Demanding Immediate Attention Eyes are our organs of sight. The eye is a complex structure that receives and translates light into impulses that our brain recognizes as images. Vision provides much of our daily sensory input. It is important for us to be aware of symptoms that indicate a potential threat to our vision.
Many medical problems can cause loss of sight.
Eye disorders such as cataracts, glaucoma or detached retinas may lead to eventual blindness. Illnesses such as diabetes or hypertension can also contribute to a decrease in vision. Some visual changes may be caused by a problem in the brain. Others may be related to medication toxicity or nerve or muscle diseases. In the event of an eye injury, prompt and accurate eye care can prevent a loss of sight.
