Introduction: Given the increasing use of electronic devices, and the increasing number of complaints with its use, we intend to evaluate the prevalence of manifestations of dry eye and ocular fatigue in a population of individuals, who use the computer daily to perform all their professional tasks, as well as to correlate these complaints with the number of hours of digital use as well as their possible improvement with behavioural measures and use of tear drops.Material and Methods: A total of 77 individuals (154 eyes) were evaluated on two separate days with a 1-month interval. They completed two questionnaires: OSDI and PEG Eye Fatigue. An objective ocular surface assessment was performed: Schirmer test without anesthetic, DR-1a Dry Eye Monitor™, hyperemia evaluation, lacrimal break up, presence of keratitis and lesions in the conjunctiva, as well as near accommodation point and near convergence point. After the first evaluation, the subjects were divided into two groups: group A (< 2 hours of computer working) and group B (> 2 hours of computer working). Some environmental measures to reduce complaints and recommendation of use of artificial tears were explained to the latter.Results: There was a statistically significant difference in the majority of the parameters evaluated in the group B, in relation to the morning period (group A) - tear film (p = 0.032), hyperemia (p < 0.001), BUT (p < 0.001), keratitis (p < 0.001), conjunctival lesion (p = 0.002) and accommodation point (p < 0.001). In the evaluation – one month later - there were no statistically significant differences in any of the parameters analysed in the group A, and in group B there was a decrease in most parameters at the end of that period - Schirmer test (p = 0.005), lacrimal film (p = 0.022), keratitis (p < 0.001), conjunctival lesion (p = 0.005) and fatigue score (p < 0.001).Discussion: It was thus possible to show the appearance of ocular fatigue and ocular surface changes with prolonged use of computers (> 2 hours) as well as a significant improvement in symptomatology (subjective assessment) as well as of ocular surface changes (objective evaluation) with the implementation of postural measures, regular breaks and use of lubricants. This is the first study, to the best of our knowledge, of digital asthenopia in which, in addition to the subjective evaluation, the presence of ocular surface modifications (objective assessment) were evaluated and the respective improvement with the aforementioned ergophthalmological measures were evaluated.Conclusion: This survey highlights the increased overall level of awareness that we need to have to face the rapid and wide-scale changes driven by the emergence of digital technology and, more particularly, its impact on user’s vision and posture. We concluded that the longer we use the electronic devices (more than two hours) the more severe the complaints and rates of ocular surface changes are. Environmental and ocular strategies can attenuate or even eliminate the discomfort caused by this syndrome, and increase professional performance and quality of life.

: 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%.

Abstract Many studies have shown that gut microbial dysbiosis is a major factor in the etiology of autoimmune diseases but none have suggested that the ocular surface (OS) microbiome is associated with Sjögren’s syndrome (SS). In this prospective study, we analyzed bacterial distribution on the OS in patients with primary SS. Among the 120 subjects included in this study, 48 patients (group A) had primary SS, whereas 72 subjects (group B) had dry eye symptoms that were unrelated to SS. We evaluated clinical dry eye parameters such as the OS disease index, ocular staining score, Schirmer’s test, and tear break-up time. Conjunctival swabs were used to analyze the microbial communities from the two groups. Bacterial 16S rRNA genes were sequenced using the Illumina MiSeq platform, and the data were analyzed using the QIIME 1.9.1 program. The Shannon index was significantly lower in group A than in group B microbiota. An analysis of similarity using the Bray–Curtis distance method found no difference in beta-diversity between the two groups. In group A, Actinobacteria at the phylum level and Corynebacteria at the genus level exhibited low abundance, but the differences were not statistically significant. SS apparently decreases the diversity of the OS microbial community and may affect the abundance of some bacterial strains at the phylum and genus levels. These observations may be important for the pathophysiology of SS and should be investigated in future studies.

Purpose To quantitatively evaluate the effects of 0.05% cyclosporine A (CsA) on lipid layer thickness (LLT) and meibomian glands after cataract surgery using the LipiView® ocular surface interferometer. Methods This study was a prospective randomized double-masked clinical trial conducted by Pusan National University Yangsan Hospital between April 04, 2019, and November 31, 2019. Sixty-two participants were recruited, and 12 of them were not enrolled because they had undergone previous treatments for ocular surface diseases. The participants were adult patients with cataract, exhibiting normal lid position; they did not present any other ocular disease and did not meet the exclusion criteria of the clinical trial. Fifty subjects were enrolled in the study. The randomized subjects received treatment with 0.05% CsA (group A) or 0.5% carboxymethyl cellulose (CMC) (group B) over the 3 months following the cataract surgery. Subjective and objective assessments were performed at preoperative and postoperative visits. Ocular Surface Disease Index (OSDI), tear breakup time (TBUT), and Schirmer’s I test were performed by the same surgeon, and LLT and meiboscore were determined using the LipiView® interferometer. Results Fifty subjects subjects enrolled consisted of men (50%) and women (50%), with a mean (SD) age of 65.94 (10.35) years. Four subjects in group A and five in group B were excluded from the analysis as they were lost to follow-up within 1 month after cataract surgery. Thus, the study comprised 41 eyes of 41 subjects; 21 subjects were treated with CsA and 20 subjects with CMC. Comparing the clinical measurements between groups A and B taken at the last visit, while controlling the effects of the preoperative values, TBUT and LLT showed significant differences (p = 0.035 and p = 0.047, respectively, by ANCOVA). The TBUT between the subjects using CsA and those using CMC after cataract surgery showed a significant difference during follow up (p = 0.003 by repeated measures ANOVA). In the multivariate analysis, preoperative LLT and the use of CsA were found to be independent parameters for postoperative LLT (R2 = 0.303; p = 0.008 and p = 0.045, respectively), whereas the follow-up duration exhibited a positive correlation with the difference between the preoperative and postoperative values of LLT in the group treated with CsA (R2 = 0.738 and p < 0.001). Conclusion Treatment with 0.05% CsA following cataract surgery is effective in improving TBUT and LLT in comparison with 0.5% CMC. A higher preoperative value of LLT and the postoperative use of CsA could be significant determinants of a higher postoperative LLT value. Trial registration ISRCTN registry with ISRCTN 10173448.

AIM: To observe the effect of different concentrations Buddleja offcinalis eye drops (BOED) to inflammatory factors of lacrimal gland cells of castrated male rabbit with dry eye. METHODS: Forty-two healthy adult New Zealand rabbits were randomly divided into 7 groups, 6 rabbits each group. Group A: blank group, Group B: model group, Group C: low concentrations BOED group, Group D: medium concentrations BOED, Group E: high concentrations BOED, Group F: the placebo group, Group G: testosterone groups. All rabbits of group B to G were cut off bilateral testis and epididymis except group A. The rabbits of group C, D, E and F were dropped relevant eye drops except groups A and B. All rabbits were tested Schimer I test (SIT) and break-up time (BUT) before operation and 4wk after operation. Expressions of inflammatory factors of TNF-α, IL-1β from lacrimal gland cells were checked in immunohistochemical staining method. RESULTS: 1) Comparison of SIT and BUT: Compared with the groups D, E and G, group C had statistical significance (P<0.01). Compared with group D and E, G groups, there was no significant difference among those group before and after operation (P>0.05); 2) Comparison of inflammatory factors of TNF-α, IL-1β after operation: Compared with value of the average optical density of TNF-α and IL-1β of group C, those of group D, E and G were obviously different after operation (P<0.05). Compared D and with E, G groups, there was no significant difference between those group after operation (P>0.05).

Objective:To evaluate the incidence of ocular surface disease (OSD) and to determine the effects of topical pressure-lowering drugs on ocular surface disease in primary angle closure patients.Methods:This was a cross-sectional comparative study comparing primary angle closure glaucoma (PACG) patients (Group A) with primary angle closure and primary angle closure suspect (Group B). Group A was treated with topical pressure-lowering drugs; Group B was not. Data on ocular diagnosis and details of treatment were obtained from medical records. Ocular surface disease incidence was assessed using the Ocular Surface Disease Index (OSDI) questionnaire and from clinical signs using Schirmer’s test, tear break-up time and corneal fluorescein stain. Predictive Analytic Software 20 and STATA analysis software were used for statistical analyses.Results:Group A demonstrated a higher rate of OSD (OSDI 52.3%, Schirmer’s test 70.5%, tear break-up time (TBUT) 75%, corneal staining 77.3%) compared to Group B (OSDI 39.0%, Schirmer’s test 73.2%, TBUT 58.5% and cornea staining 14.6%) except for Schirmer’s test. There was a significant difference in mean score of OSDI (p=0.004), TBUT (p=0.008) and cornea staining (p<0.001) between two groups. Primary angle closure glaucoma treated with more than two medications and for more than three years had worse ocular surface disease parameters but without statistical significant difference.Conclusion:Ocular surface disease is common in PACG patients treated with topical pressure-lowering drugs. Topical pressure-lowering drugs caused significant OSD symptoms and signs except for tear production in PACG patients. Thorough evaluation of ocular surface disease is important to ensure appropriate treatment and intervention in PACG patients.

Background: Functional tricuspid valve regurgitation secondary to left-sided valve disease is common. DeVega repair is simple, but residual regurgitation with subsequent impairment of the right ventricular function is a concern. This study aims to compare tricuspid valve repair using DeVega vs. ring annuloplasty and their impact on the right ventricle in the early postoperative period and after six months. Methods: This is a prospective cohort study of 51 patients with rheumatic heart disease who underwent tricuspid valve repair for secondary severe tricuspid regurgitation. Patients were divided into two groups: group A; DeVega repair (n=34) and group B; ring annuloplasty repair (n=17). Patients were assessed clinically and by echocardiography before discharge and after six months for the degree of tricuspid regurgitation, right ventricular diameter and tricuspid annular plane systolic excursion (TAPSE). Results: Preoperative echocardiographic assessment showed no difference in left ventricular end-systolic diameter, end-diastolic diameter, ejection fraction and right ventricular diameter, however; group A had significantly better preoperative right ventricular function measured by TAPSE (1.96 ± 0.27 vs1.75 ± 0.31 cm; p=0.02). Group B had significantly longer cardiopulmonary bypass time (127.65 ± 13.56 vs. 111.74 ± 18.74 minutes; p= 0.003) and ischemic time (99.06 ± 11.80 vs. 87.15 ± 16.01 minutes; p= 0.009). Pre-discharge, there was no statistically significant difference in the degree of tricuspid regurgitation, but the right ventricular diameter was significantly lower in group B (2.66 ± 0.41 and 2.40 ± 0.48 cm; p=0.049). After six months of follow up, the degree of tricuspid regurgitation (p= 0.029) and the right ventricular diameter were significantly lower in the ring annuloplasty group (2.56 ± 0.39 and 2.29 ± 0.44 cm; p=0.029). Although there was a statistically significant difference in preoperative TAPSE, this difference disappeared after six months. Conclusion: Both DeVega and ring annuloplasty techniques were effective in the early postoperative period, ring annuloplasty was associated with lesser residual regurgitation and better right ventricular remodeling in severe functional tricuspid regurgitation than DeVega procedure after 6-months of follow up.

Objective: To study the effect of short-term use of oral contraceptive pills on intra-ocular pressures of women of childbearing age.   Methods: It was a comparative observational study, conducted at Arif memorial teaching hospital and Allied hospital Faisalabad for a period of six months. Hundred female subjects were divided into two groups of 50 each. Group A, included females, who had been taking oral contraceptive pills (OCP) for more than 6 months and less than 36 months. Group B, included 50 age-matched controls, who had never used OCP. Ophthalmic and systemic history was taken. Careful Slit lamp examination was performed and intraocular pressures (IOP) were measured using Goldman Applanation tonometer. Fundus examination was done to rule out any posterior segment disease. After collection of data, we analyzed and compared the intra ocular pressures between the two groups by using ANOVA in SPSS version 21.   Results: Average duration of using OCP was 14.9 months. There was no significant difference of Cup to Disc ratios between the two groups (p= 0.109). However, significant difference was noted between the IOP of OCP group and controls. (p=0.000). Conclusion: OCP significantly increase IOP even when used for short time period.

Dushta Vrana is a common and frequently encountered problem faced in surgical practice. The presence of Dushta Vrana worsens the condition of the patient with different complications and may become fatal. Local factors on wound like slough, infection and foreign body, affect the normal process of healing. A healthy wound in a normal body heals earlier with a minimum scar as compared to a contaminated wound. Therefore in this study all the efforts are made to make a Dushta Vrana into a Shuddha Vrana. Once the Vrana becomes Shuddha, Ropana of the Vrana will start. The objective of the study was to evaluate the clinical efficacy of Jatyadi Taila and Jatyadi Ghrita in Dushta Vrana. Clinically diagnosed 60 Patients of Dushta Vrana were randomly divided into two groups, each consisting of 30 Patients. Group A were treated with the Jatyadi Taila and Group B was treated by Jatyadi Ghrita. The results observed was based on the relief obtained on the subjective and objective parameters taken for consideration for this study viz, size of ulcer, discharge, smell, pain, burning sensation, itching and granulation were found significant (P Lass Than 0.05). On the basis of assessment criteria and overall result of treatment, the patients of Jatyadi Taila group showed better results when compared to Jatyadi Ghrita group. Even though statistically there is no much significant difference between the two groups, but by seeing the effect on individual parameters (subjective and objective) and over all response, Jatyadi Taila seems to be effective when compared to Jatyadi Ghrita. It is having more Ropana qualities when compared to Shodhana.

The quest for excellence in mental and physical health is not new. We find various references and formulations in Ayurvedic classics meant for promoting mental and physical health of a child. Suvarna Prashan is one of the formulations explained in age old Ayurvedic classic Kashyap Samhita. This formulation is very widely used now days as a memory and immune booster for children. But there is very little systematic documented study which can be used to evaluate the efficacy of the formulation. Suvarna Bhasma was prepared in Ayurved Rasayani Pharmacy, Pune. Madhu and Ghrita were collected from KLE Ayurveda Pharmacy, Belgaum. Suvarna Bindu Prashan was prepared in KLE Ayurved pharmacy, Belgaum. It contains Suvarna Bhasma, Ghrita and Madhu. Twenty apparently healthy male and female children with age group of three to four years were ready to sign inform consent form were selected into two groups each. Subjects in Group A received Suvarna Bindu Prashan where as Group B (Control group) did not receive any treatment. Both the groups were observed for six months. Children in Suvarna Bindu Prashan group showed significant reduction in the scores of eating habits, behavior, mood, temperament and scores of event of illness. However there was no significant difference in the score of sleeping habit. There was significant increase in IQ percentage.

Abstract Background The quest for better patient outcomes is driving to the development of minimally invasive spine surgical techniques. There are several evidences on the use of microsurgical decompression surgery for degenerative lumbar spine stenosis; however, few of these studies compared their outcomes with the traditional laminectomy technique. Objectives The aim of our study was to compare outcomes following microsurgical decompression via unilateral laminotomy for bilateral decompression (ULBD) of the spinal canal to the standard open laminectomy for cases with lumbar spinal stenosis. Subjects and methods Cases were divided in two groups. Group (A) cases were operated by conventional full laminectomy; Group (B) cases were operated by (ULBD) technique. Results from both groups were compared regarding duration of surgery, blood loss, perioperative complication, and postoperative outcome and patient satisfaction. Results There was no statistically significant difference between both groups regarding the improvement of visual pain analogue, while improvement of neurogenic claudication outcome score was significant in group (B) than group (A). Seventy-three percent of group (A) cases and 80% of group (B) stated that surgery met their expectations and were satisfied from the outcome. Conclusion Comparing ULBD with traditional laminectomy showed the efficacy of the minimally invasive technique in obtaining good surgical outcome and patient satisfaction. There was no statistically significant difference between both groups regarding the occurrence of complications The ULBD technique was found to respect the posterior spinal integrity and musculature, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods than the open laminectomy technique.
