Clinical Relevance: Effective treatment of corneal epithelial defects is crucial to prevent secondary infectious keratitis and visual impairment due to loss of corneal transparency. Therefore, it is important to determine the effect of different topical agents on corneal wound healing response.
Background: The aim was to compare the effects of three different eye drops on corneal epithelial wound healing in an experimental model.
Methods: Twenty-four eyes of 24 female BALB/c mice were included. A 2 mm central corneal epithelial defect was created. Topical Coenzyme Q10 + Vitamin E D-α-TPGS 4 × 1 was applied to Group A ( = 6), topical Sodium hyaluronate + Xanthan Gum + 0.3% Nethylmicine 4 × 1 to Group B ( = 6) and topical Sodium hyaluronate 4 × 1 to Group C ( = 6). Group D ( = 6) was the control group without treatment. Clinical scoring according to corneal fluorescein staining and histopathological evaluations was performed.
Results: Clinical scores according to corneal fluorescein staining were similar in all groups on days 1 ( = 0.05), 2 ( = 0.15) and 3 ( = 0.62). Electron microscopy revealed disruption of intercellular junctions between corneal epithelial cells and intracellular vacuole formation in all groups except Group A. Corneal epithelial thickness and superficial epithelial microvillus arrangement were close to normal in Group A.
Conclusion: Although there was no difference in clinical scores between groups, electron microscopy revealed a better organised epithelium with normal configuration of microvilli and less vacuolisation in Group A.

Purpose: To retrospectively describe the performance of topical insulin in persistent corneal epithelial defects (CED) and persistent corneal ulcers.
Methods: We reviewed cases of patients treated for persistent CED and persistent corneal ulcers using topical insulin in a concentration of 25 IU per milliliter three times per day. The closure rate of CED and corneal ulcers was the main outcome measure.

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.

To report the cosmetic, clinical, and visual outcomes of a combined surgical approach for treating a corneal/limbal dermoid using excision and a three-layered amniotic membrane graft with fibrin glue. An 18-year-old female presented with impaired vision and ocular discomfort caused by a prominent dome-shaped limbal congenital dermoid on the inferotemporal cornea, resulting in a significant aesthetic concern. A full assessment, including refraction, best-corrected visual acuity (BCVA), corneal topography, aberrometry and anterior segment OCT (AS-OCT) was conducted to plan the surgical approach.

In this study, we aim to evaluate in vivo confocal microscopy (IVCM) findings of corneal stromal dystrophies (CSDs) including granular, macular and lattice corneal dystrophy that can be used for differential diagnosis and monitoring recurrences after surgical interventions. : Patients diagnosed with CSD who were followed-up in the cornea and ocular surface unit were included in this study. IVCM was performed using the Heidelberg Retina Tomograph 3, Rostock Cornea Module (Heidelberg Engineering, Germany) and anterior segment optical coherence tomography (AS-OCT) imaging was performed using the Spectralis OCT (Heidelberg Engineering, Germany).

Corneal ulcer is one of the most important ophthalmic emergencies. A portable, recordable, and smartphone-attachable slit-lamp device called the "Smart Eye Camera" (SEC) is introduced to compare evaluating corneal ulcers between the SEC and the conventional slit-lamp. A total of 110 participants were included in the study, consisting of 55 patients with corneal ulcers and 55 age- and gender-matched healthy volunteers as controls.
