Definitions:

Optic Disc

The point of exit for ganglion cell axons leaving the eye. Because there are no rods or cones overlying the optic disc, it creates a blind spot in visual fields.

Sensory Retina

The part of the retina that contains photoreceptor cells (rods and cones) responsible for converting light into electrical signals for vision.

Macula Lutea

A region in the retina responsible for high-acuity vision where a high concentration of photoreceptor cells are located.

Fovea Centralis

A small pit in the retina of the eye where visual acuity (sharpness) is highest, due to a high concentration of cone cells.
