Pseudovitreous fluid based on sodium carboxymethylcellulose

Area of Science:

• Ophthalmology
• Biomaterials Science
• Polymer Chemistry

Background:

• Vitreous replacement is crucial after vitreoretinal surgery.
• Current vitreous substitutes have limitations.
• Need for biocompatible and safe vitreous substitutes.

Purpose of the Study:

• To evaluate a sodium carboxymethylcellulose-based solution as a pseudovitreal fluid.
• To assess the biocompatibility and tolerance of this synthetic polymer in vivo.

Main Methods:

• A viscous physiologic solution of sodium carboxymethylcellulose was prepared.
• The solution was injected into the vitreous cavity of rabbit eyes following vitrectomy.
• Ocular tissues were observed over a six-month period.

Main Results:

• The sodium carboxymethylcellulose solution was successfully injected and maintained its viscosity.
• No significant adverse reactions or inflammation were observed in the treated eyes.
• The material was well-tolerated throughout the six-month observation period.

Conclusions:

• Sodium carboxymethylcellulose represents a promising candidate for vitreous replacement.
• This synthetic polymer demonstrates good biocompatibility and safety for ocular use.
• Further research is warranted to explore its clinical application in vitreoretinal surgery.
