Verticillata: 54-year-old white male with a known history of atrial fibrillation and hypertension on amiodarone.
The cornea consists of unmyelinated nerve endings that are sensitive to various stimuli such as touch, changes in temperature, and chemicals. If the eyelids are open, the cornea is subject to the cold air in the environment that easily dries the eye. These tears may come from injuries caused by scratches from glass particles in the eye, or metallic particles also. The reason why it is transparent is because it has no blood vessels; it receives nutrition though from the nutrients from the tear fluid in the outside and the aqueous humor through the inside surface as well as from the neurotrophins coming from the nerve fibers that innervate the cornea.
