Blindness in Dogs Page 2
Veterinary care should include tests to establish a diagnosis and subsequent treatment. Diagnostic tests are essential in determining the exact cause of the blindness. Tests may include: Complete physical examination and history Complete ophthalmic examination, including direct and indirect ophthalmoscopy, pupillary light reflex testing, slit-lamp biomicroscopy, tonometry, Schirmer tear testing, navigation of the pet through an obstacle course, visual tracking and visual placing tests, and fluorescein staining of the cornea. Complete neurologic examination
Other Diagnostic Tests Complete blood count (CBC) and serum tests via blood samples Blood pressure testing Electroretinography to evaluate the electrical responses of the retina to light stimulation Visually evoked response test to detect abnormality within the optic nerve or visual center of the brain Specific serologic tests to evaluate the cause and identify any related problems Corneal and conjunctival cell samples for cell analysis and specific tests to determine the presence of infection or inflammation Specialized imaging tests of the eye and skull, such as ultrasound examinations, MRI (magnetic resonance imaging) or CT (computed tomography) scans Cerebral spinal fluid tap to collect a sample of fluid surrounding the spinal cord and brain with a small needle
Successful treatment depends on obtaining an accurate diagnosis.
