Many eye injuries are preventable if you take appropriate safety precautions. The advice listed below can help reduce the risk of sustaining an eye injury.
Safety at work
To reduce the chances of eye injuries happening at work, always ensure that you follow health and safety guidelines. For example:
Symptoms
Superficial eye injuries are minor eye injuries, but because the area around the eye bruises particularly easily, they can sometimes look worse than they actually are.
Corneal abrasions
Symptoms of a corneal abrasion include:
Iritis (uveitis)
Symptoms of iritis include:
Foreign bodies
Symptoms of foreign bodies may include:
When to seek medical advice
Seek urgent medical advice if you have any of the following symptoms:
Causes
Eye injuries have a number of different causes, such as:
Blows to the eye
A blow to the eye can cause the following eye injuries:
Traumatic iritis - inflammation (swelling) caused by a blow to the eye from a blunt object, such as sports equipment or a fist.
Orbital blowout fracture - breaks or cracks in the bones of the face that surround the eye, which can push the eyeball further back into the eye socket (orbit).
Bleeding in the eye (hyphema) - can be caused by a blunt trauma to the eye, a sports injury, an industrial accident, a fight or a fall.
Retinal detachment - a rare condition that can be caused from a blow to the eye, or a complication of diabetes called diabetic retinopathy. It can result from tears and breaks in the retina, and lead to permanent vision loss if not treated promptly.
Foreign bodies
Foreign bodies, such as metal, plastic or wood, can scratch or graze the cornea (corneal abrasion). Examples of foreign bodies that can cause a corneal abrasion include:
Lacerations
A laceration (cut) can occur in the:
Eye lacerations can be caused by:
Ultraviolet light
Ultraviolet (UV) light can lead to an eye injury called ultraviolet keratitis or corneal flash burn. Exposure to the sun and sun lamps can cause of this type of injury.
Contact lenses
Wearing contact lenses incorrectly can also cause injury to your eyes.
Corneal abrasions (scratching or grazing of the cornea) are likely to occur if your contact lenses are not clean, do not fit properly or are worn for long periods of time.
It is also possible for a foreign body, such as a tiny particle of dust or dirt, to become trapped behind your contact lens and cause irritation to your eye.
Treatment - Self-help
If you have something stuck in your eye (a foreign body), or if your eye has been exposed to chemicals, you should wash your eye out using clean water, or a sterile fluid from a clear container. This will remove any loose material in your eye.
Flushing your eye
If chemicals are involved in the eye injury, flush your eye thoroughly using clean water or sterile fluid for at least 10 to 20 minutes. Use a lot of water to wash your eye, and gently hold your eyelids open throughout the rinsing process.
To flush your eye, you should:
The way that eye injuries are treated will depend on the extent of the injury, the symptoms and, in some cases, how the injury was caused. Infections from eye injuries are rare. However, eye infections can be severe, so it is likely that antibiotics will be prescribed in order to help prevent infection.
Referral to an eye specialist
You will need to be referred to an ophthalmologist (a specialist in eye conditions) for specialist treatment if:
Removing a foreign body
If there is a foreign body in your eye, such as a piece of grit, your GP or a doctor at the accident and emergency (A&E) department of your local hospital, may try to remove it. They will put anaesthetic eye drops in your eye first in order to numb it and prevent any pain.
The foreign body may be stuck underneath your upper eyelid, particularly if you can feel something there, or if you have scratches or grazes (abrasions) on the top half of your cornea (the transparent outer layer of your eye). If this is the case, it may be necessary to gently turn your eyelid inside out to remove the foreign body.
Once the anaesthetic eye drops have worn off, your eye may feel a bit uncomfortable until the abrasion heals. You may also be given antibiotic eye drops (chloramphenicol) to use for five days. This reduces the risk of infection.
If the cells that line the outer surface of your eye (epithelium cells) are damaged, you may be prescribed eye drops (cyclopentolate) that prevent pupil spasm (involuntary contraction) and give the cells time to heal. However, cyclopentolate is not usually recommended for women who are pregnant.
Treating eye pain
If your eye is painful, analgesics (painkillers) may be recommended in order to help reduce the pain. This will usually be in the form of paracetamol or ibuprofen.
However, ibuprofen should not be taken if you have certain medical conditions, such as asthma. Aspirin should not be given to children under 16.
Do not take aspirin for pain relief if your eye is bleeding because this will increase the risk of bleeding.
Preventing infection
In order to prevent infection in your eye after an injury, you may be prescribed a course of eye drops and ointment containing an antibiotic called chloramphenicol. Most people will need to take the eye drops four times a day and use the ointment at night before bedtime, for seven days.
However, you may not be able to take chloramphenicol if:
Using eye drops four times a day is not possible for you, for example, it interferes with work or school
You are pregnant or breastfeeding (or if you are trying to get pregnant)
You, or someone in your family, has had a condition that affects the components of your blood, such as aplastic anaemia (a lack of iron in the blood caused by toxins)
If you cannot take chloramphenicol eye drops, you may be prescribed eye drops that contain fusidic acid. These should be used twice a day for seven days.
If you usually wear contact lenses, you should not do so until your eye injury has completely healed. This is because some of the ingredients in eye drops can build up in the contact lens and cause irritation. If you are prescribed antibiotic eye drops, do not start wearing your contact lenses again until 24 hours after finishing your treatment.
If there is a large corneal abrasion present, you may be treated with eye drops (cycloplegia) as they can also prevent an eye spasm (involuntary contraction).
Using eye patches to cover a corneal abrasion is no longer recommended. This is because it does not reduce the healing time or reduce pain.
