Summary
Schnyder Crystalline Dystrophy, a rare corneal condition, was studied in three patients. Histopathology revealed characteristic stromal changes and elevated serum lipids in some cases, aiding diagnosis.
Area of Science:
- Ophthalmology
- Histopathology
- Biochemistry
Background:
- Schnyder Crystalline Dystrophy (SCD) is an inherited eye disease affecting the cornea.
- Understanding its pathological features and biochemical markers is crucial for diagnosis and management.
Observation:
- Three cases of SCD were analyzed, including incipient and advanced stages.
- Lamellar keratoplasty was performed on one advanced case, with corneal buttons examined histopathologically.
- Microscopic analysis revealed characteristic stromal changes, including lucent vacuoles and rod-like structures.
Findings:
- Oil red O staining confirmed lipid deposition within the corneal stroma.
- Electron microscopy identified small lucent vacuoles and rod-like structures in stromal cells.
- Two of the three patients exhibited elevated serum total cholesterol and phosphatide levels.
Implications:
- These findings reinforce the histopathological and biochemical hallmarks of Schnyder Crystalline Dystrophy.
- Early diagnosis may be supported by identifying stromal lipid deposits and serum lipid abnormalities.
- Further research into SCD pathogenesis and potential therapeutic targets is warranted.
