|October 1, 1986
Summary
Histopathology reveals keratoconus posticus circumscriptus may stem from a corneal development anomaly. Electron microscopy supports this, noting abnormal intercellular junctions and collagen fiber diameters, suggesting a fibrillogenesis disturbance.
Area of Science:
- Ophthalmology
- Corneal Pathology
- Electron Microscopy
Background:
- Keratoconus posticus circumscriptus is a rare corneal condition.
- Understanding its etiology is crucial for effective management.
Observation:
- Histopathological examination of the cornea was performed.
- Electron microscopy was utilized to investigate cellular structures.
Findings:
- Findings suggest a potential corneal development anomaly.
- Abnormal intercellular junctions (gap junctions) were observed between basal epithelial cells.
- Variations in collagen fiber diameters (10-30 nm) indicate a disturbance in fibrillogenesis.
- Stromal cell degeneration appears to be the cause of the fibrillogenesis disturbance.
Implications:
- This study provides insights into the pathogenesis of keratoconus posticus circumscriptus.
- Further research may elucidate specific developmental pathways involved.
- Understanding the underlying anomaly could lead to novel therapeutic strategies.
