    Area of Science:

    • Ophthalmology
    • Cell Biology
    • Medical Imaging

    Context:

    • Specular microscopy (SM) is crucial for analyzing corneal endothelium.
    • Standardized techniques are needed for morphological and morphometric analysis.
    • Current methods require efficient data analysis and storage solutions.

    Purpose:

    • To establish a standardized examination technique for specular microscopy (SM).
    • To implement efficient methods for immediate analysis, documentation, and storage of corneal endothelial data.
    • To validate a rapid screening technique for estimating mean cell density (mcd).

    Summary:

    • A standardized technique for specular microscopy (SM) is presented, including morphological classification and quantitative morphometric analysis.
    • Mean cell density (mcd) can be rapidly estimated by comparing viewfinder images with standardized micrographs.
