Advanced Diagnostic Testing for Pet Eye Conditions
At Veterinary Eye Center - Pennsylvania, diagnostic testing plays an important role in identifying the cause of eye disease, tracking progression, and guiding treatment decisions. Our team uses a range of specialized ophthalmic diagnostics to evaluate vision, eye pressure, retinal health, corneal disease, and other ocular abnormalities in dogs and cats.

Our Diagnostic Tests
Companion Animal Eye Registry, or CAER, exams are performed by board-certified veterinary ophthalmologists to screen for inherited and breed-related eye disease. These evaluations can provide valuable information for breeders and owners who want to better understand ocular findings that may affect future generations.
In some cases, laboratory testing is needed to better define the cause of an eye problem. We may collect samples for cytology, culture, or biopsy when a lesion, area of inflammation, or abnormal tissue requires further evaluation. This type of testing can be helpful for chronic irritation, vision-threatening abnormalities, or findings that may be connected to broader systemic disease.
ERG measures the retina’s electrical response to light and can help determine whether the retina is functioning normally. This test is commonly used before cataract surgery and may also be recommended when retinal disease is suspected, including conditions such as SARDS.
Fluorescein stain helps evaluate the surface of the eye, especially the cornea. It is commonly used to identify corneal ulcers, assess areas of damage, and better understand how the tear film is protecting the eye.
Gonioscopy is used to examine the drainage angle within the eye. It can help determine the cause of glaucoma and may also identify whether the other eye is at risk, even if it appears normal during a routine exam.
Ocular ultrasound allows our team to examine structures inside and around the eye in a non-invasive way. It is often used before cataract surgery and can also help detect lens instability, intraocular masses, retinal abnormalities, and other internal eye changes that may not be visible on standard examination.
Adequate tear production is essential for eye comfort and corneal health. Tear testing gives us an objective way to measure tear output and is an important part of diagnosing and managing dry eye and related surface disease.
Tonometry measures pressure within the eye. This is a key test for pets with glaucoma, uveitis, or other conditions where pressure changes can affect vision and comfort.
Chromatic pupillometry is a non-invasive test that evaluates how the pupils respond to different colors of light. This information can help assess retinal and optic nerve function and may support the diagnosis or monitoring of diseases that affect vision.
Why Advanced Eye Diagnostics Matter
Not every eye condition can be diagnosed through a basic exam alone. Specialized testing can help clarify what is happening inside the eye, whether a disease is affecting vision, and which treatment options may be most appropriate. For families in Pennsylvania, this means a more complete understanding of their pet’s condition. For referring veterinarians, it means access to specialty diagnostic resources that can support efficient case management, treatment recommendations, and surgical planning when needed.
