Area of Science:

  • Ophthalmology
  • Neuroscience
  • Surgical Techniques

Background:

  • The optic nerve is crucial for vision.
  • Accurate surgical access to the optic nerve is challenging.
  • Minimally invasive techniques are needed to prevent ocular damage.

Purpose of the Study:

  • To describe a novel optic nerve sectioning technique in rats.
  • To enable direct intraoperative visualization of the optic nerve.
  • To develop cost-effective surgical retractors.

Main Methods:

  • A specific surgical approach for optic nerve sectioning in rats.
  • Techniques to ensure no damage to the anterior segment of the eye.
  • Design and construction of custom surgical retractors.

Main Results:

  • The described technique allows direct visualization of the optic nerve.
  • The surgical method prevents damage to the front of the eye.
  • Inexpensive and functional retractors were successfully constructed.

Conclusions:

  • This technique offers a safe and effective method for optic nerve surgery in rats.
  • The procedure minimizes risk of ocular trauma.
  • The developed retractors provide a practical solution for surgical access.
