Purpose: To analyze the relation between Meibomian gland dysfunction, dry eye, and sarcoidosis. Materials and Methods: Twenty eyes of 10 sarcoidosis patients (Group 1) and 20 left eyes of 20 age-sex matched healthy volunteers (Group 2) were included. Presence of dry eye was evaluated with Schirmer 1 test, tear film break-up time (T-BUT), Oxford scale scoring, Ocular Surface Disease Index (OSDI) score assessments. A slit-lamp biomicroscope infrared filter (Topcon, SL-D701, IJssel, The Netherlands) was used to evaluate Meibomian glands. The drop-out ratio according to meibography was scored for each eyelid from grade 0 (no loss) through grade 3 (lost area >2/3 of the total Meibomian gland area). Results: Among dry eye tests mean Schirmer 1 and T-BUT values were lower and OSDI score was higher in Group 1 compared to Group 2 and the differences were statistically significant ( p = 0.017, p = 0.039, p = 0.003, respectively). In addition, the upper, lower and total meiboscores were statistically significantly higher in Group 1 ( p = 0.047, p = 0.003, p = 0.005, respectively). Conclusion: A significantly higher presence of dry eye and Meibomian gland drop out ratios was detected in sarcoidosis patients. It is important to monitor sarcoidosis patients for dry eye and Meibomian gland dysfunction and when detected, to treat adequately to prevent ocular surface damage.

Purpose To investigate the comparative efficacy of intense pulsed light (IPL) therapy alone with that of IPL plus meibomian gland expression (MGX) for meibomian gland dysfunction (MGD). Methods This is a prospective randomized crossover clinical trial. Sixty patients were enrolled and randomly assigned to two groups. All of patients underwent four treatment sessions in total, which were two weeks apart. Group 1 underwent two sessions of IPL therapy with MGX, as well as two sessions of IPL alone. Group 2 received two sessions of IPL therapy alone, and two sessions of IPL therapy with MGX. The following parameters were measured at baseline (BL), 2 weeks after the second treatment session (FU1), and 2 weeks after the fourth treatment session (FU2): tearfilm break-up time (BUT), Oxford grade for corneal staining, meibomian gland expressibility (MGE), meibum quality (MQ), and ocular surface disease index (OSDI). The separate effect of MGX on improvement of MGD parameters was evaluated using generalized estimating equation (GEE). Results The mean age of the participants was 57.52 ± 10.50 years. The BUT, Oxford grade, MGE, MQ, and OSDI of both groups improved significantly (from baseline) by the end of four treatment sessions (FU2 compared to BL; all p-values <0.05). The MGE and MQ significantly improved after the first and second treatment sessions (FU1 compare to BL; all p-values < 0.001). However, the improvement was not statistically significant after the third and fourth treatment sessions (FU2 compared to FU1; p-value of 0.388 for MGE and 0.645 for MQ in group 1, 0.333 for MGE and 0.333 for MQ in group 2). The IPL plus MGX therapy produced greater improvements in the BUT scores than did IPL therapy alone (p = 0.003 by GEE). In contrast, the Oxford grade, MGE, MQ, and OSDI were not influenced by the addition of MGX to IPL (p = 0.642, 0.663, 0.731, and 0.840, respectively by GEE). Conclusion IPL therapy effectively improves the subjective symptoms and objective ocular findings of MGD. MGX enhanced the improvement of BUT driven by IPL therapy. The meibomian gland function (MGE and MQ) recovers faster in response to IPL therapy than did the other parameters.

: Dry eye is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. It is accompanied by increased osmolarity of the tear film and inflammation of the ocular surface. Meibomian Gland Dysfunction (MGD) is an abnormality of the meibomian gland that blocks the secretion of lipids. Without sufficient lipid production, tears evaporate quickly causing Dry Eye.MGD is associated with multiple pathological mechanisms including inflammation, microbial factors and lipid deficiencies. Topical Cyclosporine A (CsA) 0.05% is a calcineurin inhibitor that reduces inflammation by specifically inhibiting T‑cell activity, which reduces ocular surface inflammation and improves tear film dynamics. This was a prospective observational study done on 100 patients at the Department of Ophthalmology Basaveshwar teaching and general hospital, on patients of dry eyes due to meibomian gland dysfunction. Patients who were diagnosed with dry eyes due to meibomian gland dysfunction were invited to take part in the study. Patients were divided randomly into two groups of 50 patients each. This study, was explained in detail to them. An informed consent was obtained. Patients fulfilling the inclusion criteria were listed.All OSDI scores (symptom intensity, frequency and aggravation) revealed decreasing patterns throughout the observation period in both the groups. In single analysis, the cyclosporine A 0.05% group showed a significant improvement for each score at 3 months (p &#60; 0.01, p = 0.01, p = 0.02, respectively). The mean TBUT after treatment in the group A (cyclosporine A group) increased to 12.36± 3.58(p&#60;0.001) seconds, and in the group B (Control group) the TBUT score increased to 11.01±3.06 seconds. After 3 Months, there was statistically significant improvement in the mean Schirmer’s scores in both the treatment groups, however improvement was significantly greater in Cyclosporine A group. Prior to the treatment in group A (Cyclosporine A) mean Lissamine staining score was 2.73±0.15 and post treatment it reduced to 1.32±0.15 which was statistically significant (P&#60;0.001). In group B (Control group) score before treatment was 2.46±0.15 and after treatment it reduced to 2.39±0.27 (p=0.11), not much difference was seen. : Findings from our study showed that there were significant improvements in the dry eye conditions due to defect in meibomian gland by treatment of topical Cyclosporine A 0.05% and sodium hyaluronate 0.1%.

Purpose. The aim of this study was to investigate the effect of overnight orthokeratology (OOK) on ocular surface and meibomian gland dysfunction in teenagers with myopia. Methods. A total of 59 subjects were recruited in this prospective study. The following tests were performed before and after 1, 3, 6, 12, and 24 months of OOK lens wear, including ocular surface disease index (OSDI) questionnaire, slit-lamp examination, and Keratograph 5M. Results. No infectious keratitis occurred during the study. OSDI scores increased gradually and reached the maximum at 6 months of OOK wear (P<0.001). The meniscus height was significantly increased at 1 and 3 months after the initiation of OOK (P=0.006, P=0.035). The corneal fluorescein staining at 1, 3, 6, 12, and 24 months after wearing OOK were all increased than the prewearing level with significant difference (P=0.014, P=0.036, P<0.001, P<0.001, and P=0.008, respectively). The first and the average tear film NIKBUT were all higher than the prewearing level, but there was no significant difference between every follow-up time points (P>0.05). The lid margin abnormalities were significantly increased (P=0.003, P=0.038, and P=0.015) at 6, 12, and 24 months after the initiation of OOK. There was no significant difference in the meibomian gland orifice scores at each follow-up time points compared to the prewearing level (P>0.05). The meibomian gland lipid secretion scores after wearing OOK were higher than those of the prewearing level, however, without statistically significant difference (P>0.05). No significant differences of the degree of difficulty of lipid excretions were detected after the initiation of OOK (P>0.05). There was no significant difference in meibomian gland dropout scores between all follow-up time points and the prewearing level (P=1.000). Conclusion. OOK increased the symptoms of dry eye and decreased the function of tear film by affecting the meniscus height and BUT. OOK did not affect the function of meibomian glands.Clinical Study registration number: ChiCTR18000185708.

This study evaluated to what extent tear film break-up time (TFBUT) could discriminate pathological scores for other clinical tests and explore the associations between them. Dry eye patients (n = 2094) were examined for ocular surface disease index (OSDI), tear film osmolarity (Osm), TFBUT, blink interval, ocular protection index (OPI), ocular surface staining (OSS), Schirmer I test, meibomian expressibility, meibomian quality, and meibomian gland dysfunction. The results were grouped into eight levels of break-up time (≤2, ≥3, ≤5, ≥6, ≤10, ≥11, ≤15, and ≥16) with or without sex stratification. Receiver-operating characteristic curve (ROC) analysis and Pearson’s correlation coefficients were used to study TFBUT’s discriminative power and the associations among the tests, respectively. Above and below each TFBUT’s cut-off, all of the parameters indicated significant difference between groups, except OSDI (cut-off 15 s) and Osm (cut-offs 5 s–15 s). At TFBUT cut-off of 2 s, sex difference could be detected for OSDI, Osm, and OSS. OPI presented the strongest discriminative power and association with TFBUT in sharp contrast to Osm, holding the poorest discriminative power with no significant correlation. The remaining parameters were within the poor to very poor categories, both with regard to discrimination and correlation. In conclusion, patients with lower TFBUT presented with more severe DED parameters at all four defined cut-off values.

Dry Eyes

Dry eyes is a common, chronic condition that has a prevalence of about 5- 50%.1 According to the Dry Eye Workshop II report (DEWS II report), published in 2017, the updated definition of Dry Eye Disease is, “a multifactorial disease of the ocular surface characterised by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and hyper-osmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles.” The Tear Film & Ocular Surface Society (TFOS) released their report on the international work on Meibomian Gland Dysfunction (MGD)2 in 2011, which defined MGD, classified it and considered it as the primary cause of dry eye disease worldwide. Previously dry eye disease was considered as an aqueous deficiency problem, but after this report by TFOS, there is a paradigm shift towards “not producing enough lipids to retain the tears that are being produced”. This has led to a huge impact on the treatment protocols which were previously focused on managing the sequelae and symptoms of dry eyes rather than targeting directly on the underlying cause, the MGD. It has now been accepted worldwide that dry eye occurs when the ocular surface system cannot adequately protect itself from the desiccating stress due to the lack of a healthy meibomian gland secretion. This article is mainly focussed on the Meibomian Gland Dysfunction, discussing the normal anatomy of the glands, how they are affected by disease, its implications on the ocular surface and finally, the various treatment strategies. Key words: Blepharitis, Dry eyes, Meibomian gland dysfunction, blepharospasm.

Purpose. This study aims to evaluate dry eye and ocular surface conditions of myopic teenagers by using questionnaire and clinical examinations.Methods. A total of 496 eyes from 248 myopic teenagers (7–18 years old) were studied. We administered Ocular Surface Disease Index (OSDI) questionnaire, slit-lamp examination, and Keratograph 5M. The patients were divided into 2 groups based on OSDI dry eye standard, and their ocular surfaces and meibomian gland conditions were evaluated.Results. The tear meniscus heights of the dry eye and normal groups were in normal range. Corneal fluorescein scores were significantly higher whereas noninvasive break-up time was dramatically shorter in the dry eye group than in the normal group. All three meibomian gland dysfunction parameters (i.e., meibomian gland orifice scores, meibomian gland secretion scores, and meibomian gland dropout scores) of the dry eye group were significantly higher than those of the normal group (P<0.0001).Conclusions. The prevalence of dry eye in myopic teenagers is 18.95%. Meibomian gland dysfunction plays an important role in dry eye in myopic teenagers. The Keratograph 5M appears to provide an effective noninvasive method for assessing ocular surface situation of myopic teenagers.

Purpose: To study the effects of xanthan gum eye drops on the ocular surface and conjunctival cytology of patients with mild-moderate dry eye. Methods: This prospective, double-masked, controlled trial included 30 patients (age > 60 and Ocular Surface Disease Index score >12 and <33), divided into two groups of 15 subjects and treated with 0.2% xanthan gum eye drops (group 1) or 0.5% carboxymethylcellulose (group 2) qid. After a run-in period with saline qid, patients were evaluated by Ocular Surface Disease Index questionnaire, clinical assessment, and impression cytology at baseline (T0) and after 1 month (T1). For impression cytology, cellularity, cell-to-cell contacts, nucleus/cytoplasm ratio, chromatin aspect, goblet cells distribution, keratinization, and the presence of inflammatory cells were considered. Parameters were scored from 0 (no alterations) to 3 (evident alterations). For statistical analysis, Student’s t-test, Wilcoxon rank-sum test, and Mann–Whitney U-test were used. Results: Clinically, after 1 month of treatment, group 1 showed an improvement of corneal stain (T0 = 1.1 ± 1.4; T1 = 0.5 ± 0.7; p = 0.03) and a reduction of Schirmer I test (T0 = 9.8 ± 6.1; T1 = 5.9 ± 4.1; p = 0.001). In group 2, no differences were found between T0 and T1 for all the clinical tests. For impression cytology, in group 1 cellularity (T0 = 0.6 ± 0.5; T1 = 0.3 ± 0.5; p = 0.05), chromatin aspect (T0 = 1.2 ± 0.4; T1 = 0.8 ± 0.5; p = 0.01), keratinization (T0 = 1 ± 0.7; T1 = 0.5 ± 0.5; p = 0.03), and total score (T0 = 5.8 ± 1.3; T1 = 3.6 ± 1.7; p = 0.003) were significantly ameliorated, while in group 2 only total score improved significantly (T0 = 5 ± 1.4; T1 = 4.3 ± 1.5; p = 0.01). The comparison between groups showed significant amelioration for keratinization in group 1 at T1 (p = 0.02). Conclusion: The treatment with xanthan gum, a molecule with anti-oxidant and mucoadhesive properties, ameliorated conjunctival epithelium of mild-moderate dry eye patients better than carboxymethylcellulose.

AIM: To evaluate the clinical efficacy of dietary supplement of high dose DHA omega-3 in dry eye with meibomian gland dysfunction (MGD). METHODS: Prospective randomized double-masked, placebo-controlled clinical trial was conducted in mild to moderate dry eye patients with MGD. Patients have no history of taking any dietary omega-3 supplements before 3mo. Patients were divided into two groups: 24 patients in the omega-3 group and 26 patients in the placebo group. The omega-3 group received two capsules of Easyeye Dry®, total containing 600 mg of EPA and 1640 mg of DHA, while the placebo group received two capsules containing 3000 mg of olive oil. All patients take two pills once a day. The examination of MGD scores, tear break-up time (TBUT), corneal staining test (NEI), strip meniscometry (SM tube), and ocular surface disease index (OSDI) scores were performed at baseline, after 4 and 8wk. RESULTS: A total of 50 patients were included. There were no differences in baseline characteristics between the two groups, such as age, sex, and other ocular examination findings. The TBUT, NEI, and OSDI scores significantly improved after 4 and 8wk in both groups. While after 8wk TBUT (6.00±1.62s vs 5.08±1.28s, P=0.034) and MGD score (7.2±1.8 vs 8.1±2.6, P=0.033) in the omega-3 group was more significantly improved than that of the placebo group. CONCLUSION: Dry eye with the MGD patient, a high dose of DHA omega-3 dietary supplement can improve TBUT and MGD score after 8wk, effective in stabilizing the tear film.

Purpose. This study aimed to evaluate the effects of excision on dry eye and meibomian gland dysfunction (MGD) in individuals with pterygium, before and after surgery. It also aimed to investigate how these effects correlate with the size and thickness of the pterygium. Subjects and Methods. 63 eyes from 63 patients with primary nasal pterygium and 45 eyes from 45 healthy volunteers without ocular pathologies were enrolled in this study. 63 eyes from 63 patients underwent pterygium surgery. ImageJ software was used to calculate the pterygium size based on images of the anterior segments. Anterior segment spectral domain optical coherence tomography (SD-OCT) was performed preoperatively to measure the thickness of the pterygium 1 mm anterior to the nasal scleral spur. The ocular surface disease index (OSDI), Schirmer I Test (SIT), and MGD grade were used to evaluate the eyes, and the eyes were imaged using the noninvasive keratograph average tear film breakup time (NIBUTav), tear meniscus height (TMH), meiboscore, and lipid layer grading tools of the Oculus® Keratograph 5M, preoperatively and at 1, 3, and 6 months postoperatively. Results. The OSDI, NIBUTav, lid margin abnormality, meiboscore, and lipid layer grading values differed significantly in the pterygium patients in comparison with the controls (p<0.01 for all scores). However, the SIT and TMH values were unchanged between the two groups (all p>0.05). Multivariate regression analysis demonstrated that the NIBUTav, meiboscore, and lipid layer grading score was significantly correlated with the pterygium parameters, such as size and thickness. The postoperative OSDI, NIBUTav, lid margin abnormality, and lipid layer grading values improved significantly (p<0.05 for all scores). The SIT, TMH, and meiboscore results did not differ significantly between the pre- and postoperative values (p>0.05). Among the conventional and automated indexes, at 1 month postoperatively, SIT and TMH were significantly correlated with the pterygium parameters, but no correlation was observed at 3 and 6 months postoperatively. The OSDI, NIBUTav, meiboscore, and lipid layer grading values at 1, 3, and 6 months postoperatively were significantly correlated with the pterygium parameters. Conclusion. Abnormal tear film and meibomian gland (MG) function improved following pterygium excision in the patients with primary pterygium, which was associated with uncomfortable ocular symptoms. Pterygium parameters, such as size and thickness, correlated with the dry eye and MGD indexes in patients pre- and postoperatively, potentially offering a novel strategy for clinical implementation of pterygium excision surgery.

AbstractTo investigate the prevalence of meibomian gland dysfunction (MGD) in patients presenting with subjective dry eye-related symptoms at their first-time consultation in a Norwegian specialized ocular surface clinic. Additionally, to explore the accuracy of the ocular surface disease index score (OSDI) as an extensively applied tool to assess the severity of dry eye symptoms and MGD diagnosis. Patients with subjective dry eye-related complaints (n = 900) attending the clinic for the first time, from 2012 to 2016, were included in the study. At the baseline, patients completed the OSDI questionnaire. Subsequently, objective clinical tests, including fluorescein break-up time (FBUT), Schirmer-I test, ocular surface staining (OSS), and meibomian gland function assessment using gland expressibility and meibum quality were performed. The association between MGD and its severity in relation to symptom severity defined by OSDI-score was examined. MGD was found in 93.8% of the study group. MGD prevalence was not significantly different between groups based on age (p = 0.302) or sex (p = 0.079). There was a significant association between severity of MGD and dry eye-related symptoms (p = 0.014). OSS was significantly higher in patients with severe symptoms (p = 0.031). Sensitivity and specificity of positive symptom-score (OSDI ≥ 13) for disclosing MGD were 85.5% and 30.4%, respectively. MGD was highly prevalent, not associated with age and sex. OSDI ≥ 13 had high sensitivity and high positive predictive value (PPV), but low specificity and negative predictive value (NPV) for disclosing MGD. This underscores the importance of meibomian gland assessment in patients with dry eye-related symptoms.
