Intraocular Pressure Elevation Technique

Intraocular pressure (IOP) elevation was achieved via a vitreous chamber cannula placed in one randomly chosen eye. As previous^{29 (link)}, the cannula consisted of a 27 G needle (Fig. S1) connected to a saline reservoir (60 mL, Baxter International Inc. Toongabbie, NSW, Australia) via polyethylene tubing (0.8 mm outer, 0.4 mm inner diameter, Unomedical, Sydney, NSW, Australia). IOP was controlled by placing the reservoir to heights pre-calibrated against a manometer (Livingstone, Sydney, NSW, Australia).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
