Simulate corneal stromal and epithelial edema with graded haze, contrast reduction, and wavelength-dependent scatter. Tune severity, select edema mode, and inspect ΔE and chromatic shift caused by aqueous imbibition and collagen fibril disorganisation.

Research notes
Corneal edema occurs when endothelial pump failure allows aqueous humor to imbibe into the stroma, disrupting the regular collagen fibril spacing required for transparency. Stromal mode simulates diffuse Gaussian scatter from fibril disorganisation; Epithelial mode adds microcystic texture; Combined/severe mode overlays both with maximum contrast reduction. Severity maps to central corneal thickness (CCT).

Image simulation

Simulations operate in linear sRGB for optical accuracy. Stromal edema mode applies additive Gaussian scatter modelling fibril disorganisation; epithelial mode adds microcystic texture; combined mode overlays both for severe decompensation. ΔE2000 measures perceptual colour shift from scatter-induced whitening. Wavelength-dependent scatter option applies mild blue bias (Rayleigh component, λ⁻⁴) when enabled.
