How to Administer Eye Medications
If your pet has sustained an eye injury, has an eye infection or an internal medical condition that is affecting the eyes, or is recovering from eye surgery, it may be necessary for you to give one or several medications into the eye(s) to help with healing. At first the idea of one person giving eye medications to a wiggly pet may seem like a daunting task, but it is possible. Practicing the following approach should help you safely deliver the recommended eye medications.
Depending on the severity of the eye problem, one or more medications may have been prescribed for your pet. The first step in handling eye (“ophthalmic,” “ocular”) medications is understanding how much of each medication to give, when to give them, and which ones (if any) should be refrigerated. This information is on the label of most eye medications and can be explained to you by a veterinary technician if it is unclear. Eye medications may be prescribed to be used very frequently or much less so, ranging from 1 time daily to hourly, ideally equally spaced apart over time throughout the day. In some situations, continuing a schedule through the night may be important in the short term to prevent progression of an injury or infection and to potentially avoid eye surgery. In these situations, you should discuss with your veterinarian what the best schedule is before your pet leaves the hospital.
It is also common to need to place an Elizabethan collar (E-collar, “lampshade”) on your pet. This simple device can be tremendously helpful in protecting the eye from your pet’s desire to rub it, especially once it starts to heal and becomes itchy. These collars provide the best protection when they are worn 24 hours a day, since it only takes a few minutes to damage delicate tissue that has taken days to heal.
With medium- or long-nosed dogs, an E-collar can be kept on when administering eye medications, but with short-nosed dogs and many cats, it is easier to remove the E-collar and then replace it after giving the medication.
If your pet is extremely energetic or has a small face or short snout, it may be more difficult for you to get medications into the eyes. At first, it may be helpful for you to have a second person available to help hold the pet still. If you are applying more than one kind of drop, or both ointment and drops, then be aware of timing and order of administration. Drops are always first, and ointments are always last; otherwise the ointment can create a barrier that prevents the drops from working. To allow absorption of each medication, it is ideal to leave 5 minutes between giving each medication. Allowing for extra time in your daily routine to accomplish this type of schedule is almost always necessary. In some cases, this is temporary (if the injury or disease is cured), whereas in other cases this type of treatment continues long term or permanently. You can ask your veterinarian about what is expected in terms of having to continue to give ocular medications.
PROCEDURE FOR ADMINISTERING EYE MEDICATION
First, situate yourself so that you can hold your pet’s head. For cats and small dogs, this means putting them on your lap or placing them on a table. For medium and large dogs, this means kneeling down or arranging them so their hind end is between your knees or ankles while you are standing. This approach should also help keep them still.Second, lift your pet’s head so the eyes and nose are pointing as straight upward as possible, ideally toward the ceiling. For a right-handed person, this is done using the left hand.
Hold the bottle or dropper like a pencil in your right hand, and use the edge of your right palm to slide back the skin above the upper eyelid. This will lift the upper eyelid and expose the eye. Use the thumb or middle finger of your left hand, which is still elevating the chin to keep the head pointing toward the ceiling, to draw down the skin below the lower eyelid, further parting the eyelids and opening the eye. Without allowing the applicator tip to touch the surface of the eye, bring the bottle/dropper close to the eye, and squeeze the bottle such that a drop of the liquid medication falls onto the eye surface.
Using the same approach described for drops, squeeze approximately a 1/4-inch strip of ointment from the tube, and drape this strip of ointment across the surface of the eye, again taking care not to touch the eye with the applicator tip. a When finished, close the eyelids, and gently massage the strip of ointment over the surface of the eye unless the eye is fragile or just had surgery.Some surgeries to the eye require that the lids are temporarily secured closed with sutures (stitches). Some infections or traumatic injuries cause massive swelling to the eyelids. In these cases, sometimes only a small portion of the eye can be seen. Often, the visible portion of the eye is the corner near the snout. In giving eye medications in these situations, the approach described above can still be used, but the drops or ointment are placed in the corner of the eye. Drops should run across the eye (under the eyelids) easily on their own. Normal movement of the eye will help distribute ointment.
If you find that it is only possible to give eye medications by first removing your pet’s E-collar, be sure to protect the eyes from rubbing against the collar when you remove or replace it. For example, if you slip the collar over their head without taking the collar completely apart, you should hold your hand over your pet’s eyes as you slide the collar back into place. This will help prevent damage to the eye(s).
FREQUENTLY ASKED QUESTIONS
Each morning my pet’s eye has dried discharge on it. Is that a problem?
A small amount (dry rice grain size or less) of black or yellow material is normal. Larger amounts are common with recovery from infection, traumatic injury, or surgery. If it is dried and caked, it should be removed to prevent a deeper infection. Hold the corner of a clean washcloth soaked with lukewarm water on the dried material to help it soften. Then gently wipe it away.
My pet had an infection in one eye, but now the other eye looks red/itchy/has discharge. What do I do?
This could be evidence that the infection has spread to the other eye. However, there are other explanations (such as dry eye, allergy flare-ups, or intraocular disorders) that can masquerade as a spreading infection. You should call your veterinarian or schedule a recheck appointment to determine the appropriate treatment.
I simply cannot get the medication in the eye. My pet shakes away, and I am afraid I will cause more harm than good. What do I do?
There are some oral medication substitutes (syrups, tablets, etc.) and some injections that can help with certain eye problems. Above all, the first rule is to do no harm: if you are concerned you may hurt your pet—or may get hurt (e.g., bitten)—then do not administer the medication, but do call your veterinarian back the same day to make an appointment and review whether there is a different technique, or a different form of medication altogether, that is preferable.
