Summary
This study models corneal transport, simulating thickness changes from osmotic pressure. The differential model aids understanding of in vivo corneal behavior and its response to perturbations.
Area of Science:
- Ophthalmology
- Biophysics
- Biomedical Engineering
Background:
- The cornea's thickness is regulated by fluid transport across its membranes.
- Understanding in vivo corneal behavior requires accurate physiological models.
Purpose of the Study:
- To develop a differential model of the corneal transport system.
- To simulate corneal thickness changes in response to osmotic perturbations.
Main Methods:
- Coupled viscous flow modeling within the corneal stroma.
- Application of irreversible thermodynamics for membrane transport.
- Numerical simulation validated against experimental data.
Main Results:
- The model successfully reproduced corneal thickness changes due to endothelial perturbations.
- Sensitivity analysis identified key transport coefficients influencing corneal behavior.
Conclusions:
- The developed model provides a valuable tool for studying corneal physiology in vivo.
- Further research can refine transport coefficients for enhanced predictive accuracy.
