Some ophthalmological conditions require a more in-depth diagnostic approach. At Vetvisão, we offer a wide range of advanced ophthalmic diagnostic procedures that play a crucial role in accurate diagnosis and treatment planning.
Gonioscopy
Gonioscopy is an examination that allows the evaluation of the iridocorneal angle. Using a specially designed lens, we assess this structure and obtain essential information about aqueous humor outflow.
This examination is fundamental for the accurate diagnosis of glaucoma, allowing differentiation between primary glaucoma and glaucoma secondary to other ocular or systemic conditions.
Ocular Ultrasound (A-mode and B-mode)
Ocular ultrasound, performed in both A-mode and B-mode, provides detailed images of internal ocular structures. This technique is particularly useful in patients with compromised transparency of the ocular media, where routine ophthalmological examination is not possible.
This exam is painless, safe, and allows comprehensive evaluation of the eye’s internal anatomy.
Electroretinography (ERG)
Electroretinography evaluates the electrophysiological function of the retina in response to light stimuli. Using scotopic and photopic protocols, we obtain detailed information about the function of retinal photoreceptors: cones and rods.
Cones are responsible for color vision and function in bright light conditions, while rods are essential for vision in low-light environments.
Ultrasound Biomicroscopy (UBM)
Ultrasound Biomicroscopy (UBM) provides high-resolution images of the anterior segment of the eye. This advanced technology uses high-frequency ultrasound waves, allowing detailed evaluation of intraocular structures with exceptional precision.
This painless examination produces real-time images of the cornea, iris, ciliary body, and iridocorneal angle.
Corneoconjunctival Cytology
Corneoconjunctival cytology involves the collection and microscopic analysis of cells from the cornea and conjunctiva. This examination allows the detection of microorganisms, inflammatory cells, and neoplastic cells.
Microbiological Cultures and PCR
Samples collected from the conjunctival sac or cornea may be submitted for microbiological cultures and polymerase chain reaction (PCR) testing. These tests allow the identification of specific infectious agents responsible for ocular disease and are essential for targeted and effective treatment.
Ocular Biopsy
An ocular biopsy involves the collection of small tissue samples for microscopic examination. This procedure is essential for diagnosing complex conditions such as neoplasia and certain inflammatory diseases.
Histopathological analysis provides a definitive diagnosis and is fundamental for guiding treatment decisions and prognosis.
OSA-Vet
OSA-Vet is an advanced ocular surface analysis system recently introduced at our clinic. This device enables an objective evaluation of the tear film, including tear quality and stability, as well as the ocular surface.
This technology is essential for the diagnosis and monitoring of conditions such as dry eye disease, supporting more accurate and individualized treatment planning.
