Abstract
CLINICAL RELEVANCE Treatment with aromatase inhibitors (AIs) in patients with breast cancer can lead to dry eye disease (DED). BACKGROUND The purpose of the study is to determine the prevalence and risk factors of DED in patients treated with AIs for breast cancer. METHODS Participants in this cross-sectional study were patients with breast cancer treated with AIs. Demographic and clinical data, including age, sex, type of cancer, stage, grade, duration of treatment and adjuvant chemotherapy and/or radiotherapy were collected. All patients underwent a detailed ophthalmic examination, as well as Tear Break up Time (TBUT) and Schirmer test, while Ocular Surface Disease Index (OSDI) questionnaires were administered. Based on the clinical findings, a diagnosis of DED was made, and prevalence was calculated. Univariate analysis of the association of different variables with DED was performed. A logistic regression analysis was done to identify risk factors for DED among study population. RESULTS A total of 102 participants were included in the study. The mean age of patients was 62.4 ± 10.8 years. A total of 77 out of 102 patients (75.5%) had ductal, 16 (15.7%) lobular and 9 (8.8%) other types of breast cancer. A total of 83 patients (81.4%) received chemotherapy and 70 patients (68.6%) received radiotherapy. The mean duration of treatment was 24.4 ± 18.9 months. The prevalence of DED in the study sample was 69.6%. Patients who received radiotherapy (OR = 3.31, 95%CI = 1.30-7.82, p = 0.01) or were under treatment with AIs for more than 24 months (OR = 3.53, 95%CI = 1.47-9.21, p = 0.002) were found to have an increased risk of DED. CONCLUSION There was a high prevalence of DED among the study population. Radiotherapy and duration of treatment with AIs were independently associated with DED.

Abstract
PURPOSE The study aims to characterize the robustness of distinct clinical assessments in identifying the underlying conditions of dry eye disease (DED), with a specific emphasis on the involvement of conjunctival goblet cells. METHODS Seven rabbits receiving surgical removal of the lacrimal and Harderian glands were divided into two groups, one with ablation of conjunctival goblet cells by topical soaking of trichloroacetic acid (TCA) to the bulbar conjunctiva (n = 3) and one without (n = 4), and the conditions of DED were assessed weekly using Schirmer test, tear breakup time (TBUT), tear osmolarity, and National Eye Institute (NEI) fluorescein staining grading. After 8 weeks, the rabbits were sacrificed, and the eyes were enucleated for histopathological examination. RESULTS Histopathological analysis revealed corneal epithelial thinning in both groups. While TCA soaking significantly decreased the density of conjunctival goblet cells, DED rabbits without TCA also showed a partial reduction in goblet cell density, potentially attributable to dacryoadenectomy. Both groups showed significant decreases in Schirmer test and TBUT, as well as an increase in tear osmolarity. In DED rabbits with TCA soaking, tear osmolarity increased markedly, suggesting that tear osmolarity is highly sensitive to loss and/or dysfunction of conjunctival goblet cells. Fluorescein staining was gradually and similarly increased in both groups, suggesting that fluorescein staining may not reveal an early disruption of the tear film until the prolonged progression of DED. CONCLUSION The Schirmer test, TBUT, tear osmolarity, and NEI fluorescein grading are distinct, yet complementary, clinical assessments for the evaluation of DED. By performing these assessments in definitive DED rabbit models, both with and without ablation of conjunctival goblet cells, the role of these cells in the homeostasis of tear osmolarity is highlighted. Characterizing the robustness of these assessments in identifying the underlying conditions of DED will guide a more appropriate management for patients with DED.

Abstract
Purpose We aimed to determine the seasonal variation in the tear meniscus level on strip meniscometry and its association with ocular parameters and symptoms. In Japan, there are four distinct seasons characterized by marked differences in temperature and humidity, which may contribute to an observed seasonality of ocular surface symptoms. Methods We conducted a cross-sectional study in two Japanese clinics and recruited first-visit patients for 3 years. Tear strip meniscometry, tear break-up time (BUT), Schirmer test, and corneal staining were examined, and major ocular symptoms (dryness, irritation, pain, fatigue, blurred vision, and photophobia) were determined through interviews. Results The 1196 participants had a mean age of 58.9±15.2 years; 37.1% were of male sex. Strip meniscometry values and BUT revealed significant seasonality with one-way analysis of variance. The mean strip meniscometry value (mm) was 2.15±2.59 in spring (p=0.025 vs winter), 2.37±2.79 in summer (p<0.001), 2.38±2.80 in fall (p<0.001), and 1.64±2.29 in winter. Regression analysis indicated that strip meniscometry levels were correlated with BUT (p<0.001), Schirmer test values (p<0.001), corneal staining scores (p=0.022), and presence of dryness (p<0.001). Conclusion Strip meniscometry values exhibited distinct seasonality, being lowest in winter when the ambient condition is dry and cool, and were correlated with BUT, Schirmer test values, corneal staining scores, and the presence of subjective dryness.

Abstract
PURPOSE To assess the repeatability of corneal pachymetry and epithelial thickness measurements with spectral-domain optical coherence tomography (SD-OCT) and identify correlations between epithelial thickness and ocular surface parameters. METHODS Adults who happened to have prolonged computer use were recruited, excluding those with conditions interfering with corneal measurements or tear production. All subjects filled in the ocular surface disease index (OSDI) questionnaire. Three consecutive measurements of central and peripheral corneal and epithelial thickness were performed with SD-OCT (RTVue XR). Schirmer test I and tear film break-up time (TBUT) were performed. Repeatability was evaluated with intraclass correlation coefficient (ICC), coefficient of variation and repeatability limit. Spearman correlation was used for non-parametric variables. RESULTS 113 eyes of 63 subjects were included in the study. ICC was ≥ 0.989 for all corneal and ≥ 0.944 for all epithelial pachymetry segments. The best repeatability was found centrally and the worst superiorly both for corneal and epithelial measurements. Central epithelial thickness was weakly correlated with Schirmer test I (rho = 0.21), TBUT (rho = 0.02), OSDI symptoms and OSDI score (rho <|0.32|). OSDI symptoms and OSDI score were weakly correlated with Schirmer test I (rho <|0.3|) and TBUT (rho <|0.34|). CONCLUSION RTVue XR measurements of corneal and epithelial thickness are highly repeatable in all segments. The lack of correlation between epithelial thickness and ocular surface parameters could suggest the assessment of epithelial integrity with reliable methods such as SD-OCT.

Abstract
We aimed to evaluate the types and concentrations of trace elements in tears of individuals living in urban and rural environments using particle induced X-ray emission (PIXE) and the possible association with exposure to air pollution and suggest a novel method for tear-based biomonitoring studies. This cross-sectional pilot study comprised 42 healthy subjects, 28 living in a rural area and 14 in an industrial city. Tears were collected with Schirmer paper and characterized by PIXE. Trace element concentrations from both eyes were averaged together with environmental pollution data. Main outcome measures were between-group differences in types and concentrations of trace elements in tears and comparison to environmental data. The rural group included 12/28 men, mean age 45.2 ± 14.8 years. The urban group consisted of 11/14 men of mean age 27 ± 5.9 years. Six rural and all urban were active smokers. Air pollution data showed more toxic elements in the rural environment. On PIXE analysis, chlorine, sodium, and potassium were found in similar concentrations in all samples. Normalizing to chlorine yielded higher values of aluminum, iron, copper, and titanium in the rural group; aluminum was found only in the rural group. The higher levels of certain trace elements in the rural group may, in part, be a consequence of exposure to specific environmental conditions. No direct association was found with air pollution data. PIXE is useful to analyze trace elements in tears, which might serve as a marker for individual exposure to environmental pollutants in biomonitoring studies.

Abstract
Femtosecond laser-assisted in situ keratomileusis (Femto-LASIK) represents a common treatment modality in refractive surgery and shows excellent results in terms of safety, efficacy, predictability, and long-term stability. However, patients may be affected by dry eye symptoms. The aim of this study was to identify a potential association between subjective dry eye symptoms, objective dry eye markers, and possible changes in the tear film, which could be a target for future therapy development. Therefore, clinical (dry eye) examinations (OSDI, Schirmer test, lissamine green and fluorescein staining, BUT, visual acuity) were carried out before LASIK as well as 5 and 90 days post-OP. The dry eye marker MMP-9, cytokines (IL-1β, IL-8), and pain markers (NGF, CGRP) were quantified in tear samples with immunoassays. In addition, correlation analyses were performed. Clinical examinations revealed an upregulated OSDI score 5 days post-OP and an increased lissamine green staining score 90 days post-OP. Downregulated CGRP levels were noted 5 days post-OP, while other protein markers were not significantly altered after Femto-LASIK. Hence, Femto-LASIK surgery induced subjective symptoms like that of dry eye which could objectively rather be classified as Femto-LASIK-related discomfort. In the future, this could possibly be better detected and treated using pain markers such as CGRP.

Abstract
Background: To determine efficacy of two lacrimal substitutes on signs and symptoms of ocular surface disease after phacoemulsification; to determine impact of surgery on patients’ vision related quality of life. Monocentric, randomised, physician blinded, three parallel groups clinical trial. Design and Methods: Patients in the operative list for phacoemulsification have been screened for eligibility; they underwent (at time 0, 15, 45 and 90 days): slit lamp examination; tear film break-up time (BUT); corneal staining; tear volume; 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ); Ocular Surface Disease Index (OSDI). Treatments to be compared were: 1. standard of care-SOC (lomefloxacine and tobramicine/dexamethasone fixed combination 4 times a day for 2 weeks), 2. SOC + carboxymethylcellulose sodium 0.5% and glycerin 0.9%, 3. SOC + Sodium Hyaluronate 0.15%. Study treatment started at T15. Groups were compared with parametric or nonparametric tests, and with Pearson’s χ2 test. Correlation between continuous variables was assessed by means of Pearson’s or Spearman’s coefficient. Results: Fifty-three patients were enrolled. At 45 and at 90 days from surgery, the group receiving lacrimal substitutes presented better BUT and Schirmer I test (p = 0.009, <0.001, <0.001 and 0.001, respectively); dry eye presence showed significant difference by group at time 90 (p = 0.019). General vision, near activity and vision-specific dependency subscales improved after surgery (p = <0.001, 0.004 and 0.048, respectively). At 45 and 90 days from surgery, the OSDI score significantly changed (p < 0.001).Conclusions: Cataract surgery causes the onset or the worsening of dry eye. Use of artificial tears can significantly reduce symptoms and signs of dry eye in patients after phacoemulsification.

Abstract
BACKGROUND Septal deviation causes the air entering the nose to encounter resistance and leads to turbulent flow formation by disrupting laminar air flow. In the literature, the Schirmer test has been recommended to evaluate the moistening of the nasal mucosa. AIMS/OBJECTIVES The purpose of this study was to evaluate the degree of nasal humidification using the intranasal schirmer test in patients with septal deviation and to reveal changes in mucosal dryness and humidity in both nasal cavities following septoplasty surgery. MATERIAL AND METHODS Fifty-three patients with septal deviation detected at endoscopic rhinoscopic examination and scheduled for surgery were enrolled. Schirmer test was performed twice, at a one-month interval, pre- and postoperatively and test records were compared. RESULTS The Schirmer test value for the deviated side of the septum was significantly lower than that for the contralateral side, for both nasal cavities. Schirmer test values increased significantly on the side of the septal deviation compared to the preoperative values. CONCLUSIONS AND SIGNIFICANCE Septoplasty surgery performed for septal deviation significantly and reduces nasal mucosa dryness so increases Schirmer test results on the deviated side. We attribute this to septal deviation impairing air flow in the nasal cavity and causing nasal mucosa dryness.

Abstract
Background/Aims: This study aimed to analyze the effects of perinatal history on tear film properties and lid geometry in adults born preterm. Methods: The Gutenberg Prematurity Eye Study (GPES) is a German prospective examination of adults born preterm and term aged 18 to 52 years with Keratograph® 5M and Schirmer test I. Main outcome measures were first non-invasive tear film break-up time (F-NITBUT), bulbar redness (BR), Schirmer test, and nasal palpebral angle measurement. The associations with gestational age (GA), birth weight (BW), and BW percentile, retinopathy of prematurity (ROP), ROP treatment, and other perinatal factors were evaluated using regression analyses. Results: 489 eyes of 255 preterm and 277 eyes of 139 full-term individuals (aged 28.6 +/− 8.8 years, 220 females) were included. Of these, 33 participants (56 eyes) had a history of spontaneously regressed ROP and 9 participants (16 eyes) had a history of ROP treatment. After adjustment for age and sex, lower F-NITBUT (<20 s) was associated with ROP treatment (OR = 4.42; p = 0.025). Lower GA correlated with increased bulbar redness (B = −0.02; p = 0.011) and increased length of wetting in the Schirmer test (B = −0.69; p = 0.003). Furthermore, low GA was associated with narrowing of the nasal palpebral angle (B = 0.22; p = 0.011) adjusted for age and sex, but not when considering ROP in the multivariable model. Conclusion: Our analyses indicate that perinatal history affects ocular surface properties, tear production and lid geometry in adults born term and preterm. This might indicate that affected persons have a predisposition to diseases of the corneal surface such as the dry eye disease.

Abstract
Purpose To compare the repeatability and reproducibility of the Schirmer test (ST) without anesthesia when the eyes are open (STo) and closed (STc) in previously undiagnosed patients with suggestive symptoms of dry eye. Methods In a comparative, observational series case study, 31 patients were included in the study. STo and STc were alternately applied for a total of six times. The ST was applied two times with the eyes open (S1) and closed (S2), respectively, by a single ophthalmologist. Then the ST was repeated four times with the eyes open (S3, S5) and closed (S4, S6), respectively, by a single nurse. Results S1, S3, and S5 were 23.4, 23.7, and 23.3 mm, respectively. S2, S4, and S6 were 14.7, 15.6, and 16.6 mm, respectively. STc scores were found to be statistically lower than the STo’s in general (right: t = 2.033, p = 0.048; left: t = 3.474, p = 0.004). There was no statistically significant difference in the scores of the three tests with open eyes: S1, S3, and S5 (p = 0.462). There was also no statistically significant difference in the scores of the three tests with closed eyes: S2, S4, and S6 (p = 0.05). Conclusions Our study suggests that although administering the ST with the patient’s eyes open produces higher readings than STc in patients with suggestive symptoms of dry eye, there was an acceptable reliability among tests performed open and closed. Moreover, intraexaminer reliability was higher than interexaminer reliability for both with the eyes open and closed.

Abstract
Dry eye disease (DED) has a higher prevalence than many important systemic disorders like cardiovascular disease and diabetes mellitus, representing a significant quality of life burden for the affected patients. It is a common reason for consultation in general eye clinics worldwide. Nowadays, the diagnostic and therapeutic approach at the high corneal and ocular surface specialty level should be reserved for cases of severe and chronic dry eye disease associated with systemic autoimmune diseases or complicated corneal and ocular surface pathologies. In such cases, the diagnostic and therapeutic approach is often complex, elaborate, time-consuming, and costly due to the use of extensive dry eye questionnaires, noninvasive electronic diagnostic equipment, and clinical laboratory and ancillary tests. However, other eye care specialists attend a fair amount of DED cases; therefore, its diagnosis, classification, and management should be simple, practical, achievable, and effective. Considering that many patients attending non-specialized dry eye clinics would benefit from better ophthalmological attention, we decided to elaborate a practical DED classification system based on disease severity to help clinicians discriminate cases needing referral to subspecialty clinics from those they could attend. Additionally, we propose a systematic management approach and general management considerations to improve patients' therapeutic outcomes according to disease severity.

Abstract
Background Dry eye disease (DED) occurs as a result of an abnormality in tear production, tear consistency, and tear evaporation. Aim The aim of this study is to determine the prevalence and risk factors associated with dry eye disease in a population-based setting in Southwest Nigeria. Patient and Methods A cross-sectional study was conducted at a medical outreach at Iperu Remo in Nigeria. A systematic random sampling technique was used to select 415 participants. Symptoms of dry eye were evaluated using the Ocular Surface Disease Index questionnaire. Tear film break-up time (TBUT), fluorescein staining, Schirmer test with anesthesia, and meibomian gland were evaluated. The diagnosis of DED was confirmed when the OSDI score is ≥13 and TBUT is less than 10 seconds. Data were analyzed using descriptive statistics, Chi-square, and logistic regression analyses at a 0.05 level of significance. Results The overall prevalence of DED was 28.2%. Adults aged between 31 and 40 years were 23 times more likely to be diagnosed with dry eyes (aOR = 23.13; 95% CI: 1.32 - 405.99; P = 0.032) compared to those between 16 and 20 years. Female adults were about four times more likely to be diagnosed with dry eyes (aOR = 3.59; 95% CI: 1.44 - 8.94; P = 0.006). The use of drugs was also significantly associated with dry eyes. Conclusion This study shows a fairly high prevalence of DED among adults in a semi-urban area in Southwest Nigeria. Ophthalmologists and other eye care workers need to be cautious about the DED and offer appropriate treatment options to patients.

Abstract
PURPOSE To examine the effects of systemic isotretinoin treatment on the eye using several ocular examination parameters. METHODS We conducted a systemic review for literature published up to June 2021 in both PubMed and Web of Science databases. We included prospective observational or interventional studies evaluating ocular manifestations of isotretinoin in acne patients. The primary outcome measures were anaesthetized and non-anaesthetized Schirmer test, tear break-up time (TBUT), central corneal thickness (CCT), average retinal nerve fibre layer (RNFL) thickness, ganglion cell-inner plexiform layer (GC-IP) thickness, subfoveal choroidal thickness, axial length, ocular surface disease index (OSDI), meibomian gland expression (MGE) and conjunctival stain. The National Institute of Health (NIH) quality assessment tools were used to assess the data quality. The effect size used to analyse the included studies was the weighted mean difference (WMD) and its related confidence intervals (95%CIs). RESULTS Twenty-one publications involving 1105 eyes of 842 participants met the inclusion criteria. Isotretinoin use was significantly associated with reduction in the scores of anaesthetized Schirmer (WMD = -2.23, 95%CI: -3.28 to -1.18), non-anaesthetized Schirmer (WMD = -3.74, 95%CI: -4.23 to -3.25), TBUT (WMD = -3.47, 95%CI: -5.09 to -1.86), and CCT (WMD= -7.39, 95%CI: -13.91 to -0.88). Isotretinoin use was significantly associated with increase of OSDI (WMD = 18.29, 95%CI: 7.54-29.03), MGE (WMD = 1.02, 95%CI: 0.70-1.33) and conjunctival stain scores (WMD = 0.61, 95%CI: 0.47-0.76). No significant change was noted in RNFL thickness (WMD = -0.64, 95%CI: -1.80 to 0.51); GC-IP thickness (WMD = 0.42, 95%CI: -1.08 to 1.92); subfoveal choroidal thickness (WMD = -1.80, 95%CI: -6.69 to 3.09), and axial length (WMD = 0.08, 95%CI: -0.19 to 0.35). A significant heterogeneity was found between the study estimates in each of anaesthetized Schirmer, TBUT, MGE, OSDI, and conjunctival stain tests. CONCLUSION Isotretinoin use results in a statistically significant reduction of the central corneal thickness, TBUT, and Schirmer test scores. A statistically significant increase in MGE, OSDI and conjunctival stain scores was found. No statistically significant change of average RNFL, GC-IP thickness, subfoveal choroidal thickness, or axial length was observed. Further well-designed studies should evaluate the long-term effect of isotretinoin on the eye and reach a firmer conclusion.

Abstract
Background: Ocular surface frequently affects glaucoma patients. In this paper we aimed at evaluating the impact of glaucoma surgery on the ocular surface of patients who received unilateral trabeculectomy. Methods: 26 consecutive patients successfully treated with trabeculectomy on one eye (Trab Eye) and under control with topical treatments on the fellow eye (Med Eye) were included in this observational study. They received IDEEL and OSDI questionnaires, Tear Film Osmolarity (TFO), grading of conjunctival hyperemia, fluorescein tear break-up time (tBUT), grading of corneal staining and Schirmer test. Results: IDEEL and OSDI scores were 48 ± 38 and 11 ± 12, respectively, with moderate correlation (r = 0.50, p = 0.03). Compared with Med eyes, Trab Eyes had higher tBUT (6.5 ± 3.5 vs. 5.1 ± 2.7 s, p = 0.004), lower conjunctival hyperemia (0.8 ± 0.9 and 1.7 ± 1.1 respectively, p < 0.001) and lower corneal staining (0.3 ± 0.5 and 0.6 ± 0.5, respectively, p = 0.03). Correlation between corneal staining and conjunctival hyperemia was 0.55 in Trab Eyes (p = 0.01) and 0.44 in Med Eyes (p > 0.05). Patients with bilateral corneal staining had had threefold worse questionnaire scores (p < 0.05). The duration of treatment and the daily exposure to preservatives did not directly affect OS parameters in this cohort of patients. Conclusions: Patients receiving successful trabeculectomy showed better OS homeostasis (higher TBUT, lower grading of conjunctival hyperemia and corneal staining) than fellow medically treated eyes. Presence of corneal epithelial damage in both eyes is the factor more consistently affecting questionnaire scores.

Abstract
Purpose A study of the association between vitamin D deficiency and dry eye syndrome (DES) in the Indian population. Methods This was a cross-sectional, hospital-based observational study. Sixty patients diagnosed with vitamin D deficiency (<20 ng/dl) who met the inclusion criteria were sent to the Eye OPD from the Endocrinology OPD (case) were compared to 60 subjects with normal vitamin D levels (≥20 ng/dl) who attended the Eye OPD (controls). The examination of the tear film was done using Whatman filter paper in Schirmer test I and Schirmer test I (with anesthesia). The tear film break-up time (TFBUT) was determined by slit-lamp examination using the fluorescein stain, and scoring using the ocular surface disease index (OSDI) was done. Results A significant difference in the mean values of Schirmer I and Schirmer I test (with anesthesia) (P < 0.001) was seen between the case and control groups. A significant difference in the mean values of TFBUT (P < 0.001) and OSDI scores (P < 0.01) was also seen between the two groups. Conclusion A positive association was found between vitamin D deficiency and dry eye on comparing the above parameters.

Abstract
Over the last two decades, a large number of non-communicable/chronic disorders reached an epidemic level on a global scale such as diabetes mellitus type 2, cardio-vascular disease, several types of malignancies, neurological and eye pathologies-all exerted system's enormous socio-economic burden to primary, secondary, and tertiary healthcare. The paradigm change from reactive to predictive, preventive, and personalized medicine (3PM/PPPM) has been declared as an essential transformation of the overall healthcare approach to benefit the patient and society at large. To this end, specific biomarker panels are instrumental for a cost-effective predictive approach of individualized prevention and treatments tailored to the person. The source of biomarkers is crucial for specificity and reliability of diagnostic tests and treatment targets. Furthermore, any diagnostic approach preferentially should be noninvasive to increase availability of the biomaterial, and to decrease risks of potential complications as well as concomitant costs. These requirements are clearly fulfilled by tear fluid, which represents a precious source of biomarker panels. The well-justified principle of a "sick eye in a sick body" makes comprehensive tear fluid biomarker profiling highly relevant not only for diagnostics of eye pathologies but also for prediction, prognosis, and treatment monitoring of systemic diseases. One prominent example is the Sicca syndrome linked to a cascade of severe complications that include dry eye, neurologic, and oncologic diseases. In this review, protein profiles in tear fluid are highlighted and corresponding biomarkers are exemplified for several relevant pathologies, including dry eye disease, diabetic retinopathy, cancers, and neurological disorders. Corresponding analytical approaches such as sample pre-processing, differential proteomics, electrophoretic techniques, high-performance liquid chromatography (HPLC), enzyme-linked immuno-sorbent assay (ELISA), microarrays, and mass spectrometry (MS) methodology are detailed. Consequently, we proposed the overall strategies based on the tear fluid biomarkers application for 3P medicine practice. In the context of 3P medicine, tear fluid analytical pathways are considered to predict disease development, to target preventive measures, and to create treatment algorithms tailored to individual patient profiles.

Abstract
PURPOSE To assess the severity of dry eye disease in patients with blepharospasm (BEB) before (control) and after injection of botulinum neurotoxin A (BoNT/A). DESIGN Cross-sectional study. METHODS Patients with clinically diagnosed BEB and no known history of dry eye syndrome prior to the onset of the disease, before (controls) or after injection with one of the three available types of BoNT/A: onabotulinumtoxinA (Botox®; Allergan, Irvine, CA, USA), abobotulinumtoxinA (Dysport®; Beaufour Ipsen Pharma SAS, Paris, France) or incobotulinumtoxinA (Xeomin®; Merz Pharma GmbH, Frankfurt, Germany) every 3 months. Tear osmolarity and Schirmer's I-test were measured at the first visit for non-treated BEB patients as controls and 3 months after BoNT/A injection. RESULTS The study consisted of 101 BEB patients (86 females, 15 males) with a mean age of 67 years (range 30-86 years). Seventeen patients were untreated, 26 treated with onabotulinumtoxinA, 23 treated with abobotulinumtoxinA and 35 treated with incobotulinumtoxinA. Post-injection mean tear osmolarity was not significantly higher among patients treated with onabotulinumtoxinA, abobotulinumtoxinA, or incobotulinumtoxinA (P=0.65, P=0.92, and P=0.15, respectively), compared to controls, remaining less than 308 mosm/mL. Mean Schirmer's I-test results remained under 5mm and did not vary between the four groups. CONCLUSIONS The results clearly demonstrate that reduced tear secretion appears to be present in BEB patients even prior to treatment. This decreased lacrimal secretion was not correlated with hyperosmolarity. Clinicians should proactively treat dry eye syndrome in conjunction with management of the blepharospasm.

Abstract
PURPOSE To evaluate conjunctival impression cytology (CIC) findings and tear film parameters in patients with multiple sclerosis (MS) compared with controls. METHODS Thirty-three patients with MS (MS group) and 33 age- and sex-matched healthy subjects (control group) were included in this cross-sectional comparative study. CIC grades, tear break-up time (TBUT), Schirmer 1 test results, and Ocular Surface Disease Index (OSDI) scores were compared between the two groups, and correlations between CIC grade, TBUT, Schirmer 1 test result, OSDI score, Expanded Disability Status Scale score, and disease duration were analyzed. RESULTS Mean CIC grade was higher in the MS group than in the control group (1.48 ± 0.71 and 0.39 ± 0.56, respectively; p < 0.001). In the MS group, CIC of the 14 participants (42.4%) was grade 2-3. In the control group, CIC of the only one participant (3.3%) was grade 2, and none of them was grade 3. TBUT (8.12 ± 3.16, 13.06 ± 4.23 s in MS and control groups, respectively; p < 0.001) and Schirmer 1 test results (8.45 ± 5.75, 17.36 ± 10.89 mm in MS and control groups, respectively; p < 0.001) were lower, and OSDI score (36.36 ± 19.19, 13.70 ± 15.36 in MS and control groups, respectively; p < 0.001) was higher in the MS group compared to the control group. CONCLUSION In patients with MS, objective findings of dry eye, subjective symptoms related to dry eye, and CIC abnormalities, including high grades of conjunctival squamous metaplasia and goblet cell loss, are more common. Patients with MS should be monitored for ocular surface alterations and dry eye disease.

Abstract
Purpose: To evaluate whether dry eye deteriorates after phacoemulsification cataract surgery, and to explore the influential factors. Methods: Studies published before February 2020 indexed on PubMed and the Cochrane Central Register of Controlled Trials were retrieved. A meta-analysis, including meta-regression, a sensitivity analysis, and a subgroup analysis, were performed. Results: Twenty studies with 2,247 eyes were included in the meta-analysis, dry eye-related parameters were investigated preoperatively and 1 month postoperatively. Patients with pre-existing meibomian gland dysfunction (MGD) had worsened subjective symptoms of dry eye (1.31, 95% confidence interval (CI) [0.66, 1.95], P < 0.0001), a reduced tear break-up time (BUT) (−2.27, 95% CI [−2.66, −1.88], P < 0.0001), and a worse corneal fluorescein staining (CFS) score (0.75, 95% CI [0.5, 1.0], P < 0.0001) after phacoemulsification cataract surgery, whereas in the general population, the subjective symptoms score and CFS remained unchanged and BUT decreased slightly after surgery. Patients without diabetes showed significantly reduced total tear secretion after phacoemulsification cataract surgery (−1.25, 95% CI [−1.62, −0.88], P < 0.0001). Conclusion: Dry eye generally remained unchanged 1 month after phacoemulsification cataract surgery. Notably, worsened symptoms and signs of dry eye were observed more frequently in patients with pre-existing MGD. Patients without diabetes were more susceptible to reduced tearing postoperatively.

Abstract
Objectives: To evaluate the frequency and findings of dry eye associated with ocular graft-versus-host disease (GVHD) in pediatric hematopoietic stem cell transplantation (HSCT) patients. Materials and Methods: Retrospectively the records of pediatric patients with ocular GVHD were evaluated and ophthalmologic examination findings as well as Schirmer test results, tear film break-up time, and corneal staining grades were recorded. In severe dry eye patients topical cyclosporine-A was prescribed and the results were evaluated. Results: GVHD was detected in 51 (23.4%) of 218 HSCT patients, 4 of whom died during follow-up. Thirty (63.8%) of the remaining 47 patients had chronic ocular GVHD and 4 patients with severe dry eye were treated with topical cyclosporine-A with a median follow-up of 12.1 months. Severe dry eye symptoms and findings significantly improved in 2 patients. However, 1 patient had to stop treatment due to side effects. Conclusion: In children, chronic ocular GVHD is a common finding of GVHD after HSCT. Therefore, these patients should be examined periodically for dry eye.

Abstract
Objective To compare bleb morphology and tear tests of glaucoma patients who used trehalose and those who did not use after primary trabeculectomy with mitomycin C (MMC) during the early post-operative period. Methods This retrospective study included two groups: Group 1 using Trehalose + hyaluronic acid (THA) after primary trabeculectomy with MMC (n = 19) and Group 2 undergoing primary trabeculectomy with MMC (n = 16). The preoperative and postoperative intraocular pressure (IOP), the results of Schirmer, and tear break-up time tests were analyzed. Postoperative bleb morphology was also evaluated at the 1st day, and 1st and 2nd weeks, and 1st and 2nd months. Results There was no statistically significant difference in preoperative IOP, Schirmer test or tear break-up time between groups. The mean horizontal extent of the blebs was significantly wider in Group 1 at the first week (p= 0.02). Bleb vascularization was also found to be lower in Group 1 at the second week (p= 0.001). The mean bleb height and horizontal extent were significantly higher in Group 1 at the first month (p=0.02, p= 0.03, respectively). The mean bleb horizontal extent was significantly higher in Group 1 at the second month (p= 0.03). Conclusion The use of trehalose improved surgical success of primary trabeculectomy with MMC in terms of IOP control, post-operative complications, and bleb morphology during the early postoperative period. Trehalose might contribute to wound healing which led to an ideal bleb.

Abstract
BACKGROUND Dry eyes are common in the general population. Some studies associate high prevalence of dry eyes with lipid metabolic changes and body fat composition. AIM To study the association of dry eye with percentage of body fat. METHODS One hundred and thirty five individuals (44 males and 91 females; median age of 42 years) were studied in a cross-sectional prospective study. Schirmer test and TBUT (tear breakup time) test were used to access dry eye. Body composition (percentage of lean and fat mass) were calculated using anthropometric measurements that included height, weight, abdominal, waist and neck circumference. RESULTS About 44.4% of the sample had abnormal Schirmer test, and 70.3% had abnormal TBUT. Schirmer tests values were associated with age (p = 0.0006) female gender (p = 0.04) and percentage of body fat (p = 0.02). Abnormal TBUT test associated only with age (p = 0.0005). CONCLUSIONS Percentage of body fat is associated with abnormal Schirmer but not TBUT test.

Abstract
Aim: To compare the outcomes of non-invasive break-up time (NI-BUT) test and the other conventional dry eye tests.Methods: The right eyes of 170 subjects were included in the study. In order to evaluate the tear quality of the patients, NI-BUT levels were measured by the Scheimplug-Placido disk system (Sirius topography). Tear osmolarity test was performed with TearLab Osmolarity System. Topical anesthesia-assisted type I Schirmer test and topical anesthesia-assisted BUT were lastly applied to all patients in order not to affect other measurements.Results: The mean NI-BUT value was 9.59 ± 4.37 sec, tear osmolarity was 292.93 ± 9.30 mOsm/L, Schirmer test was 15.32 ± 6.05 mm/5 min, and biomicroscopic BUT value was 8.98 ± 3.79 sec. The Schirmer test results were statistically significantly correlated with biomicroscopic BUT and NI-BUT values (p = .019, r = 0.180 and p = .030, r = 0.166; respectively). It was also found that tear osmolarity was strongly and inversely correlated with biomicroscopic BUT and topographic NI-BUT values (p < .001, r = -0.554 and p < .001, r = -0.528; respectively). There was no significant correlation between Schirmer test and tear osmolarity.Conclusion: It is important to use a sensitive, reproducible and non-invasive method in the evaluation of tear functions. We think that the objective and noninvasive topographic NI-BUT measurements and the minimally invasive osmolarity measurements should be used more frequently in practice because they are correlated with the measurements obtained by invasive methods and should be widespread in clinics.

Abstract
PURPOSE To evaluate the effects of current ocular surface disease (OSD) on OCT signal quality and peripapillary retinal nerve fiber layer (RNFL) thickness measurements in patients treated with antiglaucomatous medications and the changes in these test results by dry eye treatment. METHODS Fifty-five patients, diagnosed with primary open-angle glaucoma (POAG) and OSD, who were treated for glaucoma with topical medications for at least 6 months were included in this study. Patients were treated with topical preservative free polyvinyl alcohol + povidone artificial tear drops four times a day for at least 20 days and topical loteprednol etabonate drops four times a day for 1 week. Patients were divided into groups according to the number of active substances in their glaucoma drops, daily drop numbers, and duration of drug utilizations. OCT signal quality and mean RNFL thickness measurements were evaluated within these groups before and after OSD treatment. RESULTS Pre-treatment mean OCT signal quality was 19.15 ± 3.739 and mean RNFL thickness was 93.07 ± 13.931µ; post-treatment mean OCT signal quality was 23.93 ± 3.839 and mean RNFL thickness was 98.27 ± 14.863 µ (p < 0.05). Post-treatment measurements were significantly improved compared to pre-treatment measurements in our patients, but the differences among subgroups were not statistically significant. There was a strong positive correlation between pre-treatment signal quality measurements and Schirmer II test values (p < 0.0001). CONCLUSION Treatment of OSD in glaucoma patients being treated with long-term anti-glaucoma medications, seem to improve the quality and reliability of OCT test results.

Abstract
Introduction Oral and ocular dryness are the most common symptoms reported during ophthalmological and dental examinations. It is becoming a serious and growing problem due to the huge variety of affecting factors and with population aging. Objectives The purpose was to demonstrate an application of the Schirmer test for xerostomia. Subsequently, to compare and correlate the results achieved from the lacrimal Schirmer test and salivary Schirmer test in non-Sjögren patients. Methods Study group consisted of 642 patients with/without subjective or/and objective symptoms of dry eye or mouth who did not fulfill the criteria for diagnosis of Sjögren syndrome. The lacrimal Schirmer test (lST) and the salivary Schirmer tests (sST) were performed (sSTm was put on the floor of the mouth, sSTp in front of the parotid gland duct). The results were recorded after 1 min (sSTm), 3 min (sSTp), and 5 min (lST). Results The lST and sST test scores were considerably higher in the healthy group than in others, p < 0.001. The results of sST1 and sST2 decreased with the appearance of subjective and objective symptoms, p < 0.001. There were positive correlations between lST and sSTm outcomes between the groups, p < 0.001. Conclusions We present the Schirmer test adapted to measure salivary gland hypofunction that is a time-saving tool in our daily practice. Results of this study reveal an excellent correlation between the eye Schirmer test and the salivary Schirmer tests. Clinical relevance The salivary Schirmer tests seem to be rapid, convenient, and reliable objective screening tools for salivary gland hypofunction in non-Sjögren patients.

Abstract
OBJECTIVE This study aimed to determine the relationship between clinical symptoms and findings of patients diagnosed with conjunctivochalasis in our clinic and the risk factors reported in the literature, to determine new possible etiological factors, and to compare routine tear assessment methods with novel strip meniscometry in these patients. MATERIALS AND METHODS The study included patients who presented to our clinic between March 2019 and June 2019 and were diagnosed with conjunctivochalasis. The Ocular Surface Disease Index was used to assess ocular surface symptoms. Anterior segment examination included tear break-up time, corneal staining, localization of conjunctivochalasis, and the presence of pinguecula or pterygium. For each patient, tears were measured using both Schirmer and strip meniscometry. Patients with conjunctivochalasis were evaluated as lid-parallel conjunctival folds grade 1, 2, or 3. RESULTS There was a total of 57 participants, including 31 women (54.4%) and 26 men (45.6%). Lid-parallel conjunctival folds grade was found to be statistically significantly associated with dust exposure (p = 0.034). Multiple regression analysis revealed that dust exposure was an independent predictor of being diagnosed with lid-parallel conjunctival folds grade 2 versus lid-parallel conjunctival folds grade 1 (odds ratio = 3.515, p = 0.029). Moreover, Schirmer's test and strip meniscometry results were positively correlated in patients with conjunctivochalasis (r = 0.302 and p = 0.022). CONCLUSION We conclude that external factors are prominent in patients with conjunctivochalasis, especially dust exposure. In addition, strip meniscometry may be preferred as a more practical and noninvasive alternative to investigate dry eye symptoms in patients with conjunctivochalasis.

Abstract
Purpose The aim of this study was to investigate the association of dry eye disease (DED)-related signs and symptoms with two tear function tests. Methods This was a clinic-based, cross-sectional study with recruitment of consecutive participants. Schirmer test (ST), tear strip meniscometry (SM), and fluorescein tear breakup time were measured and corneal staining score was examined in outpatients at three clinics. Seven subjective symptoms were assessed by interview, including dryness, irritation, pain, lacrimation, fatigue, blurring, and photophobia. Statistical analyses included regression analysis and comparison tests. Results The mean age of the 210 participants was 61.2 ± 15.2 years (range, 12-91 years), with 135 women (64.3%) in the cohort. The mean ST value was 12.9 ± 9.3 (0-35) mm, and SM was 2.5 ± 1.6 (0-10) mm, with no difference between women and men. SM values were lower in the presence of irritation (P = 0.046) and photophobia (P = 0.011). Regression analysis revealed ST and SM values were strongly correlated (β = 0.255, P < 0.001). SM was significantly correlated with breakup time (β = 0.149, P = 0.032), whereas there was no correlation between ST and DED-related signs and symptoms. Conclusions SM was correlated with DED-related symptoms and breakup time, whereas ST was not. A low SM value could be an alternative clinical parameter to determine tear film-oriented therapy. Translational Relevance Tear strip meniscometry could be a useful tear function examination on a routine clinical basis since it is a 5-second noninvasive procedure and associated with subjective symptoms and the value of the conventional Schirmer test.

Abstract
Background: In systemic sclerosis (SSc) patients, dry eye syndrome (DES) is the most frequent ocular feature. The aim of this study was to investigate ocular DES-related SSc patients and to establish any correlation with the severity of the disease. Methods: Retrospectively, data from 60 patients with SSc underwent ophthalmic examination, where non-invasive film tear break-up time (NIF-TBUT), tear film lipid layer thickness (LLT), anesthetic-free Schirmer test I, tear osmolarity measurement (TearLab System), and modified Rodnan skin score (mRSS) data were collected. The visual analog scale (VAS) and Symptom Assessment in Dry Eye (SANDE) methods were utilized. The results were correlated with mRSS and the duration of SSc. Results: Severe DES occurred in 84% of cases, and was more severe in women. The eyelids were involved in 86.6%, secondary to meibomian gland disease (MGD). A direct correlation was found between the tear osmolarity (mean 328.51 ± 23.8 SD) and skin score (mRSS) (r = 0.79; p < 0.01). Significantly reduced NIF-TBUT, LLT, and Schirmer test I values were observed in the case of severe skin involvement. Conclusions: SSc patients show lipid tear dysfunction related to the severity and duration of the disease due to inflammation and the subsequent atrophy of the meibomian glands.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of preoperative dry eye disease and evaluate tear film function in refractive surgery candidates in China. METHODS In this prospective noninterventional cross-sectional study, refractive surgical candidates from 13 preselected eye hospitals in China were recruited from July 2015 to February 2016. Patient histories, subjective symptoms, tear film breakup time (TBUT), ocular surface fluorescein staining, and Schirmer I tests (SIT), were assessed to conduct subgroup analysis. RESULTS A total of 1,849 patients were recruited, 41.4% were diagnosed with dry eye disease (766/1,849) and 44.9% (830/1,849) of subjects had a positive history of contact lens (CL) wear. The overall mean TBUT and SIT values were 7.3 ± 3.7 s and 15.2 ± 8.8 mm, respectively. The total prevalence of ocular surface fluorescein staining was 23.46% (422/1,849); 44.62% of patients had TBUT <5 s and 23.20% of patients had SIT <5 mm. CL wearers were observed to have a higher prevalence of dry eye than non-CL wearers (54.1 vs. 35.2%, OR = 2.17, 95% CI: 1.77-2.65). CONCLUSIONS In this study, the most common abnormal finding in dry eye disease was tear film instability. A high proportion of refractive surgery candidates have preexisting dry eye disease and a history of CL wear prior to surgery. Careful attention should be given to the evaluation of preoperative dry eye in refractive surgery candidates.

Abstract
Objective: Dry eye is reported to be associated with several neurological diseases. The aim of this study is to evaluate the patients with hemiplegia after stroke for dry eye and compare their results with a control group.Materials and methods: Forty-five patients with hemiplegia and 45 individuals as the control group were included in the study. Tear function tests (Schirmer and tear breakup time) and a dry eye questionnaire for dry eye symptoms (ocular surface disease index) were performed and the results of the two groups were compared.Results: Schirmer test results were significantly lower in the post-stroke hemiplegia group compared to the control group (11.3 ± 8.2 mm and 20.6 ± 11.6 mm, respectively, p < .001). Tear breakup time results were significantly lower in the post-stroke hemiplegia group compared to the control group (7.9 ± 3.1 s and 12.1 ± 4.3 s, respectively, p < .001). Ocular surface disease index scores were not significantly different between hemiplegia and control groups (21.6 ± 20.0 and 19.8 ± 13.9, respectively, p = .635). Schirmer scores lower than 10 mm (60% and 30%, p < .001) and tear breakup time results lower than 10 s (65.6% and 28.9%, p < .001) were also higher in the hemiplegia group compared to control group.Conclusion: We found lower Schirmer test and tear breakup time results and similar OSDI scores in hemiplegia patients compared to controls. Hemiplegia patients may have dry eye without typical symptoms. This should be taken into consideration in the follow-up and rehabilitation of post-stroke hemiplegia patients.

Abstract
PURPOSE Aromatase inhibitors (anastrozole, letrozole) and selective estrogen receptor modulators (tamoxifen) are widely used as adjuvant hormonal therapy in women with hormone receptor-positive breast cancer. We aimed to evaluate the effects of oral adjuvant hormonotherapy on tear functions in patients with breast cancer. METHODS In this case-control study, we enrolled eligible patients with breast cancer who were receiving regular medical selective estrogen receptor modulator (tamoxifen, n:50), aromatase inhibitors (anastrozole, letrozole, n:50) and gender-matched healthy controls (n:50). Tear functions were measured and compared by the Schirmer test, fluorescein breakup time, corneal staining evaluated by Oxford grading scale and Ocular Surface Disease Index scores. RESULTS Mean age was 49.95 (± 9.2), 51.52 (± 7.2) and 51.91 (± 10.3) in tamoxifen, aromatase inhibitors groups and controls (p = 0.426). Mean duration of BC diagnosis (p = 0.536) and drug use (p = 0.417) was not significant between two groups. Ocular Surface Disease Index scores were lower (p < 0.001), and fluorescein breakup time measurements were higher (p < 0.001) in controls. Schirmer test scores were higher in controls than aromatase inhibitors group (p < 0.001). According to the scores of all measurements, the differences between aromatase inhibitors and tamoxifen groups were statistically significant (p < 0.001). CONCLUSIONS Our results demonstrated a high difference in all parameters in patients receiving aromatase inhibitors compared to tamoxifen group and controls. Aromatase inhibitors, which reduce estrogen levels in the blood, might affect the tear functions more than tamoxifen, which affects as antiestrogenic on estrogen receptors.

Abstract
PURPOSE To construct normalized ocular surface temperature (NOST) models for different tear film characteristics and evaluate its potential in dry-eyes screening. METHODS We included 227 right eyes of 227 patients. Tear film characteristics were categorized into 4 types according to fluorescein tear film breakup time (FTBUT) and Schirmer test results, namely type 1: FTBUT >5 s and Schirmer >5 mm; type 2: FTBUT ≤5 s and Schirmer >5 mm; type 3: FTBUT ≤5 s and Schirmer ≤5 mm; and type4: FTBUT >5 s and Schirmer ≤5 mm. Ocular surface temperature was measured by a video-thermographer. Mean temperatures of the central cornea were calculated from the videos of each frame during the 4-s blink interval. We first constructed individual NOST model for every tear characteristic. Participants were included for further analysis when their OSDI was ≥23, FTBUT ≤5 s, and Schirmer >5 mm. They were subdivided into short-BUT and short BUT with SPK subgroups according to the absence or presence of corneal fluorescein-stain. The NOST models of the normal, short-BUT and short BUT with SPK groups were separately constructed and the potential of screening analyzed via ROC curves. RESULTS Each tear film type had a different NOST model. At 3 s after blinking, the order of NOST was type 4 >type 1 >type 3 >type 2. In dry-eye screening, the NOST was normal > short-BUT > short BUT with SPK. The NOST displayed a sensitivity 0.87, specificity 0.80, and AUC 0.88 for diagnosing short BUT with SPK. CONCLUSION NOST models are useful in differentiating tear film characteristics and screening dry-eyes. It alleviates the discomfort and inconvenience encountered during conventional dry-eye diagnosis.

Abstract
PURPOSE To evaluate conjunctival surface cells and tear-film functions in cases with vitamin D deficiency. METHODS Thirty-six patients with serum vitamin D deficiency and 27 control subjects with normal serum vitamin D levels were included in this prospective study. The tear break-up time (TBUT), Schirmer II test, and conjunctival impression cytology tests were performed to all participants. RESULTS The mean serum vitamin D levels were 10.5 ± 5.0 µl in the study group and 33.9 ± 11.7 µl in the control group (p < 0.001). The median TBUT scores were 11 s and 17 s and the median Schirmer II values were 7.5 mm and 12 mm in the study and the control groups, respectively (p = 0.003, p = 0.049). According to the Nelson staging system, 69.4% of the patients in the study group had grade 2 or 3 impression cytology, whereas 18.5% of the participants in the control group had grade 2 or 3 impression cytology (p < 0.001). CONCLUSION Our study results showed that vitamin D deficiency may lead to dry eye causing conjunctival squamous metaplasia and loss of goblet cells on the ocular surface.

Abstract
OBJECTIVE Allergic rhinitis is a type 1 hypersensitivity reaction of immunoglobulin E in the rhino-ocular mucosa. This study was planned to demonstrate in patients with allergic rhinitis to evaluate changes in tear, nasal secretions, and blood osmolarity compared to healthy individuals. METHOD Forty allergic rhinitis patients, 25 patients with acute upper respiratory tract infections, and 26 healthy participants were included in the study. Positive patients with allergic symptoms and skin prick test results were included in the allergic rhinitis group. Tear, nasal secretion, and blood osmolarity values were examined for the 3 groups. RESULT In patients with allergic rhinitis, tear and nasal secretion osmolarity values were significantly higher in patients with acute upper respiratory tract infections and those of the healthy participants (P = .001, P = .038). In blood osmolarity measurements, there was no statistical difference between the groups (P = .489). In patients with allergic rhinitis, Schirmer test results were significantly shorter than patients who had acute upper respiratory tract infection and those of the healthy participants (P = .001, P = .001). Patients with allergic rhinitis and acute upper respiratory tract infections had significantly shorter Schirmer test results than in healthy participants (P = .001, P = .001). CONCLUSION Tear osmolarity was increased in allergic rhinitis patients, and this was thought to lead to dry eye findings. In the presence of allergic rhinitis, nasal secretions were found more hyperosmolar than tears. Nasal secretion osmolarity was higher in allergic rhinitis patients than in patients with acute upper respiratory tract infections and control group.

Abstract
Background Pseudoexfoliative material is being implicated in causing tear film abnormalities, and the aim of the present study was to prove it and to compare with the normal healthy participants. Methods A total of 398 eyes of 200 participants were studied, and two groups were formed. The first, pseudoexfoliation syndrome (PEXS) group, included 198 eyes of 100 patients, and the second, age-matched control group, included 200 eyes of 100 participants. Tear film abnormalities were compared in the two groups by tear meniscus height (TMH), Schirmer test I, Schirmer test II and tear film break-up time (TBUT). Results On comparing the two groups using independent t-test, a significant difference was found in Schirmer test I, Schirmer test II, and TBUT between the PEXS group (Schirmer test I: 23.98 ± 10.68 mm, Schirmer test II: 17.11 ± 8.78 mm, and TBUT: 9.778 ± 5.54 s) and the age-matched control group (Schirmer test I: 27.08 ± 9.58 mm, Schirmer test II: 19.98 ± 8.48 mm, and TBUT: 13.495 ± 5.65 s) (p = 0.003 [Schirmer test I]; p = 0.001 [Schirmer test II]; and p < 0.001 [TBUT]). However, an insignificant difference was found in terms of TMH (p = 0.195) between the two groups. Conclusion PEXS affects tear production and leads to unstable tear film.

Abstract
PURPOSE A review of ocular surface and meta-analysis of tear stability (tear break up time, TBUT) and tear secretion (Schirmer test) values in healthy children was conducted. METHODS Articles published between 1996 and 2017 indexed on MEDLINE, PubMed, Embase, Scopus and Google Scholar were retrieved using defined search terms. Statistical analysis (including sensitivity analysis and meta-regression) was performed. RESULTS 23 studies were summarised (5,291 participants; neonates (0-29 days), infants (1 month - 1 year) or children (1-18 years) and a meta-analysis conducted using 15 eligible studies (1,077 participants). The combined mean TBUT in children was 14.64 seconds (s) (95% CI, 11.64, 17.64) and 21.76 s (95% CI, 20.43, 23.09) for sodium fluorescein TBUT and non-invasive TBUT respectively (NIBUT). The combined mean NIBUT was 32.5 s (95% CI, 31.78-33.22) in neonates. The combined mean Schirmer I with and without anesthesia were 16.26 mm/5 min (95% CI, 13.17, 19.36) and 29.30 mm/5 min (95% CI, 27.65, 30.96) in children and 9.36 mm/5 min (95% CI, 6.54, 12.18) and 17.63 mm/5 min (95% CI, 12.03, 23.23) in neonates. Meta-regression showed a significantly lower TBUT in children from studies conducted in Asia (p = 0.004). CONCLUSION There is paucity of data on ocular surface variables in healthy children, making it difficult to draw valid comparisons with adult values.

Abstract
PURPOSE To investigate the relationship between tear concentration of the homeostatic protein clusterin (CLU) and dry eye signs and symptoms, and to characterize tear CLU protein. METHODS Two independent studies were conducted, one in Tucson (44 subjects), the other in Los Angeles (52 subjects). A cohort study design was employed to enroll patients without regard to dry eye diagnosis. Dry eye signs and symptoms were assessed using clinical tests. Tear samples were collected by Schirmer strip, and also by micropipette at slit lamp when possible. CLU from both sample types was quantified by immunoassay. The relationship between CLU concentration and clinical test scores was determined by Pearson's correlation coefficient (for individual eyes) and multiple linear regression analysis (including both eyes). CLU was also evaluated biochemically by western blotting. RESULTS In the Tucson cohort, a positive correlation was observed between tear CLU concentration and results of the Schirmer strip test, a measure of tear flow (p = 0.021 includes both eyes). This result was corroborated in the Los Angeles cohort (p = 0.013). The mean tear CLU concentration was 31 ± 14 μg/mL (n = 18 subjects, 33 eyes; range = 7-48 μg/mL). CLU from clinical tear samples appeared biochemically similar to CLU from a non-clinical tear sample and from blood plasma. CONCLUSIONS Results support the hypothesis that an optimal concentration of tear CLU is important for ocular surface health, and that this drops below the effective threshold in dry eye. Tear CLU measurement might identify patients that could benefit from supplementation. Information about concentration will aid development of therapeutic dosage parameters.

Abstract
Purpose Reliable measurement of MUC5AC in human tears is essential for elucidation of the pathophysiological role of MUC5AC in dry eye disease. The purpose of this study was to develop a sensitive and reliable method for measurement of MUC5AC in human tear samples extracted from Schirmer strips by modifying a commercially available ELISA. Methods MUC5AC was extracted from Schirmer strips containing human tears by PBS with various concentrations of polysorbate 20. The extracts were treated with neuraminidase A to cleave the sialic acids in MUC5AC. An ELISA plate was blocked to prevent nonspecific binding. The rate of extraction of MUC5AC from Schirmer strips, linearity of dilution, limit of quantification, calibration range, and intra-assay and inter-assay reproducibility were examined. Results MUC5AC was extracted using polysorbate 20 in a concentration-dependent manner. Extraction was more efficient at 37°C than at 25°C. The signal-to-noise ratio of the assay was dramatically increased by treatment with neuraminidase A. Treatment with a blocking reagent before incubation produced good linearity of dilution. The inter-assay and intra-assay coefficients of variation were ≤16.6%. The relative error was within 13%. Conclusion We developed an efficient method for extraction of MUC5AC from Schirmer strips and a highly sensitive, reliable assay for MUC5AC in human tear samples using a commercially available ELISA kit. This method will aid in our understanding of the pathophysiology of dry eye, assessment of the effects of treatment in daily practice, and selection of appropriate therapeutic agents for patients.

Abstract
OBJECTIVE: To evaluate the effects of long-term computer use on tear production and evaporation. METHODS: In this study, 30 eyes of 30 people using computer for 8 hours a day were taken as the study group. In the control group, 30 eyes of 30 healthy individuals who did not spend 1 hour using computer on a daily basis were evaluated. The cases were examined at 8 am and 5 pm. The Schirmer test, tear break-up time (TBUT), and ocular surface disease index (OSDI) were evaluated. RESULTS: There was no significant difference between the groups in terms of age and gender. The Schirmer test results, which measure the parameters of tear production, were 16.80±2.04 and 15.50±2.06 mm (p>0.05) in the study group, and 17.28±1.52 and 17.16±2.53 in the control group. The TBUT measurements were 9.15±2.93 and 6.80±1.11 sec in the study group. It was observed that the evening TBUT decreased (p<0.05). The TBUT measurements were 15.80±3.15 sec and 15.20±1.92 sec (p>0.05) in the control group. The OSDI scores were 26.7±3.36 and 28.3±1.19 in the study group, and 25.0±4.48 and 27.3±2.27 in the control group. CONCLUSION: As a result, it was found that a long-term computer use did not change the Schirmer test results significantly, but there were statistically significant changes in the tear break-up time (TBUT) results of the evaporative type eye dryness. According the our study results, long-term computer usage may cause an evaporative-type dry eye disease.

Abstract
Purpose To evaluate the association between subjective dry eye symptoms and the results of the clinical examinations. Methods The study was a clinical-based survey involving 215 first-year students selected consecutively during a regular ocular health examination at the University of Cape Coast Optometry Clinic. The data collection process spanned for a period of four months. Out of the 215 students, 212 returned their completed questionnaires and were subsequently included in the study. Dry eye tests including meibomian gland assessment, tear break up time, fluorescein staining, Schirmer test, and blink rate assessment, were performed on each subject after completion of the Ocular Surface Disease Index (OSDI) questionnaire. Shapiro–Wilk test was used to determine the normality of the clinical tests, and Spearman's correlations co-efficient was used to determine the correlations between the clinical test results and dry eye symptoms. Results Statistically significant associations were found between OSDI scores and blink rate (rs = 0.140; P < 0.042), and associations between OSDI scores and contrast sensitivity scores (rs = 0.263; P < 0001). However, the results of corneal staining (rs = −0.006; P < 0.926), Schirmer test (rs = −0.033; P = 0.628), tear break up time (rs = −0.121; P < 0.078), meibomian gland expressibility (rs = 0.093; P < 0.180), and meibomian gland quality (rs = 0.080; P < 0.244) showed no significant association with OSDI. The correlation coefficients range from −0.006 to 0.263 showed low to moderate correlation between dry eye symptoms and the results of clinical test. Conclusion Associations between dry eye symptoms and clinical examinations are low and inconsistent, which may have implications for the diagnoses and treatment of dry eye disease.

Abstract
Pathogenic strains of Acanthamoeba are causative agents of a sight-threatening infection of the cornea known as Acanthamoeba keratitis (AK) which mainly affects contact lens wearers and it is commonly related to poor hygiene of contact lenses and their cases. Moreover, treatment of AK is complex due to the existence of a highly resistant cyst stage and if not diagnosed early has poor prognosis, leading to blindness and/or keratoplasty. Even though AK is increasing worldwide as well as awareness among patients and clinicians, it is still a poorly studied pathogen. Additionally, a remaining question to be answered is whether these opportunistic pathogens are present in the ocular surface of healthy contact lens wearers since they are the main group at risk.In order to carry out this study, sterile Schirmer strip tests were collected from a group of individuals all of them contact lens wearers who were attending a local ophthalmology clinic in Tenerife, Canary Islands, Spain. The collected samples (100 eyes of 50 patients) were cultured in 2% Non-Nutrient Agar (NNA) plates and positive plates (16) were then cultured in axenic conditions for further analyses. Molecular analysis classified all isolated strains belonged to Acanthamoeba genotype T4 and osmotolerance and thermotolerance assays revealed that all strains were potentially pathogenic. In conclusion, the ocular surface of contact lens wearers included in this study was colonized by potentially pathogenic strains of Acanthamoeba and should be considered as a risk for AK infection in this region and worldwide.

Abstract
PURPOSE To study the effects of long-term instillation of 0.18% sodium hyaluronate artificial tears VISMED multi on ocular surface in glaucomatous patients with long-term instillation of preserved anti-glaucoma drops. MATERIAL AND METHODS The study included 79 patients (40 female and 39 male; 79 eyes in total) with primary open-angle glaucoma (POAG) divided into 3 groups according to disease stage: mild or early (stage I) glaucoma - 15 patients (15 eyes), moderate (stage II) glaucoma - 30 patients (30 eyes), advanced or severe (stage III) glaucoma - 34 patients (34 eyes). Conjunctival and corneal changes were assessed with Norn's test, Schirmer I test and corneal fluorescein staining test. All patients completed Ocular Surface Disease Index (OSDI) questionnaire. Corneal compensated intraocular pressure (IOPcc) was measured using Ocular Response Analyzer (ORA) (Reichert Optics Inc., USA). In addition to hypotensive therapy, all patients received instillations of 0.18% sodium hyaluronate (VISMED multi) three times every day. After 14 days, all examinations were repeated. RESULTS The condition of eye surface in patients with moderate and advanced (stage II and III) glaucoma depends on the degree of IOPcc compensation. As glaucoma increases in severity, the pathological changes in the ocular surface progress. Instillations of 0.18% sodium hyaluronate solution lead to significant improvement of the test results in all groups, and in early glaucoma patients it restores all objective indicators to normal values. CONCLUSION Treatment with 0.18% sodium hyaluronate solution (VISMED multi) leads to statistically significant (p<0.05) improvement of ocular surface condition in glaucoma patients with long-term instillation of preserved antiglaucoma eye drops.

Abstract
Objective: To evaluate the short-term changes in Schirmer I test (ST) after pars plana vitrectomy and to compare the results between 23 gauge and 20 gauge vitrectomy surgeries. Methods: 42 patients who underwent pars plana vitrectomy for posterior segment diseases were included in this prospective, non-randomized, comparative study. The choice of sclerotomy gauge was at the surgeons’ discretion. ST values were recorded before and at 1 and 3 months after vitrectomy. Results: 20 patients in 23 gauge and 22 patients in 20-gauge group with a mean age of 59.9 ± 13.5 years were included. The mean preoperative ST values decreased significantly in both groups at 1 and 3 months after surgery (all P < 0.01). The ST values in the fellow eyes were the same, at baseline and during the follow up (P > 0.05). At 3 months visit, 15 eyes (35.7%) had abnormal ST measurements. There was no statistically significant difference in the changes in the ST measurements between the two groups at one month (P = 0.7), however, 3 months after surgery, the mean decrease in the ST measurements was significantly higher in the 20 gauge group (P = 0.03). At 3 months, 4 eyes in the 23 gauge group (20%) and 11 eyes in the 20 gauge group (50%) had abnormal ST measurements (P = 0.05). Conclusions: Although both 20 and 23-gauge vitrectomy decrease the ST measurements postoperatively, the value is less affected by the 23-gauge vitrectomy.

Abstract
OBJECTIVE The aim of this study is to demonstrate the effect of nasal steroid treatment on intraocular pressure and dry eye in allergic rhinitis patients with dry eye. MATERIALS AND METHODS Twenty-nine patients with a diagnosis of allergic rhinitis and dry eye were included. Symptoms and findings of patients before and after nasal steroid therapy were compared. RESULT Ocular Surface Disease Index scores for dry eye symptoms showed significant improvement after nasal steroid treatment (p = 0.003). In the Schirmer test, no significant change was observed in the right or left eye (p = 0.167 and p = 0.489). For the tear film break-up time, no significant change was observed in the right or left eye (p = 0.076 and (p = 0.170). No significant change was observed in the right eye or the left eye in an intraocular pressure test (p = 0.893 and p = 0.495). CONCLUSION In our study, symptoms of dry eye with allergic rhinitis were significantly improved with nasal steroid therapy, without affecting the intraocular pressure.

Abstract
PURPOSE To evaluate and compare three tear sampling methods using two grading scales for administering the tear ferning test (TFT) to healthy dogs. METHODS In total, 90 dogs (180 eyes) were subjected to tear sampling using millimetered strips, reused after the Schirmer tear test (STT) (Schirmer group, SG). Then, the dogs were subdivided into three groups according to sampling approach: micropipette (MPG), microcapillary (MCG), and Schirmer sample 2 (S2G). The collected tears were dried on a clean microscope glass slide at room temperature and humidity. The ferning patterns were observed under a polarized light microscope and classified according to the Rolando and Masmali grading scales. RESULTS Although all three methods were feasible, the STT was easier to perform in clinical settings. Type I and Grade 1 were the most commonly observed (64.17% and 61.7%, respectively) regardless of collection method. There was no significant difference between the STT median values and the TFT classifications. CONCLUSIONS The TFT is appropriate for dogs and can be performed using the three suggested sampling methods, with a higher frequency of Type I and Grade 1. Thus, it is possible to use both grading scales in the classification of tear ferning in dogs.

Abstract
PURPOSE The aim of this study was to evaluate tear osmolarity and tear film function and ocular surface changes in patients with metabolic syndrome. METHODS 108 eyes of 64 patients with metabolic syndrome (group 1) and 110 eyes of 55 healthy individuals (group 2) were included in this cross-sectional study. All participants were evaluated using the Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT), and tear osmolarity. Main outcome measures were Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT), and tear osmolarity values. RESULTS Tear osmolarity values and OSDI scores were significantly higher in group 1 (314.4 ± 19.1 mOsm and 38.9 ± 1.1, respectively) compared with group 2 (295 ± 14.3 mOsm and 18.69 ± 17.2, respectively) (p = 0.01 for both). The Schirmer test values and TBUT in group 1 (10 ± 3.7 mm and 14.8 ± 3.6 sec, respectively) were significantly lower compared with group 2 (16.8 ± 2.6 mm and 18.1 ± 0.5 sec, respectively) (p < 0.001 for both). There was significant correlation between tear osmolarity versus waist circumference and fasting blood glucose in the study group (r = 0.364, p = 0.04; and r = 0.542, p ≤ 0.001, respectively). CONCLUSIONS This study showed that metabolic syndrome can influence tear osmolarity and tear film function. Patients with metabolic syndrome showed tear hyperosmolarity and tear film dysfunction.

Abstract
INTRODUCTION With an incidence rate of 9%, dry eye is a common problem of the ocular surface, especially in patients more than 40-year-old. Green tea extract has anti-oxidative, anti-bacterial, anti-androgen, and immunomodulatory properties. AIM To evaluate the efficacy of green tea extract for treatment of patients with dry eye and Meibomian Gland Dysfunction (MGD). MATERIALS AND METHODS In a double-blind randomized controlled clinical trial, 60 patients were selected within the age range of 30 to 70 years, and divided into two groups by blocked randomization method. Standard treatment included artificial tear eye drops, three times a day for a month for all patients. Topical green tea extract was prescribed three times a day for one month in one of the groups. All patients were evaluated at the beginning and end of the study for clinical symptoms based on the Ocular Surface Disease Index (OSDI) score, Schirmer's test, Tear Breakup Time (TBUT), corneal and conjunctival staining and meibum score. RESULTS The mean age of participants in the green tea and control group was 61 and 64 years respectively. In the green tea group, the mean score of clinical symptoms was 9±0.86 that improved to 4.86±0.55 after one month (p=0.002). Scores suggesting improvement of TBUTs and the health of meibomian glands were significantly higher in the green tea group (p=0.002). Furthermore, no side effects of the treatment were observed. CONCLUSION Green tea extract is an effective, safe, and well-tolerated topical treatment for mild and moderate evaporative dry eyes and MGD.

Abstract
OBJECTIVE The aim of the present study is to evaluate the effect of ginger herbal spray on reducing dry mouth in patients with Type II diabetes. MATERIALS AND METHODS This clinical trial was conducted on 20 patients with Type II diabetes suffering from dry mouth. The control individual for each patient was the same patient himself/herself. Each patient filled out his/her questionnaire at three different times, (before treatment, after treatment with placebo, and after taking the drug). Furthermore, the Schirmer test was performed to measure the flow of saliva in the patients. The drug and the placebo were prepared as oral sprays containing herbal extracts of ginger. RESULTS The mean amount of saliva after using the ginger plant spray increased significantly (p<0.001). The mean amount of saliva after treatment with medication was considerably different from the mean amount of saliva after treatment with the placebo (p<0.001). Our study included patients aged between 49 and 69 years old, (mean age 58.6 years old, and the standard deviation 5.3). The minimum and the maximum periods of type II diabetes were 2 and 21 years, the mean and the standard deviation of which were 8.8 and 5.8, respectively. CONCLUSION With regard to the effectiveness of ginger herbal spray in rapidly increasing the patients' saliva and satisfaction as well as the acceptability of this type of medicine to treat dry mouths, ginger herbal spray could act as a new, cheap, and available treatment for diabetic patients with dry mouth.
