Abstract
Abstract
Purpose
To assess the tear film layers and Meibomian glands by a noninvasive ocular surface analyzer in patients with and without type 1 diabetes mellitus (T1DM).
Methods
Eighty-eight participants were enrolled in this study: 44 patients with T1DM without diabetic retinopathy, and 44 patients as a control group, between 18 and 49 years old. Limbal and bulbar redness classification, lipid layer thickness (LLT), tear meniscus height (TMH), first and mean noninvasive tear break-up time (FNIBUT and MNIBUT, respectively), and Meibomian glands loss (MGL) were assessment through the ICP Ocular Surface Analyzer (OSA). Schirmer’s I test (SIT), the fluorescein tear break-up time test (TFBUT), OSDI and SPEED questionnaires, and percentage of glycosylated hemoglobin (HbA1c) were also tested.
Results
The T1DM group showed higher limbal and bulbar redness (p = 0.010) and lower LLT (p < 0.001), TMH (p < 0.001), FNIBUT (p < 0.001), MNIBUT (p < 0.001), SIT (p = 0.001), and TFBUT (p < 0.001) than the control group. A higher percentage of MGL was found in the T1DM group in the upper (p = 0.097) and lower (p < 0.001) eyelids. No significant differences were found in dry eye symptoms across the OSDI and SPEED questionnaires between the two groups.
Conclusion
Patients with T1DM without signs of retinopathy showed involvement of the mucoaqueous and lipid layers of the tear film, as well as a higher percentage of MGL, using a noninvasive analyzer. Dry eye disease in people with T1DM cannot be ruled out by anamnesis and subjective symptom questionnaires alone; therefore, these patients should undergo regular anterior pole examinations.

Abstract
Trace elements exposure is proposed to play a role in the pathogenesis of the systemic disease. Emerging studies have suggested that trace metal exposure may contribute to dry eye disease. Our study primarily aimed to investigate the association between trace metal exposure in tear samples and the presence of dry eye metrics in the shipyard industry. Overall, 84 eligible participants from the shipyard industry were included in this cross-sectional study. The parameters for identifying dry eye symptoms included O.S.D.I., SPEED, N.I.B.U.T., and ocular surface conditions, such as tear meniscus height, eye blinking, and meibomian gland area were performed by S.B.M. sistemi ocular surface analyzer. The concentration of tear trace elements was detected by inductively coupled plasma mass spectroscopy (ICP-MS). The association between tear trace elements and dry eye parameters was investigated using regression models. Participants in the exposure group had significantly higher levels of tear Pb than the control group. In the exposure group, tear Pb was significantly associated with increased SPEED and O.S.D.I. score with beta coefficients of 0.144 (95% CI 0.092, 0.197), 0.121 (95% CI 0.049, 0.194), respectively, and decreased lower and upper meibomian gland area with beta coefficients of - 0.158 (- 0.283, - 0.033) and - 0.228 (- 0.396, - 0.061), respectively. Tear trace elements exposure is considered to impact the appearance of dry eye metrics. Improving the occupational environment and monitoring the ocular surface health may benefit workers under exposure to trace elements.

Abstract
Purpose To investigate the risk and protective factors of dry eye disease (DED) in patients with type II diabetes mellitus (DM). Design A retrospective cohort study using Chang- Gung research database collecting data from 2005 to 2020. Methods Patients with type II DM were included, and those with previous ocular diseases were excluded. Ten thousand twenty nine developed DED (DED group), and 142,491 didn't (non-DED group). The possible risk and protective factors were compared and analyzed using the logistic regression model. Results A majority of the DED group were female with significantly higher initial and average glycated hemoglobin levels, and higher incidence of diabetic neuropathy and retinopathy. In conditional logistic regression model, advanced age was a risk factor. After adjusting for sex, age, and DM duration; average glycated hemoglobin level, diabetic neuropathy, retinopathy, and nephropathy with eGFR 30 ~ 59 and intravitreal injection, vitrectomy, pan-retinal photocoagulation, and cataract surgery were contributing factors of DED. Considering antihyperglycemic agents, DPP4 inhibitor, SGLT2 inhibitor, GLP-1 agonist, and insulin monotherapy and dual medications combining any two of the aforementioned agents were protective factors against DED compared with metformin alone. In the monotherapy group, SLGT2 inhibitor had the lowest odds ratio, followed by GLP1 agonist, DPP4 inhibitor, and insulin. Conclusions DED in patients with DM is associated with female sex, advanced age, poor diabetic control, microvascular complications and receiving ocular procedures. GLP-1 agonist, SGLT-2 inhibitor, DPP4 inhibitor, and insulin are superior to metformin alone in preventing DM-related DED. A prospective randomized control trial is warranted to clarify our results.

Abstract
SIGNIFICANCE The clinical features of meibomian gland disease include altered tear film stability, damage to the ocular surface, symptoms of ocular surface irritation, and visual fluctuations. Finding an adequate treatment to alleviate a patient's signs and symptoms is vital to caring for those with dry eye disease resulting from meibomian gland disease. PURPOSE The purpose of this analysis was to determine whether the controlled heating of meibomian glands with the SmartLid devices (TearCare) combined with evacuation of the liquefied meibum using a handheld clearance assistant would improve a patient's dry eye symptoms (as measured by the Standardized Patient Evaluation of Eye Dryness [SPEED] questionnaire) and signs (as measured by meibomian gland expression [MGE] scores). METHODS This study involved a retrospective analysis of data gathered in a single-center ophthalmology/optometry practice. The symptom frequency and severity were assessed using the SPEED questionnaire, and the signs were assessed via MGE scores before and after (8 to 12 weeks) treatment. A further analysis evaluating efficacy in subgroups based on age, race, and sex was performed. A statistical analysis was performed with t tests for group comparisons. RESULTS A SPEED questionnaire was answered by 92 patients with dry eye disease. In addition, each patient's meibomian gland function was recorded as MGE scores for each eye (176 eyes). These procedures were completed before and approximately 8 weeks after a single bilateral TearCare treatment. The median total SPEED score was reduced from 16 to 9, and the total MGE scores improved from 5.0 to 9.0 in the right eye and 4.0 to 9.0 in the left eye after a single TearCare treatment. CONCLUSIONS A single TearCare treatment was effective in reducing both the signs and symptoms of dry eye in all subjects.

Abstract
AIMS The objectives of this study were to explore physiological and pathological changes in the corneas of diabetic rats by intervening in the expression of silent information regulator 1 (Sirt1) and to investigate whether Sirt1 can regulate the activation of endoplasmic reticulum stress (ERS) while influencing corneal epithelial cell apoptosis under high glucose conditions. MATERIALS AND METHODS Using 8-week old Sprague-Dawley rats, we established a model of type 1 diabetes, with or without Sirt1 intervention. Clinical evaluation was performed once per week. Primary rat corneal epithelial cells (RCECs) were cultured by combining Sirt1 intervention under high glucose conditions. Generation of reactive oxygen species (ROS), apoptosis, and the expression of Sirt1 and ERS-related proteins were evaluated in rat corneal tissues and RCECs. KEY FINDINGS During the intervention, clinical evaluation of the ocular surface, ROS generation, apoptosis, and protein expression of ERS-related proteins in corneal tissue and cultured RCECs were altered with Sirt1expression levels. SIGNIFICANCE Sirt1 expression influences the pathological progression of diabetic keratopathy, plays an important role in regulating the ERS pathway, and decreases corneal epithelial cell apoptosis.

Abstract
Background:
Studies have shown a higher incidence of dry eye among patients with diabetes compared to patients without diabetes. However, information regarding dry eye in patients with proliferative diabetic retinopathy and laser therapy indication is not sufficient.
Objective:
To estimate the clinical manifestation of dry eye syndrome in patients with proliferative diabetic retinopathy and laser therapy indication.
Method:
A cross-sectional study was performed during a local evaluation campaign of diabetic patients with vision disabilities at the Instituto Cearense de Oftalmologia in Fortaleza, CE, Brazil. Patients with proliferative diabetic retinopathy and laser therapy indication were included in the study. An anamnesis directly to dry eye complaints was performed, and eligible participants completed the Ocular Surface Disease Index (OSDI) questionnaire. The slit lamp examination was performed with fluorescein staining; the tear break-up time (TBUT) was measured, and conjunctiva and corneal was evaluated using Rose Bengal (RB) staining. Finally, the Schirmer I test was performed.
Results:
Twenty-five patients were included in the study with a diagnostic time of Diabetes Mellitus ranged from 1 to 35 years, with an average of 17.2 ± 8.7 years. In our sample, 14 patients (56%) reported glycemic control with insulin, while 11 patients (44%) had oral hypoglycemic agents. The most prevalent complaint was blurred vision (96% of patients) followed by low visual acuity (92%). A less prevalent complaint was pain (44%). The mean OSDI score was 49.4 ± 24.2. TBUT was less than 10 seconds in 21 patients (84%), and RB staining grade was more than 3 in 13 patients (52%). The results of the Schirmer I test ranged from 2 to 35 mm, with a mean of 13.57 ± 9.78 mm. It was smaller than 10 mm in 15 patients (60%).
Conclusion:
The frequency of manifestation of dry eye syndrome was very common in patients with proliferative diabetic retinopathy and laser therapy indication. Ocular surface care should be provided for those patients with significant ocular morbidity.

Abstract
Diabetes mellitus is an epidemic in the US and abroad. With the advent of new contact lens technology, the use of contact lenses as glucose sensors in lieu of the traditional finger stick is quickly becoming realized. This has the potential to rapidly expand the contact lens market into this growing patient population. The independent cellular and physiological effects of contact lens wear and diabetes on the corneal epithelium have been described. However, little evidence exists to date to support whether there is increased risk associated with contact lens wear in diabetes. The focus of this review is to discuss what is known about the cellular effects of contact lenses on the corneal epithelium, the pathophysiological changes in the corneal epithelium that occur in diabetes, and whether an increased risk for corneal epithelial damage and/or infection may negatively impact safety in diabetic contact lens wearers. Available data indicates that there are inherent risks associated with contact lens wear in diabetics. Importantly, eye care practitioners fitting contact lenses in the diabetic patient need to carefully consider the duration of disease, the level of glycemic control, the presence of retinopathy, and the patient's overall health.
