Summary: The study aimed to visualize and evaluate the demarcation line after epi-off I-CXL using AS-OCT, finding that it was clearly distinguishable and similar to the one created in standard CXL.

Summary: This study describes a non-contact DAS-OCT system that effectively identifies the presence of peripheral anterior synechia (PAS) in angle closure glaucoma patients by measuring the changes of the anterior chamber angle (ACA). The system shows great potential for guiding the diagnosis of angle closure glaucoma.

Summary: This retrospective study compared the outcomes of accelerated corneal crosslinking (A-CXL) and iontophoresis corneal crosslinking (I-CXL) in the treatment of progressive keratoconus. The results showed that A-CXL was more effective than I-CXL in stabilizing the condition.

Summary: This study proposes a new method for corneal crosslinking using a ruthenium-based water-soluble photoinitiator and visible light. The results demonstrate that the ruthenium-based approach has superior biomechanical properties, biocompatibility, and optical transparency compared to the riboflavin/UV-A method. It offers a promising non-surgical therapy option for all ectatic corneal pathologies.

Summary: This study evaluates the use of AS-OCT in identifying focal changes and informing surgical plans in eyes with Mooren's ulcer. The results show that AS-OCT can accurately identify corneal ulceration, neovascularization, fibrovascular membranes, and focal corneal ectasia. Based on AS-OCT findings, individualized surgical plans can be made. Additionally, AS-OCT can detect small corneal perforations that are undetectable by slit-lamp biomicroscopy.

Summary: This study used AS-OCT to examine 75 eyes of 54 patients with pterygium and analyzed the anatomical features of the pterygium tissue. The results showed that a space was observed beneath the pterygium tissue in most eyes, and the pterygium invaded the Bowman's layer and stromal layer of the cornea.

Summary: A deep learning based corneal segmentation algorithm was used to accurately delineate corneal tissues and successfully characterize changes in epithelial and corneal thickness at different stages of keratoconus (KC) progression based on AS-OCT images. Thickness gradually decreased with KC progression, with more pronounced trends around the pupil center and a slight shift towards the temporal and inferior side. Epithelial thickness gradually decreased from normal eyes to severe KC. In scarring KC, epithelial thickness showed irregular fluctuations.

Summary: The study introduces a novel recombinant human collagen-based scaffold for inducing corneal stroma regeneration, which demonstrates the potential to be an effective transplantation graft for damaged cornea both in vitro and in vivo. The different topological structures used in the study show influence on the growth and differentiation of corneal limbal stromal stem cells, and the results from rat intrastromal keratoplasty support the efficacy of the derived collagen hydrogels in promoting the regeneration of damaged corneal stroma.

Summary: This study introduces a method to evaluate corneal stromal opacity in FECD using optical density measurements by AS-OCT, which was validated in both human and rabbit eye models. Results showed a significant correlation between corneal optical density in FECD patients and other disease characteristics.

Summary: This study investigates the mapping characteristics of corneal epithelial thickness (CET) in a Middle Eastern population and its relationship with age, sex, intraocular pressure, and keratometric power (K). The results show that the central CET is thicker than other zones of the cornea, males have thicker CET than females, and there is a positive correlation between age and CET. The findings of this study are important for refractive surgery decision-making and predicting corneal diseases.

Summary: This study reports the efficacy and safety of repeated CXL for significant progression of keratoconus after a single CXL procedure. The results show that repeated CXL can stabilize the condition and prevent visual deterioration, making it a safe and effective treatment option, especially for young patients.

Summary: The purpose of this study was to investigate the sectorized corneal thickness in eyes with corneal endothelial dysfunction using anterior-segment optical coherence tomography. Data from 53 eyes with corneal endothelial dysfunctions and 18 normal eyes were collected. The results showed that the corneal thickness in the superior sectors of eyes with endothelial dysfunction was thicker than in the inferior sectors, while there were no significant horizontal differences. Based on comparison with normal eyes, the temporal sectors were thicker than the nasal sectors.

Summary: Corneal crosslinking (CXL) surgery halts the progression of keratoconus through a photochemical reaction involving UV light and riboflavin-induced apoptosis of corneal cells. The stiffening effect of CXL primarily occurs in the anterior third of the cornea, and shorter irradiation times may not have the same biological effect.
