Some examples of entoptical effects include: Floaters depiction Purkinje tree depiction. Floaters or muscae volitantes are slowly drifting blobs of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background (such as the sky) or a point source of diffuse light very close to the eye.
Oculocardiac reflex can be profound during eye examination for retinopathy of prematurity. [5] However, this reflex may also occur with adults. Bradycardia, junctional rhythm and asystole, all of which may be life-threatening, [6] can be induced through this reflex. This reflex has been seen to occur during many pan facial trauma surgeries due ...
The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [1]

[2] The Stiles–Crawford effect of the second kind is the phenomenon where the observed color of monochromatic light entering the eye near the edge of the pupil is different compared to that for the same wavelength light entering near the center of the pupil, regardless of the overall intensities of the two lights.
