When To Seek Medical Care
The next best step if possible is to find out what type of chemical you have been exposed to. You can look on the product label or call your regional Poison Control Center at 222-1222 to find out more information about a specific chemical.
If the chemical is an irritant and discomfort and blurred vision are only minor or nonexistent, then you may monitor your condition at home with a call to your eye doctor. Make sure the irritation does not worsen. If it does, call your eye doctor to arrange an appointment for that day or go to the emergency room of the nearest hospital.
If you have any question about the danger of a chemical, if you do not know what it is, or if you have significant symptoms, go immediately to the nearest hospital’s emergency room.
Any time you experience pain, tearing, redness, irritation, or vision loss, go to a hospital’s emergency room immediate evaluation, even if you believe the chemical is only a mild irritant.
All acid or alkali eye burns require immediate treatment and evaluation by a doctor. You should be taken immediately to the closest emergency room. If you suspect a serious injury may have occurred or are otherwise not able to make the trip to the emergency room quickly, then you should call an ambulance to shorten transport time. All industries are required to keep a Materials Safety Data Sheet on any chemicals being used. Find this information and take it with you.
Damage To The Eyelids Or Palpebral Conjunctiva
Direct chemical damage to the conjunctiva can lead to scarring, forniceal shortening, symblepharon formation and ciccatricial entropion or ectropion. These entities are encountered weeks to months after injury and can be treated by suppressing inflammation and with early amniotic membrane transplantation or oral mucosal graft.
What Are The Signs And Symptoms Of A Chemical Eye Burn
A true loss of vision signifies a very serious burn. Glaucoma, or an increase of the pressure inside the eye, can occur but may be delayed by hours to days.
Early signs and symptoms of a chemical eye burn are
- Inability to keep the eye open
- The sensation of something in the eye
- Swelling of the eyelids
- Blurred vision

Chemical Injury Causes Severe Corneal Scarring But This Can Be Prevented By Immediate Irrigation Of The Eye
If a patient has suffered a chemical burn in the eye, immediate, high-volume irrigation is essential in order to wash out the chemicals and save her or his vision.1
When taking the history, ask:
- When did the injury take place?
- Were the eyes rinsed out afterwards? For how long?
- What type of chemical splashed in the eye? Ask about the packaging
- Was she/he wearing eye protection?
- Accident or assault?
How Long To Use It For
Eye drops – use the drops until the eye appears normal and for 2 days afterwards. Do not use them for more than 5 days, unless your doctor tells you to. This is because your eyes can become more sensitive or you could get another eye infection.
Eye ointment – use the ointment until the eye appears normal and for 2 days afterwards. Do not use it for more than a week, unless your doctor tells you to.
Ear drops – use the drops for up to a week. Avoid using the medicine for longer than this unless your doctor tells you to. This is because your ears can become more sensitive or you could get another ear infection.
When you’ve finished your treatment, throw away any leftover eye drops, eye ointment or ear drops.

Can Corneal Abrasions Be Prevented
To help prevent corneal abrasions:
- Kids should wear eye protection, such as safety goggles or a facemask, when they work with tools, handle chemicals, or play sports where an eye could be affected. This includes sports like racquetball, skiing, snowboarding, hockey, and lacrosse.
- Be careful when playing with pets. Cats, dogs, and other animals can act in unpredictable ways and scratch an eye without meaning to.
- If your child wears contact lenses, make sure they fit well, and are worn and cleaned as directed. Keeping fingernails neatly trimmed can help prevent accidental scratches when putting in or removing contacts.
- If you have plants around your yard that someone could walk into, trim away any branches at eye level.
- If your child gets an irritant like soap or dust in the eye, be careful to avoid injuring the eye further. If anything is stuck in the eye, let a doctor remove it safely. Dont try to remove the object yourself. This could hurt the eye even more.
Do Any Of The Eye Medications Have Side Effects
A cat will occasionally be sensitive to ophthalmic medication. If your cat seems to be in more pain after the medication is used, discontinue it and contact your veterinarian.
A cat with a corneal ulcer normally has significant eye discomfort, so it keeps the eyelids tightly closed. Atropine relieves the pain but also dilates the pupil widely. This means that the cat is very sensitive to light in that eye and may squint or hold the eye tightly closed when exposed to bright light. The dilation of the eyes may last for several days after the medication is stopped.

Clinical Course: Grading And Staging
Efforts have been made to propose universal classifications of clinical findings that can be used reliably to predict outcomes. Grading refers to the severity of the damage and should be documented at the very first ophthalmic examination. The grading systems unify the corneal, limbal, and conjunctival changes to prognosticate the clinical condition and are very helpful to acquire a general idea of the interventions that may be recommended in later stages.
The first widely accepted grading system was published by Roper and Hall in 1965 . This grading system was based on the amount of corneal haziness and the proportion of ischemic perilimbal conjunctiva. According to the 4-step Roper-Hall classification, the prognosis of all patients with > 50% limbal ischemia was poor.
Other Eye Safety Suggestions
Important ways to reduce your risk include:
- know your chemicals check the chemicals label and its Material Safety Data Sheet for information on safe handling. Strictly follow the manufacturers instructions
- choose safer products hazardous chemicals can occasionally be replaced with less toxic options, or you may be able to buy the same chemical in a less dangerous form. For example, a liquid product may also be available as pellets
- keep safety equipment in good repair and easily accessible safety goggles and face shields need to be replaced regularly. Check the manufacturers guidelines
- dont wear contact lenses a contact lens may absorb the chemical and concentrate the burn on the eye surface. When working with chemicals, wear prescription glasses instead of contact lenses, and always wear protective equipment over the glasses
- dispose of unwanted chemicals safely visit the Sustainability Victoria website to look for chemical collection times and places around Victoria, or call .

How And When To Use Chloramphenicol
Chloramphenicol comes in different strengths. How you apply the medicine depends on what you’re taking it for and whether you’re using the eye drops, eye ointment or ear drops.
If you’re using 0.5% chloramphenicol eye drops, put one drop into the affected eye every 2 hours for the first 2 days. Then every 4 hours for the next 3 days, or as your doctor advises.
If you’re using 1% chloramphenicol eye ointment, apply it to the affected eye every 3 hours . Do this 3 to 4 times a day, or as your doctor advises.
With more severe infections, your doctor may recommend using eye ointment at bedtime and eye drops during the day. This is because the ointment sticks to the surface of the eye and eyelid and works while you sleep. The eye drops allow you to get on with your day as normal, as they don’t affect your eyesight.
If you’re using 5% or 10% chloramphenicol ear drops, put 3 drops into the affected ear 2 to 3 times a day, or as your doctor advises.
To use the medicine:
- always wash your hands before using chloramphenicol – this prevents you from passing the infection to the other eye or ear
- remove the cap just before using your medicine and replace it as soon as you’ve finished
- do not touch the nozzle of the bottle or tube with your fingers
- make sure the nozzle doesn’t touch your eye or ear, or your skin
- use a mirror to help you see what you are doing
- tilt your head back or to the side to put drops in your eyes or ears

First Aid Suggestions For Chemical Burns To The Eye
Liquid or powder splashes from chemicals may seriously damage the eye. In many cases, prompt and thorough rinsing of the eye , dramatically reduces the risk of injury and long-term damage. Its often better to go straight to the nearest tap than to wait for saline from the first aid kit.
First aid suggestions include:
- Hold your face under running water for 15 to 20 minutes and allow the water stream to flood into your eyes. Use your fingers to hold your eyelids apart .
- If you wear contact lenses, remove them as soon as possible.
- Seek immediate medical advice. Medical staff will need to know what chemical was involved, particularly whether it was acid or alkaline, liquid or powder.
- Do not judge the seriousness of your eye injury on the degree of pain. For example, alkali chemicals dont usually cause significant symptoms, but can seriously damage the eye.
- Powder or particulate chemicals can be particularly damaging since they are more difficult to flush out.
Corneal Flash Burns Causes
Radiation damage to the cornea leading to a flash burn can be caused by ultraviolet light from various sources:
- Sunlamp in tanning salon
- Blurry vision
- Sensation of a foreign body in the eye
In most cases, both eyes are involved, although the symptoms may be worse in the eye that received more ultraviolet radiation. This is very different from a corneal abrasion due to an injury, where, ordinarily, only one eye is involved.

Dry Eye Symptoms Are Often Different In Different People However The Following Are Commonly Experienced By Those Whose Tear Production Is Inadequate:
- irritated, scratchy, dry, or uncomfortable eyes
- excessive watering as the eyes try to comfort an overly dry eye
- redness of the eyes
- a burning sensation of the eyes
- the feeling of a foreign body in the eye
- blurred vision
- eyes that seem to have lost their normal clear glassy luster
If untreated, Dry Eye can be more than just irritating or uncomfortable. Excessive dry eye can damage eye tissue and possibly scar the cornea, the transparent front covering of the eye, impairing vision. Contact lens wear may be more difficult due to the possibility of increased irritation and a greater chance of eye infection.
Avoid over-the-counter EYE WHITENERS such as VISINE, CLEAR EYES, ALBALON, ALLEREST, ALLERGY DROPS, DEGEST 2, COLLYRIUM FRESH, COMFORT EYE DROPS, EYE GENE, ESTIVIN, ISOPTOFRIN, MURINE PLUS, PREFRIN, NAPHCON, OCU-CLEAR, RELIEF, 20/20 EYE DROPS, VASOCLEAR, VASOCON, AND ZINCFRIN.
These drops contain naphazoline, phenylephrine, tetrahydrozoline, or oxymetazoline and are not specifically for dry eyes. If you use these drops too often, they will lose their effectiveness and keep your eyes looking red. These drops are fine for occasional use to decrease redness.
What Is A Corneal Ulcer In Dogs
A corneal ulcer is essentially a severe wound on the cornea of the eye.
Ulcers on the cornea will erode through the epithelium and into the stroma, potentially leading to the cloudy appearance of the eye as a result.
You may not be able to see the corneal ulcer itself by simply looking at the eye, but you can see the injury when the eye is stained and examined thoroughly.
Corneal ulcers can continue to spread if they face continual irritation, leading to the possibility of erosion into the Descemets membrane.
If this occurs, a serious eye complication known as a descemetocele can form.
This condition can lead to eventual rupture of the Descemets membrane, causing the fluid of the eye to leak out.
If this occurs, most dogs will need to have the eye removed.

What Causes Corneal Ulcers
There are several causes of corneal ulcers in cats. The most common cause is trauma. An ulcer may result from blunt trauma, such as a cat rubbing its eye against a rough surface, or due to a laceration, such as a cat-claw scratch or contact with a sharp object such as a thorn. The second most common cause is chemical burn of the cornea. This may happen when irritating shampoos, other liquids, chemicals, or dust such as drywall dust gets in the eye.
“The most common cause is trauma.”
Other causes of corneal ulcers include bacterial infections, viral infections, and other diseases. These conditions may originate in the eye or develop secondary to disease elsewhere in the body. Examples of other diseases include:
- epithelial dystrophy rare in cats
- Manx stromal dystrophy corneal edema and serious eye abnormalities result in this disease which is believed to be inherited in Manx cats
- drying of the cornea due to decreased tear production, called keratoconjunctivitis sicca rare in cats
- endocrine diseases such as diabetes mellitus, and Cushing’s disease
