Purpose: To compare the corneal epithelial wound healing effects of RCI001, Solcoseryl, and polydeoxyribonucleotide (PDRN) in a rat alkali burn model.
Methods: In 40 male Sprague-Dawley rats, we induced alkali burn using filter paper soaked in 0.2N sodium hydroxide. The rats were then treated with topical 0.5% RCI001, 1.0% RCI001, Solcoseryl, or PDRN twice a day for 2 weeks. Corneal epithelial integrity and epithelial healing rate were measured at day 0, 3, 5, 7, 10, and 14. Histologic and immunohistochemistry findings were also assessed.
Results: Both the 0.5% and 1.0% RCI001 groups showed significantly more epithelial healing compared to the control group at day 5, 7, 10, and 14 (each p < 0.05). No statistical difference was found between the 0.5% and 1.0% RCI001 groups. Neither the Solcoseryl nor the PDRN groups showed a significant difference from the control. RCI001 treatment resulted in significantly reduced stromal edema, and a trend towards less inflammatory cell infiltration.
Conclusions: Topical application of RCI001 showed enhanced corneal epithelial wound healing in the murine corneal alkali burn model, presumably by suppressing inflammation. Meanwhile, Solcoseryl and PDRN did not show sufficient therapeutic effects compared to RCI001.

Background: Conjunctival sporotrichosis is a rare fungal infection, typically presenting as granulomatous lesions. Its manifestations can be atypical, particularly in immunosuppressed patients. Here, we present a rare case of a Mooren's ulcer patient with bulbar conjunctival Sporotrichosis presenting as a salmon-pink tumor.

Extracellular vesicles (EVs), defined as membrane-bound vesicles released from all cells, are being explored for their diagnostic and therapeutic role in dry eye disease (DED). We systematically shortlisted 32 articles on the role of EVs in diagnosing and treating DED. The systematic review covers the progress in the last 2 decades about the classification and isolation of EVs and their role in DED.

Aim: This study aimed to evaluate the impact of pterygium excision combined with autologous limbal stem cell transplantation on microvascular density, tear film stability, and corneal wound healing in the management of pterygium.
Methods: A retrospective analysis was conducted on 317 patients with pterygium who underwent treatment between January 2021 and January 2024. Patients were divided into a control group (pterygium excision alone, n = 161) and a study group (pterygium excision combined with autologous limbal stem cell transplantation, n = 156) based on the surgical approach.
Novel full-thickness biomimetic corneal model for studying pathogenesis and treatment of diabetic keratopathy.

Diabetic keratopathy (DK), a significant complication of diabetes, often leads to corneal damage and vision impairment. Effective models are essential for studying DK pathogenesis and evaluating potential therapeutic interventions. This study developed a novel biomimetic full-thickness corneal model for the first time, incorporating corneal epithelial cells, stromal cells, endothelial cells, and nerves to simulate DK conditions .

Purpose: To explore the destructive and protective effects and therapeutic targets of IL-36 cytokines in dry eye disease using a murine dry eye model.
Methods: A dry eye model was established in C57BL/6 mice exposed to desiccating stress (DS) with untreated mice as controls. A topical challenge model was performed in normal mice with exogenous rmIL-36α, rhIL-38 and 2% ectoine, or PBS vehicle.
