[PMID: 38435373 PMCID: PMC10906276 DOI: 10.2147/opth.s446804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 02/15/2024] [Indexed: 03/05/2024] Open
Abstract
Purpose To compare the effect of treatment with preservative-free dexamethasone, NSAIDs and trehalose/hyaluronic acid eye drops with the preservative benzalkonium chloride containing dexamethasone and NSAIDs after cataract surgery in dry versus non-dry eyes. Patients and Methods In this prospective randomized intervention study, dry eye tests were performed before and 6 weeks after cataract surgery. Patients were considered as having dry eye, SDE (sign of dry eye), if at least one of the following dry eye tests were abnormal; corneal fluorescein staining (CFS), non-invasive keratograph breakup time (NIKBUT) or tear osmolarity. Patients with SDE were randomly assigned to one of two groups. Group 1 patients were treated with dexamethasone and bromfenac eye drops with the preservative benzalkonium chloride (BAC). Group 2 patients were treated with preservative-free dexamethasone and preservative-free diclofenac, as well as a preservative-free lubricant with trehalose and hyaluronic acid both before and after surgery. Patients with normal tear film status acted as the control group (group 3) and received same treatment as group 1. Results A total of 215 patients were enrolled six weeks after surgery, the number of patients with SDE decreased significantly in groups 1 and 2 (p <0.001). Subjective symptoms and objective measures including osmolarity, NIKBUT, CFS, and tear film thickness (TFT) improved after surgery, tear production remained unchanged, while corneal sensitivity and meibomian gland dysfunction (MGD) parameters worsened. In the control group with normal tear-film status, SDE increased significantly after the surgery (p <0.001). There were no statistically significant differences in tear film parameters between the three groups after surgery. Conclusion After cataract surgery, patients with mild to moderate dry eyes may experience improved tear film status and reduced symptoms. However, we found no additional beneficial effect on dry eye parameters with treatment with preservative-free dexamethasone, NSAIDs, and lubricants compared to preservative-containing eye drops.

Abstract
AIM Dry eye disease (DED) is a prevalent ocular condition that significantly impacts individuals' quality of life and performance. It is charac-terized by the instability of the tear film, which causes ocular surface inflamma-tion and damage that leads to ocular symptoms. However, this study aimed to determine the prevalence of DED and identify associated risk factors among university students in western Saudi Arabia. METHODS A total of 402 university students participated in this study. The sample size was determined using Raosoft software (Raosoft, Inc., Seattle, WA), considering an estimated student population of 20,000. Data were collected between January and March 2023 through an online questionnaire distributed to the participants. The questionnaire comprised three sections, covering general information, behaviors related to digital device (DD) use, and the validated Arabic version of the Ocular Surface Disease Index (OSDI) questionnaire. OSDI scores were calculated, and the severity of DED was categorized using established cutoff points. RESULTS Among the 402 university students who took part in the survey, the majority (63.2%) were aged between 21 and 25 years, with females representing the dominant gender (72.9%). Notably, 90.8% of participants reported using DDs at bedtime. Over 60% of students had been using DDs for more than 10 years, and approximately 61.7% reported having more than six hours of daily screen time. Mobile devices were the most commonly used electronic devices (67.2%), and TikTok emerged as the most frequently used application (35.6%). Based on the OSDI criteria, 21.1% of students had mild DED symptoms, 14.9% had moderate symptoms, and 38.6% had severe symptoms. Hence, the prevalence of students exhibiting positive DED symptoms was 74.6%, while 25.4% were negative.

Symptomatic dry eye disease among university students. MEDICAL HYPOTHESIS, DISCOVERY & INNOVATION OPHTHALMOLOGY JOURNAL 2023; 12:70-77. [PMID: 38357613 PMCID: PMC10862028 DOI: 10.51329/mehdiophthal1472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 12/28/2023] [Indexed: 02/16/2024]
Abstract
Background Dry eye disease (DED) is a multifactorial condition often characterized by a reduction in tear film quantity or quality. This study aimed to determine the frequency of DED and its associated subjective symptoms among students of Mu'tah University. Methods In this cross-sectional study conducted at Mu'tah University, Mu'tah, Jordan, from January to April 2022, 489 students completed an online patient-reported DED symptom questionnaire and the ocular surface disease index (OSDI) questionnaire. Moreover, 106 participants underwent clinical examinations using the Schirmer test I and fluorescein tear breakup time (TBUT). Results Approximately 74.6% of the students self-reported experiencing DED symptoms, and 72.6% had an OSDI score > 12, which is considered the threshold for an abnormal ocular surface. Clinical examinations revealed low Schirmer test scores ( < 10 mm) in 26.4% (n = 28) and 25.5% (n = 27) of the right and left eyes, respectively. We observed low TBUT scores ( < 5 s) in 19.8% (n = 21) and 18.9% (n = 20) of the right and left eyes, respectively. We noted significant differences between the self-reported DED symptoms and the Schirmer test scores (P = 0.003 for both right and left eyes), TBUT (P < 0.001 for both right and left eyes), and OSDI score (P < 0.001 for each self-reported DED symptom). We observed a weak significant positive correlation between Schirmer test scores and TBUT in the right (r = + 0.30; P = 0.002) and left (r = + 0.34; P < 0.001) eyes; a negligible significant inverse correlation between OSDI scores and Schirmer test scores in the right (r = - 0.24; P = 0.013) and left (r = - 0.23; P = 0.019) eyes; and a negligible significant inverse correlation between the OSDI score and TBUT of the left eye (r = - 0.25; P = 0.011) but not of the right eye (r = - 0.17; P = 0.077). Conclusions The frequency of DED symptoms in this study was higher than that previously reported based on foreign statistics. The presence of self-reported DED symptoms was significantly associated with higher OSDI scores. Self-reported DED symptoms were more frequent than the abnormalities detected using objective methods. Therefore, a combination of subjective and objective measures may provide higher diagnostic yield for DED. Further studies are required to confirm this hypothesis.

Cationic nanoemulsion vs. 0.15% sodium hyaluronate artificial tears in the healing process following modern surface keratorefractive surgery. Eur J Ophthalmol 2023; 33:2178-2184. [PMID: 37070148 PMCID: PMC10590016 DOI: 10.1177/11206721231169540] [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: 04/04/2022] [Accepted: 03/25/2023] [Indexed: 04/19/2023]
Abstract
PURPOSE The aim of this study was to investigate the influence of artificial tears containing either cationic nanoemulsion (CCN) or sodium hyaluronate artificial tears (SH) on early postoperative healing after modern surface refractive surgery. MATERIALS AND METHODS In this multicenter, prospective, double-masked, parallel-group (1:1), comparative study, 129 patients (n = 255 eyes) were randomized to receive CCN (n = 128) or SH (n = 127) as an adjuvant treatment after either transepithelial photorefractive keratectomy (transPRK) or Epi-Bowman keratectomy (EBK). The patients' perspectives were gathered using the Ocular Surface Disease Index (OSDI) questionnaire, and uncorrected (UCVA), and corrected (BCVA) visual acuity were assessed before and one week and one month after the procedure. In addition, corneal epithelization and subjective assessment of visual blur and eye irritation on drop instillation were assessed at one week postoperatively. RESULTS No statistically significant differences were found between two groups in age, spherical equivalent refractive error, UCVA, BCVA or OSDI scores before the procedure. There was also no difference between groups in UCVA one week and one month after the procedure. However, statistically significantly lower OSDI scores were found one week and one month after the procedure in the CCN group. Moreover, blurred vision after use of the eye drops was observed less frequently in the CCN group than in the SH group. CONCLUSIONS The CCN and SH groups had similar postoperative UCVA. However the significantly lower OSDI scores and less frequently blurred vision after application of the eye drops in the CCN group suggest better subjective outcomes in this group.

The Effect of Sodium Hyaluronate Eye Drops 2, 4 or 6 Times a Day on Signs and Symptoms of Dry Eye Disease. Clin Ophthalmol 2023; 17:2945-2955. [PMID: 37822327 PMCID: PMC10563771 DOI: 10.2147/opth.s433709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 09/29/2023] [Indexed: 10/13/2023] Open
Abstract
Purpose A randomized clinical trial was run to evaluate the effectiveness of a preservative-free 0.4% sodium hyaluronate eye drop (LOF) in different dosage schemes to alleviate signs and symptoms of dry eye disease (DED). Methods A total of 116 subjects with mild-to-moderate DED were included, and 111 completed the study (from which 67.6% were female and 65.3% were users of oral contraceptives). Patients were randomly assigned to instill a drop of LOF either 2 (BID), 4 (QID) or 6 (6TD) times a day (at least 3 hours apart) for 30 days. The clinical parameters and symptom endpoints were Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), ocular surface staining, and conjunctival hyperemia. Other parameters evaluated were chemosis, best corrected visual acuity, and the incidence of adverse events (AE). Results There was a significant reduction in OSDI scores by day 30 in all groups. The recovery of the OSDI score back to normal values was observed in 51.4% of patients treated (50%, 48.6%, and 55.6% in BID, QID, and 6TD, respectively, p = 0.822). Similar improvement was observed for TBUT, 50.5% of patients increased this variable to >10 seconds (39.5%, 51.4%, and 61.1%, p = 0.175), and for ocular surface staining, ≥72% showed Grade 0. There were no significant differences among posology groups regarding ocular surface staining, conjunctival hyperemia, or any safety parameters. No overall improvement in OSDI and TBUT to normal values was noted for 31 patients (21 were female and 71.4% users of contraceptive drugs). Conclusion The ophthalmic use of preservative free LOF, 2, 4 or 6 times a day, may alleviate clinical parameters and symptoms in 50% of patients with mild-to-moderate DED after a one-month treatment. This improvement seemed to be less ubiquitous in patients within reproductive age and using oral contraceptives. Trial Registration This trial is registered at clinicaltrials.gov (NCT0704531).

Abstract
PURPOSE To compare different light-based devices, namely, intense pulsed light (IPL) and IPL with low-level light therapy (LLLT), in the treatment of meibomian gland dysfunction (MGD). METHODS This was a prospective, observational study that included patients with MGD. Group 1 included 58 eyes treated with IPL (eye-light®, Espansione Marketing S.p.A., Bologna, Italy), followed by LLLT (my-mask®, Espansione Marketing S.p.A., Bologna, Italy); Group 2 included 60 eyes treated with IPL (E>Eye®, E-Swin, Houdan, France); and Group 3 included 58 eyes treated with IPL (Thermaeye Plus®, OptiMed, Sydney, Australia). The presence of symptoms (Ocular Surface Disease Index (OSDI)) and ocular surface changes were evaluated at baseline, three weeks, and six months after treatment. RESULTS At week three, there was an improvement in the OSDI in all groups (p<0.001), without differences among them (p=0.339). The lipid layer thickness (LLT) increased in Groups 1 and 2 (p<0.001), with a similar variation (p=0.144). Patients with superior OSDI and lower LLT at baseline had the greatest improvement in the respective parameters (p<0.001). The basal tear flow increased in Group 1 (p=0.012). Corneal staining (CS) significantly decreased in Groups 2 (p<0.001) and 3 (p<0.001). At six months, compared to three weeks, there was further improvement in the OSDI (p<0.001) and the LLT (p=0.007), in Group 1, and an increase in the presence of CS in Group 3 (p=0.011). CONCLUSION IPL treatment led to a sustained decrease in patients' symptoms, even after six months. Different IPL devices seem to have different beneficial effects. Adding LLLT to IPL appears to have an additional long-term beneficial effect as well as positive effects on the lacrimal gland.

Intense Pulsed Light Therapy in the Treatment of Dry Eye Diseases: A Systematic Review and Meta-Analysis. J Clin Med 2023; 12:jcm12083039. [PMID: 37109374 PMCID: PMC10145895 DOI: 10.3390/jcm12083039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 04/06/2023] [Accepted: 04/19/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Intense pulsed light therapy (IPL) is a recently developed way of treating dry eye disease (DED). During the last decade, there was a multiplication of trials studying IPL efficacy. The goal of this review is to summarize the most important and significant results of these trials estimating effect sizes. METHODS The PubMed and sciencedirect databases were searched using a PICO model-based approach. Randomized controlled trials including at least 20 patients with DED and no other eye condition, with a control group and break-up time or symptom scores data available for extraction were included in this review. Statistical analysis evaluated the tear break-up time (TBUT), non-invasive break-up time (NIBUT), ocular surface disease index (OSDI), and standard patient evaluation of eye dryness (SPEED). Three comparisons were carried on for each outcome: longest follow-up values vs. baseline in the treatment group, longest follow-up values in the treatment group vs. control group, and changes from baseline in the treatment group vs. control group. A subgroup analysis was carried on. RESULTS Eleven randomized controlled trials, published between 2015 and 2021 were included in this systematic review with 759 patients in total. The longest follow-up values vs. baseline in the treatment group analyses were significantly in favor of IPL for all the parameters studied for instance: NIBUT (effect size (ES), 2.02; 95% confidence interval (CI), (1.43; 2.62)), TBUT (ES, 1.83; 95% CI, (0.96; 2.69)), OSDI (ES, -1.38; 95% CI, (-2.12; -0.64)) and SPEED (ES, -1.15; 95% CI, (-1.72; -0.57)). The longest follow-up values in the treatment group vs. control group analyses, and, the change from baseline in the treatment group vs. control group analyses, were both significantly in favor of IPL for NIBUT, TBUT, and SPEED but not for OSDI. CONCLUSIONS IPL seems to have a positive effect on tear stability evaluated by the break-up times. However, the effect on DED symptoms is less clear. Some confounding factors such as the age and the IPL device used influence the results indicating that the ideal settings still need to be found and personalized for the patient.

Abstract
Objective: To assess the efficacy of 0.1% cyclosporine A (CsA) cationic emulsion (CE) in the treatment of dry eye disease (DED) in terms of ocular surface disease index (OSDI). Methods: DED patients with corneal fluorescein staining grade (CFS) ≤ 3 on the Oxford scale and Schirmer test score < 10 mm/ 5 min were enrolled for once-daily CsA use in this observational, prospective, one-center study. Efficacy of CE at 30, 60, and 90-day follow-up visit was evaluated using OSDI questionnaire. Both the overall OSDI score and the outcomes for all subscales - ocular symptoms (OS), vision-related function (VRF) and environmental triggers (ET) were considered. Results: Twelve patients (10 women and 2 men), whose baseline OSDI ranged between 27.08 and 70.03 mm (48.2 ± 11.8), were included. Their achieved mean scores for subscales such OS, VRF and ET were 66.6 ± 16.8, 42.2 ± 12.0 and 42.2 ± 12.5, respectively. Statistically significant results were obtained after 30 days for OSDI (45.5 ± 10.0; p=0.011), whereas after 90 days for both OSDI (35.4 ± 7.4; p=0.003) and OS (47.2 ± 10.9; p=0.005), VRF (30.5 ± 6.1; p=0.003) and ET (33.3 ± 11.2; p=0.008). Conclusions: CsA CE significantly reduced symptoms of patients with DED. Recovery was the most successful after 90 days of treatment and included OSDI, OS, VRF and ET. Abbreviations: CE = cationic emulsion, CFS = corneal fluorescein staining, CsA = cyclosporine A, DED = dry eye disease, ET = environmental triggers, OS = ocular symptoms, OSDI = ocular surface disease index, VRF = vision-related function.

Abstract
Purpose This present prospective, cross-sectional study aims to comprehensively evaluate the ocular surface in asymptomatic patients with diffuse blebs after trabeculectomy versus chronic anti-glaucoma medication use and compare it with the age-matched normal population. Methods Objective clinical evaluation was done by tear film break-up time (TBUT) and Schirmer's test (ST) in the three groups-trabeculectomy >6 months with a diffuse bleb (Wurzburg bleb classification score ≧10), chronic anti-glaucoma medication (AGM >6 months) group, and normal population. In all groups, tear film osmolarity was checked with the TearLab® device (TearLab Corp., CA, USA), and subjective evaluation was performed by administering Ocular Surface Disease Index (OSDI) questionnaire. Patients already on chronic lubricants or any other drug for the treatment of dry eyes (viz. steroids, cyclosporin) or having symptoms suggestive of an abnormal ocular surface, who had undergone refractive or intraocular surgery, and contact lens users were excluded. Results In total, 104 subjects/eyes were recruited over 6 weeks. Thirty-six eyes recruited in the trab group were compared with 33 eyes studied in the AGM group, and both these groups were compared to 35 normal eyes. When compared to normals, TBUT and ST were significantly lower (P = 0.003 and 0.014) and osmolarity and OSDI were statistically significantly higher (P = 0.007 and 0.003) in the AGM group, whereas only TBUT was statistically significantly different (P = 0.009) when the trab group was compared to normals. Also, when the trab group was compared to the AGM group, ST was found to be higher (P = 0.003) and osmolarity was lower (P = 0.034). Conclusion To conclude, ocular surface is affected even in asymptomatic patients on AGM but near normalcy is possible following trabeculectomy when blebs are diffuse.

Abstract
Purpose Aim of this study was to compare the efficacy of sodium hyaluronate (SH) and carboxymethyl cellulose (CMC) eye drops in treating mild to moderate dry eye disease in terms of relief of symptoms, mean change in tear film breakup time, Schirmer's test, and impression cytology of conjunctiva from baseline. Methods An observational study was carried out during a 2-year period in our tertiary referral hospital. The study consisted of 60 patients randomly allotted to two groups to receive SH and CMC eye drops for an 8-week period. Ocular surface disease index, tear film breakup time, and Schirmer's test were performed at baseline visit and 4 and 8 weeks of treatment, and impression cytology of conjunctiva was performed at baseline and 8 weeks. Results Significant improvement in patient symptoms, tear film breakup time, and Schirmer's test from baseline was seen in both SH and CMC groups at 8 weeks posttreatment, whereas impression cytology of conjunctiva in both groups did not show significant improvement at 8 weeks of treatment. Data analysis using unpaired t-test showed comparable results. Conclusion Both CMC and SH demonstrated equal efficacy in treating mild to moderate dry eye disease.

Abstract
Aim To assess the severity of dry eye disease (DED) in humans, its impact on quality of life (QoL) and to grade the damage incurred by the anterior ocular surface in patients diagnosed with type 2 diabetes mellitus (T2DM). Patients and methods Forty-six patients (mean age ± SD = 63.8 ± 6.7 years) diagnosed with T2DM were enrolled in the experimental group and 26 healthy individuals constituted the control group (67.9 ± 8.9 years). The diagnosis and gradation of DED were conducted in accordance with the International Task Force severity grading scheme. Disease-specific questionnaires were used to obtain the Ocular Surface Disease Index (OSDI) and assess the negative effects of the disease on the patient's QoL. The severity of conjunctival redness and corneal/conjunctival staining was assessed by Efron and Oxford scales, respectively. Results According to OSDI scores, the entire experimental group presented symptoms of DED: 54.4% were diagnosed with mild DED and 46.6% with moderately severe DED. No cases of severe DED were diagnosed in either the experimental or control group. In the control group, 57.7% of individuals did not have the disease. A significant difference between the experimental and control groups was recorded for both OSDI scores (p < 0.01) and health-related QoL (p < 0.01). It was observed that keratopathy influenced the mean OSDI values of patients. The mean OSDI value was 25.14 ± 3 in the experimental group diagnosed with keratopathy, 19.3 ± 3.5 in the subgroup with no indications of corneal injury (p = 0.000002), and 13.0 ± 3.0 in the control group (p < 0.000002). Based on the DEWS scheme, a grade I severity level was observed in 46% of control subjects and 33% of patients diagnosed with T2DM (p = 0.4915); grades II and III were detected in the bulk of the experimental group (p = 0.0051; p = 0.1707). None of the subjects in the control or experimental groups manifested grade IV severity of DED. Conclusion In comparison to healthy adults, DED adversely impacts the QoL of type 2 DM patients, regardless of the disease's association with keratopathy.

Materials and Methods The study included 25 right eyes of 25 male volunteers aged 25-30 years who had never used SiHCLs before. ocular surface disease index (OSDI), tear break-up time, Schirmer test, tear meniscus area, strip meniscometry tube, corneal sensitivity, and corneal subbasal nerve morphology were evaluated before and after 1 month of CL use. Results OSDI was 10.6±1.1 before CL use and 17.2±1.2 after 1 month of CL use (p<0.01). Schirmer test distance was 16.3±2.3 mm before and 14.3±1.9 mm after 1 month of CL use (p>0.05). Tear film break-up time was 7.1±0.4 s before and 6.2±0.3 s after CL use (p>0.05). The tear meniscus area was 0.026±0.002 mm2 before and 0.024±0.001 mm2 after 1 month of CL use (p>0.05). Strip meniscometry tube results were 5.4±0.9 mm before and 4.9±0.8 mm after 1 month of CL use (p>0.05). Corneal sensitivity values were 3.2±0.4 mm before and 2.95±0.3 mm after 1 month of CL use (p>0.05). Dendritic cell density evaluated by confocal microscopy was 14.84±3.1 cells/mm2 before and 32.57±4.2 cells/mm2 after 1 month of CL use (p<0.01). Subbasal nerve tortuosity was 0.92±0.2 before and 1.03±0.2 after 1 month of CL use (p>0.05). Subbasal nerve density was measured as 4726±310 pixels/frame before and 4570±272 pixels/frame after 1 month of CL use (p>0.05). Conclusion After a month of SiHCL use, no significant changes were observed in tear secretion, corneal sensitivity, tear meniscus volume, subbasal corneal nerve density, reflectivity, or tortuosity, while a significant increase was found in OSDI and dendritic cell density.

Pulsed Light Therapy in the Management of Dry Eye Disease: Current Perspectives. Clin Ophthalmol 2022; 16:3883-3893. [PMID: 36452044 PMCID: PMC9703996 DOI: 10.2147/opth.s349596] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 11/14/2022] [Indexed: 08/08/2023] Open
Abstract
PURPOSE To review the indications and efficacy of Intense Pulsed Light (IPL) application in the treatment of Meibomian Gland Dysfunction (MGD). Its main purpose is to describe its physiology, efficacy, indications, and adverse effects. PATIENTS AND METHODS A two database (PubMed, EMBASE) search was performed from July 2017 to July 2022 using the MeSH terms ("Intense Pulsed Light" AND ("Meibomian Gland Dysfunction" OR "Dry Eye"). We included randomized studies and systematic reviews with meta-analysis. Exclusion criteria were non-randomized trials, studies enrolling non-MGD dry eye disease, and other works older than 5 years. RESULTS Current literature shows that IPL is an effective and safe treatment modality for severe dry eye. Available evidence shows improvement of symptoms and objective indicators, such as noninvasive breakup time, thickness of lipid layer, and Schirmer test. However, our review concluded that the beneficial effects of IPL may lose some efficacy at 6-months after the initial session, and subsequent sessions may be required. Thus, IPL treatment should not be considered as first-line therapy for MGD but instead as an adjuvant option to the standard of care. The optimal treatment modality remains unknown and should be tailored according to each patient's phenotype, clinician's experience, and available technology. There is evidence that IPL treatment may down-regulate pro-inflammatory markers (such as interleukin (IL) 6, IL17a, IL-1) and Prostaglandin E2 (PGE2). CONCLUSION MGD is a multifactorial disease and IPL treatment seems a promising treatment modality. Despite this, more evidence is needed to study its benefits - since this is an emerging technology, it is expected an increase in comparative studies in the following years, with longer follow-up periods, which may enable more precise conclusions about this treatment modality.

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.

Combination of 0.05% Azelastine and 0.1% Tacrolimus Eye Drops in Children With Vernal Keratoconjunctivitis: A Prospective Study. Front Med (Lausanne) 2021; 8:650083. [PMID: 34604246 PMCID: PMC8484704 DOI: 10.3389/fmed.2021.650083] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 08/18/2021] [Indexed: 11/29/2022] Open
Abstract
Aims: To compare the efficacy of the combination of 0. 05% azelastine and 0.1% tacrolimus eye drops with 0.1% tacrolimus monotherapy in pediatric patients with vernal keratoconjunctivitis (VKC). Methods: Prospective study. Seventy-six patients with VKC were randomized 1:1 into monotherapy group with 0.1% tacrolimus or combination therapy group with 0.1% tacrolimus and 0.05% azelastine. The Ocular Surface Disease Index (OSDI) scores and the signs of conjunctival hyperemia, corneal involvement, and palpebral conjunctiva papillae were assessed at baseline and at 1, 2, and 6 weeks after treatment. Results: Two groups were comparable in age, sex, duration of VKC, OSDI, and clinical signs of VKC at baseline. Significant improvements in OSDI score and clinical signs were observed in both groups at all follow-up visits (all p < 0.001), compared with baseline. The combination therapy group showed a larger decrease in OSDI score from baseline (10.30 ± 0.9) compared with monotherapy group (7.30 ± 0.7, p =0.0085) at 1 week. Greater improvements in conjunctival hyperemia and conjunctival papillae were identified in the combination therapy group, compared with in the monotherapy group, at all follow-up visits (all p < 0.05). The corneal involvement scores in the combination group is significantly lower than the monotherapy group at 2 weeks after the treatment (p = 0.0488). No severe adverse effect was found in either group during the study. Conclusions: Compared with a monotherapy of 0.1% tacrolimus, the combination of 0.05% azelastine and 0.1% tacrolimus eye drops lead to faster and greater improvements in clinical signs and symptoms of vernal keratoconjunctivitis in pediatric patients.

Abstract
Purpose: To compare the suitability of the Ocular Surface Disease Index (OSDI) and the 5-item Dry Eye Questionnaire (DEQ-5) in Indian patients with dry eyes. Methods: This cross-sectional study evaluated the OSDI and DEQ-5 in patients with tear film abnormalities. Tear film breakup time, tear film height, Schirmer’s I, lissamine green staining, and meibomian gland expressibility were performed on each patient. Results: There were 101 patients with symptoms and/or signs of tear film abnormality. Both OSDI and DEQ-5 questionnaires significantly correlated (ρ = 0.566, P < 0.0001) with each other. The OSDI questionnaire showed a good correlation with all dry eye tests, whereas the DEQ-5 correlated significantly only with the tear film breakup time and the lissamine green score. None of the questionnaires correlated with meibomian gland expressibility. The Bland–Altman analysis revealed a marginal bias (−0.01 unit) for DEQ-5. The DEQ-5 scored higher in patients with mild symptoms. While 101 (100%) patients answered all the questions in the DEQ-5, only 19 (18.8%) patients answered all the questions in the OSDI questionnaire. The least responses were recorded in the vision-function-related and environmental trigger subscales of the OSDI. Conclusion: The OSDI and DEQ-5 scores showed a moderate correlation. The OSDI questionnaire correlated with a higher number of dry eye tests than the DEQ-5. The large number of skipped questions in the vision-function-related and environmental trigger subscales of the OSDI suggests that the questionnaire is not adequately adapted to the Indian population. Patients with a negative OSDI score should be reassessed with the DEQ-5 to exclude symptom positivity.

Reliability of Chinese web-based ocular surface disease index questionnaire in dry eye patients: a randomized, crossover study. Int J Ophthalmol 2021; 14:834-843. [PMID: 34150537 DOI: 10.18240/ijo.2021.06.07] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Accepted: 01/22/2021] [Indexed: 01/11/2023] Open
Abstract
AIM To assess the reliability of web-based version of ocular surface disease index in Chinese (C-OSDI) on clinically diagnosed dry eye disease (DE) patients. METHODS A total of 254 Chinese participants (51% male, 129/254; mean age: 27.90±9.06y) with DED completed paper- and web-based versions of C-OSDI questionnaires in a randomized crossover design. Ophthalmology examination and DED diagnosis were performed prior to the participants being invited to join the study. Participants were randomly designated to either group A (paper-based first and web-based second) or group B (web-based first and paper-based second). Final data analysis included participants that had successfully completed both versions of the C-OSDI. Demographic characteristics, test-retest reliability, and agreement of individual items, subscales, and total score were evaluated with intraclass correlation coefficients (ICC), Spearman rank correlation, Wilcoxon test and Rasch analysis. RESULTS Reliability indexes were adequate, Pearson correlation was greater than 0.8 and ICCs range was 0.827 to 0.982; total C-OSDI score was not statistically different between the two versions. The values of mean-squares fit statistics were very low compared to 1, indicating that the responses to the items by the model had a high degree of predictability. While comparing the favorability 72% (182/254) of the participants preferred web-based assessment. CONCLUSION Web-based C-OSDI is reliable in assessing DED and correlation with the paper-based version is significant in all subscales and overall total score. Web-based C-OSDI can be administered to assess individuals with DED as participants predominantly favored online assessment.

Abstract
PURPOSE This study aimed to analyze the changes in meibomian glands (MGs) and tear film layer over time in patients taking systemic isotretinoin treatment. METHODS Patients who received systemic isotretinoin treatment between 4 and 8 months were prospectively followed up. In addition to full ophthalmologic examination, MG dysfunction (MGD), noncontact meibography, noninvasive and invasive tear break-up time (TBUT), ocular surface disease index (OSDI), corneal staining, and eyelid margin abnormality scores were recorded before, during, and after treatment. RESULTS A total of 88 eyes of 88 patients were included in the study. The right eyes of all the patients were included. The mean age of the patients was 21 ± 2.9 years. Of the 88 patients, 70 (79.6%) were females and 18 (20.4%) were males. Before the treatment, MGD, noncontact meibography, first noninvasive TBUT, mean noninvasive TBUT, invasive TBUT, OSDI, corneal staining, and eyelid margin abnormality scores were 0.29 ± 0.45, 4.93 ± 3.50, 13.78 ± 3.89 s, 14.47 ± 3.09 s, 12.96 ± 3.61 s, 0.54 ± 1.00, 0.04 ± 0.20, and 0.09 ± 0.28, respectively. Twelve months after the end of treatment, the scores were 0.97 ± 0.87 (p < 0.001), 9.62 ± 3.89 (p < 0.001), 11.24 ± 3.52 s (p < 0.001), 12.34 ± 3.02 s (p < 0.001), 11.31 ± 2.90 s (p < 0.001), 1.90 ± 2.44 (p < 0.001), 0.20 ± 0.40 (p < 0.001), and 0.56 ± 0.49 (p < 0.001), respectively. CONCLUSION Systemic isotretinoin treatment causes morphological changes in the MGs. However, this treatment may negatively affect the tear film layer of patients. Some of these changes may persist for a long time even if the treatment is discontinued.

Abstract
Purpose: To evaluate the correlation between ocular surface disease (OSD) and functional status among elderly population over 60 years old in Hong Kong.Methods: Chinese subjects above 60 years old were recruited from the Ophthalmology clinic in Hong Kong West Cluster. Subjects demographic and questionnaires to evaluate the functional status were used to correlate with OSD objectively with clinical examination to assess the meibomian gland dysfunction (MGD), corneal staining, Schirmer's test and tear break-up time (TBUT); and subjectively with ocular surface disease index (OSDI).Results: Twenty-eight patients were recruited, with a mean age of 71.5 ± 6.8 years. There was good correlation between the findings of the two eyes for bilateral measurements. Corneal staining was present in 75% of the subjects, while 92.9% of them had positive MGD grading. TBUT was reduced in 85.7% of the subjects. There is a negative association between MGD grading and Barthel index (r = -0.55, p< .01), indicating worse activities of daily living is related to worse MGD. OSDI is negatively associated with Schirmer's test (r = -0.49, p< .01). A negative correlation is also found between TBUT value and corneal staining (r = -0.58, p< .01).Conclusions: There is a high prevalence of OSD among our subjects. Lower Barthel index (indicating worse Lawton's instrumental activities of daily living) is associated with worse MGD grading. In elderly with poor functional status, care should be taken to manage their OSD.

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
The aim of this study was to compare patient-reported symptoms of dry eye disease (DED) between the Japanese version of the Ocular Surface Disease Index (J-OSDI) and the Dry Eye-Related Quality-of-Life Score (DEQS). A total of 169 participants were enrolled between September 2017 and May 2018. Patients were administered the J-OSDI and DEQS questionnaires at their first (baseline) and follow-up visits to evaluate DED-related symptoms. The correlations between the J-OSDI total score and DEQS (Frequency and Degree) scores were evaluated using Pearson’s correlation coefficient, and their clinical differences were assessed using the Bland–Altman analysis. At the baseline visit, the J-OSDI score and DEQS (Frequency and Degree) were significantly correlated (r = 0.855, r = 0.897, respectively). Moreover, a significant correlation was found between the J-OSDI score and DEQS (Frequency and Degree) at the follow-up visit (r = 0.852, r = 0.888, respectively). The Bland–Altman analysis revealed a difference (bias) of 4.18 units at the baseline and 4.08 units at the follow-up between the scores of the two questionnaires. The J-OSDI and DEQS were significantly correlated with negligible score differences, suggesting that the J-OSDI can be reliably used for Japanese patients, allowing for cross-country comparisons.

Abstract
Purpose To compare the effects of eyelid treatment with the iLUX MGD Treatment System and the LipiFlow Thermal Pulsation System on objective and subjective parameters of meibomian gland function and symptoms. Patients and Methods In this randomized, open-label, controlled, multicenter clinical trial, both eyes of 142 patients aged ≥18 years with Ocular Surface Disease Index (OSDI) scores ≥23, total meibomian gland scores (MGS) ≤12 in the lower eyelid of each eye, and tear break-up time (TBUT) <10 s were randomized 1:1 to iLUX or LipiFlow treatment, with stratification by test center. The primary effectiveness endpoints were changes in total MGS (masked) and TBUT from baseline to 4 weeks. The secondary effectiveness endpoint was changed in OSDI score from baseline to 4 weeks. Results Both devices significantly improved effectiveness outcomes, with no differences between the two devices. At the 4-week visit, mean MGS, TBUT, and OSDI scores improved at least 16.9 ± 11.5, 2.6 ± 3.2 s, and 28.0 ± 22.8, respectively, across treatment groups and treated eyes. Four device/procedure-related events occurred in the iLUX group, compared with none in the LipiFlow group, but there were no device-related adverse events that involved changes in lid margins, eyelids, or lash integrity. Corneal staining, intraocular pressure, and visual acuity did not differ in the two groups. Conclusion Both treatments produced significant improvements in meibomian gland function and symptoms. For all effectiveness measures, there were no statistically significant differences between the two treatments.

Abstract
OBJECTIVES The Ocular Surface Disease Index (OSDI) questionnaire is widely used to evaluate subjective symptoms of dry eye disease (DED) as a primary diagnostic criterion. This study aimed to develop a Japanese version of the OSDI (J-OSDI) and assess its reliability and validity. DESIGN AND SETTING Hospital-based cross-sectional observational study. PARTICIPANTS A total of 209 patients recruited from the Department of Ophthalmology at Juntendo University Hospital. METHODS We translated and culturally adapted the OSDI into Japanese. The J-OSDI was then assessed for internal consistency, reliability and validity. We also evaluated the optimal cut-off value to suspect DED using an area under the receiver operating characteristic curve (AUC) analysis. PRIMARY OUTCOME MEASURES Internal consistency, test-retest reliability and discriminant validity of the J-OSDI as well as the optimal cut-off value to suspect DED. RESULTS Of the participants, 152 had DED and 57 did not. The J-OSDI total score showed good internal consistency (Cronbach's alpha=0.884), test-retest reliability (interclass correlation coefficient=0.910) and discriminant validity by known-group comparisons (non-DED, 19.4±16.0; DED, 37.7±22.2; p<0.001). Factor validity was used to confirm three subscales within the J-OSDI according to the original version of the questionnaire. Concurrent validity was assessed by Pearson correlation analysis, and the J-OSDI total score showed a strong positive correlation with the Dry Eye-Related Quality-of-Life Score (γ=0.829). The optimal cut-off value of the J-OSDI total score was 36.3 (AUC=0.744). CONCLUSIONS The J-OSDI was developed and validated in terms of reliability and validity as an effective tool for DED assessment and monitoring in the Japanese population.

Abstract
Purpose To assess optical quality dynamics using a double-pass (DP) system in patients with dry eye disease (DED). Methods Seventy-six eyes with DED and 44 control subjects were enrolled in this study. Each patient underwent ocular surface evaluation including fluorescein corneal staining and Schirmer’s II test. Ocular Surface Disease Index (OSDI) questionnaire was used to assess subjective symptoms. Optical quality dynamics and tear film instability was analyzed using a DP system (HD AnalyzerTM, Visiometrics, Spain). Mean objective scatter index (OSI), maximum and minimum OSI, difference between maximum and minimum OSI (ΔOSI) were recorded with 40 consecutive scans over 20 s. Results The DED group had pronounced impairment of optical quality compared to the control group. Mean OSI (4.29±4.07), minimum (3.22±3.51) and maximum (5.72±4.52) OSI, ΔOSI (2.50±1.96), OSDI score (36.94±16.55), and fluorescein corneal staining (0.79±0.96) were statistically significantly higher than controls (p<0.05). Schirmer’s II test was statistically significantly lower in the DED group compared to controls (10.08±7.85, 26.41±6.75, respectively; p<0.001). Three patterns of dynamic changes of OSI were proposed: ladder (continuous increase of OSI), seesaw (instability of OSI without improvement after blinking), and plateau (steady-high OSI). The ladder group showed the highest value of maximum OSI (6.93±4.13; p=0.03) and ΔOSI (3.76±2.08; p<0.001). Conclusion DP imaging system provides an objective measurement of the visual quality in DED. Tear film instability may be assessed by dynamic changes of OSI over 20 s. In particular, the highest OSI values were observed in the ladder pattern group.

Abstract
Objectives: The aim of this study was to evaluate the prevalence of dry eye symptoms among lecturers. Materials and Methods: The study included 254 lecturers employed at Mersin University. The lecturers were selected by simple random sampling from lists obtained from the personnel department. Data were obtained between November 15 and December 15, 2017 using a questionnaire developed by the researchers and the Ocular Surface Disease Index (OSDI). The data were evaluated using descriptive statistics, Student’s t test, ANOVA, and correlation tests with the SPSS package program. Results: Of the lecturers who participated in the study, 52.8% were male and 47.2% were female, and the mean age was 39.29±9.41 years. According to OSDI scores, 20.5% of the participants had mild, 15% had moderate, and 36.5% had severe disease. There were significant differences in mean OSDI score based on sex (p<0.001), alcohol use (p=0.01), continuous drug use (p=0.03), wearing glasses (p=0.04), history of dry eye (p<0.001), and presence of dry eye symptoms (p<0.001). There were also significant differences between the OSDI score categories in terms of sex (p<0.001), smoking status (p=0.04), wearing glasses (p=0.03), history of dry eye (p<0.001), and presence of dry eye symptoms. The only factor significantly correlated with OSDI score was daily duration of computer usage (p=0.009). Conclusion: Our study showed that a substantial proportion of lecturers experience dry eye symptoms, and OSDI scores were associated with daily duration of computer use. Determining the factors associated with dry eye is important for the planning of preventive interventions.

Combined low level light therapy and intense pulsed light therapy for the treatment of meibomian gland dysfunction. Clin Ophthalmol 2019; 13:993-999. [PMID: 31354233 PMCID: PMC6573774 DOI: 10.2147/opth.s213664] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2019] [Accepted: 05/21/2019] [Indexed: 12/14/2022] Open
Abstract
Purpose To evaluate the effects of combined intense pulsed light therapy (IPL) and low-level light therapy (LLLT) on clinical measures of dry eye related to severe meibomian gland disease (MGD) in subjects unresponsive to previous medical management. Patients and Methods This was a retrospective chart review of patients treated by 4 physicians at 3 centers. All patients were documented treatment failures with traditional pharmaceutical therapy. They all had their MGD evaluated before treatment using a grading scale (0-4), tear breakup time in seconds and the Ocular Surface Disease Index (OSDI) questionnaire. To be included, all patients had to have had a short course of adjunct pharmaceutical or device-related therapy, along with a combined IPL/LLLT treatment. As well, a second MGD evaluation with the same three measures had to have been conducted 1-3 months post treatment. Results A total of 460 eyes of 230 patients were identified for inclusion in the data set. Mean OSDI scores were significantly lower after treatment; 70.4% of patients had pretreatment OSDI scores indicative of dry eye; this dropped to 29.1% of patients after treatment. A 1-step or greater reduction in MGD grading was observed in 70% of eyes, with 28% of eyes having a 2-step or greater reduction. Tear breakup time was ≤6 seconds in 86.7% of eyes pretreatment, dropping to 33.9% of eyes after treatment. There were no ocular or facial adverse events or side effects related to the combined light treatment. Conclusion The use of combined IPL/LLLT for the treatment of severe MGD appears to be beneficial in patients who have failed topical and/or systemic therapy.

Abstract
Objectives: To assess ocular abnormalities in psoriatic patients (new-cases versus patients under treatment) in comparison with healthy controls.Methods: A total of 200 psoriatic patients and 100 healthy controls were enrolled in this prospective, observational study. The demographic data of the individuals were recorded. Dermatological and ophthalmologic examinations were conducted; ocular surface disease index (OSDI), Schirmer's and tear break-up time (TBUT) values were also measured.Results: The mean values of TBUT and Schirmer's tests in patients were significantly lower than the controls and significantly higher scores of OSDI were observed among patients compared to the controls (p < .0001); dry eye disease was more frequent in the patients than the healthy subjects (p = .001). Other ocular findings including cataract and uveitis were not significantly different between the groups. Although no significant differences were found between the ocular findings of new cases and patients under treatment, ocular findings in cases under treatment were associated with the type of treatment and more frequent in those treated with methotrexate, followed by acitretin and biologic drugs.Conclusions: Ocular surface problems in psoriatic patients are more common than previously thought; in addition to the role of treatment modalities, psoriasis itself and a probable systemic inflammation may play an important role.Key PointsThere are limited case-control studies about ocular manifestations in psoriasis and also its pathogenesis is not yet clear.This study shows that ocular surface problems in psoriatic patients are higher than healthy subjects; in addition to the role of treatment modalities, psoriasis itself and a probable systemic inflammation may play a pivotal role.Regular ophthalmological evaluations are recommended in psoriatic patients especially those with more severe and chronic form of the disease, to prevent any complications.

Abstract
AIM To suspect laryngopharyngeal reflux (LPR) in patients with ocular surface disease (OSD). METHODS The present study evaluated a group of subjects with OSD assessing the Ocular Surface Disease Index (OSDI) and the Reflux Symptom Index (RSI) to detect patients with suspected LPR and define a possible relationship between tests. RESULTS Two hundred and ninety subjects (175 females, mean age: 60.41±15.68y) were consecutively visited at ophthalmologist offices. One hundred and one (34%) patients had pathological RSI (>13) and consequently a suspected LPR. CONCLUSION The current study shows that suspected LPR may be common (34%) in patients with OSD and a suspected LPR may be considered in OSD patients when RSI score is >13 and OSDI score is >42.

Abstract
OBJECTIVE To describe a post hoc analysis comparing the effect of a hyaluronic acid (HA)-trehalose solution to an established eyedrop solution containing HA alone using Ocular Surface Disease Index (OSDI) score <19 as a threshold for moderate to severe dry eye disease (DED). METHODS A phase III, randomized, controlled, single-blind, multicenter study was conducted in France and Tunisia to evaluate the efficacy and safety of HA-trehalose (N = 52) and HA (N = 53) administered for 84 days. Eligible patients had moderate to severe DED with OSDI ≥18. Here the results of a post hoc analysis of the percentage of patients with OSDI <19 on Day 35 and Day 84 are reported. RESULTS Significantly more patients had OSDI <19 at Day 84 in the HA-trehalose group than in the HA group (78.8% versus 58.5%; p = .025). At Day 35, more patients had OSDI <19 in the HA-trehalose group than in the HA group, but this difference was not statistically significant. Furthermore, approximately twice as many patients in the HA group (41.5%) still had OSDI 19-100 at Day 84 compared to the HA-trehalose group (21.2%). CONCLUSIONS This data supports the addition of trehalose to HA-containing eyedrop solutions to provide better symptomatic relief from moderate to severe DED, based on an OSDI score of <19 after 84 days of treatment.

Abstract
PURPOSE To evaluate the ocular findings in patients with rheumatoid arthritis (RA) treated with disease-modifying antirheumatic drugs (DMARDs) such as methotrexate (MTX) or MTX with biological agents. METHODS One hundred and twelve eyes of 56 patients with RA and treated with MTX or MTX with biological agents were included in the study. Patients were divided into two groups using DMARDs only (group 1) and patients using DMARDs and biologic agents together (group 2). In both groups; Schirmer's II test, tear film break-up time (tBUT), central corneal thickness (CCT), corneal volume (CV), intraocular pressure (IOP) measurement, and anterior segment and fundus examinations of the eye with slit lamp were carried out. Ocular surface disease index (OSDI) score questionnaire were performed. RESULTS Thirty-eight patients with a mean age of 53.00 ± 8.19 years were in group 1 and 18 patients with a mean age of 51.00 ± 9.54 years were in group 2. The mean duration of RA was 6.89 ± 7.96 years in group 1 and 5.70 ± 9.00 years in group 2. There was a statistically significant difference between two groups with tBUT, CCT, CV, IOP (p < 0.05) and there was no significant difference with age, sex, disease duration, disease activity, and Schirmer's II test (p > 0.05). The disease duration showed a significant moderate negative correlation with CCT and CV in group 2 (p < 0.05). CONCLUSIONS Although tBUT values were significantly higher in the combination treatment group, CCT and CV values were significantly lower. Due to the decrease in corneal thickness, IOP was determined to be significantly lower.

Abstract
OBJECTIVES To evaluate dry eye symptoms and clinical tear film alterations in patients with chronic renal failure (CRF). MATERIALS AND METHODS Thirty-five non-diabetic CRF patients undergoing hemodialysis, and 31 healthy individuals were enrolled. An ocular surface disease index questionnaire (OSDI) was administered, and after a complete ocular examination, Schirmer and tear break-up time (TBUT) tests were performed. RESULTS OSDI scores were significantly higher (p<0.01) and TBUT tests were significantly lower (p=0.01) in CRF patients than in the control group. Schirmer test results were also lower in the CRF patients group, but lacked statistical significance (p=0.20). CONCLUSION Patients with CRF should be advised to obtain an ophthalmic examination, especially for dry eye.

Abstract
PURPOSE To determine the influence of ocular complications on quality of life (QoL) 3 years after allogeneic stem cell transplantation (allo-SCT). METHODS All 54 adult patients that underwent and survived allo-SCT in 2006/2007 in our centre received two questionnaires (VFQ-25: visual function questionnaire-25 and OSDI: ocular surface disease index). In addition, the following data were included: gender, age, underlying disease, presence of chronic and/or ocular graft-versus-host disease (GVHD), number of visits to an ophthalmologist, manifestations of dry eye disease, the duration of follow-up and treatment for ocular GVHD. RESULTS Ocular GVHD developed in 26% (14 of 54) of patients and 71% (10 of 14) received treatment for ocular GVHD. The presence of ocular GVHD correlated with the severity of systemic GVHD (correlation coefficient: 0.52, p = 0.00). The Karnofsky scores were significantly lower in the patients with ocular GVHD compared to the patients with no ocular GVHD (p = 0.001). Karnofsky scores were weakly correlated with the severity of systemic GVHD (correlation coefficient: 0.25, p = 0.03. Three years after the all-SCT, OSDI and VFQ-25 scores were significantly impaired in patients with ocular GVHD [mean: 76.5; range (46.1-100) and mean: 31.1; range (0-72.9)] compared to patients with no ocular GVHD [mean: 89.4; range (45.2-100) and mean: 12.9; range (0-58.3); p = 0.02]. The scores of the VFQ-25 were significantly lower in the domains of general health, ocular pain, social functioning and role difficulties. CONCLUSION The long-term vision-related QoL measured by the OSDI and VFQ-25 was impaired in patients with ocular GVHD.

Abstract
Ocular surface disease (OSD) is common among glaucoma patients. Clinical assessment of OSD can be challenging. This review focuses on some of the limitations relating to both subjective and objective measures of OSD, including dry eye. A survey of the literature was conducted to identify the caveats associated with different methods of assessing OSD. The effect of preservatives on the ocular surface, with respect to glaucoma patients in particular, was also reviewed. Objective methods for assessing ocular surface health and disease include the Schirmer test, tear break-up time, fluorescein turnover, corneal and conjunctival staining, tear osmolarity, and vital dyes. These measures all have limitations in terms of their ability to grade the severity of OSD. Previous studies using the OSD Index showed a mild-to-moderate correlation to dry eye disease severity. Other scoring systems for dry eye have shown a relationship to patient symptom scores or quality of life. Due to the challenges clinicians face concerning both subjective and objective ocular surface health assessments, discerning clinical improvement in ocular surface disease can be a challenge. Further research is needed in order to optimize existing clinical methods and/or identify alternative techniques for assessing OSD in the glaucoma population.
