Clinical Analysis


Diagnóstico por la imagen

Aberrometry Examination which evaluates the aberrations of the eye.
Fluorescein Angiography A contrast (fluorescein) is injected to evaluate diseases of the fundus.
Autofluorescence Fundus photography with a special filter. The pupil must be dilated.
Indocyanine Green Angiography A contrast (indocyanine green) is injected to evaluate diseases of the fundus.
Biometry Eye size measurement, for Intra-Ocular (IOL) power calculation in cataract surgery.
B-Scan ultrasonography Fundus evaluation if it can not be seen in normal conditions.
Esthesiometry To test cornea nerve sensitivity.
Interferometry Testing of visual acuity to be reached after cataract surgery.
Confocal Microscopy (Cornea) Microscopic study of the layers of the cornea (CT scan).
Specular Microscopy (cell counting) Photograph of the corneal endothelium. To assess cell counts and morphological features.
ORA (Ocular Response Analyzer) Evaluation of flexibility and hardness of the cornea.
Pachymetry Study of corneal thickness.
GDx Polarimetry Count of the retinal nerve fibre layer.
Potential Acuity Meter (PAM) Testing of visual acuity to be reached after cataract surgery.
Pupillometry Measurement of the size of the pupil with photopic and scotopic conditions.
Retinography Fundus image.
Tear clearance test Schirmer strips placed in the fornix, indicating the relationship between production and loss of tears.
Osmolarity Test It measures the concentration of ions in the tear film. Diagnosis and management of dry eye syndrome.
Schirmer Test Evaluation of tear function.
Optical Coherence Tomography (OCT) Cross-sectional images of the retina, which allow the diagnosis of various pathologies.
Anterior Segment Tomography (Casia) Cross-sectional images of the anterior segment.
Glaucoma tomography (HRT) Topographic survey of the optic nerve (nerve fiber thickness, cup/disc ratio...).
Corneal topography Map of the cornea.
C-QUANT Assessment of straylight to detect defects in the transparent media of the eye (cornea, lens, vitreous).
