New Possibilities of Tear Replacement Therapy in Patients with Dry Eye Syndrome of Various Origins

The artificial tears on the basis hyaluronic acid is primary importance today in dry eye syndrome (DES) treatment. In recent years, they have been supplemented Optinol® Express Moisture (0.21 %) and Optinol® Deep Moisture (0.4 %) differing concentrations of sodium hyaluronate and viscosity. The study is devoted to assessing the effectiveness of these drugs in the treatment of patients with dry eye syndrome (DES) of various etiology and severities.There were 73 volunteers with DES of various etiology: 21 — Sjogren’s syndrome, 24 — meibomian blepharitis, and 28 — perimenopause in the study. All patients were divided into 2 groups: 36 patients of the first group received instillations into conjunctival cavity of the Optinol® Express Moisture (0.21 %) and 37 patients of the second group — Optinol® Deep moistening (0.4 %).Starting from the first days of therapy, all patients had a decrease in the severity of subjective signs of DES, estimated by the value of the ocular surface disease index (OSDI). At the same time, tendency to stop of the degenerative changes in the epithelium of the ocular surface was established. It is characterized by a decrease in the degree of staining. The increasement of the tear film stability and an index of the tear meniscus was found in all patients. The dynamics of the controlled parameters increased, as the instillation of the drugs took place and by the 30th day of therapy. There were significant differences from the baseline values. At the same time, the Optinol® Express Moisture (0.21 %) was more effective (mainly in terms of subjective discomfort and the severity of degenerative changes in the epithelium of the ocular surface) in patients with mild and extremely severe form of the xerosis process.The drug Optinol® Deep Moisture (0.4 %) was more effective in patients with xerosis of moderate severity and severe by the same parameters. In the course of research, we have not observed any side effects of both drugs. It allows us to recommend the drugs Optinol® Express Moisture (0.21 %) and Optinol® Deep Moisture (0.4 %) to widespread clinical use in treating patients with DES of various etiology.

The aim of the study was to evaluate the effectiveness of the preparations Optinol® Express Moisture (0.21 %) and Optinol® Deep Moisture (0.4 %) in the treatment of children with dry eye syndrome (DES) and to determine the indications for prescribing these drugs for various etiologies and clinical course of the disease.Patients and methods. The study involved 56 children aged 4–17 years with DES, which were divided into 3 groups, depending on its pathogenetic type. The first consisted of 24 children with DES, which developed on the basis of chronic blepharitis, the second — 12 children with neuroparalytic keratitis, and the third — 18 children with chronic uveitis, in whom DES was caused by prolonged instillations of eye drops with benzalkonium chloride. Each group was divided into 2 more equal subgroups, the first of which was prescribed the drug Optinol® Express Moisture, and the second — Optinol® Deep Moisture with a frequency of 4 times a day.Results. In all children, from the very first days of instillation of the studied drugs, a decrease in the severity of subjective signs of DES (OSDI) was noted, as well as a gradual decrease in the degree of xerotic changes in the ocular surface (severity of its staining with vital dyes) and an increase in the stability of the tear film (M.Norn). At the same time, the positive dynamics of the controlled parameters increased with the continuation of therapy, reaching a maximum by the 30th day of treatment. Moreover, the effectiveness of therapy depended on the severity of xerosis of the ocular surface: it was maximal in children with mild, and minimal in children with an extremely severe form of xerosis (with neuroparalytic keratitis). Moreover, the drug Optinol® Express Moisture was more effective in the treatment of children with mild and extremely severe forms of DES, and Optinol® Deep Moisture — with moderate and severe xerosis.Conclusion. The preparations Optinol® Express Moisture and Optinol® Deep Moisturization are effective in the treatment of children with DES, which has developed on the basis of pathology of the ocular surface of neurotrophic and artifact genesis, as well as increased volatility of the precorneal tear film against the background of chronic blepharitis.

Introduction: Dry eye syndrome [DES] is one of the commonest ocular disorders characterized by tear film instability, visual discomfort & disturbance with ocular surface inflammation potentially leading to damage to the ocular surface. Serum Vitamin-D deficiency has been reported to be associated with DES. Aim: To determine the Serum 25-hydroxy-vitamin-D levels in patients diagnosed as having DES. Methods: We conducted a prospective observational study and included in our study, serum vitamin D levels of the first 40 patients over the age of 18 years presenting with signs and symptoms and later diagnosed to have DES [confirmed with ocular surface disease index-OSDI questionnaire, Schirmer I test, kerato-epitheliopathy examination and tear-film breakup time-[TBUT] were analysed. Results: Schirmer's I test, interpreted as mild [11-15mm/5min], moderate [6-10 mm/5 min] and severe [<5mm/5min] had 8, 17 and 15 patients, respectively, with a mean value of 8 mm/5 min Schirmers I test. The minimum and maximum of Fluorescein TBUT measured in seconds was 4 and 10 seconds, respectively, with a mean of 6.2 seconds. Twenty four of our test subjects were found to have deficient Serum Vit 25[OH] D levels, nine had insufficient levels and seven had normal levels. Conclusion: Vitamin D deficiency is prevalent in patient having DES.

Tear Film Stability

Aim: to study the changes in the critical parameters of tear film stability and autorefractometry in patients with mild dry eye syndrome (DES) after instilling artificial tear products of different viscosity. Patients and Methods: thirty patients aged 23–70 with mild bilateral DES were examined using the Visionix VX120+Dry Eye multi-diagnostic unit equipped with the TF-Scan to fix and assess tear film stability and tear breakup time (TBUT). The critical refraction and tear film parameters were evaluated by keratometry, corneal topography, TBUT, and tear meniscus height measurements. Next, an artificial tear product was instilled, i.e., group 1 (14 patients, 28 eyes) received a 0.15% sodium hyaluronate-based preparation, and group 2 (16 patients, 32 eyes) received a 0.4% sodium hyaluronate-based preparation. The examination was repeated after 30 sec and 5 min. Controls were seven healthy individuals (14 eyes). Results: in DES, breaks in the tear film appeared earlier and affected greater corneal surface area. A "Destabilized tear film area" parameter of the Visionix VX120+Dry Eye contributed significantly to the knowledge of tear film functionality, thereby empowering the diagnostic armamentarium in DES. As early as 30 sec after instillation of both artificial tear preparations, breakup-free time tended to increase, while the area of tear film destabilization tended to reduce. After 5 min, this trend continued to increase, particularly after instilling 0.15% sodium hyaluronate-based preparation. At the same time, changes in keratometry readings (i.e., sphere and cylinder) and astigmatism axis orientation were reported. Corneal refractive power (more in the flattest axis) increased, in particular, after the instillations of 0.15% hyaluronic acid. The range of changes was 0.00–0.75 D for the sphere power, 0.00–0.50 D for the cylinder power, and 0–69 degrees for astigmatism axis orientation. Conclusions: our findings with the Visionix VX120+Dry Eye multi-diagnostic unit demonstrate a significant variation of autorefractometry readings in DES depending on the extent of ocular surface hydration. These phenomena raise questions about the accuracy of autorefractometry readings. Therefore, autorefractometry should be performed after normalizing tear film volume and stability.

ABSTRACT This study aimed to evaluate the effect of the 0.15% sodium hyaluronate (SH) and of 0.5% carboxymethylcellulose (CMC) on tear film breakup time (TFBUT) in 10 healthy dogs and in 32 eyes of dogs with keratoconjunctivis sicca (KCS). In addition, the goblet cell density (GCD) of this population was quantified. TFBUT was assessed at baseline and at different time points following the instillation of SH and CMC. KCS was graded as mild, moderate, and severe. GCD were quantified from conjunctival biopsies. The number of GCD differed significantly between patients with mild and moderate KCS (P<0.01). TFBUT of healthy dogs increased only for 1 minute after treatment with SH (P<0.01). Regarding baseline and treatments, SH significantly increased TFBUT for up to 30 minutes on the ocular surface, in comparison to CMC, in all categories of KCS (P<0.01). TFBUT and GCD correlated positively when the healthy and diseased eyes were grouped (r=0.41, P=0.006). It can be concluded that in dogs with KCS, SH lasts longer periods on the ocular surface than CMC, but such agents does not increase TFBUT in healthy dogs. Additionally, tear film stability tends to reduce in a linear fashion from the mild to severe form of KCS.

Purpose To verify the presence of dry eye syndrome (DES) in treated patients with glaucoma and to analyze DES's impact on the patients' quality of life (QOL) versus the control group. Methods In this observational cross-sectional study, 61 patients were enrolled at a clinical practice. Patients were divided into three groups by number of glaucoma drops instilled per day (G1=1 drop/day, G2=2 drops/day, G3=3 drops/day). A control group of 20 subjects was also selected (G0). All subjects were submitted to a complete ocular examination (including tear function and ocular surface status) and completed the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ), Glaucoma Symptom Scale (GSS) questionnaire, and Ocular Surface Disease Index (OSDI). DES was defined as presence of punctate keratitis and decreased break-up time. Statistical analysis was performed applying the Kruskal-Wallis analysis of variance and Mann-Whitney U tests (to compare median values between groups) as well as the χ2 and Fisher test (to verify significant differences). Results A total of 40% of G3 and 39% of G2 patients presented DES versus 11% of G1 and 5% of G0 (p=0.01). QOL was significantly influenced and altered (NEI-VFQ 25 total mean and GSS total mean and symptoms average: p=0.0085, p=0.006, and p=0.03, respectively). OSDI pointed out differences by group: 26% of G2 and 15% of G3 presented moderate OSDI and 15% of G3 and 8.7% of G2 severe OSDI (p>0.05). Conclusions Patients with topically treated glaucoma present DES more often than a similar control group (p=0.01). The presence of DES negatively influences the patient's QOL. The patients with glaucoma's ocular surface status should be evaluated regularly to ensure the timely detection and treatment of pathologic signs on the ocular surface.
