Dyes in ocular surgery: principles for use in chromovitrectomy.

Area of Science:

• Ophthalmology
• Surgical Innovation
• Retinal Surgery

Background:

• Vital dyes are increasingly utilized in vitreoretinal surgery.
• Chromovitrectomy enhances visualization and dissection of intraocular membranes.
• Understanding dye properties is crucial for surgical success and patient safety.

Purpose of the Study:

• To review the current state-of-the-art of vital dyes in chromovitrectomy.
• To analyze properties, indications, techniques, and toxicity of vital dyes.
• To discuss current and historical applications of vital dyes in ophthalmic surgery.

Main Methods:

• A critical analysis of existing literature and recent studies.
• Interpretation and commentary on experimental and clinical research.
• Inclusion of authors' clinical and laboratory findings.

Main Results:

• Vital dyes facilitate the removal of intraocular membranes.
• Safety and toxicity of dyes remain areas of debate and further research.
• Bromophenol blue and Brilliant blue are identified as potentially superior novel agents.
• Specific dyes are used for different chromovitrectomy steps: triamcinolone acetonide (vitreous), indocyanine green/infracyanine green/Brilliant blue (ILM), Trypan blue (ERM).

Conclusions:

• Established safety profiles for chromovitrectomy dyes are lacking.
• Minimizing dye concentration and volume is advised for current procedures.
• Further investigation into novel, specific vital dyes is warranted.
