Purpose: To evaluate changes in ocular surface indices and tear cytokines after cataract surgery in type 2 diabetic patients.
Methods: Ocular surface indices and concentrations of tear cytokines (MCP-1, IL-6, IL-8, and VEGF) were evaluated at baseline and one week and one month postoperatively.
Results: Patients (30 diabetic and 30 control) were enrolled. In the diabetic group, changes in ocular symptom and tear breakup time remained until one month postoperatively ( < .05, respectively); in the control group, ocular symptom increased at one week postoperatively ( = .015). MCP-1 level in the diabetic group significantly increased postoperatively (all < .05); however, in the control group, the IL-8 level was significantly decreased postoperatively (all < .05). MCP-1 concentration was negatively correlated with TBUT in the diabetic group.
Conclusion: Diabetic patients can experience more prominent changes after surgery and these changes were accompanied by an increase of several tear cytokines.

Department of Ophthalmology, University of California San Francisco, San Francisco, California. Electronic address:
Purpose To determine the corneal topographic characteristics of children with blepharokeratoconjunctivitis (BKC), a chronic inflammatory ocular surface disease involving the lid margin, conjunctiva, and cornea. Methods The corneal topography of 21 children diagnosed with BKC between March 2008 and June 2019 at a single institution were reviewed retrospectively. Pachymetry and asymmetry indices were also analyzed.

Electronic address:
Purpose: To introduce and validate quantitative oblique back-illumination microscopy (qOBM) as a label-free, high-contrast imaging technique for visualizing conjunctival goblet cells (GCs) and assessing their functional changes.
Methods: qOBM was developed in conjunction with moxifloxacin-based fluorescence microscopy (MBFM), which was used for validating GC imaging. Initial validation was conducted with polystyrene beads, followed by testing on normal mouse conjunctiva under both ex-vivo and in-vivo conditions.
Impact of COVID-19 on Ocular Surface Health: Infection Mechanisms, Immune Modulation, and Inflammatory Responses.

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.
