This study introduces a new vitreous sampling method using fluoresceinated BSS (balanced salt solution) infusion. This technique safely increases vitreous yield, preserving biochemical characteristics for analysis.

Area of Science:

  • Ophthalmology
  • Biochemistry
  • Surgical Innovation

Background:

  • Vitreous sampling is crucial for biochemical analysis in ophthalmology.
  • Current methods may have limitations in yield and patient safety.

Purpose of the Study:

  • To develop an improved vitreous sampling technique.
  • To increase sample yield while minimizing patient risk.

Main Methods:

  • Assessed effects of fluoresceinated BSS on fibroblast activity.
  • Collected paired vitreous samples before and during BSS infusion.
  • Measured protein concentration and contraction-stimulating activity.

Main Results:

  • Fluoresceinated BSS did not negatively impact fibroblast morphology or activity.

  • No statistically significant differences were found in protein concentration or biologic activity between undiluted and diluted samples.

    • Conclusions:

    • Fluoresceinated BSS infusion enables larger vitreous sample collection.
    • This method preserves native biochemical characteristics and enhances patient safety by preventing ocular hypotony.
