General Information
At Clínica Barraquer, we have state-of-the-art technology to perform precise diagnostic tests that allow our specialists to accurately assess the visual health of our patients.
Opening Hours:
Monday to Friday from 7:00 a.m. to 5:00 p.m.
Saturdays from 7:30 a.m. to 12:30 p.m.
Important Note
Some tests require special preparation. Please verify the specific requirements when scheduling your appointment.
Our Diagnostic Tests
We have a wide range of diagnostic tests to evaluate different aspects of visual health. Select a category to see the available tests.
Fluorescein Angiography
(Retinal Angiography or Retinofluorescein Angiography)
Imaging diagnostic technique that uses a fluorescent dye to visualize the blood vessels of the retina and choroid.
Retinography
(Posterior Segment Photography)
Detailed photograph of the retina to document and assess retinal diseases.
Macular Tomography
(Macular OCT or Optical Coherence Tomography of the Macula)
Exam that evaluates the structure and thickness of the macula through high-resolution images.
Optic Nerve Tomography
(Optic Nerve OCT or Optical Coherence Tomography of the Nerve)
Analyzes the optic nerve to detect structural damage, especially useful in glaucoma.
Optical Coherence Tomography (OCT)
(Corneal OCT or Optical Coherence Tomography for the Cornea)
High-resolution imaging of the retina and other ocular structures using infrared light.
Visual Field
(Visual Field Test or Campimetry)
Functional test that evaluates the patient’s ability to see across the entire visual field.
Standard Electroretinogram
(Full-Field or Monofocal Electroretinogram)
Measures the electrical activity of the retina in response to visual stimuli.
Multifocal Electroretinogram
Simultaneously evaluates multiple areas of the central retina, useful for detecting focal pathologies.
Pattern Electroretinogram
Analyzes the retina’s electrical responses to visual stimuli with specific patterns.
Electrooculogram
Measures the electrical potential generated between the front and back of the eye during eye movements.
Potential Visual Acuity Measurement
(Sweep)
Evaluates the patient’s visual potential, useful in cases with ocular opacities.
Visual Evoked Potential – Flash
Records the electrical activity of the optic nerve in response to brief light stimuli.
Visual Evoked Potential – Pattern
Evaluates visual function from the retina to the visual cortex using patterns such as squares or lines.
Color Test
(Farnsworth Test)
Test to assess color perception and detect chromatic vision disorders.
Biometry
Measures ocular structures such as axial length and anterior chamber depth, essential for cataract surgery.
Interferometry
Precise method to determine the eye’s axial length using light interference.
Pentacam
Three-dimensional tomography of the anterior segment of the eye with curvature, thickness, and anterior chamber depth measurements.
Corneal Tomography
Analyzes the cornea in sections to evaluate its structure and detect conditions such as keratoconus.
Computerized Corneal Topography
Detailed map of the corneal surface to detect irregularities and astigmatism.
Slit Corneal Topography
(SCT, Pachymetry, or Pentacam)
Technique for observing and mapping the cornea using a slit lamp.
MS-39 Corneal Topography
Advanced topography combining OCT and placido data for detailed corneal analysis.
Endothelial Cell Count
(Endothelium or Specular Microscopy)
Measures the number and morphology of corneal endothelial cells, useful in corneal diseases and preoperative evaluations.
Ocular Ultrasound
(Sonography, Sonogram, High-Resolution Anterior Segment Sonography, Ocular Ultrasound A & B Mode, Ultrasound Biomicroscopy (UBM) or Ocular Echography)
Ultrasound study to visualize internal eye structures when clinical observation is not possible.
Pachymetry
An ophthalmic test that measures corneal thickness, the transparent layer covering the front of the eye. This test is useful for diagnosing or monitoring various eye diseases and for evaluating a patient’s eligibility for refractive surgery.
Angiotomography
(Endovascular Optical Coherence Tomography, Macular Angiography, or Optic Nerve Angiotomography)
Provides detailed information about ocular blood circulation and perfusion without the need for dyes.
