Plain-English summary
A new type of high-frequency ultrasound probe, which operates at 20 MHz, can take very detailed images of the front part of the eye in pets. This technology allows veterinarians to see tiny structures clearly, helping them tell apart conditions that might look similar but need different treatments, like certain eye tumors and cysts. It can also assist in planning surgeries for eye problems where the cornea is cloudy, such as in cats with corneal sequestrum or tumors. Additionally, this ultrasound can help understand how glaucoma develops in pets and examine parts of the lens that are hard to see directly. Overall, this advanced ultrasound is a useful tool for diagnosing and treating eye issues in animals.
Abstract
The recent development of a 20-MHz, high-frequency ultrasound probe has allowed tissue to be visualized at resolutions of 20 to 80 microm, which is similar to a low-power histologic view. This high degree of resolution, however, limits tissue penetration to 5 to 10 mm, which is ideal for examination of the anterior segment of the eye. The detail provided by high-resolution ultrasound readily permits the clinician to distinguish between various anterior segment entities that may appear similar but are treated quite differently, such as anterior uveal tumors, iridociliary cysts, and iris bombé. High-frequency ultrasound is also a valuable aid in creating a surgical plan for treatment of ocular disorders in which the cornea is opaque, such as feline corneal sequestrum and tumor invasion into the cornea. Other applications of this technology include elucidation of the pathogenesis of glaucoma in veterinary patients and evaluation of regions of the lens that are difficult to examine directly.
