Limportanza di un colorante coesivo
in cromovitrectomia
Prof. Cesare Mariotti
Universit Politecnica delle Marche
Clinica Oculistica
The term chromovitrectomy refers to the use of vital dyes during
vitreoretinal surgery to assist in the identification of pre-retinal
tissues and membranes.
Introduction
Trieste, 16-17-18 giugno 2016
Staining agents may be classified according to their
capacity to stain different structures:
- Epiretinal membranes
- Inner Limiting membranes
- Vitreous: The crystals of the steroid adhere to the acellular
tissue, thereby enabling a clear contrast between the
empty vitreous cavity compared to areas with the vitreous fibers
Introduction
Trieste, 16-17-18 giugno 2016
Staining agents may also be classified according to their physical and chemical
properties:
Cohesion is a key property for vital dye
Cohesion: Physics. the molecular force between particles
within a body or substance that acts to unite them.

 Cohesive properties of trypan blue 0.18% and blulife 0,03% help the surgeon to:
o Reach the area to be stained without dispersion
o Direct the dye precisely on the area of coloration
o Remove the dye without excessive dispersion

Editor's Notes

  • #3: Cromo vitrectomia si riferisce all'uso di coloranti per colorare le membrane epiretiniche e il vitreo durante la chirurgia vitreoretinica in modo da facilitare la loro visualizzazione intraoperatoria
  • #4: Cromo vitrectomia si riferisce all'uso di coloranti per colorare le membrane epiretiniche e il vitreo durante la chirurgia vitreoretinica in modo da facilitare la loro visualizzazione intraoperatoria
  • #6: Nella formulazione del colorante, definita empiricamente, si e ottenuta una stabilit di forze intermolecolari che nelle condizioni di utilizzo riduce la formazione delle turbolenze in contatto con acqua, il fenomeno chiamato nella dinamica dei fluidi 束Rayleigh-Taylor instability損.
