) analysis was conducted. Genome-wide significant single nucleotide polymorphisms (SNPs) from published genome-wide association studies (GWAS) on human blood cell traits were utilized as exposure instruments and the dataset for outcome was from the GWAS summary data of glaucoma. In the univariable MR analysis, we examined the association between genetic evidence of blood cell traits and glaucoma. To further investigate the potential causal mechanisms underlying the observed association, we performed multivariable MR analysis with three models, taking into account the mediator effect of inflammation and oxidative stress. According to Bonferroni-corrected for the 10 exposures in 3 methods, the MR study yielded a statistically significant p-value of 0.0017. Results: Genetically BASO, PCT, LYMPH, and PLT were potentially positively associated with glaucoma in the European ancestry [BASO: Odds ratio (OR) = 1.00122, 95% confidence interval (CI), 1.00003-1.00242, p = 0.045; PCT: OR = 1.00078, 95% CI, 1.00012-1.00143, p = 0.019; LYMPH: OR = 1.00076, 95% CI, 1.00002-1.00151, p = 0.045; PLT: OR = 1.00065, 95% CI, 1.00006-1.00123, p = 0.030], There was insufficient evidence to support a causal association of MONO, NEUT, EOS, WBCC, RBCC and RDW (MONO: OR = 1.00050, p = 0.098; NEUT: OR = 1.00028, p = 0.524; EOS: OR = 1.00020, p = 0.562; WBCC: OR = 1.00008, p = 0.830; RBCC: OR = 0.99996, p = 0.920; RDW: OR = 0.99987, p = 0.734) with glaucoma. The multivariable MR with model 1, 2, and 3 demonstrated that BASO, PCT, LYMPH, and PLT were still potentially genetically associated with the risk of glaucoma. Conclusion: Our study reveals a genetic predisposition to higher LYMPH, BASO, PLT, and PCT are associated with a higher risk of glaucoma, whereas WBCC, MONO, EOS, NEUT, RBCC, and RDW are not associated with the occurrence of glaucoma. This finding also supports previous observational studies associating immune components with glaucoma, thus provide guidance on the predication and prevention for glaucoma.

Abstract
This retrospective study investigated circulating immune cell alteration in patients with myopic retinopathy. Blood test results and demographic and ocular information of 392 myopic patients and 129 emmetropia controls who attended Changsha Aier Eye Hospital from May 2017 to April 2022 were used in this study. Compared with emmetropia, the percentages of neutrophils and basophils and neutrophil/lymphocyte ratio were significantly higher in myopic patients, whereas the percentages of monocytes and lymphocytes and the counts of lymphocytes and eosinophils were significantly lower in myopic patients. After adjusting for age and hypertension/diabetes, the difference remained. Interestingly, the platelet counts were significantly lower in myopic patients after the adjustments. Further subgroup analysis using multivariable linear regression showed that higher levels of neutrophils, neutrophil/lymphocyte ratio, and platelet/lymphocyte ratio, lower levels of monocytes, eosinophils, lymphocytes, and platelets, were related to myopic peripheral retinal degeneration (mPRD) and posterior staphyloma (PS). A higher level of basophils was linked to myopic choroidal neovascularization (mCNV). Our results suggest that higher levels of circulating neutrophils and neutrophil/lymphocyte ratio, lower monocytes, eosinophils, lymphocytes, and platelets are related to mild myopic retinopathy. A higher level of circulating basophils is related to the severe form of myopic retinopathy, such as mCNV.

[PMID: 36451140 PMCID: PMC9714010 DOI: 10.1186/s12886-022-02688-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Accepted: 11/15/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Previous reports have suggested that inflammation levels play a crucial role in the pathogenesis of high myopia (HM). This study aimed to investigate the relationship between HM and systemic inflammation using the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). METHODS Overall, 100 age- and sex-matched participants were recruited for the study, including 50 participants each in the non-HM (NHM) and HM groups. Ocular examinations and blood tests were performed. The NLR and PLR values were calculated from complete blood counts. Receiver operating characteristic (ROC) curves and optimal cut-off values were used to determine the optimal values of the NLR and PLR to distinguish between the HM and NHM groups. RESULTS The values of NLR and PLR were significantly elevated in the HM group compared with those in the NHM group (P < 0.001 and P = 0.010, respectively). Axial length (AL) was significantly correlated with the NLR (r = 0.367, P < 0.001) and PLR (r = 0.262, P = 0.009). In the ROC analysis, the NLR value to distinguish between the HM and NHM groups was 0.728; the best cut-off value was 2.68, with 76% sensitivity and 62% specificity. The PLR value to distinguish between the HM and NHM groups was 0.650; the best cut-off value was 139.69, with 52% sensitivity and 76% specificity. CONCLUSION The findings of this study indicate that the development of HM may be associated with systemic inflammation measured using the NLR and PLR. TRIAL REGISTRATION The study was registered on December 28, 2021 ( http://www.chictr.org.cn ; ChiCTR2100054834).

The Diagnostic Value of Neutrophil to Lymphocyte Ratio as an Effective Biomarker for Eye Disorders: A Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2022; 2022:5744008. [PMID: 36281463 PMCID: PMC9587911 DOI: 10.1155/2022/5744008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 09/09/2022] [Accepted: 09/20/2022] [Indexed: 11/28/2022]
Abstract
The neutrophil to lymphocyte ratio (NLR) reflects a dynamic relationship between the innate (neutrophils) and adaptive (lymphocytes) cellular immune response. This systematic review and meta-analysis was conducted to critically evaluate the literature regarding the use of the NLR as a reliable means to detect several ocular disorders. Our study was registered with the PROSPERO (ID: CRD42022314850). Three databases, including PubMed, Embase, Scopus, and the Web of Science, were searched on September 9, 2022, with no restrictions on the article's language. Finally, 32 articles were recognized as eligible for our meta-analysis. We found that patients with eye diseases had significantly elevated levels of NLR in comparison to healthy controls (SMD =0.53, 95% CI =0.35-0.71, P < 0.001). In subgroup analysis, patients with keratoconus (SMD =0.69; 95% CI =0.33-1.05, P < 0.001), glaucoma (SMD =0.56, 95% CI =0.25-0.87, P < 0.001), pterygium (SMD =0.14; 95% CI =0.01-0.26, P < 0.001), and idiopathic epiretinal membrane (SMD =0.14; 95% CI =0.01-0.26, P < 0.001) had higher levels of NLR compared to healthy controls. However, NLR levels of patients with dry eye disease were similar to healthy controls (SMD =0.32, 95% CI = -0.49-1.13, P = 0.435). It can be said that NLR is a valuable marker of systemic inflammation, which is significantly increased in many eye disorders, suggesting that inflammation plays a key role in the pathophysiology of these diseases.

Abstract
Purpose To assess the predictive value of inflammatory blood biomarkers in rhegmatogenous retinal detachment (RRD) patients and its correlation with proliferative retinopathy (PVR) grade. Methods 82 RRD patients and 1 : 1 age- and gender-randomly matched cataract patients as the control group were included. The clinical features and laboratory parameters of all participants were collected and recorded, and the comprehensive index of inflammatory blood and its correlation with PVR were calculated. Results Monocytes and monocyte-to-high-density lipoprotein ratio (MHR) were significantly lower (P=0.005, P=0.044), while mean platelet volume (MPV), lymphocyte-to-monocyte ratio (LMR), and MPV-to-platelet ratio (MPR) were significantly higher in RRD patients as compared with the control group (P=0.013, P=0.019, P=0.037). LMR and MPR might be the predictors of RRD. The receiver operating characteristics analysis showed that the values of MPV, LMR, and MPR in RRD patients were 0.612, 0.606, and 0.594, respectively. PVR grade was not associated with inflammatory blood biomarkers. Conclusion The increase in MPV, LMR, and MPR were associated with increased odds of RRD. LMR and MPR may be useful as inexpensive and effortless biomarkers for assessing the occurrence of RRD.

Abstract
Purpose To compare retinal ganglion cell complex (GCC) parameters between rhegmatogenous retinal detachment (RRD) eyes and normal contralateral eyes after vitrectomy and to evaluate their correlation with inflammatory blood markers. Methods We investigated 25 eyes that underwent vitrectomy due to RRD. Venous blood samples were collected from all participants before 08:00 a.m. on the second day of admission after a 12-hour fast for blood counts. The differences of retinal structure between RRD and contralateral eyes were compared 1 week postoperatively. Results Focal loss volume (FLV) (2.009 ± 1.286)% was significantly increased compared with the contralateral eyes (p < 0.001). Monocyte-to-high-density lipoprotein was significantly positively correlated with GCC thickness parameters, and negatively correlated with FLV and global loss volume (GLV). Postoperative best-corrected visual acuity was negatively correlated with GLV (p = 0.039, R2 = 0.172). Conclusion Retinal ganglion cells (RGCs) loss might present early postoperatively in RRD eyes, and was associated with systemic inflammation. RGCs loss might affect postoperative vision.

Complete Blood Count-Derived Inflammation Indices and Retinal Vein Occlusion: A Case-Control Study. Ophthalmol Ther 2022; 11:1241-1249. [PMID: 35503164 PMCID: PMC9114275 DOI: 10.1007/s40123-022-00511-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 04/08/2022] [Indexed: 11/26/2022] Open
Abstract
Introduction This study evaluated complete blood count-derived inflammation indices in patients with retinal vein occlusion (RVO). Methods Participants in this case–control study were 54 patients with RVO and 54 age- and sex-matched control subjects. All participants underwent a thorough ophthalmic examination, as well as blood sample testing for complete blood count. Comparison of all parameters derived from complete blood count as well as calculation of specific indices was performed between patients with RVO and controls. Results Patients with RVO presented significantly higher white blood cell count (p = 0.033), neutrophil count (p = 0.003), neutrophil-to-lymphocyte ratio (NLR, p = 0.002), red cell distribution width (RDW, p = 0.009), mean platelet volume (MPV, p = 0.023), and systemic immune-inflammatory index (SII, p = 0.007) compared to controls. Receiver operator characteristic curve (ROC) analysis showed that NLR was superior to other inflammatory indices, having the greatest area under the curve. The optimal cutoff value for NLR to predict RVO was 2.29 with 46.2% sensitivity and 77.8% specificity. Conclusion Patients with RVO presented increased NLR, RDW, MPV, and SII, providing evidence that inflammation plays an important role in the pathogenesis of RVO. Complete blood cell count-derived indices can be easily calculated and may serve as an easy, simple, and cost-effective tool to evaluate the degree of systemic inflammation in patients with RVO, so as to potentially guide treatment.

Abstract
To explore the effect of phacoemulsification along with intraocular lens (IOL) implantation on the treatment of primary angle closure glaucoma (PACG), a total of 50 patients (54 eyes) with PCG who had undergone surgery were selected as the research objects, in which, there were 16 eyes
with the acute PACG in pre-clinical stage, 20 eyes with acute PACG during acute attack, and 18 eyes with chronic PACG, and all patients received phacoemulsification along with IOL implantation therapy. The patient’s best corrected visual acuity, anterior chamber (AC), anterior depth,
intraocular pressure (IOP), visual field, and fundus conditions were measured during the operation, after the operation, and during the follow-up period. The postoperative visual acuity of the patients with three types of PACG was greatly corrected, in which 30 eyes had corrected visual acuity
above 0.5, and there were statistically significant differences (SSDs) (P < 0.05); angle closure of 54 eyes had different degrees of improvement, the opening degree of the acute angle closure is better than that of the chronic angle closure, and there were SSDs (P < 0.05);
each of 54 eyes showed different degrees of deepening in the central AC, and there were SSDs (P < 0.05); postoperative IOP decreased greatly in all 54 eyes, and there were SSDs (P < 0.05). In conclusion, the IOL implantation based on phacoemulsification can effectively
treat the PACG, at the same time reduce IOP, promote angle opening, enhance vision field of the patients, and ultimately achieve the purpose of improving surgical success.

EPMA J 2021; 12:659-675. [PMID: 34745391 PMCID: PMC8561372 DOI: 10.1007/s13167-021-00260-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 10/17/2021] [Indexed: 12/18/2022]
Abstract
RELEVANCE Accumulating evidence suggests a dysfunction of the para-inflammation in the retinal ganglion cell layer and the optic nerve head in patients with glaucoma. Currently, circulating blood platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR) are regarded as novel indicators of systemic inflammation. Biomarkers allow early identification of patients with visual field (VF) loss progression and timely implementation of replacement therapies. OBJECTIVE This study aimed to investigate whether higher inflammatory indices (PLR, NLR, and LMR) were associated with VF loss progression in patients with primary angle-closure glaucoma (PACG) for the predictive diagnostics, targeted prevention, and personalization of medical services. METHODS This prospective cohort study followed up 277 patients with PACG for at least 24 months, with clinical examination and VF testing every 6 months. Inflammatory cell quantification, including platelets, neutrophils, lymphocytes, and monocytes, was measured using the Sysmex XN-A1 automated inflammatory cells quantification system. Three systemic inflammatory indices, PLR, NLR, and LMR, were determined on the basis of baseline neutrophil, lymphocyte, monocyte, and platelet counts in patients with PACG. The risk factors for PACG were analyzed using logistic regression, Cox proportional hazards regression, and the Kaplan-Meier curve. RESULTS Our results revealed that 111 (40.07%) patients showed VF loss progression. The PLR was significantly higher (P = 0.046) in the progression group than in the non-progression group. A higher PLR (OR 1.05, 95% CI 1.01-1.08, P = 0.004) was a risk factor for PACG progression. In multivariate analyses, PLR independently predicted VF loss progression (HR 1.01, 95% CI 1.00-1.01, P = 0.04). Kaplan-Meier curve analysis showed that higher PLR indicated significantly higher rates of VF loss progression (66.91% vs. 52.90%, P = 0.03). Comparable results were observed in the male and female subgroups. CONCLUSION Our findings revealed the significant association between a high PLR and a greater risk of VF loss progression in patients with PACG. PLR may be highly recommended as a novel predictive/diagnostic tool for the assessment of VF loss progression from the perspectives of predictive, preventive, and personalized medicine in vulnerable populations and for individual screening.

Abstract
Glaucoma is an insidious group of eye diseases causing degeneration of the optic nerve, progressive loss of vision, and irreversible blindness. The number of people affected by glaucoma is estimated at 80 million in 2021, with 3.5% prevalence in people aged 40-80. The main biomarker and risk factor for the onset and progression of glaucoma is the elevation of intraocular pressure. However, when glaucoma is diagnosed, the level of retinal ganglion cell death usually amounts to 30-40%; hence, the urgent need for its early diagnosis. Molecular biomarkers of glaucoma, from proteins to metabolites, may be helpful as indicators of pathogenic processes observed during the disease's onset. The discovery of human glaucoma biomarkers is hampered by major limitations, including whether medications are influencing the expression of molecules in bodily fluids, or whether tests to validate glaucoma biomarker candidates should include human subjects with different types and stages of the disease, as well as patients with other ocular and neurodegenerative diseases. Moreover, the proper selection of the biofluid or tissue, as well as the analytical platform, should be mandatory. In this review, we have summarized current knowledge concerning proteomics- and metabolomics-based glaucoma biomarkers, with specificity to human eye tissue and fluid, as well the analytical approach and the main results obtained. The complex data published to date, which include at least 458 different molecules altered in human glaucoma, merit a new, integrative approach allowing for future diagnostic tests based on the absolute quantification of local and/or systemic biomarkers of glaucoma.

Abstract
Background The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been used as indicators of inflammation, however, their roles in dry eye disease (DED) patients require advanced study. Materials and Methods A total of 104 DED cases and 97 healthy controls from January 2020 to May 2020 were enrolled in this study. The dry eye related clinical variables, including Schirmer I test, tear break-up time (TBUT), corneal fluorescein staining (CFS) and Ocular Surface Disease Index (OSDI), were detected in all the participants. Besides, the NLR and PLR pattern in DED cases were detected and their potential value as inflammatory predictors of DED were evaluated. In advanced analyses, the correlation between NLR and DED severity was examined. Results The NLR and PLR were 2.59 ± 1.25 and 117.48 ± 54.68 in the DED group, respectively, while they were 2.20 ± 1.24 and 115.48 ± 54.33 in the control group, respectively. The NLR was higher in the DED group (p = 0.027), however, PLR was not significantly different compared with the control group (p = 0.951). In advanced analyses, it was found that more severe TBUT, CFS, and OSDI scores were detected in the high NLR group (NLR ≥2.145, p = 0.003, 0.013, and 0.017, respectively) compared with the low NLR group (NLR <2.145). Conclusion The NLR value, but not PLR, of DED patients was higher than that of healthy controls. The NLR could be used as an inflammatory predictor to estimate the severity of DED.

Abstract
OBJECTIVE To investigate the monocyte-to-HDL-cholesterol ratio (MHR), neutrophil to lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), eosinophil-to-lymphocytes ratio (ELR), platelet distribution width (PDW), red blood cell distribution width (RDW), mean platelet volume (MPV), MPV to platelet count ratio (MPV/PC), and RDW to platelet ratio (RPR) that are accepted as inflammatory markers in patients with keratoconus. METHODS In this study, 43 patients with keratoconus and 43 healthy individuals as the control group were retrospectively evaluated. High density lipoprotein cholesterol (HDL-c), lymphocyte, neutrophil, eosinophil, monocyte, platelet, MPV, PDW, and RDW values were obtained with complete blood count performed on the peripheral blood samples. RESULTS Absolute monocyte (593 ± 182 vs 492 ± 177; p < 0.05) and neutrophil (4860 ± 1553 vs 3954 ± 1297; p < 0.01) counts were statistically significantly higher in the keratoconus groups compared to the control group. MHR (13.18 ± 5.02 vs 9.88 ± 4.45; p < 0.01) and NLR (2.30 ± 0.87 vs 1.77 ± 0.61; p < 0.01) were statistically significantly higher and LMR (4.07 ± 1.67 vs 5.18 ± 2.06; p < 0.01) was significantly lower in the keratoconus group. As a result of univariate logistic regression analysis, it was observed that MHR and NLR were statistically significant relationship with keratoconus (p = 0.02 and p = 0.021) (Odds ratio = 5.41 (95% CI: 1.169-6.669) and Odds ratio:5.28 (95% CI: 1.024-6.321); respectively). No statistically significant difference was found between the groups in terms of PLR, ELR, RDW, MPV, PDW, MPV/PC, and RPR. Adjusting for age and gender, multivariate regression analysis revealed that MHR was the most significant parameter to demonstrate relationship with keratoconus (p = 0.025) (Odds ratio = 4.99 (95% CI: 1.019-6.332)). CONCLUSION MHR and NLR values considered as inflammatory markers were statistically significantly higher and LMR value was significantly lower in the keratoconus group. Among these values, MHR was the most reliable parameter.

Abstract
Purpose To evaluate the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) in patients with non-arteritic anterior ischemic optic neuropathy (NAION). Methods Fifty-six patients with NAION and 60 age-sex matched healthy controls were included in the study. Demographic characteristics and laboratory findings of the patients and the controls were obtained from the electronic medical records. NLR, PLR, MLR, and SII were calculated and compared between the groups. Cutoff values were also determined. Results Neutrophil, monocyte and platelet counts were higher in the NAION group than in the control group, but the difference was not statistically significant (p > 0.05). The mean NLR and SII were higher in the NAION group than in the control group (p = 0.004 and p = 0.011, respectively). In the receiver operating characteristic curve analysis, the areas under the curve for NLR were 0.67, and NLR >1.79 predicted NAION with a sensitivity of 71% and specificity of 59%. The areas under the curve for SII was 0.66, and SII of >417 predicted NAION with a sensitivity of 71% and specificity of 49%. There was no significant difference in PLR and MLR between the groups (p = 0.105 and p = 0.347, respectively). Conclusions The current study demonstrated that NAION patients had increased NLR and SII levels compared with control subjects. Elevated NLR and SII might serve as readily available inflammatory predictors in NAION patients.

Abstract
PURPOSE To compare parameters of systemic inflammation and serum lipid levels in patients with pterygium versus healthy individuals. METHODS Thirty-five patients with pterygium and 30 healthy individuals were enrolled as two respective groups in a retrospective study. The participants' complete blood count (CBC) parameters and levels of serum total cholesterol, low-density lipoprotein, high-density lipoprotein (HDL), and triglycerides (TG) were obtained from digital records and compared. Their neutrophil/lymphocyte, platelet/lymphocyte, and monocyte/HDL ratios were calculated and compared as well. As secondary outcomes, longitudinal length (LL), basal length (BL), and total area (TA) of pterygium among the patients were quantitatively measured by using ImageJ software. Correlations between serum parameters and pterygium measurements were analyzed. RESULTS Although between-group differences in CBC parameters and the ratios were not statistically significant, HDL levels were significantly lower (p = 0.014) and TG levels significantly higher (p = 0.031) among patients with pterygium than among the controls. A positive correlation was detected between the patient's age and the pterygium's BL (p = 0.002, r = 0.516), LL (p = 0.00, r = 0.547), and TA (p = 0.00, r = 0.515). Neutrophil levels negatively correlated with LL (p = 0.025, β = - 0.308) and TA (p = 0.002, β = - 0.420). CONCLUSION Local instead of systemic inflammation should be considered in the management of pterygium. Besides, decreased HDL levels may indicate systemic oxidative stress in patients with the condition.

Abstract
PURPOSE We aimed to evaluate whether the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and systemic immune inflammation index (SII) were associated with primary open-angle glaucoma (POAG). MATERIALS AND METHODS This retrospective case-control study included 240 patients with POAG and 300 age- and sex-matched control subjects. Complete ophthalmological examination and blood count measurements were performed for all subjects. RESULTS The values of NLR, PLR, and SII in the POAG group were significantly increased compared with the control group (p < 0.001; p = 0.012; p < 0.001). However, the LMR value was lower in the POAG patients than in the control group (p < 0.001). When we divided the subjects into different age and gender subgroups, the NLR and SII values in the POAG patients were always higher than those in the control group. In the comparison of laboratory parameters in POAG subjects stratified according to severity, we also found that NLR and SII increased with the severity. The receiver operating characteristic (ROC) analysis revealed that the areas under the ROC curve of NLR, PLR, LMR, and SII to predict patients with POAG were found to be 0.627, 0.569, 0.382, and 0.986, respectively. The best cutoff point of NLR was 1.998 with a sensitivity of 59.8% and a specificity of 63.0%, and the SII was 947.365 with a sensitivity of 95.4% and a specificity of 95.7%. Multivariable logistic regression analysis showed that NLR was positively associated with mean deviation; moreover, NLR and SII were independent indicators correlated with POAG (OR 1.502; 95% CI 1.227-1.839; p < 0.001; OR 1.02; 95% CI 1.009-1.021; p < 0.001). CONCLUSION We speculated that elevated NLR and SII might serve as readily available inflammatory predictors in POAG patients.

Abstract
The optical molecular imaging of inflammation is an emerging strategy for interventional medicine and diagnostics. The host's inflammatory response and adaptation to acute and chronic diseases provides unique signatures that have the potential to guide interventions. Thus, there are emerging a suite of molecular imaging and sensing approaches for a variety of targets in this area. This review will focus on two key cellular orchestrators that dominate this area, neutrophils and macrophages, with recent developments in molecular probes and approaches discussed.

Abstract
Purpose: Increased systemic/local inflammation and oxidative stress play a key role in the pathophysiology of pterygium, but there is limited information regarding routine hematological indices’ levels in patients with pterygium. In this study, we aimed to evaluate the levels of complete blood count parameters in patients with pterygium. Material and Method: In all, 61 patients with pterygium (pterygium group; mean age = 51.4 ± 13.8 years) and 55 healthy individuals (control group; mean age = 50.2 ± 13.1 years) were included in the study. Participants were given routine ophthalmic examinations; complete blood count parameters were assayed. Results: Compared to the control group, red cell distribution width level was significantly higher in patients with pterygium (p = 0.009), but the difference between the groups in terms of the other complete blood count parameters was not statistically significant. However, high-density lipoprotein cholesterol level was significantly lower in the pterygium group than control group (p = 0.015). In the pterygium group, low-density lipoprotein cholesterol levels were lower, but this difference was not statistically significant (p = 0.079). Conclusion: Red cell distribution width levels were significantly increased in patients with pterygium. Our data support the idea that inflammation cytokines and oxidative stress may play an important role in the pathogenesis of this disorder.

Abstract
The red blood cell distribution width (RDW) is a simple and inexpensive laboratory parameter that can be linked to oxidative stress, inflammation and microvascular flow resistance. For this research, we performed a large-sample case-control study to describe the relationships between the RDW and primary angle-closure glaucoma (PACG). A total of 1191 PACG patients (422 males and 769 females), who were divided into mild, moderate and severe PACG groups, and 982 healthy controls (344 males and 638 females) were recruited between January 2008 and June 2018. Detailed eye and physical examinations were performed for each subject. Based on the laboratory results, the mean RDW was significantly higher (p < 0.001) in the PACG group (13.01 ± 0.82%) than in the control group (12.65 ± 0.53%). Moreover, the mean RDW level was lower (p < 0.05) in the mild PACG group than in the moderate and severe PACG groups. The Pearson correlation analyses showed significant positive correlations between the mean deviation and the RDW (r = 0.141, p < 0.001) and the intraocular pressure and the RDW (r = 0.085, p = 0.004). After adjusting for the confounding factors, the logistic regression analyses indicated that the odds ratio for the PACG group was 2.318 (p < 0.001, 95% confidence interval 1.997, 2.690) when compared to the control group. Additionally, an increased RDW was associated with the PACG severity, and this trend was also observed in the gender and age subgroups. In summary, the results of our study showed that an elevated RDW was associated with PACG and its severity. If future studies confirm this relationship, the use of an RDW assessment may help to predict the PACG severity in each patient in order to better customise effective prevention treatments.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 56:207-214. [PMID: 30668341 DOI: 10.1016/j.phymed.2018.11.002] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Revised: 11/01/2018] [Accepted: 11/03/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Elevated intraocular pressure (IOP) is a major risk factor for glaucoma that has been found to induce matrix metalloproteinase-9 (MMP-9) activation and result in eventual retinal dysfunction. Proinflammatory cytokines such as monocyte chemoattractant protein-1 (MCP-1) and interleukin-1β (IL-1β) were also found to be involved in disease progression by mediating MMP-9 production. We previously reported that fungal derivative theissenolactone C (LC53) could exert ocular protective effects by suppressing neuroinflammation in experimental uveitis. PURPOSE The aim of this study was to investigate the retinoprotective effects of natural compound LC53 on the high IOP-induced ischemia/reperfusion (I/R)-injury model of glaucoma and its cellular mechanisms. METHODS A high IOP-induced I/R-injury model was manipulated by normal saline injection into the anterior chamber of the rat eye. MCP-1-stimulated monocytes and IL-1β-activated primary astrocytes were used to investigate the cellular mechanisms of LC53. Retinal function was evaluated with the scotopic threshold response (STR) and combined rod-cone response by electroretinography (ERG). As a positive control, rats were treated with memantine. MMP-9 gelatinolysis, mRNA expression and protein expression were analyzed by gelatin zymography, RT-PCR, and Western Blot, respectively. The phosphorylation levels of MAPKs and NF-κB p65 were tested by Western Blot. Additionally, the levels of inflammatory MCP-1 and IL-1β were determined by ELISA. RESULTS The present study revealed that LC53 preserved the retina functional deficiency assessed by scotopic threshold response (STR) and combined rod-cone response of ERG after high IOP-induced I/R injury. These retinal protective effects of LC53 were positively correlated with inhibitory activities in I/R injury-elicited ocular MMP-9 activation and expression. The increased level of MCP-1 was not affected, and the enhanced IL-1β production was partially reduced by LC53 in the retina after I/R injury. According to cellular studies, LC53 significantly and concentration-dependently abrogated MMP-9 activation and expression in MCP-1-stimulated THP-1 monocytes. We found the inhibitory activities of LC53 were through the ERK- and NF-κB-dependent pathways. In addition, LC53 dramatically suppressed IL-1β-induced MMP-9 activation and expression in primary astrocytes. The phosphorylation of 65-kD protein (p65) of NF-κB was substantially blocked by LC53 in IL-1β-stimulated primary astrocytes. CONCLUSION LC53 exerted a retinal protective effect through NF-κB inhibition and was highly potent against MMP-9 activities after high IOP-induced I/R injury, suggesting that LC53 would be a promising drug lead for glaucoma or related medical conditions attributed to retinal ischemia.

Abstract
This study was conducted to reveal the role of systemic low-grade inflammation by calculating the Neutrophil/Lymphocyte Ratio (NLR) in Vitreomacular Traction Syndrome (VMTS) of different etiologies. A retrospective examination was made of the medical records at a tertiary referral hospital. The study included 31 patients with diabetic VMTS, 27 patients with idiopathic VMTS, and 35 healthy subjects as the control group. The White Blood Cell (WBC) counts and Neutrophil-to-Lymphocyte Ratio (NLR) was compared. There were insignificant differences between the groups in terms of mean age and female/male ratio (P>0.05). The mean ± Standard Deviation (SD) of NLR was calculated as 2.43 ± 0.83 in the diabetic VMTS group, 2.38 0.96 in the idiopathic VMTS group, and 1.83 WBC: White blood cell; VMTS: Vitreomacular traction syndrome; SD: standard deviation; µL: microliter; fL: femtolitre; n: number. 0.52 in the control group (P=0.007). The values of the diabetic and idiopathic VMTS groups were significantly higher than those of the control group (P=0.002 and P=0.032, respectively). However, differences between the diabetic and idiopathic VMTS groups were insignificant (P=0.651). This study found significantly higher NLR in patients with diabetic and idiopathic VMTS than the control group. Elevated NLR could therefore be a potential indicator of VMTS, irrespective of the etiology.
