Keratoconus causes the middle of the cornea to thin, bulge outward, and form a rounded cone shape. This abnormal curvature of the cornea can cause double or blurred vision, nearsightedness, astigmatism, and increased sensitivity to light.
Bruises develop when small blood vessels under the skin tear or rupture, most often from a bump or fall. Blood leaks into tissues under the skin and causes the black-and-blue color. As bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green. Sometimes the area of the bruise spreads down the body in the direction of gravity. A bruise on a leg usually will take longer to heal than a bruise on the face or arms.
How long it takes a facial fracture to heal will depend on the type and extent of fracture and what other problems and treatment you had. Bruising and swelling usually takes 2 to 3 weeks to settle down. At this point, you will begin to look more normal. After this time the body will continue to heal itself inside. Unfortunately, you will need to be a patient.
