Research notes
Fuchs endothelial dystrophy results from progressive endothelial cell loss and
guttae (extracellular matrix excrescences) on Descemet membrane, causing endothelial pump failure
and corneal oedema. Corneal haze mode applies diffuse Gaussian scatter; Morning edema mode models
diurnal worsening; Advanced scatter simulates guttae-mediated micro-aberrations. Severity maps to
endothelial cell density (ECD) and corneal central thickness (CCT).

Clinical notes: Fuchs dystrophy scatter is predominantly achromatic
(broadband white) in early-moderate stages. Guttae micro-aberrations in advanced stages
may introduce slight wavelength-dependent scatter bias. Scatter weights adjust R/G/B channel
weighting. Not a clinical diagnostic — see model assumptions for limitations.
Model assumptions & limits
- Corneal haze modelled as additive Gaussian white scatter in linear sRGB.
- Severity curves are clinical heuristics mapped to ECD/CCT grades.
- ΔE and chromaticity metrics depend on display colour profile.
