Nystagmus is a condition where the eyes make repetitive movements. The eyes can jerk exclusively in one direction, or make back and forth movements. With nystagmus, the eye can look jittery and can affect both eyes or just one eye.
Certain conditions can cause the eyes and even the skin to appear yellow. Yellowing of the eyes is typically a result of dysfunction of the liver, gallbladder, or pancreas. In some instances yellow eyes can involve multiple organs. Yellowing eyes are a symptom of a condition called jaundice. Jaundice occurs when the oxygen-carrying components (hemoglobin) in the blood are broken down into bilirubin and the bilirubin is not cleared normally. Bilirubin is supposed to move to the liver and then to the bile ducts and then released in the stool.
