El ojo seco es una afectación ocular que puede tener causas múltiples, conocer el origen de la sintomatología es importante para abordar el tratamiento de forma correcta. En el Institut de la Màcula disponemos de una unidad especializada para la evaluación de las estructuras oculares que se ven involucradas en la producción y mantenimiento de […]
The slit lamp is a microscope with a light source that is essential for ophthalmologists. It allows for detailed visualization of the different structures of the eye and helps detect ocular diseases.

Gonioscopy is an examination performed to observe the iridocorneal angle. This angle contains the trabecular meshwork, which is the structure through which aqueous humor drains from the eye. If the angle is narrow or presents any structural abnormalities, it may hinder the outflow of aqueous humor, leading to increased intraocular pressure. The procedure is carried
Kinetic perimetry is a test that allows rapid and easy determination of the extent of a patient’s visual field. This test enables variation in the size and intensity of the stimulus, allowing adaptation to the visual function of each patient. It helps evaluate the level of involvement and progression of different pathologies such as retinitis
The electroretinogram (ERG) is a test that records and measures the electrical signal produced by the retinal cells (cones and rods) in response to a light or contrast stimulus. This test has significant clinical utility as it provides diagnostic information about various retinal pathologies, such as hereditary dystrophies, and can also be used to monitor

Perfecte, aquí tens només la traducció pura: AVOT (Advanced Vision and Optometric Test) is a tool for the automated measurement of visual acuity, positive and negative contrast sensitivity, and color vision together with cone and rod function. It allows us to evaluate visual acuity (VA) and Contrast Sensitivity Function (CSF) to establish normal or out-of-range
Intraocular pressure is the most important risk factor for developing glaucoma, so its measurement is essential. It is measured with the Goldmann tonometer, which assesses the cornea’s resistance to indentation.
Keratometry measures the radius of curvature of the cornea to determine the value of corneal astigmatism. This is the most significant type of astigmatism, but not the only one, as there is also astigmatism of the posterior corneal surface and of the anterior and posterior surfaces of the lens, which in many cases is minimal.
Corneal thickness is measured using pachymetry. Intraocular pressure measurement depends on corneal thickness. Patients with thicker-than-normal corneas tend to have higher intraocular pressure readings than actual, while those with thinner-than-average corneas tend to have lower readings than actual.
OCT angiography (OCT-A) is a new, fast, and non-invasive imaging modality that allows evaluation of the retinal microvascular network. OCT-A can provide a three-dimensional image of the retinal microvasculature and detect capillary abnormalities in patients with diabetic retinopathy and other retinal vascular diseases. With OCT-A, the superficial vascular plexus and the deep capillary plexus can
