Background: Patients with Diabetes mellitus (DM) are at risk of developing dry eye disease (DED). We investigated routine laboratory parameters in patients with type 2 DM (T2D) and T2D-DED to identify potential inflammatory markers.
Methods: A retrospective study of 241 randomly selected patients (30 DED non-diabetic, 120 T2D, and 91 with T2D-DED). The neutrophil-to-lymphocyte ratios (NLR), CRP-to-albumin ratios (CAR), and the glycosylated haemoglobin A1c (HbA1c) results were correlated between groups.
Results: The NLR and HbA1c were significantly higher in the T2D-DED group (p≤0.001 and 0.0001, respectively) when compared with T2D and DED non-diabetic groups. CAR was insignificantly high in the three groups (p=0.192). A positive correlation was identified between CAR and NLR in T2D-DED patients (p= 0.008).
Conclusion: In T2D-DED patients, NLR was significantly high and positively correlate with CAR. These results predicate diabetes with dry eye complications, and biomarker-mediated inflammation may have important roles in DED pathogenesis.

Evaluation of dry eye parameters and meibomian gland function using the Lipiscan system in male androgenetic alopecia patients.
Clin Exp Optom
January 2025
Department of Ophthalmology, Giresun University, Giresun, Turkey.
Clinical Relevance: The prevalence of male androgenetic alopecia is increasing worldwide. Evaluation of dry eye parameters and meibomian glands of male androgenetic alopecia patients may help to better understand the effect of this disease on dry eye and to provide appropriate treatment for these patients.
Background: The aim of this work is to evaluate the relationship between male androgenetic alopecia, dry eye, and meibomian gland function.
1-Year real-world outcomes of faricimab in previously treated neovascular age-related macular degeneration.
Eye (Lond)

Maidstone Hospital Eye Department, Hermitage Lane, Maidstone, UK.
Background And Objectives: Faricimab, a bispecific antibody targeting VEGF-A and angiopoietin-2, has shown promise in treating neovascular age-related macular degeneration (nAMD). This study evaluates 1-year outcomes of faricimab in treatment-experienced nAMD patients.
Methods: This single-centre retrospective cohort study included patients previously treated for nAMD who switched to faricimab between November 2022 and March 2024.
Impact of COVID-19 on Ocular Surface Health: Infection Mechanisms, Immune Modulation, and Inflammatory Responses.

Department of Ophthalmology, Henan Provincial People's Hospital, People's Hospital of Zhengzhou University, Zhengzhou 450003, China.
COVID-19, caused by SARS-CoV-2, has presented formidable challenges to global health since its emergence in late 2019. While primarily known for respiratory symptoms, it can also affect the ocular surface. This review summarizes the effects of SARS-CoV-2 on ocular surface immunity and inflammation, focusing on infection mechanisms, immune responses, and clinical manifestations.

: This study aimed to evaluate the therapeutic effects of combined 5% lifitegrast (LF) and tocopherol (TCP) eye drops in a murine experimental dry eye (EDE) model. Female C57BL/6 were divided into seven groups: untreated controls, EDE control, EDE + 0.05% cyclosporin A (CsA), EDE + tocopherol (TCP), EDE + 5% LF, EDE + 5% LF + TCP (once daily), and EDE + 5% LF + TCP (twice daily).

: The aim of the present study was to establish a cut-off value of the Lipid Layer Pattern (LLP) between participants with different subtypes of Dry Eye Disease (DED) including Deficient Dry Eye (ADDE), Evaporative Dry Eye (EDE), and Mixed Dry Eye (MDE). : 240 participants diagnosed with DED according to the Tear Film and Ocular Surface Society in the Dry Eye Workshop II guidelines were included in the study. Tear Meniscus Height (TMH) using the Tearscope illumination and Meibomian Gland Loss Area (MGLA) using the Keratograph 5M were assessed to categorize the participants into an ADDE group, EDE group, or MDE group.
