Corneal collagen cross-linking (CXL) is the only conservative treatment currently available to halt keratoconus progression by improving the biomechanical rigidity of the corneal stroma. The aim of this manuscript is to highlight the methods of three different protocols of CXL: conventional CXL (C-CXL), accelerated CXL (A-CXL), and iontophoresis CXL (I-CXL).

Porcine Ex vivo Cornea Model of Bacterial Keratitis: A Technique to Establish Bacterial Infection in Corneal Epithelial Cells
0 Views •
2025
This video describes a protocol to set up an ex vivo model for bacterial keratitis using a corneoscleral button dissected from the porcine eye. Inoculated bacteria traverse the corneal epithelial incisions to invade the underlying stroma and establish an infection within the corneal tissues that mimic the in vivo infection.

The aqueous humor is a high-yield liquid biopsy for retinoblastoma, intraocular cancer that cannot be biopsied in vivo due to the risk of extraocular spread. Herein, a method for safely extracting aqueous humor via clear corneal paracentesis and steps for genomic analysis to identify prognostic biomarkers are presented.

FAQs
Collagen organization provides a structural basis for assessing corneal transparency and integrity. Disruption of this arrangement can indicate tissue injury associated with inflammation or pathogen-related damage, while preserved organization may support a more intact stromal state. Examining these patterns alongside keratocyte and extracellular-matrix findings helps relate microscopic structural changes to potential effects on vision.
Keratocytes and the extracellular matrix represent complementary aspects of stromal condition. Keratocyte changes can provide cellular evidence of tissue responses, whereas extracellular-matrix assessment shows how the connective-tissue environment is organized or altered. Evaluating both helps distinguish cellular responses from broader architectural disruption and supports interpretation of how disease or inflammation affects corneal integrity.
Edema, inflammatory-cell infiltration, collagen disruption, and pathogen-associated damage are important findings when evaluating infection-related injury. These observations provide different kinds of evidence: edema reflects altered tissue condition, infiltration indicates an immune response, and collagen disruption signals structural damage. Considering the findings together can connect microbial invasion with host defense and loss of stromal integrity.
A basic assessment can combine microscopy, histological evaluation, and quantitative imaging. Microscopy supports examination of stromal architecture and cellular changes, histological assessment helps evaluate tissue organization and inflammatory features, and quantitative imaging supplies measurable structural information. Selecting or combining these approaches allows researchers to compare stromal changes systematically across disease states or treatment conditions.
Corneal stroma analysis is useful when a study needs to determine whether treatment-related changes affect tissue structure or cellular responses. Researchers can compare measurements of edema, inflammatory-cell infiltration, collagen organization, or pathogen-associated damage across conditions. These outcomes help characterize whether a therapy is associated with altered inflammation, reduced structural injury, or changes relevant to corneal integrity and vision.
In immunology and infection studies, stromal measurements help link microbial invasion to host defense, tissue injury, and healing. Structural and cellular observations can reveal how immune activity changes the cornea during disease and recovery. This context supports disease characterization, investigation of inflammation-driven damage, and evaluation of how tissue responses may influence visual function.
