Kayser-Fleischer ring and associated cataract in Wilson's disease
American Journal of Ophthalmology
|March 1, 1975
Summary
This study examines copper deposition in Wilson's disease (hepatolenticular degeneration), revealing cellular activity is key for copper accumulation in the cornea and lens basement membranes, not simple diffusion.
Area of Science:
- Ophthalmology
- Genetics
- Biochemistry
Background:
- Wilson's disease (hepatolenticular degeneration) is a genetic disorder of copper metabolism.
- Clinical manifestations include Kayser-Fleischer rings and cataracts.
Observation:
- Histopathologic, histochemical, and electron microscopy of a patient's cornea revealed copper deposition in Descemet's membrane and Hassall-Henel warts.
- Copper was also observed in the anterior and posterior lens capsule.
Findings:
- Copper accumulation occurred in the cornea and lens basement membranes.
- No degenerative changes were noted in the lens epithelial or cortical cells.
Implications:
- Cellular activity, rather than simple diffusion, is proposed as the mechanism for copper deposition in these basement membranes.
- Understanding this mechanism could inform future therapeutic strategies for Wilson's disease.
