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.
Although first aid is helpful, it is difficult for a non-professional to know the extent of damage to the eye. Medical care must be obtained quickly. Give first aid then seek medical care for eye injuries.
When an eye or eyelid is cut, bandage the eye lightly and seek medical care right away. Do not try to wash out the eye or remove any objects stuck in the eye. Do not rub or apply pressure to the injured eye or lid.
Treat a blow to the eye immediately with an ice compress for about 15 minutes. This reduces pain and swelling. Black eyes or blurred vision may indicate damage to the contents of the eye. If the eyes come in contact with caustic chemicals, begin first aid immediately by flushing the eye with water for at least 15 to 30 minutes. Open the eye as wide as possible using your fingers to spread the lids. While flushing the eye, have the patient roll their eye as much as possible to clean all surfaces. Do not use an eye cup or bandage the eye.
Eye symptoms vary from a slow, gradual onset to a sudden problem. Seek medical care for any change in the condition of your eyes or sight. Proper evaluation and treatment are crucial to healing and preventing blindness.
