- If necessary, ophthalmological examination – examination of the eye with a slit lamp, determination of visual acuity and determination of refraction (examination of the refractive properties of the eye); stereoscopic findings of optic disc (area of the retina where the retinal nerve fibers gather and form the optic nerve after leaving the eyeball) and peripapillary nerve fiber layer.
