Immunomodulatory Properties of Natural Extracts and Compounds Derived from Bidens pilosa L.: Literature Review. Pharmaceutics 2023; 15:pharmaceutics15051491. [PMID: 37242733 DOI: 10.3390/pharmaceutics15051491] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 04/29/2023] [Accepted: 05/03/2023] [Indexed: 05/28/2023] Open
Abstract
Bidens pilosa L. has been used in different parts of the world mainly to treat diseases associated with immune response disorders, such as autoimmunity, cancer, allergies, and infectious diseases. The medicinal properties of this plant are attributed to its chemical components. Nevertheless, there is little conclusive evidence that describes the immunomodulatory activity of this plant. In this review, a systematic search was carried out in the PubMed-NLM, EBSCO Host and BVS databases focused on the pre-clinical scientific evidence of the immunomodulatory properties of B. pilosa. A total of 314 articles were found and only 23 were selected. The results show that the compounds or extracts of Bidens modulate the immune cells. This activity was associated with the presence of phenolic compounds and flavonoids that control proliferation, oxidative stress, phagocytosis, and the production of cytokines of different cells. Most of the scientific information analyzed in this paper supports the potential use of B. pilosa mainly as an anti-inflammatory, antioxidant, antitumoral, antidiabetic, and antimicrobial immune response modulator. It is necessary that this biological activity be corroborated through the design of specialized clinical trials that demonstrate the effectiveness in the treatment of autoimmune diseases, chronic inflammation, and infectious diseases. Until now there has only been one clinical trial in phase I and II associated with the anti-inflammatory activity of Bidens in mucositis.

Abstract
BACKGROUND The prevalence of dry eye, which is a common lacrimal disease, is steadily increasing in modern society. However, fundamental treatment for it has not yet been established. This study aims to assess the efficacy and safety of a novel medical device, the biodegradable microneedle acupuncture (BMA), using a traditional intradermal acupuncture needle as the control acupuncture for dry eye. METHOD This study will be an investigator-initiated, assessor-blinded, comparative, superiority pilot randomized controlled trial. A total of 30 patients with dry eye will be randomly assigned to the experimental or the control group in equal proportion. For the experimental group, the BMA will be applied to both sides of 5 acupoints including BL2, GB14, TE23, EX-HN5, and ST1. For the control group, conventional intradermal acupuncture will be applied to the same acupoints. The needles will be attached for 4 hours. Over 4 weeks, both the interventions will be performed 12 times in total. The primary outcome would be the ocular surface disease index. The secondary outcomes would be the visual analog scale for subjective symptoms, quality of life, Schirmer I test, and general assessment. DISCUSSION The findings of this study on the efficacy and safety of the BMA would be helpful for patients with dry eye in clinical practice. Further, these results would provide for the foundation of a large-scale BMA study.

The effects of systemic aromatase inhibitors on meibomian glands and corneal structure. Eye (Lond) 2022; 36:1185-1193. [PMID: 34117393 PMCID: PMC9151770 DOI: 10.1038/s41433-021-01612-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 05/14/2021] [Accepted: 05/18/2021] [Indexed: 11/08/2022] Open
Abstract
OBJECTIVES To evaluate the ocular surface, meibomian glands and corneal structural changes using in vivo confocal microscopy (IVCM) in patients receiving aromatase inhibitor (AI) therapy due to the breast cancer. METHODS This prospective observational study included 13 patients undergoing AI therapy. The patients were evaluated before the treatment, at 3- and 6-month timepoints of AI therapy. To examine the ocular surface and tear film, corneal sensitivity (CS) measurement with Cochet-Bonnet Aesthesiometer, tear film break-up time (TBUT), lissamine green (LG) staining, Schirmer I test with anaesthesia (ST) and the ocular-surface disease index (OSDI) questionnaire were performed consecutively. Corneal cell densities and sub-basal nerve plexus were evaluated with IVCM (ConfoScan 4, Nidek, Japan). Finally, quantitative MG drop-out assessment was made using infrared meibography. Shapiro Wilk, Friedman's and Post-hoc Dunn tests were used for the statistical analysis. RESULTS TBUT, ST scores, basal epithelium, anterior and posterior keratocytes and endothelial cell densities, long and total sub-basal nerve densities were found to be decreased (p < 0.001, p = 0.023, p < 0.001, p = 0.01, p = 0.002, p = 0.004, p < 0.001, p < 0.001), and meiboscore, CS, OSDI scores and sub-basal nerve tortuosity values were increased (p < 0.001, p = 0.015, p = 0.001, p = 0.004) during the treatment. Endothelial pleomorphism rates were lower at the 3- and 6-month timepoints compared to before the treatment (p = 0.04). CONCLUSION This study showed that aromatase inhibitor therapy causes deteriorations in many of the ocular-surface parameters and corneal structural changes in relation with the duration of treatment. These patients should be observed during the therapy in terms of the ocular-surface side effects.

Abstract
Purpose: To study the efficiency of vitamin D3 (buccal spray) alone and combination of vitamin D3 with cyclosporine in the treatment of dry eye disease (DED) in patients with deficient serum 25(OH)D levels. Methods: Around 90 patients with DED with deficient serum 25(OH)D levels were included and randomized into three groups and were given treatment for dry eye (Group A- 0.5% carboxymethylcellulose (CMC), Group B- 0.5% CMC + 2000 IU vitamin D through buccal spray, Group C- 0.5% CMC + 2000 IU vitamin D through buccal spray + 0.05% cyclosporine). The patients were followed at day-15, day-30, and day-90 for improvement in tear breakup time (TBUT) and Schirmer’s, and ocular surface disease index (OSDI) score. Improvement in serum vitamin D level was assessed at day-90. One way ANOVA test, paired t-test, and Chi-square test were used for analysis. Results: Group B and Group C had significantly higher in Schirmer’s test-I values as compared to Group A (P = 0.001, P < 0.001, P < 0.001 at day-15, day-30, and day-90, respectively). Significantly higher values of TBUT and mean serum vitamin D levels were obtained in Group B and Group C as compared to Group A at day-90 (P < 0.05). OSDI scores of patients significantly decreased in all three groups at all follow-up visits (P < 0.05). Overall, Group C and Group B were found statistically better than Group A. Group C showed better results than Group B but they were nonsignificant. Conclusion: Vitamin D supplementation leads to earlier and significant improvement in TBUT, Schirmer’s, and OSDI score in patients with vitamin D deficient DED.

Abstract
PURPOSE To evaluate the efficacy and safety of cyclosporine nanoemulsion 0.05% compared to cyclosporine emulsion 0.05% and diquafosol sodium 3%. METHODS This was a multicenter, randomized, evaluator-masked, active control, parallel, phase IV study. A total of 227 patients were randomly allocated to instill cyclosporine nanoemulsion 0.05% (CN) twice daily, cyclosporine emulsion 0.05% (CE) twice daily, or diquafosol sodium 3% (DQ) six times daily. Non-inferiority of CN was analyzed by primary endpoint (cornea and conjunctival staining scores at week 12). The secondary endpoints were scores of corneal staining, conjunctival staining, tear break-up time, Schirmer test, and Ocular Surface Disease Index at weeks 4 and 12. RESULTS Primary endpoints showed statistically significant improvements in all groups. Primary endpoints were -6.60 for the CN group, -5.28 for the CE group, and -6.63 for the DQ group (National Eye Institute scale from 0 to 33), verifying the non-inferiority of CN compared to CE (95% confidence interval, -0.15 to 2.80, Δ>-2.88). In intergroup comparison between CN and CE groups, the CN group had significantly more decreased conjunctival staining score at week 12. Intergroup comparison between CN and DQ groups showed consistent statistically significant improvements in TBUT and Schirmer test in the CN group. In the DQ group, TBUT showed late statistically significant improvement at week 12 and Schirmer test showed relatively short-term statistically significant improvement at week 4. CONCLUSIONS Cyclosporine nanoemulsion 0.05% was equivalently efficient compared to cyclosporine emulsion 0.05% and diquafosol sodium 3%. In addition, CN showed significant improvements in several parameters for treatment of dry eyes.

Abstract
To understand the pathophysiology of dry eye disease (DED), it is necessary to characterize proteins in the ocular surface fluids, including tear fluid (TF) and lacrimal fluid (LF). There have been several reports of TF proteomes, but few proteomic studies have examined LF secreted from the lacrimal gland (LG). Therefore, we characterized the proteins constituting TF and LF by liquid chromatography mass spectrometry. TF and LF were collected from patients with non-Sjögren syndrome DED and from healthy subjects. Through protein profiling and label-free quantification, 1165 proteins from TF and 1448 from LF were identified. In total, 849 proteins were present in both TF and LF. Next, candidate biomarkers were verified using the multiple reaction monitoring assay in both TF and LF of 17 DED patients and 17 healthy controls. As a result, 16 marker proteins were identified (fold-change > 1.5, p-value < 0.05), of which 3 were upregulated in TF and 8 up- and 5 down-regulated in LF. In conclusion, this study revealed novel DED markers originating from the LG and tears by in-depth proteomic analysis and comparison of TF and LF proteins.

Abstract
Dry eye is a common eye disease, and suitable animal models are indispensable for investigating the pathogenesis and developing treatments for dry eye. The present study was conducted to develop an androgen deficiency dry eye model induced by finasteride, and to evaluate ocular surface status and inflammatory cytokine gene expression in the lacrimal gland using a cytokine antibody array system. The results revealed that the antiandrogenic drug finasteride induced significant tear deficiency, and the histopathology results revealed significant inflammatory cell infiltration in the lacrimal gland. The cytokine antibody array system identified increased B7-2 (also known as cluster of differentiation 86), interleukin (IL)-1β, IL-4, IL-6, IL-10, matrix metalloproteinase-8, Fas ligand, tumor necrosis factor (TNF)-α and metalloproteinase inhibitor 1 levels in the lacrimal gland of the dry eye model. These cytokines were validated as candidate markers through the use of western blot analysis and reverse transcription-quantitative polymerase chain reaction. Both analyses confirmed a significant increase in proinflammatory cytokines, including IL-1β, IL-6 and TNF-α, and anti-inflammatory cytokines, including IL-4 and IL-10. The aforementioned data suggested that inflammation in antiandrogenic models resulted from a balance between inflammatory and anti-inflammatory responses. Thus, direct finasteride administration may produce an applicable model for dry eye mediated by androgen deficiency. In addition, there may be a correlation between sex, steroid deficiency and the inflammatory response. The findings of the present study have provided useful information for the pathogenesis and diagnosis of dry eye mediated by androgen deficiency.

Abstract
Keratoconjunctivitis sicca (KCS) is a dysfunction in tear production associated with clinical signs, which include conjunctival hyperemia, ocular discharge, discomfort, pain, and, eventually, corneal vascularization and pigmentation. Immunosuppressive drugs are routinely administrated for long periods to treat KCS but with side effects and limited results. Evaluation of the clinical benefits of intralacrimal transplantation of allogeneic mesenchymal stem cells (MSCs) in dogs with mild-moderate and severe KCS was done. A total of 24 eyes with KCS from 15 dogs of different breeds were enrolled in the present study. A single transplantation of MSCs (1 × 106) directly into lacrimal glands (dorsal and third eyelid) was performed. The Schirmer tear tests (STTs) and ocular surface improvements were used to assess short- and long-term effects of these cells. The STTs were carried out on day 0 (before MSCs transplantation) and on days 7, 14, 21, and 28, as well as 6 and 12 months after MSC transplantation. Our data demonstrate that allogeneic MSC transplantation in KCS dogs is safe since no adverse effects were observed immediately after transplantation and in short- and long-term follow-ups. A statistically significant increase in the STT and ocular surface improvements was found in all eyes studied. In all the eyes with mild-moderate KCS, STT values reverted to those of healthy eyes, while in eyes with severe KCS, although complete reversion was not found, there was improvement in tear production and in other clinical signs. Our study shows that a single dose of a low number of MSCs can be used to treat KCS in dogs. In contrast to immunosuppressive drug use, MSC transplantation has an effect over a long period (up to 12 months), even after a single administration, and does not require daily drug administration.

Abstract
Purpose: To assess the comorbidity of dry eye syndrome (DES) and changes in corneal curvature in children with allergies. Materials and Methods: This prospective, comparative, and observational interventional study included 49 patients, who presented to the Ophthalmology Clinic of a State Hospital in Turkey. There were 25 patients with clinically diagnosed seasonal allergic conjunctivitis (AC) (with complaints of itching and papilla formation of conjunctiva; AC group) and 24 healthy children (control group). There with no significant differences in age between groups. Using the ocular surface disease index (OSDI) questionnaire, we performed tear film break-up time (BUT), central reflex tear meniscus height (TMH-R) measurement, Schirmer test on both groups and evaluated keratometry (K1, K2) and spherical equivalent (SE). Results: Patients ranged in age from 6 to 18 years (median age, 11.79 years; 46.9% male; 53.1% female). The papillary reaction was severe in 10% of patients with AC. The prevalence of dry eye in children with AC was 12%. There was no statistically significant difference between groups for K1, K2, and SE (P > 0.05, all comparisons). BUT was statistically different (P = 0.004) between groups, indicating that a higher OSDI the tear film BUT was lower (ρ = 0.567). Statistically, significant negative moderate correlations were found between papillary reaction and the Schirmer test, BUT, and TMH-R (ρ = 0.454, −0.412, −0.419, and P = 0.001, 0.003, 0.002, respectively) Conclusions: The evaluation of pediatric patients with AC requires further attention to ensure an adequate diagnosis of DES.

Abstract
OBJECTIVES Our objective was to investigate the hypothesis that women on adjuvant aromatase inhibitors (AIs) for treatment of breast cancer have a higher prevalence of dry eye syndrome (DES) compared with controls. MATERIALS AND METHODS Exposure and control groups were recruited. A cross sectional questionnaire-based study was performed. Demographic data and medical histories were collected. The presence of dry eye syndrome was determined by the ocular surface disease index (OSDI). The Functional Assessment of Cancer Treatment - Endocrine Subscale (FACT-ES) was performed to investigate correlations with other side effects of AIs. RESULTS 93 exposure group and 100 control group questionnaires were included. The groups were similar in all demographic variables. The prevalence of dry eye syndrome was 35% (exposure) and 18% (control) (p < 0.01, OR 2.5). AIs were the only factor associated with dry eyes. The OSDI score was negatively correlated with the total FACT-ES score and positively correlated with duration of treatment. CONCLUSION Our study is the first to use a validated questionnaire to assess for DES in this population. DES is significantly more prevalent in women on AIs compared with controls. This is a newly emerging, and easily treated side effect of AIs. Self-reporting of dry eye symptoms underestimates the prevalence of DES with AIs. We recommend routine screening of patients on AIs with the OSDI with the aim of improving patient quality of life and possibly adherence.

Abstract
PURPOSE To measure the correlation between subjective symptom score, conventional clinical tests, and Fourier-domain optical coherence tomography (FD-OCT) of lower tear meniscus parameters in patients with dry eye disease. METHODS Eighteen patients with dry eye disease requiring medical therapy and/or punctal occlusion were recruited for this prospective, nonrandomized, observational case series. Severity of symptoms of dry eye disease was assessed using the Indiana University Dry Eye Questionnaire 2002. Clinical assessments were completed using slit-lamp biomicroscopy, rose bengal dye staining, fluorescein tear breakup time (TBUT), and a 5-minute Schirmer test with topical anesthesia. The lower tear meniscus was imaged using an FD-OCT system with 5-μm axial resolution and measured manually by a masked grader using computer calipers. Correlation was assessed using Spearman correlation coefficient (ρ). RESULTS The mean (±SD) scaled symptom score was 58 ± 21, with a range of 0 to 100. Vital staining test averaged 1.7 ± 3.4, TBUT averaged 4.4 ± 1.8 seconds, and Schirmer tests averaged 10.2 ± 8.1 mm. As determined by optical coherence tomography, the meniscus height was 228 ± 153 μm, depth was 127 ± 79 μm, and cross-sectional area was 0.018 ± 0.021 mm. Optical coherence tomography meniscus area was negatively correlated with the symptom questionnaire score (P < 0.01) and positively correlated with Schirmer test results (P < 0.01). There was no significant correlation between symptom score and rose bengal staining, TBUT, or Schirmer test results (P > 0.01). CONCLUSIONS Lower tear meniscus measurement with FD-OCT is an objective noninvasive test that correlates well with symptoms of dry eye disease and the Schirmer test.

Abstract
PURPOSE To investigate the effect of DA-6034, 7-carboxymethyloxy-3',4',5-trimethoxy flavone, in experimentally-induced inflammatory dry eye in rabbit. In addition, to elucidate the mechanism of DA-6034, we evaluated the mitogen-activated protein kinase (MAPK) signaling pathway and transcriptional factor-kappa B (NF-kB) in corneal epithelial cells. METHODS Rabbit lacrimal glands were injected with the T-cell mitogen concanavalin A (Con A). DA-6034 was then administered topically four times a day for six days starting 24 hr after Con A injection. Tear volume, tear function, MMP-9 and inflammatory cytokine levels in the lacrimal glands, and histological evaluation were subsequently assessed. In in vitro study, phosphorylated MAPKs (c-Jun NH2-terminal kinase (JNK) and p38 MAPK) and NF-kB were detected by enzyme-linked immunosorbent assay (ELISA) using human corneal epithelial cells. RESULTS A single injection of Con A into the lacrimal glands induced a pronounced inflammatory response, caused elevated levels of MMP-9 and cytokines IL-8 and TGF-beta(1), and induced a decrease in tear volume and shortening of tear breakup time (TBUT). In this inflammation model of dry eye, DA-6034 clearly showed therapeutic efficacy by restoring tear function and inhibiting inflammatory responses after topical ocular application. Furthermore, DA-6034 attenuated the phosphorylation of JNK and p38 MAPK and inhibited NF-kB activation in a concentration-dependent manner in corneal epithelial cells. CONCLUSIONS These results suggest that DA-6034 has the therapeutic effect in rabbit lacrimal gland inflammation model of dry eye and might be a potential treatment option for acute dry eye syndrome.

Abstract
Cyclosporine has been used successfully as a systemic immunomodulator for more than two decades, and numerous studies have investigated its mechanisms of action. In 2003 an ophthalmic formulation, cyclosporine 0.05% ophthalmic emulsion, was approved by the FDA to treat dry eye disease. Topical cyclosporine emulsion has also been investigated for treatment of other ocular surface disorders that may have an immune-based inflammatory component. In these trials, cyclosporine 0.05% ophthalmic emulsion has shown efficacy for management of posterior blepharitis, ocular rosacea, post-LASIK dry eye, contact lens intolerance, atopic keratoconjunctivitis, graft-versus-host disease, and herpetic stromal keratitis. As these disorders are often refractory to other available treatments, ophthalmic cyclosporine is a welcome nontoxic adjunct or replacement to potentially toxic topical or systemic immunosuppressive therapies.

Abstract
PURPOSE Symptoms of dry eye are commonly reported in contact lens wearers and are a frequent cause of non-tolerance. The purpose of the present study is to evaluate the effects of oral treatment with particular omega-6 fatty acids in the form of evening primrose oil (EPO) on subjective symptoms, ocular surface signs and tear film characteristic in patients with contact lens associated dry eye. METHODS The study design was randomised, double-masked and placebo controlled. 76 female soft contact lens wearers were treated for 6 months with either EPO or placebo (olive oil). Subjects underwent three examinations (baseline, 3 and 6 months). At each examination subjects were given a questionnaire relating to lens comfort and dry eye symptoms and underwent a series of tests of tear film characteristics (tear meniscus height, break-up time), meibomian gland function (lipid layer thickness and quality) and ocular surface parameters (hyperaemia and staining). RESULTS The EPO group showed a significant improvement in the specific symptom of 'dryness' at 3 and 6 months (p<0.01) and also a significant improvement in overall lens comfort at 6 months (p<0.01). Tear meniscus height was increased in the EPO group at 6 months relative to baseline (p<0.01), although all other objective signs were unchanged. CONCLUSION This study provides evidence for a beneficial effect of particular orally administered omega-6 fatty acids in alleviating dry eye symptoms and improving overall lens comfort in patients suffering from contact lens associated dry eye.

Abstract
PURPOSE To develop a method to quantify tear protein concentration with the sensitivity to measure this variable in the restricted volumes of single human tear samples. METHODS Aliquots of tear fluid from healthy subjects and a solution of standard bovine serum albumin (BSA) were spotted on cellulose membranes. Membranes were fixed, stained for protein with Coomassie blue, and washed until they displayed clear backgrounds. Stained spots were excised and eluted in a defined volume of methanol-ammonia, and the absorbance was determined spectrophotometrically at 610 nm. Membranes were calibrated by calculating their apparent thickness from the areas of stained spots and the corresponding aliquot volumes of either tear fluid or BSA solution. RESULTS In our dye-binding assay, absorbance (0-1.00 OD) was found to have a linear relation with tear fluid volume (1-7 microL). In a study involving samples from 33 healthy subjects, aliquots (3 microL) of tear fluid were found to yield absorbances in the linear range. Protein concentrations in tear fluid were found to be distributed over the range of 2.20-6.37 mg/mL (mean, 4.11 +/- 1.00 mg/mL) with no apparent sex differences. The assay can be applied successfully to quantify protein concentrations in tear fluid by using calibrated Schirmer strips after a tear test. Electrophoretic profiles of proteins present in tear fluid sampled from different healthy individuals were nearly identical when normalized for protein load by using this method. CONCLUSIONS The protein dye-binding assay we developed by using cellulose membranes or Schirmer strips is an efficient and convenient method for measuring tear protein concentration.

Abstract
Ocular allergy, with a significant increase of prevalence, is one of the most usual disease of the ocular surface. But, in a same entity, it means different kinds of clinical diseases with acute hayfever conjunctivitis, usually easy to diagnose, but also chronic perennial forms without any functional or clinical specificity among others ocular surface diseases. These clinical aspects are underlain by complex cellular mecanisms which are essentially located inside the conjunctiva. Initially, allergen cross the lacrimal tear film, the first natural barrier of the eye, then in the conjunctival epithelium, meet the antigen presenting cells, the Langerhans cells, lymphocytes and all the others components of the inflammatory and allergic reaction, including mast cells and eosinophils. The cornea could also be involved in allergic diseases, mostly in severe ones such as vernal or atopic keratoconjunctivitis, but most often, its pathology is due to direct cytotoxic effect of chemical mediators, such as eosinophil proteins, rarely results from mechanical or immunological pathways.

Abstract
PURPOSE To evaluate the effect of hormone replacement therapy (HRT) on dry eye in post-menopausal women. METHODS Forty post-menopausal women with dry eye (20 patients, group 1) and without dry eye (20 patients, group 2), and planning to receive HRT (estrogen plus progesterone), were recruited as the study groups. Forty age-matched untreated women were enrolled as controls (group 3 with dry eye, 5 patients; group 4 without dry eye, 35 patients). Patients having at least one of the symptoms (dryness, itching, photophobia, foreign body sensation, and tearing) together with two of the tests with positive results for dry eye (tear film break-up time (BUT), fluorescein staining of the cornea, analysis of the meibomian gland, and Schirmer I test) in both eyes were considered dry eye positive. Hormonal assay for follicle stimulating hormone, luteinizing hormone, estradiol, and free testosterone was performed. Dry eye statuses in the groups were evaluated statistically. RESULTS Four patients with incomplete follow-up data were excluded. HRT use increased estradiol levels in the groups. Mean ages of patients (50.2+/-4.8 and 50.7+/-3.9 years, and 50.0+/-4.6 and 53.0+/-3.9 years) were similar (p=0.67). Duration of menopause in groups 1 and 2 (3.2+/-2.2 and 1.4+/-1.2 years; p=0.01), and in groups 3 and 4 (3.0+/-1.6 and 1.7+/-1.3 years; p=0.014) were different. At the third month examinations, all of the patients in group 1, and 11 patients (61.1%) in group 2 had dry eye (p=0.003). CONCLUSION Duration of menopause and use of HRT may increase the incidence of dry eye in post-menopausal woman.

Abstract
The use of a contact lens as a polymeric delivery vehicle is presented. Specifically, the elution of nonfunctionalized poly (vinyl alcohol) (PVA) from nelfilcon A hydrogel lenses is presented as a model of delivering polymeric active agents to the eye. High molecular weight nonfunctionalized PVA is added to the lens matrix for later release into the tears. This is made possible by photo crosslinking a macromer species in lieu of monomeric polymerization. Consistent near zero order release of 0.062% (wt/wt) was demonstrated in vitro over a 20-h period. The result is a new contact lens device based on the slow release of PVA. In vivo results demonstrate that this product improves the wearing comfort of this type of contact lens and acts as a model basis for drug delivery.

Abstract
The therapy of dry eye disease as a chronic problem necessitates a long-term therapeutic association between patient and ophthalmologist. The aim of therapy is to relieve symptoms and improve vision as far as possible with an acceptable level of effort on the part of the patient. Therapy of dry eye follows a staged concept including tear replacement, serum eye drops, punctum plugs, novel anti-inflammatory drugs (cyclosporin A), and surgical procedures. Interdisciplinary care, especially of patients with autoimmune disease, is recommended and is best provided in a specialized dry eye outpatient clinic with quality control.
