People who have
sickle cell disease can sometimes have vision
problems. Blood cells that change shape or "sickle" can get trapped in blood
vessels, blocking the blood flow. When this blockage occurs in the small blood
vessels in the inner lining (retina) of the eyes, it can cause
vision problems. This most often occurs in people who have hemoglobin SC
disease, a type of sickle cell disease.
In the worst cases, the
retina may come loose, leading to permanent blindness.
