This study details a rodent eye micro-dissection technique preserving the third eyelid for precise ocular tissue isolation. This method aids in studying eye physiology and cell therapy interventions by maintaining spatial orientation.

Area of Science:

  • Ophthalmology
  • Anatomical Pathology
  • Surgical Techniques

Background:

  • Accurate dissection of ocular tissues is crucial for understanding eye physiology and disease.
  • Existing methods may not preserve critical anatomical landmarks for spatial analysis.
  • The rodent third eyelid offers potential advantages for maintaining ocular orientation.

Purpose of the Study:

  • To present a refined micro-dissection technique for rodent eyes that includes the third eyelid.
  • To enable the isolation of specific ocular tissues (cornea, neural retina, RPE, lens) for various analyses.
  • To leverage the third eyelid for maintaining nasal-temporal orientation in dissected ocular samples.

Main Methods:

  • Enucleation of the rodent eyeball with the attached third eyelid.

  • Incision at the corneal limbus followed by circumferential cuts along the corneal-scleral junction to create anterior and posterior eyecups.
  • Dissection of neural retina and retinal pigment epithelial (RPE) layers using forceps.
  • Radial cuts from the periphery to the optic center to flatten the eyecups for mounting.

    • Main Results:

    • Successful isolation of corneal tissue, neural retina, RPE, and lens.
    • Preservation of the third eyelid facilitates clear nasal-temporal orientation of the eyecups.
    • The floret-shaped eyecups are suitable for wholemounts, cryo-sectioning, and single-cell suspensions.
    • The technique has been validated for corneal wholemounts and retinal sections.

    Conclusions:

    • This micro-dissection method provides a reliable way to obtain oriented ocular tissues from rodent eyes.
    • The inclusion of the third eyelid is advantageous for studies requiring spatial topographical information.
    • The technique supports research in cell therapy interventions and targeted physiological validation in ophthalmology.
