Which landmark is used to find the edge of the optic disc?

Explanation:
The edge of the optic disc is defined by where Bruch’s membrane ends around the nerve head. This termination creates the Bruch’s membrane opening, which marks the disc margin on imaging and exam visuals. The lamina cribrosa lies deeper within the optic nerve behind this border, not at the visible margin. The macula fovea is a separate retinal region for sharp central vision, and retinal veins pass through the disc but don’t define its edge. So Bruch’s membrane is the key landmark used to locate the edge of the optic disc.
