What is this point called?

Yes, it is connected.
A blind spot, scotoma, is an obscuration of the visual field. A particular blind spot known as the blindspot, or physiological blind spot, or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through it. Since there are no cells to detect light on the optic disc, a part of the field of vision is not perceived. The brain interpolates the blind spot based on surrounding detail and information from the other eye, so the blind spot is not normally perceived.

the optic nerve is a bundle of nerve fibers starting at the photo receptors of the retina and meet at the optic chiasm
although they continue on after that they are, from that point on, called the optic tract
the reason for this is because they are, at that point, within the CNS
it would be good to see your way to some research

Yes, it's a continuation of cells to the retina. It connects the brain in the eye. The optic nerve carries signals of light, dark, and color.
