Arteries turn into smaller arteries called arterioles. Blood reaches the ocular tissue through the capillary beds, and then returns to the heart through veins. The eye contains hundreds of millions of specialized nerve cells, specifically rods and cones. Cones are responsible for color vision and detailed vision and function best under bright illumination. The pupillary response to bright light is to constrict to prevent excessive light from entering the eye.
Blood flow is reduced when constriction occurs.
882-7000 to make an appointment with a University of Missouri Health Sciences Center physician. I had surgery for nasal polyp removal about one month ago. I had a complication post op, and after two MRIs and two CT scans I learned that my left medial rectus muscle was injured during the operation. I have diplopia but only the right side is affected. I also have severe headaches.
