How is the injury induced in this model?
The injury is induced by elevating intraocular pressure in mice.
What are the main advantages of this technique?
It targets ocular structures specifically while minimizing damage to surrounding tissues.
What are the key outcomes measured?
Outcomes include inflammation, oxidative stress, and dysfunction in the retinal neurovascular unit.
Is there a visual guide available for the procedure?
Yes, a video demonstration is provided to assist with the surgical techniques.
