Purpose of the Study:

  • To refine the trypsin digestion technique for obtaining high-quality iris vascular casts.
  • To improve the visualization of the iris microvasculature.

Main Methods:

  • Modified the Kuwabara and Cogan trypsin digestion method.
  • Incorporated pigment epithelium scraping.
  • Utilized repeated bleaching and prolonged enzymatic digestion.

Main Results:

  • Successfully obtained vascular casts of the iris.
  • The modified technique enhanced the clarity and detail of the vascular structures.
  • Demonstrated improved visualization of the iris microvasculature.

Conclusions:

  • The modified trypsin digestion technique is effective for preparing iris vascular casts.
  • This method offers a valuable tool for studying iris vascular morphology and pathology.
  • Enhanced visualization aids in understanding ocular vascular diseases.
