The prevalence of vitamin D deficiency ( 0.05). No significant differences in TF grades and PRT and TBUT scores were observed between pre- and post-vitamin D3 supplementation in healthy controls. For the study group, there were strong correlations between measurements of PRT (OD) and PRT (OS) and between TBUT (OD) and TBUT (OS) pre- and post-vitamin D3 supplementation. No correlation was found between TF (OD) and TF (OS) grades pre- and post-vitamin D3 supplementation. The TF test suggests that short-term oral vitamin D3 supplementation can improve the quality of tears in dry eye subjects. Oral vitamin D3 supplementation can be potentially used as an effective treatment for subjects with dry eye symptoms. Our study offers important insights into how vitamin D3 supplementation can improve tear film in dry eye patients and in turn improving patients’ quality of life. Future studies are needed to investigate the long-term effect of vitamin D3 supplementation on the stability of the tear film.","PeriodicalId":14184,"journal":{"name":"International Journal of Ophthalmology & Visual Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87274728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods: Retrospective study done in 404 eyes with primary pterygium. Excision of the pterygium and conjunctival autograft fixation using sutures (group 1) or Autologous blood (group 2). Graft related complications such as recurrence, graft loss, graft retraction, granuloma were noted and compared between the two groups. Result: The average time taken for surgery was 10.66 ± 0.89 (group 1) and 10.44 ± 0.77 (group 2) (p=0.009). The recurrence rate following pterygium surgery was noted in 5eyes (2.5%) in group 1, and 10 eyes (4.9%) in group 2. Graft retraction was seen in 13 eyes in group 1,57 eyes in group 2, of the eyes with graft retraction only 2 eyes in group 1, and 7 eyes in group 2 developed recurrence (p=0.763). Graft loss was seen in 3eyes (1.49%) and in 7eyes (3.44%) in group 2, all patients who developed graft loss developed graft recurrence. Granuloma formation was seen in 2 eyes (0.99%) in group 1 and in 1eye (0.49%) in group 2. The cost of pterygium surgery using glue and autologous blood for conjunctival autograft fixation is much less than procuring and using fibrin glue. Conclusion: Fixing of graft and suturing it in place is important to prevent recurrence. Duration of surgical procedure is comparable. Recurrence and retraction rates are slightly higher in autologous blood group, but not statistically significant. Hence both sutures and autologous blood are very good treatment options for our patients with primary pterygium.","PeriodicalId":14184,"journal":{"name":"International Journal of Ophthalmology & Visual Science","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91130066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The singularity of this report case is the uncommon mode of his discovery: isolated bilateral visual impairment. This clinical case challenges us and reminds the interest of the funduscopic examination during ophthalmological consultation, and teaches us that taking the blood pressure of a teenager who consults for an isolated bilateral decrease of vision is not without interest.

In addition, smokers are more likely to develop dry eye symptoms compared with nonsmokers. Purpose: To assess the tear evaporation rate in chronic smokers using a VapoMeter. Materials and Method: This observational, case-control and non-randomized study included one hundred and twenty male smokers that ranged in age from 18 to 43 years (mean ± SD = 25.4±5.8 years). An age (18-43 years) matching control group (120 male subjects), with a mean age of 26.1±5.2 years participated in the study. Each participant completed the ocular surface disease index dry eye questionnaire, then a VapoMeter was used to determine the tear evaporation rate. Result: Significant (Kolmogorov-Smirnov test; p<0.05) differences were found between the average scores collected from the ocular surface disease index and the tear evaporation rate measurements within the smokers and nonsmokers groups. The average tear evaporation rate was significantly (p<0.05) higher in the study group [median (interquartile range; IQR) = 37.7 (59.3) g/m2h] compared with that obtained in control group [15.4 (13.1) g/m2h]. Moreover, the average score from the ocular surface disease index in smokers was significantly (p<0.05) higher [15.4 (13.1)] compared with that obtained in the control group [5.4 (5.5)]. Conclusion: Smokers have significant higher tear evaporation rates compared with nonsmokers and normal eye subjects. Clearly, VapoMeter can be used as a reliable tool to assess the eye dryness due to excessive evaporation of tears. Smoking is a risk factor for cancer, heart diseases, and cataract. In addition, smoking is a risk factor for eye dryness and contributes to evaporative dry eye disease, more likely due to the disturbance in the non-polar lipid layer within the tear film. Lipid-rich eye drops could be used to manage dry eye symptoms in smoker subjects. Moreover, smoking cessation remains the single most effective prophylactic measure to avoid dry eye symptoms.","PeriodicalId":14184,"journal":{"name":"International Journal of Ophthalmology & Visual Science","volume":"102 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89154172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods and materials: Human primary pterygium or normal Tenon's capsule tissues were obtained from patients with primary pterygium following surgical excision or from normal human fresh cadaver eyes. The tissues were processed within 2 hours. The mRNA or protein specimens were extracted from those tissues for analysis, cryosections of those tissues were prepared for immunohistochemical staining. The mRNA levels of endoplasmic reticulum (ER) stress-related factors in those tissues were detected by qPCR analysis and the related proteins levels were detected by qPCR analysis and immunohistochemical staining or western blotting. Results: The ER stress-related gene transcription levels of GRP78，spliced XBP-1, ATF4 and ATF6 and the protein expression levels of GRP78, p-IRE1α, p-eIF2α and ATF6 were all increased in the human primary pterygium tissues when compared with the normal control tissues. Conclusion: The results in this study suggest that the three unfolded protein response pathways are all activated in the human primary pterygium tissues, which indicates that the ER stress is involved in the progression of pterygium, and also suggests a potential mechanism of ER stress-induced inflammation in the human primary pterygium tissues.","PeriodicalId":14184,"journal":{"name":"International Journal of Ophthalmology & Visual Science","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84578222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We wanted to demonstrate the approach differences between neurologists and ophthalmologists, and examine the role of early neuroimaging in managing acute ocular motor mononeuropathies. Methods: Retrospective chart review. Patients ≥ 50 years with vasculopathic risk factors, presenting with acute isolated third, fourth or sixth cranial nerve palsies. We compared the rate of early neuroimaging referral between neurologists and ophthalmologists at initial presentation, and assessed the proportion of cases in which the final diagnosis has changed after early neuroimaging, in a single medical center. Results: 54 patients were included. After excluding patients with third nerve palsy, the rate of patients referred to early neuroimaging was significantly greater when initially presented to a neurologist compared with an ophthalmologist (29/38 patients were referred to early neuroimaging, of whom twenty by a neurologist and nine by an ophthalmologist, p<0.001). Out of 38 patients presented with fourth or sixth nerve palsies, only 4/38 (10%) were found to have a cause other than presumed microvascular ischemia, and only 2/29 (7%) patients referred to neuroimaging were found to have a causative lesion. Conclusions: The decision to perform early neuroimaging in older patients with acute isolated 4th or 6th nerve palsies and vasculopathic risk factors could be weighed against observation alone. Thorough history taking and prudent physical examination are important for identifying patients with greater risks, therefore needing early neuroimaging.","PeriodicalId":14184,"journal":{"name":"International Journal of Ophthalmology & Visual Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76440960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
