Abstract
Background Inflammation plays a significant role in the proliferation, migration, and differentiation of lens epithelial cells after cataract surgery, clinically manifested as posterior capsule opacification (PCO). This condition is typically treated with neodymium: yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy. Our objective is to evaluate the association between blood-derived inflammatory markers and the development of clinically significant PCO necessitating treatment with laser capsulotomy. Materials and Methods We conducted a retrospective review of charts for all patients who underwent Nd:YAG laser capsulotomy in our department between January 2021 and December 2022. The study included 70 patients who diagnosed with clinically significant PCO requiring treatment with Nd:YAG laser capsulotomy following cataract surgery, as well as 70 pseudophakic controls with no signs of PCO. Complete blood cell count parameters were obtained from medical records and the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) were calculated. Results The mean age of the Nd:YAG laser capsulotomy and control group was 71.83±8.46 and 72.27±9.98 years, respectively. The preoperative NLR scores for the Nd:YAG laser capsulotomy group (mean rank = 34.43) were statistically significantly higher than those of the control group (mean rank = 25.41) (p = 0.044). However, after adjusting for preoperative measurements, no statistically significant differences were observed between the groups for the other parameters. Conclusion Preoperative NLR scores were higher in patients who developed clinically significant PCO requiring treatment with Nd:YAG laser capsulotomy. This finding suggests that patients with elevated systemic inflammation may be at an increased risk of developing PCO following cataract surgery. Further research is needed to evaluate the role of systemic inflammation in the pathogenesis of PCO.

J Clin Med 2024; 13:1168. [PMID: 38398480 PMCID: PMC10889408 DOI: 10.3390/jcm13041168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 02/13/2024] [Accepted: 02/16/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND The etiology of keratoconus is unclear. Current evidence suggests that inflammatory and systemic mechanisms might play a role in its pathophysiology. The proper interaction of proteolytic enzymes-matrix metalloproteinases-and their specific tissue inhibitors (TIMPs) within the cornea is essential in maintaining its structure, transparency and healing processes. The aim of the study was to determine the concentration of the TIMPs TIMP-1, TIMP-2, TIMP-3, and TIMP-4 in the blood serum samples of patients with keratoconus compared to the control group. METHODS The study encompassed 132 patients, of which 83 people constituted the study group and 49 the control group. The concentration of selected TIMPs was determined using the Human Magnetic Luminex® Performance Assay method. RESULTS In the study group, the concentrations of TIMP-1 and TIMP-3 were statistically significantly reduced, and TIMP-2 and TIMP-4 increased compared to the control group. The analysis of individual TIMPs in terms of their usefulness as potential predictors of keratoconus showed high results of diagnostic sensitivity and specificity for all TIMPs, in particular for TIMP-1 and TIMP-2. CONCLUSION The above results may indicate systemic disturbances in the TIMPs regulation among keratoconus patients. High diagnostic sensitivity and specificity of all TIMPs, in particular TIMP-1 and TIMP-2, may confirm their participation in the etiopathogenesis of this disease.

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: 6] [Impact Index Per Article: 6.0] [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
BACKGROUND Recent studies have presented inflammatory features on keratoconus (KC) and many inflammatory markers are described in the tears of patients with this disease. The KC pathogenesis is still unknown just like the correlation with inflammatory patterns. However, environmental and genetic issues may be part of the progress of KC. In addition, some systemic features, such as allergy and obesity, seem to be related to the progression of KC. Our purpose was to evaluate the neuropeptides vasoactive intestinal peptide (VIP), neuropeptide Y (NPY), chemokines ligand 2 (CCL-2) and 5 (CCL-5), and interleukins 6 (IL-6) and 8 (IL-8) on corneal epithelial cells and blood of patients with KC and in healthy controls. In addition, the neutrophil-to-lymphocyte ratio (NLR) was evaluated to predict inflammation. METHODS This including prospective observational study included 32 KC patients who underwent corneal crosslinking (CXL) and 32 control patients who underwent photorefractive keratectomy (PRK). Patients' corneal epithelial cells were removed surgically, and blood (buffy coat) was analyzed. Samples in triplicate were evaluated on rt-PCR for neuropeptides (VIP e NPY), interleukins (IL-6 e IL-8), and chemokines (CCL-2 and CCL-5). RESULTS Our study showed statistically higher CCL-5 and IL-8 on corneal epithelial cells in patients with KC. Blood cells were statistically higher in VIP and NPY in the KC group. Interleukin-8 on blood cells was statistically significant in KC'S group; for CCL-2 and CCL-5 they were statistically lower in patients with KC compared with controls. NLR showed no difference between the groups. CONCLUSIONS Our data support the findings of other studies that suggested altering KC status, such as inflammatory corneal disease. The presence of IL-8 in the cornea and blood samples of KC's group suggested systemic disease with a possible local or repercussion action. Further studies are warranted to elucidate KC pathogenesis and its correlation to systemic disease.

Abstract
Inflammation may play a significant role in Keratoconus (KC), but the relationship between inflammatory markers and choroidal thickness (CT) is unknown. The purpose of this study was to evaluate serum inflammatory markers and correlate them with the choroidal profile of KC patients and control subjects. Forty patients with KC and 26 age-matched control subjects were enrolled in a cross-sectional case-control study. Choroidal profile was studied with a Spectralis Heidelberg apparatus and venous blood samples were collected. Neutrophil/lymphocyte ratio (NLR), monocyte/HDL ratio (MHR), platelet/lymphocyte ratio (PLR) and systemic immune inflammation index (SII) were calculated. Serum inflammatory biomarkers IL-1, IL-6 and TNF-alfa were also analyzed. KC group presented thicker choroids in each evaluated point when compared to the control group (subfoveal CT 417.38 ± 79.79 vs 299.61 ± 76.13, p < 0.001 for all measured locations). Mean values of NLR, PLR and SII were significantly higher in patients with KC (NLR p = 0.001; PLR p = 0.042; SII p = 0.007). Although KC patients presented higher mean levels of MHR, IL-1, IL-6 and TNF-α than control group, no significant differences were achieved. Positive correlations were found between subfoveal CT and NLR and SII (0.408, p = 0.001 and 0.288, p = 0.019 respectively). The results presented are in favor of a relationship between the increased CT and inflammatory mechanisms in KC patients. The elevated serum inflammatory indices NLR, SII and PLR provide additional evidence of a role for systemic inflammation in the pathophysiology of KC.

Abstract
PURPOSE To investigate the corneal bacterial microbiome in patients with keratoconus using next-generation sequencing and develop a new perspective on the pathogenesis of the disease. METHODS This prospective observational study included 10 patients with keratoconus who underwent corneal crosslinking procedure and 10 healthy controls who underwent photorefractive keratectomy. Patients included in the study were aged 18 years or older. The demographic and clinical characteristics of participants were recorded. Corneal epithelial samples were collected between March 2021 and June 2021. Isolated bacterial DNA from corneal epithelial samples was analyzed using 16 S ribosomal RNA gene analysis. The relative abundance rates at the phylum and genus levels were calculated. Alpha diversity parameters were assessed. RESULTS Eleven phyla and 521 genera of bacteria were identified in all participants. At the phylum level, Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes were most abundant in both groups. There were no statistical differences between the two groups except Bacteriodetes (p < 0.05). At the genus level, the relative abundance rates of twenty bacteria were significantly different between keratoconus and healthy corneas (p < 0.05). Aquabacterium was the most abundant genus in patients with keratoconus, while Shigella was the most abundant genus in healthy controls. Alpha diversity parameters were lower in patients with keratoconus, although the difference did not reach statistical significance (p > 0.05). CONCLUSIONS Our preliminary study revealed that there are similarities and differences in the corneal microbiome between keratoconus and healthy individuals. Further research is required on the relationship between the abnormal corneal microbiome composition and the pathogenesis of keratoconus.

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.

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: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [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 The role of inflammation in retinitis pigmentosa (RP) has been receiving additional attention. However, the association between inflammation and the clinical manifestations and complications of RP is still unclear. This study aimed to evaluate the neutrophil-to-lymphocyte ratio (NLR) of RP complicated with cataract and explore the correlations between the NLR and specific clinical features of RP. METHODS This retrospective study included 79 RP patients complicated with cataract (125 eyes) and 63 age- and sex-matched patients (63 eyes) with age-related cataract (ARC). Patients' ocular examination results were collected and complete blood count results were used to calculate NLRs. The correlations between the NLR of RP patients and the parameters of ocular examinations were analysed. RESULTS The NLRs of RP patients with cataracts were significantly higher than those of ARC (1.93 ± 0.83 versus 1.65 ± 0.59, p = 0.029). The NLRs increased with the severity of posterior subcapsular cataract (PSC), zonular deficiency, poor preoperative best-corrected visual acuity (LogMAR>1), and visual field defects. Analysis of receiver operating characteristic curves suggested that NLR > 1.36 could predict higher degrees (PSC area >3%, >P1) of PSC (p = 0.002, 95% CI, 0.672-0.934), and that NLR > 2.12 could predict zonular weakness (p = 0.002, 95% CI, 0.665-0.928) in RP. CONCLUSION The NLRs in RP patients with cataract are not only higher but also associated with several clinical manifestations of RP. The NLR can be a predictive biomarker of higher degrees of PSC (>P1) and zonular weakness in RP before cataract surgery. These results suggest that systemic inflammation may play a role in the pathogenesis of RP.

Relationship of Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratio With Visual Acuity After Surgical Repair of Open Globe Injury. Front Med (Lausanne) 2021; 8:697585. [PMID: 34881251 PMCID: PMC8645644 DOI: 10.3389/fmed.2021.697585] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 10/25/2021] [Indexed: 11/25/2022] Open
Abstract
Purpose: To assess the relationship and prognostic value of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with poor final best-corrected visual acuity (BCVA) after surgical repair of open globe injuries (OGI) in adults. Design: Retrospective analysis of data from an ongoing prospective cohort of consecutive patients. Methods: In a tertiary university hospital, 197 eyes of 197 patients were included between 2013 and 2017. NLR and PLR were obtained from pre-operative blood tests to analyze its relationship with poor final BCVA. Results: Severe visual impairment (SVI) was defined as ≤20/200, and was observed in 96 (48.7%) patients after surgical repair of OGI. SVI patients had higher NLR (7.4 ± 6.6 vs. 4.0 ± 3.2, p < 0.001), and PLR (167 ± 92 vs. 139 ± 64; p = 0.021) than non-SVI. NLR ≥ 3.47 and PLR ≥ 112.2 were the best cut-off values for SVI, were univariate risk factors for SVI, and had sensitivity: 69.0, 71.4, and specificity: 63.6, 44.8, respectively. In multivariate analysis, only OTS, athalamia, and hyphema remained as risk factors. NLR had significant correlation with ocular trauma score (OTS) (r = −0.389, p < 0.001) and final BCVA (r = 0.345, p < 0.001). Limitations: Simultaneous trauma in other parts of the body that could influence the laboratory findings. Conclusion: Patients with SVI after a repaired OGI had increased pre-operative NLR and PLR levels. High NLR and PLR are risk factors for SVI in univariate analysis. It is confirmed that low OTS is a risk factor for SVI. High NLR and PLR could be used as a prognostic tool to identify patients at higher risk for SVI after repair of OGI.

Abstract
Inflammatory factors have been considered to contribute to keratoconus (KC) pathogenesis. This study aims to determine the immune cells subsets and soluble inflammatory factor profile on the ocular surface of KC patients. 32 KC subjects (51 eyes) across different grades of severity and 15 healthy controls (23 eyes) were included in the study. Keratometry and pachymetry measurements were recorded. Ocular surface immune cells (collected by ocular surface wash) immunophenotyped using flow cytometry include leukocytes, neutrophils, macrophages, natural killer (NK) cells, pan-T cells, gamma delta T (γδT) cells and NKT cells. Tear fluid collected using Schirmer's strip was used to measure 50 soluble factors by multiplex ELISA. Proportions of activated neutrophils, NK cells and γδT cells were significantly increased in KC patients. Significantly higher levels of tear fluid IL-1β, IL-6, LIF, IL-17A, TNFα, IFNα/β/γ, EPO, TGFβ1, PDGF-BB, sVCAM, sL-selectin, granzyme-B, perforin, MMP2, sFasL and IgE, along with significantly lower levels of IL-1α and IL-9 were observed in KC patients. Alterations observed in few of the immuno-inflammatory parameters correlated with grades of disease, allergy, eye rubbing and keratometry or pachymetry measurements. The observation implies a distinct immuno-inflammatory component in KC pathogenesis and its potential as an additional therapeutic target in KC management.

Abstract
PURPOSE It was aimed to compare the levels of inflammation-related parameters, such as neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR), in patients with advanced keratoconus (KC) and healthy controls. Also, we evaluated the relationships between these parameters and several corneal topography values used in the KC diagnostic index. METHODS Forty patients with advanced and 40 healthy volunteers were included in this study. In the KC group, 20 patients were nonprogressive KC and 20 patients were progressive KC. In all participating individuals, we evaluated detailed ophthalmologic examination findings and complete blood count data, while corneal topographic measurements were also recorded in patients with KC. RESULTS The mean NLR value was 2.3 ± 1.19 in the progressive KC group; nonprogressive KC values were 1.99 ± 1.69 and 1.81 ± 0.72 in the control group. Mean PLR value was 113.24 ± 48.44 in the progressive KC group, nonprogressive KC values were 96.47 ± 31.04 and 104.09 ± 35.14 in the control group. No statistically significant difference was found between patients with progressive KC, nonprogressive KC, and healthy volunteers in terms of mean NLR and PLR values (P > 0.05). NLR values were found to demonstrate significant positive correlations with the corneal topography parameters, Symmetry Index front (r = 0.278, P = 0.025), KC Vertex front (r = 0.247, P = 0.048), and Baiocchi Calossi Versaci front (r = 0.273, P = 0.028); there was no significant relationship between corneal topography parameters and PLR values. CONCLUSION Although there was no significant difference between the progressive KC, nonprogressive KC, and control groups in inflammation parameters such as NLR and PLR, a positive correlation was observed between the NLR value and some corneal topography findings used in the diagnosis of KC. The role of inflammation in the etiology of KC can be better understood by clinical studies and laboratory tests conducted with prospective studies involving a higher number of patients.

Abstract
PURPOSE To evaluate systemic inflammatory parameters in patients with corneal graft rejection after low-risk penetrating keratoplasty. METHODS Patients undergoing penetrating keratoplasty with indications of keratoconus, pseudophakic bullous keratopathy, and Fuchs endothelial dystrophy were analyzed retrospectively. Patients who had an endothelial rejection attack within two years post-transplant were included in the rejection group (n = 20), whereas patients with at least two years of post-transplant follow-up without graft rejection or failure were included in the control group (n = 46). All patients' clinical features and preoperative laboratory parameters were obtained from hospital records. The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio, and platelet-to-lymphocyte ratio of the groups were calculated and compared. RESULTS There was no difference between the two groups in terms of age, sex, indication, postmortem time and storage time of grafts, graft diameter, follow-up time, and common systemic diseases (p > 0.05). The NLR was found to be significantly lower in the rejection group when compared with the control group (2.04 ± 1.17, 2.66 ± 0.91, respectively, p = 0.023). There was no significant difference between the groups in terms of MLR and PLR (p = 0.243, p = 0.101, respectively). CONCLUSIONS Although a high NLR value, which is an indicator of systemic inflammatory condition, is associated with many ocular diseases, NLR was found to be lower in patients with a rejection episode after transplant surgery when compared with the control group. Further studies are needed to clarify the role of these hematologic parameters in graft rejection.

Abstract
Purpose: The aim of this study was to assess the systemic immune-inflammation index (SII) levels, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) in patients with keratoconus (KC). Methods: A total of 42 patients with KC (KC group) and 42 age- and sex-matched healthy subjects (control group) were included into this cross sectional study. Complete blood count parameters were assayed. SII, NLR, red cell distribution width (RDW), and PLR values were calculated. The SII value was calculated as follows: platelet count × (neutrophil/lymphocyte). Results: SII, NLR, RDW, and PLR values were significantly higher in KC group compared to control group [709 ± 236 vs. 418 ± 117 (P < 0.001), 2.5 ± 0.8 vs. 1.76 ± 0.3 (P < 0.001), 14.3 ± 1.6% vs. 12.9 ± 0.54% (P < 0.001), and 143 ± 36 vs. 106 ± 23 (P < 0.001), respectively]. Using the receiver operating characteristics (ROC) curve analysis to predict KC, the highest area under the curve (AUC) was determined SII (0.846 for SII, 0.778 for NLR, and 0.796 for PLR). Conclusion: SII, NLR, RDW, and PLR levels were significantly increased in patients with KC. This study supports the idea that several inflammatory pathways may play important role in the pathogenesis of this disorder. SII may be much better marker than NLR and PLR for predicting the inflammatory status of the disease.

Abstract
Purpose: The aim of this study was to investigate the role of inflammation in the pathogenesis of idiopathic intracranial hypertension (IIH) using the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as inflammation markers. Methods: The files of 33 IIH patients and 33 controls were screened for this retrospective study. For each patient, the NLR and PLR values were calculated using a single fasting blood sample. For both eyes, papilledema (PE) grades, best-corrected visual acuity (BCVA), retinal nerve fiber layer thickness (RNFLT), and ganglion cell layer thickness (GCLT) measurements were recorded along with the demographic data, including body mass index (BMI), and complete neurological and ophthalmological findings. Comparisons between the two groups and between the IIH patients with and without PE were made. The associations of NLR and PLR with all other parameters were analyzed independently from age, gender, and BMI. Results: NLR and PLR were higher in patients with IIH than controls (P < 0.05). They were also higher in patients with PE (P < 0.05) in the IIH group. NLR and PLR were found to be associated with BCVA (P < 0.001 and P = 0.023, respectively), global RNFLT (P = 0.004 and 0.012, respectively), RNFLT of the temporal quadrant (P < 0.001 and P = 0.042, respectively) and PE grade (P < 0.001 and P = 0.035, respectively). Conclusion: The NLR and PLR values and their associations with BCVA, RNFLT, and PE support the hypothesis that inflammation is a very important component of the pathogenesis of IIH.

Abstract
Purpose To assess the role of inflammation in the pathogenesis of idiopathic epiretinal membrane (iERM) using the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) as indicators of inflammation and to compare these parameter levels between iERM and control subjects. Methods We retrospectively analyzed the medical records of 36 patients who underwent vitrectomy-ERM peeling and 39 patients who had cataract surgery. We obtained blood samples from all individuals who participated in the study to investigate these parameters. Results Seventy-five subjects were included in this study: 36 in the iERM group and 39 in the control group. The mean neutrophil and MPV levels were significantly higher in iERM subjects than in control subjects. The mean lymphocyte level was lower in the iERM group. The mean NLR, PLR, and MPV levels were higher in iERM subjects than in control subjects. Conclusion The higher NLR, PLR, and MPV levels found in patients with iERM may indicate that subclinical systemic inflammation may associate with iERM.

[PMID: 33790566 PMCID: PMC8001663 DOI: 10.2147/tcrm.s298156] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 03/05/2021] [Indexed: 12/14/2022] Open
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
BACKGROUND The present study was conducted to investigate the association between haematologic indices, neutrophil/lymphocyte ratio (NLR), mean platelet volume (MPV), platelet/lymphocyte ratio (PLR), disease activation, organ involvement, and inflammatory markers in the SS. METHODS The study was conducted with newly diagnosed and treatment-naive 41 primary SS patients who met ACR-2012 criteria and 96 healthy volunteers. Blood tests obtained before treatment were evaluated. Lymphocyte, neutrophil and platelet counts, mean corpuscular volume (MCV), platelet distribution width (PDW), plateletcrit (PCT), haematocrit (HCT), MPV, white blood cell count (WBC) values were harvested from CBC of the subjects and NLR, PLR were calculated over these values. The values were compared between groups and correlation with EULAR SS disease activity index (ESSDAI) was evaluated. RESULTS The study included a total of 41 patients with a mean age of 40.73 ± 12.0 years and 96 healthy subjects with a mean age of 40.0 ± 9.2 years. In inter-group comparisons, lymphocyte, platelet counts, and MPV values were significantly lower in the SS group compared with the control group (P < .01), and NLR was significantly higher in the SS group (P = .026). The mean ESSDAI scores in SS patients were 5.65 ± 0.86 SE. These scores were significantly higher in patients with neurological involvement. There was a positive correlation between ESSDAI and PLR. CONCLUSION NLR, PLR, and MPV may be used as indicators or with activity index in SS. ESSDAI scores were found to be high in patients with neurological involvement, and it was also found to be correlated with PLR.

Abstract
OBJECTIVE To evaluate inflammatory indices of complete blood count (CBC) in patients with Fuchs uveitis syndrome (FUS), and to compare the results with healthy individuals. DESIGN Cross-sectional, comparative study. PARTICIPANTS A total of 140 participants were included in the study and divided into 2 groups: 70 patients diagnosed with FUS (FUS group) and 70 healthy individuals (control group). METHODS The groups were compared in terms of ocular examination findings and CBC parameters. The independent samples t test was used to examine variables between the groups. The Pearson correlation test was performed to analyze correlation among the severity of anterior chamber reaction, duration of FUS, and CBC indices. RESULTS The mean lymphocyte count and lymphocyte-to-monocyte ratio (LMR) were significantly higher in the FUS group than in the control group (p = 0.001 and p < 0.001, respectively). The mean monocyte count and neutrophil-to-lymphocyte ratio (NLR) were significantly lower in the FUS group than in the control group (p = 0.010 and p = 0.003, respectively). In the receiver operating characteristic curve analysis, the area under the curve (AUC) for LMR was 0.834, with a sensitivity of 82.6% and a specificity of 80.0%. The AUC for NLR was 0.789, with a sensitivity of 71.2% and a specificity of 70.0%. LMR was positively correlated with duration of FUS (p = 0.001, r = 0.574). CONCLUSIONS Our findings suggest that decreased NLR and increased LMR values may be markers indicating impaired blood-aqueous barrier function in FUS.

Increased choroidal thickness is not a disease progression marker in keratoconus. Sci Rep 2020; 10:19938. [PMID: 33203915 PMCID: PMC7673983 DOI: 10.1038/s41598-020-77122-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Accepted: 11/03/2020] [Indexed: 11/27/2022] Open
Abstract
The recent findings of increased Choroidal Thickness (CT) in Keratoconus (KC) patients raised the question of whether CT could be an indicator of progressive KC. To test this hypothesis, we evaluated and compared the choroidal profile in progressive and non-progressive KC. We ran a cross-sectional observational study in 76 patients diagnosed with KC, age 14–30, to assess KC progression. Progression was defined as when at least two of the studied variables confirmed progression (Kmax, Km, PachyMin, D-Index, Astig, K2, 3 mm PCR). Included patients performed a Spectralis Optical Coherence Tomography (OCT) with enhanced depth image (EDI) technology to evaluate choroidal profile. Choroidal measurements were taken subfoveally and at 500 µm intervals from the fovea, in 7 different locations, and compared between groups. Multivariate linear regression analyses were also performed to assess the influence of CT in KC progression. Thirty-six eyes (47.4%) were classified as KC progressors. The mean subfoveal CT observed in the total sample was 382.0 (± 97.0) μm. The comparison between groups (progressive and non-progressive KC) showed no differences in the locations evaluated (mean subfoveal CT difference between groups was 2.4 μm, p = 0.915). In the multivariate analysis CT seems not be influenced by KC progression (B = 6.72 μm, 95% CI − 40.09 to 53.53, p = 0.775). Assessment of choroidal profile does not appear to be a useful tool to differentiate progressive and non-progressive KC. Further research is needed in order to better understand the role of choroid in KC.

Abstract
The purpose of this study was to evaluate the monocyte to high-density lipoprotein (HDL) ratio (MHR) in patients with arteritic anterior ischaemic optic neuropathy (A-AION) and non-arteritic anterior ischaemic optic neuropathy (NA-AION). A total of 98 subjects were included in the study. Patients were divided into three groups: 16 patients with A-AION regarded as group one; 41 patients with NA-AION regarded as group two and 41 healthy subjects regarded as the control group. The MHR was calculated in all participants and compared between the patient and control groups. The mean age of subjects with A-AION, NA-AION and the control group were 75.9 ± 8.9 years, 67.1 ± 9.2 years, and 66.6 ± 6.7 years, respectively. Baseline clinical characteristics, such as diabetes mellitus and hypertension, were similar among groups. The mean MHR was significantly higher only in the A-AION group compared with the NA-AION and control group (p < .001), whereas there was no difference between NA-AION group and control group (p = .110). On receiver operating characteristic analysis, the area under the curve was 0.755, and the best cut- off value was 12.2 with a sensitivity of 72% and a specificity of 80%. An elevated MHR ratio is significantly associated with A-AION and MHR might be used to differentiate A-AION from NA-AION.

Abstract
AIM To evaluate the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in idiopathic epiretinal membrane (IERM) patients, and their relations with visual acuity. METHOD Fifty-seven IERM and 51 control patients were included. All patients underwent comprehensive ophthalmological examination and complete blood count tests, and NLR and PLR values were calculated. Patients with IERM were compared with the control group, and associations with visual prognosis were evaluated. These ratios' cut-off values for IERM were also calculated RESULTS: NLR values were statistically significantly higher in the IERM group than in the control group (p = 0.001). No significant difference was observed between the IERM and control groups in terms of PLR (p = 0.43). No significant correlation was determined between visual acuity and NLR or PLR (r = 0.05, p = 0.66; and r = 0.18, p = 0.16, respectively). The cut-off value for NLR was 1.91. CONCLUSION Patients with IERM showed significantly increased NLR compared to control subjects suggesting that IERM patients may be prone to have high NLR values.

Abstract
PURPOSE To compare complete blood count (CBC) parameters and neutrophil/lymphocyte ratio (NLR) between patients with infectious uveitis (IU) and those with non-infectious uveitis (NIU) during the first acute uveitis attack (AUA). METHODS The records of 119 patients admitted with the first AUA between 2016 and 2019 and whose diagnosis was unknown at the time of admission were retrospectively reviewed. The patients were divided into two groups, IU and NIU according to diagnoses after ocular and systemic workup. The IU group was also divided into subgroups as uveitis associated with local ocular infections and systemic infections. The complete blood count and associated indices of patients calculated from samples taken during the attack were compared between the groups. RESULTS A total of 60 NIU cases (mean age: 43.5 ± 11.6 years) and 59 IU cases (43.3 ± 14.7 years) were examined. Twenty-six of the NIU cases were female and 34 were male, while 32 of the IU cases were female and 27 were male. The localization of uveitis was similar in the IU and NIU groups (anterior: 11 vs. 18, intermediate: 3 vs. 6, posterior: 28 vs. 14, panuveitis: 17 vs. 22). The NLR values were significantly increased in patients with IU compared to those with NIU (p = 0.047). When the NLR is compared between NIU and subgroups of IU, this value was only found significantly increased in uveitis due to a systemic infection (n = 12) (p < 0.001). The mean white blood cell (WBC) count (p < 0.001) and neutrophil values (p < 0.001) were also observed significantly higher in the uveitis associated with systemic infectious diseases when compared with uveitis associated with local ocular infections and NIU group. CONCLUSION In the current study, NLR values are compared with autoimmune uveitis and systemic infectious uveitis for the first time in patients with AUA. This ratio has been found significantly higher in uveitis associated with systemic infections. The use of CBC parameters and indices, especially the NLR, may be instrumental in assessing patients presenting with first AUA, particularly when there is no clear explanation or underlying cause.

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: To find immunomediator combinations which could sensitively indicate keratoconus progression.Methods: Tear samples of 42 patients with keratoconus were collected at baseline and at the end of a one-year follow-up. The concentrations of 13 mediators were measured by CBA. Based on Pentacam HR examination, eyes were divided into a non-progressive and a progressive group.Results: At the end of the follow-up, significant differences were observed in the release of IFNγ, IL-13, IL-17A, CCL5, MMP-13 and PAI-1 between the two groups. Changes in five Pentacam parameters correlated positively with changes in IFNγ, IL-13, IL-17A, CXCL8, CCL5, TIMP-1 and t-PA. We found that tear level of IL-13 in combination with NGF can predict the progression of keratoconus with 100% specificity and 80% sensitivity.Conclusion: The findings of our longitudinal study may underscore the importance of NGF and IL-13 tear levels in the prediction of keratoconus progression.

Abstract
Purpose: To evaluate whether the C-reactive protein (CRP)/albumin ratio (CAR) in patients with uveitis during an attack is a marker that can give information about the activity, severity and prognosis of the disease.Methods: This study included 35 patients with an uveitis attack and 35 healthy volunteers. The localization and severity of uveitis were recorded. Patients' complete blood count (CBC) during the attack, CRP, CAR, erythrocyte sedimentation rate(ESR), neutrophil/lymphocyte ratio(NLR), and platelet/lymphocyte ratio(PLR) were recorded.Results: The mean age was 34.1 ± 12.5 years for the 35 uveitis cases and 30.1 ± 4.1 years for the healthy volunteers. CRP and CAR were significantly higher in uveitis patients (p = .015 and 0.011, respectively). While CRP and CAR were significantly higher in severe anterior uveitis than mild anterior uveitis (p = .036 and 0.022, respectively), only CAR was significantly higher in severe posterior and panuveitis than mild ones(p = .017).Conclusion: CAR may be an important parameter in determining the activation of the uveitis.

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
AIM To summarize the results of studies investigating neutrophil-to-lymphocyte ratio (NLR) and to identify the role of NLR in ocular diseases. METHODS With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.

Abstract
Purpose To analyze and compare choroidal thickness between keratoconus (KC) patients and age-matched non-KC subjects. Methods A cross-sectional, case-control study. One hundred and thirty-four keratoconic eyes and 78 control eyes, from individuals aged from 12 to 30 years old, were studied. Patients with KC followed in Corneal Department of Centro Hospitalar São João, Porto, Portugal, were identified and consecutively included between December 2017 and February 2018. A spectral-domain optical coherence tomography (OCT) using depth enhanced imaging was performed, and choroidal thickness in the center of the fovea and at 500 μm intervals along a horizontal section was measured and compared. Results The statistical analysis showed that keratoconic eyes present a thicker choroid in every measured location (p < 0.05). Mean subfoveal choroidal thickness (SFCT) values obtained were 375.86 ± 89.29 and 322.91 ± 85.14 in keratoconus and control groups, respectively (p < 0.001). In a multivariate analysis, SFCT was significantly associated with spherical equivalent (p=0.004) and the presence of keratoconus (p < 0.001), but not with age (p=0.167), gender (p=0.579), or best-corrected visual acuity (p=0.178). In a "fixed model," keratoconus patients were found to have a 67.55 μm (95% CI 36.61-98.49) thicker subfoveal choroid compared to controls. Conclusion Keratoconus patients seem to have a thicker choroid than healthy individuals. The exact pathophysiological mechanism resulting in a thicker choroid in KC patients is not known, but it could possibly be associated with inflammatory choroidal mechanisms.

Abstract
BACKGROUND To evaluate the association between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and the development of retinal vein occlusion. METHODS One hundred and eleven patients and 88 control subjects were enrolled. Retinal vein occlusion diagnosis was clinically made with fundus examination. NLR and PLR values were compared between groups. RESULTS Neutrophil levels were found to be comparable between the two groups (p = 0.47). Lymphocyte levels were lower in retinal vein occlusion patients (p = 0.001). NLR was significantly higher in retinal vein occlusion patients (p = 0.001). Platelet counts were found to be comparable in the two groups (p = 0.75). PLR was significantly higher in retinal vein occlusion patients (p = 0.001). According to the receiver operating characteristic curve analysis, the optimal cut-off values of NLR and PLR to predict retinal vein occlusion were > 1.63 and > 98.50, respectively. CONCLUSIONS The present study showed that higher NLR and PLR were associated with the development of retinal vein occlusion. Also, NLR and PLR may be used as predictive tools for identifying risk for retinal vein occlusion.

Abstract
OBJECTIVE To evaluate monocyte/high-density lipoprotein cholesterol ratio (MHR) and neutrophil/lymphocyte ratio (NLR) in patients with keratoconus (KC). METHODS Thirty-one patients with KC (group 1) and 31 healthy control subjects (group 2) were included in the study. All participants' ocular examination findings, clinical and laboratory parameters were obtained from file records and laboratory archives. RESULTS When group 1 was compared with group 2, MHR (13.7 ± 5.0 vs. 9.1 ± 3.7; p < .001) and NLR (2.3 ± 0.8 vs. 1.7 ± 0.6; p < .001) were statistically significantly higher in group 1. Optimal MHR cutoff value for KC was calculated as 10.2 with 77.4% sensitivity and 64.5% specificity, and optimal NLR cut-off value for KC was found as 1.9 with 71.4% sensitivity and 55% specificity. CONCLUSION MHR and NLR values recognized as indicators of oxidative stress and systemic inflammation were significantly higher in patients with KC compared to the control group.

Abstract
Purpose: To investigate the relation between high axial myopia and neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) values.Methods: Seventy-nine cases were enrolled, 50 myopic and 29 emmetropic. All participants were assigned into three groups: Group I (high myopia with no retinal involvement), Group II (high myopia with retinal involvement) and Group III (control). NLR and PLR values calculated from blood tests were compared among the groups.Results: Mean NLR levels were 2.23 ± 0.78 in Group I, 2.36 ± 1.06 in Group II, and 1.57 ± 0.33 in Group III. Mean PLR levels were 114.62 ± 23.21 in Group I, 145.16 ± 52.36 in Group II, and 91.42 ± 18.73 in Group III. NLR and PLR values in the high myopia groups were significantly higher than in the control group.Conclusion: NLR and PLR values in cases with high axial myopia were higher than in the emmetropic group. Higher inflammation in the degenerative myopic group in particular may be related to pathological chorioretinal changes.

Abstract
Objectives: The aim of this study was to evaluate the neutrophil-to-lymphocyte ratio (NLR) and the mean platelet volume (MPV) in patients with active thyroid orbitopathy (TO) and to compare it with that of both healthy subjects and patients with inactive TO. Methods: Twenty patients with active TO (Group 1), 25 patients with inactive TO (Group 2), and 35 age- and sex-matched healthy subjects (Group 3) were included in this study. Patients with other systemic and ocular diseases, patients with a history of intraocular or orbital surgery, and patients using systemic drugs were excluded. The VISA (vision, inflammation, strabismus, appearance) classification scheme was used to discriminate between active and inactive TO. The neutrophil and lymphocyte counts and the MPV of all participants were recorded. The NLR was calculated by dividing the neutrophil count by the lymphocyte count, and the result was compared between groups. The optimal cut-off value was determined for NLR and MPV and the data were compared with a one-way analysis of variance test and the ’Bonferroni post-test. Results: The mean age was 45.4±13.4, 41.0±13.7, and 42.6±14.4 years in Group 1, 2, and 3, respectively (p=0.68). The NLR was 2.11 in Group 1, 1.56 in Group 2, and 1.47 in Group 3 (p=0.03). The ’Bonferroni post-test revealed a difference between Group 1 and Group 2 (p=0.01) and between Group 1 and Group 3 (p<0.001). The MPV was 10.76 fL in Group 1, 9.94 fL in Group 2, and 8.19 fL in Group 3 (p<0.001). The results of the ’Bonferroni post-test showed a difference between Group 1 and Group 2 (p=0.04), between Group 1 and Group 3 (p<0.001), and between Group 2 and Group 3 (p<0.001). The mean cut-off value obtained from receiver operating characteristic (ROC) analysis of NLR was 1.69 (sensitivity: 72%; specificity: 66%). The mean cut-off value obtained from ROC analysis of MPV was 9.95 (sensitivity: 63%; specificity: 66%). Conclusion: High NLR and MPV values may be indicative of active inflammation in patients with TO.”

Abstract
The aim of this study was to assess the possible relationship between AAION (arteritic anterior ischemic optic neuropathy) and NAION (non-arteritic anterior ischemic optic neuropathy) with blood platelet parameters and NLR (neutrophil-to-lymphocyte ratio). The medical records of 12 patients with AAION, 33 patients with NAION, and 35 healthy subjects were examined. MPV, PDW, and PCT values showed marked elevation in AAION and NAION groups compared with control group. The mean NLR was statistically significantly higher only in AAION group compared to the NAION and control groups, suggesting that platelet function plays an important role in AIONs and NLR might be used to differentiate AAION from NAION.

Abstract
Inflammation may play a significant role in Keratoconus (KC), but the implication of immunity on this inflammatory response is unknown. Therefore, our aim was to determine the expression levels of Toll-like receptors 2 (TLR2) and 4 (TLR4) in monocytes and neutrophils from patients with KC and control subjects for demonstrating the role of innate immunity in KC. We also study the correlation between TLR2/TLR4 expression and serum levels of proinflammatory markers (IL-1β, IL-6, TNF-α, MMP-9 and NF-κB). Forty patients with bilateral KC (55% males; mean age; 33.1 ± 10.9 years) and 20 control subjects (55% males; mean age; 30.4 ± 7.6 years) were included in the study. Our results showed that mean expression of TLR2 and TLR4 in both neutrophils and monocytes was significantly higher in patients with KC compared to control subjects (all p < 0.0001). Furthermore, KC patients also showed higher serum levels of IL-1B, IL-6, TNF-α, MMP-9 (all p < 0.0001) and NF-κB (p = 0.036). In addition, we found a strong correlation between TLR2 expression in both monocytes and neutrophils (all p < 0.0001), and TLR4 in monocytes (all p < 0.05) with serum levels of IL-1B, IL-6, TNF-α and MMP-9. In conclusion, these findings suggest that TLRs may play an important role in the pathophysiology of KC.

Abstract
PURPOSE We aimed to assess the levels of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in patients with primary open-angle glaucoma (POAG) and to compare the NLR and PLR results of patients with POAG and ocular hypertension, as well as in healthy controls. PATIENTS AND METHODS Eighty-four patients with POAG, 94 patients with ocular hypertension, and 80 healthy subjects were enrolled in this retrospective study. Complete ophthalmological examination and complete blood count measurements were performed for all subjects. RESULTS There was a significant difference in the NLR (P=0.003) and PLR (P=0.049) between POAG and control groups. In addition, there was a correlation between pattern standard deviation and NLR in the POAG group. The receiver operating characteristics analysis revealed that the value of NLR to distinguish patients with POAG and controls was found to be 0.651. The best cutoff value was 2.1, with a sensitivity of 65% and a specificity of 65%. CONCLUSIONS Our study for the first time provides evidence that NLR and PLR may be useful as biomarkers in patients with POAG.

Abstract
PURPOSE To assess the levels of neutrophil-to-lymphocyte ratio (NLR) in patients with idiopathic epiretinal membrane (iERM) and to compare the NLR results of patients with iERM and healthy controls. METHODS This retrospective study enrolled 43 patients with iERM and 40 healthy subjects. Complete ophthalmologic examination and complete blood count measurements were performed of all subjects. Complete blood counts were performed within 2 h of blood collection. RESULTS There was a significant difference in NLR between iERM and control groups (p < 0.01). The receiver operating characteristics analysis revealed that the value of NLR to distinguish patients with iERM and controls was found to be 0.832. The best cutoff value was 1.90, with a sensitivity of 72% and specificity 70%. CONCLUSIONS Our study for the first time provides evidence that subclinical systemic inflammation may cause or at least accompanies iERM using a novel biomarker NLR.

Med Hypotheses 2017; 103:54-56.

Abstract
As a type of primary open-angle glaucoma, normal-tension glaucoma (NTG) is a health problem that manifests itself with low intraocular pressure (IOP) levels and preserves its importance for public health care. In population-based screenings, which take the IOP levels of 21mmHg as a cut-off for the diagnosis of glaucoma, the diagnosis is usually delayed, and the treatment is started in an advanced stage by the referred ophthalmologists. NTG is associated with some autoimmune conditions and systemic diseases, such as paraproteinemia, nocturnal hypotension, and migraine. Recently, a simple and cheap test (namely the hemogram) was defined as measure of systemic inflammation, measuring the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). A recent study displayed an altered platelet function in NTG patients. We hypothesize that an automated hemogram analysis for NLR together with IOP measurements may be used to screen NTG patients who are admitted to primary care clinics if any relationship between NTG and NLR could be demonstrated in future researches.

Abstract
Purpose To evaluate the neutrophil to lymphocyte ratio (NLR) in patients with nonarteritic anterior ischemic optic neuropathy (NAION). Methods We investigated 112 subjects comprising 56 patients with NAION and 56 healthy controls at Süleyman Demirel University. Complete blood count, demographic, and clinic data from NAION patients were evaluated in this study. The NLR was calculated in all individuals and compared between the patient and control groups. Cut-off values were also determined. Then, the relationship between NLR and visual outcomes was investigated. Results The cut-off value for NLR was 1.64. NLR values were significantly higher in NAION patients than in healthy subjects (p < 0.001) and were directly correlated with erythrocyte sedimentation rate levels (r = 0.263, p = 0.006). Also, the NLR value was associated with visual outcomes. Receiver operator characteristic curve analysis revealed a 0.63 area under the curve (confidence interval, 53.7% to 74.1%), 85% sensitivity and 41% specificity at the cut-off NLR value. Conclusions The NLR may be a biomarker with good sensitivity that is quick, cost effective and easily detected in serum. It can be used in clinical practice to predict a NAION patient's prognosis in terms of visual outcomes.

Abstract
AIM To assess the levels of the neutrophil to lymphocyte ratio (N/L) and the platelet to lymphocyte ratio (P/L) in patients with idiopathic acute anterior uveitis (AAU) and to compare with healthy controls. METHODS Thirty-six male patients with idiopathic AAU and 36 male healthy subjects were enrolled in this retrospective study. Complete ophthalmological examination and complete blood count measurements results of all subjects were evaluated. RESULTS There was a significant difference in N/L and P/L between idiopathic AAU and control groups (P=0.006, P=0.022). Also, correlation analysis revealed a significant correlation between C-reactive protein (CRP) and N/L (P=0.002; r=0.461). CONCLUSION Our study for the first time provides evidence of N/L and P/L may be useful biomarkers in patients with idiopathic AAU. N/L is correlated with CRP, so it can be a useful biomarker to predict the prognosis in idiopathic AAU.

Abstract
Keratoconus (KC) is a corneal thinning disorder that leads to loss of visual acuity through ectasia, opacity, and irregular astigmatism. It is one of the leading indicators for corneal transplantation in the Western countries. KC usually starts at puberty and progresses until the third or fourth decade; however its progression differs among patients. In the keratoconic cornea, all layers except the endothelium have been shown to have histopathological structural changes. Despite numerous studies in the last several decades, the mechanisms of KC development and progression remain unclear. Both genetic and environmental factors may contribute to the pathogenesis of KC. Many previous articles have reviewed the genetic aspects of KC, but in this review we summarize the histopathological features of different layers of cornea and discuss the differentially expressed proteins in the KC-affected cornea. This summary will help emphasize the major molecular defects in KC and identify additional research areas related to KC, potentially opening up possibilities for novel methods of KC prevention and therapeutic intervention.

Abstract
Keratoconus is a degenerative disorder with progressive stromal thinning and transformation of the normal corneal architecture towards ectasia that results in decreased vision due to irregular astigmatism and irreversible tissue scarring. The pathogenesis of keratoconus still remains unclear. Hypotheses that this condition has an inflammatory etiopathogenetic component apart from the genetic and environmental factors are beginning to escalate in the research domain. This paper covers the most relevant and recent published papers regarding the biomarkers of inflammation, their signaling pathway, and the potentially new therapeutic options in keratoconus.
