Ocular ultrasound is an examination used to observe the eye area and measure its size and structure. It is employed to detect retinal or vitreous detachment, intraocular hemorrhages, lens abnormalities, presence of foreign bodies, and ocular tumors. It also allows analysis of the ocular muscles and the retrobulbar region. To perform ocular ultrasound, high-frequency sound […]

Visual field testing is an examination used to assess alterations in the visual field (the portion of space the eye can perceive while focused on a central point). This test detects any loss of peripheral vision and produces a map of this loss, which guides and assists in diagnosing certain pathologies (glaucoma, retinal diseases, optic

Optical coherence tomography (OCT) allows us to obtain high-resolution cross-sectional images of the anterior and posterior segments of the eye non-invasively, using optical interferometry. It has become a very useful tool for the ultrastructural study of ocular anatomy. Anterior segment OCT is used to monitor patients who have undergone refractive surgery, intracorneal ring implants, corneal

Corneal topography performs a systematic analysis of the cornea, allowing a thorough understanding of its shape. Modern topographers incorporate projection systems (Placido discs) and elevation measurements to provide a more complete analysis of the anterior and posterior corneal surfaces. Currently, one of the most important applications of corneal topography is the early detection and monitoring

Microperimetry is one of the most specific tests to determine central vision defects and the extent of damage caused by certain diseases such as age-related macular degeneration, diabetic retinopathy, diabetic macular edema, and central serous retinopathy. Microperimetry is a non-invasive technique that maps the macular visual field. It is performed first on one eye and

Indocyanine green angiography is a diagnostic procedure that uses a specific dye (indocyanine green) to detect leaks or damage in the blood vessels that supply the retina. Indocyanine green exhibits its characteristic staining properties when exposed to invisible infrared rays. Performing this examination requires sophisticated cameras sensitive to these light wavelengths. This angiography is used

Fluorescein angiography is a diagnostic procedure (similar to retinal photography) in which a special camera takes a series of photographs of the light-sensitive tissues at the back of the eye. As its name suggests, the procedure involves the use of a special dye called sodium fluorescein, which is injected into the patient and travels through

Retinography is a diagnostic test that captures an image of the eye’s fundus or retina, similar to photography. This procedure helps detect various retinal diseases such as age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa. Retinography requires only the application of eye drops to dilate the pupil and is a simple, painless, useful, and safe

Fundus autofluorescence imaging is a non-invasive technique that provides detailed information about the onset and progression of disease. The autofluorescence technique utilizes the fluorescent properties of a metabolic indicator called lipofuscin to study the health and viability of the retinal pigment epithelium (RPE) complex. While other fluorochromes can be detected in the outer retina in

Optical coherence tomography (OCT) is a non-invasive optical tomographic imaging technique (sectional imaging) that uses a combination of light sources from various detectors to achieve higher resolution. The millimetric penetration of this technique provides high-resolution images of the different retinal layers. The latest generation technology available at the Institut de la Màcula allows identification of
