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.
Rest and Recovery. Clean the hoof to remove any rocks that may be trapped. If a shoe is the cause of the bruise, remove it. Most bruises, especially stone bruises, heal on their own with approximately five to seven days of stall rest.You also can use a small paddock if the footing is not rocky.ost bruises heal on their own after a few days of stall rest, but you can consider additional treatment for severe bruising. Although bruises are not a serious or life-threatening condition, if your horse is lame consult a veterinarian to confirm the diagnosis and rule out more serious conditions such as laminitis.
