ANIMAL EYE CARE REFERRAL FORM
We have a referral form for your convenience. It provides space for you (the referring veterinarian) to provide information about your patient, as well as a map with written directions to Animal Eye Care (AEC). Please call us to request copies of this form by mail or simply click below for a printable version. We would also be happy to send you brochures and business cards.

HOW WE WORK
At Animal Eye Care we strive to stay as available as possible to the
referring veterinarian. We see ourselves as a resource and want you to ask
us questions, seek advice from us on difficult cases and to refer those
cases when necessary. Our policy, concerning referrals, is that if either an
owner of an animal, or you, as a referring veterinarian, feel that a case is
an emergency, we will consider it one as well and will see it immediately or
suggest an alternative. We will fax you a letter with a summary of the case
on the day we examine the patient.
CARE & USE OF THE SCHIOTZ TONOMETER
HOW TO USE THE SCHIOTZ TONOMETER
Tonometer should be cleaned, using water and alcohol, and taken apart after every use. A pipe cleaner (usually provided) is needed to clean inside the tonometer.
Use the stainless steel "eye" provided to zero the tonometer before use.
Apply a drop of topical anesthetic to the animal's eyes.
Position the animal either sitting with nose pointing directly upward or on its back.
Optimal use of the Schiotz tonometer requires 2-3 people: one to hold the dog in position, a second to hold the base of the tonometer in contact with the cornea, and a third to read the scale.
Do not squeeze the animal around the neck in restraint, as this will increase intraocular pressure.
Make sure the base of the tonometer rests gently on the cornea and is not tipped. The tonometer should be vertical.
Do not press on the cornea; let the tonometer rest as if you were about to let it go.
Use the chart that comes with the tonometer.
Rule of thumb: in a normal eye the scale reading will be plus or minus "2" from the weight on the tonometer, i.e. for a 5.5 gram weight, the scale should be 3.5 to 7.5 to put the intraocular pressure in the normal range. With the 7-gram weight, normal would be 5 - 9 on the scale.
Remember that a high scale reading indicates a low intraocular pressure and a low scale reading indicates a high intraocular pressure. The stainless steel "eye" provided in the tonometer case represents a very hard eye and should be 0 on the scale.
Be careful not to cause corneal ulceration. Glaucomatous eyes often have corneal edema and the corneas can be very fragile.
The Schiotz tonometer works by indenting the eye with weight. It should not be used on eyes that have had recent intraocular surgery or that have deep ulcers that could perforate.
CARE OF THE SCHIOTZ TONOMETER
The Schiotz Tonometer measures intraocular pressure by registering the depth of indentation produced in the cornea by a plunger carrying a known weight. The downward movement is multiplied twenty times, so each division on the scale corresponds to an indentation of 1/20 mm in the cornea.
A test block is provided to check the 0 setting. Insert the plunger in the tonometer; screw the 5.5g weight onto the threaded top of the plunger. Gently set the footplate on the test block to obtain a zero reading on the scale. Make sure the end of the plunger and the footplate are clean before testing.

CLEANING THE SCHIOTZ TONOMETER
The tonometer must be kept clean at all times. Foreign matter may not only affect the accuracy of the readings, but also add to the possibility of transfer of disease from one patient to another.
After using the tonometer for each patient the tonometer must be cleaned. Remove the plunger from the cylinder. Wipe the plunger clean with alcohol to remove any residue of salt from tears. Allow the parts to dry and store the plunger and tonometer in the closed carrying case. Avoid the adhesion of lint or any other foreign matter in the tonometer. Do not attempt to oil or lubricate. Any oily residue will affect the operation.
To clean, unscrew the 5.5g weight from the plunger, withdraw the plunger and rinse it clean. The bore of the cylinder above the footplate should be flushed using a syringe or other method you find convenient to remove any residue form tears.
The use of alcohol will help dry the instrument, particularly in the cylinder bore. The plunger and footplate may be wiped dry with a lint-free cloth or gauze. Before storage, all areas should be clean and dry to prevent oxidation. Keep all parts free from lint and store the tonometer in its carrying case.
On a regular basis, when checking the zero setting on the test block, make sure the tonometer is free from friction. The plunger with 5.5g weight should slide freely in the cylinder bore as the tonometer is gradually rotated from a horizontal to a vertical axis. Movement of the plunger should begin after a rotation of not more than 25 degrees from the horizontal axis. Then test for freedom of movement of the needle throughout the scale range on the dial. Although slight hesitation on either stop pin is normal, movement must be completely free throughout the scale range.
