Specialised equipment is used to examine your animal’s eyes. The front of the eye is examined with a slitlamp biomicroscope. This instrument provides a very good light source as well as good magnification. The retina and optic disk are examined with both direct and indirect ophthalmoscopes. Other diagnostic procedures include tonometry to determine the pressure in the eye; gonioscopy to examine the drainage angle of the eye; cytology to examine conjunctival and corneal cells; Schirmer tear test to measure the tear production; and ophthalmic dyes to assess corneal integrity.
Ultrasonography enables the examiner to visualize structures both within and behind the eye. This is particularly important in ocular conditions that make ophthalmoscopic examination difficult and in cases where there is pathology behind the eye.
Electroretinography allows one to measure the electrical activity within the retina and thereby assess it’s functional integrity. This procedure is performed on all our cataract patients to ensure normal retinal function before cataract surgery.
The Johannesburg Animal Eye Hospital is fortunate to be able to use the resources of a specialised radiography and imaging practice at a local medical hospital for all our magnetic resonance imaging (MRI). This form of advanced imaging allows us to investigate problems such as tumours found behind the eyeball and within the brain.
A local medical oncology centre also assists us with advanced radiation techniques for patients that have sun-induced skin cancer. This is proving to be a very satisfactory method of managing these patients.
South African Veterinary Association (SAVA) Eye Certification Scheme
We are affiliated to the SAVA eye certification scheme. It is highly recommended that animals used for breeding be tested for hereditary eye diseases. Such tests assist in reducing the incidence of hereditary conditions which could lead to visual problems.
Horses and game animals
For the examination and admission of horses we make use of two equine practices in the Kyalami / Midrand area. All general anaesthetic procedures performed at these facilities are under the strict supervision of equine veterinarians. Equine consultations can also be accommodated at our branch clinic at the Onderstepoort Veterinary Faculty near Pretoria. We are also frequently called upon to do private equine and game consultations.
Our theatre is well equipped with state of the art ophthalmic equipment including an operating microscope, phacoemulsification unit, electroepilator, blood pressure monitoring devices and specialised surgical instruments. We make use of very safe intravenous and gaseous anaesthetic agents. All anaesthesia is monitored using specialised monitoring equipment. Fine attention is given to both pre and post operative pain management.
