Nystagmography refers to the examination of eye movements when nystagmus is suspected. This involves involuntary eye movements that can have a variety of causes. Nystagmus can be physiologic, but also pathologic.A distinction is made between rotational from spontaneous and positional nystagmus. Indications (areas of application) Suspicion of nystagmus and to clarify the cause. The procedure … Nystagmography
Optical coherence tomography (OCT) is one of the imaging modalities and is used in ophthalmology to examine the retina (retina), vitreous, and optic nerve (optic nerve). It is a noninvasive, noncontact method of producing optical, two-dimensional cross-sectional images that have high spatial resolution. Indications (areas of application) Macular hole – sharply defined destruction of the … Optical Coherence Tomography
The Optomap laser scanner is used in ophthalmology for diagnostic purposes. With this device, the retina can be visualized in great detail even through the narrow pupil. Indications (areas of application) Optic nerve damage Damage to the blood vessels supplying the retina, such as occurs with diabetes mellitus and hypertension (high blood pressure) Changes in … Optomap Laser Scanner
Orbscan topography (synonym: Orbscan I) is a modern procedure in ophthalmology that allows pachymetry (measurement of corneal thickness) and analysis of the anterior chamber structures of the eye (lens, iris). Corneal thickness is a parameter of tremendous importance and is used to determine corneal function. Indications (areas of application) Checking the function of the corneal … Orbscan Topography
The Retinal Thickness Analyzer (RTA) is an ophthalmology (eye care) vision diagnostic system used to determine retinal thickness, visualize the optic nerve, and view the subretinal layers (tissue located beneath the retina). The system is used for early detection of glaucoma (glaucoma – increase in intraocular pressure with accompanying deterioration of vision) and macular degeneration … Retinal Thickness Analyzer
Refractometry is a method of ophthalmology for objective visual acuity testing (visual acuity testing). It involves determining what additional refractive power is needed to obtain a sharp image on the retina. The human eye is shaped approximately like a sphere and contains a complex optical system. In emmetropia (normal vision), the eyeball is about 24 … Visual Acuity Test: Refractometry
Slit lamp or slit lamp microscope examination (synonyms: slit lamp microscopy; slit lamp examination) is one of the most important diagnostic procedures in ophthalmology. It is non-invasive (does not penetrate the body), easy to perform, and has a high information gain. Since the human eye is largely composed of transparent tissue, it is possible to … Slit Lamp Examination
Tonometry (synonym: intraocular pressure measurement) is a diagnostic procedure in ophthalmology for measuring intraocular pressure (intraocular pressure), which nowadays can be performed non-invasively (not penetrating the eyeball) using various techniques. In adults, normal intraocular pressure is between 10 and 21 mmHg. It is caused by a continuous flow of aqueous humor formed by the ciliary … Intraocular Pressure Measurement: Tonometry
Ophthalmoscopy (synonyms: funduscopy, ophthalmoscopy, ophthalmoscopy) is used to inspect the fundus of the eye and to detect any pathological (diseased) changes in the coroid (choroid), retina (retina), and optic nerve (optic nerve). The procedure dates back to Helmholtz, the inventor of the ophthalmoscope, in 1850. Today, modern ophthalmoscopes enable comprehensive and indispensable diagnostics in ophthalmology. … Ophthalmoscopy
Contact glass dynamometry is an ophthalmology (eye care) procedure for determining diastolic and systolic blood pressure in the eye. Furthermore, it is also possible to accurately determine the central venous pressure in the eye within a few seconds. With the help of this contact glass dynamometry procedure, an assessment of possible hypertension (high blood pressure) … Contact Glass Dynamometry
The Nerve Fiber Analyzer (synonyms: GDx, GDX analysis, GDX Nerve Fiber Analyzer, GDX Optic Nerve Fiber Analysis, Retinal nerve fiber analysis, GDx) represents a diagnostic imaging technique in ophthalmology and is used to examine nerve fiber thickness at the retina (retina). The Nerve Fiber Analyzer is particularly important in the early detection of glaucoma, a … Nerve Fiber Analyzer
The Retinal Vessel Analyzer (RVA) is used in ophthalmology for diagnostic purposes. This examination method can be used to examine the vessel width of the large retinal vessels (retinal vessels). Indications (areas of application) Hypertension (high blood pressure) Diabetes mellitus (diabetes) Obesity (overweight) Smoking Stress Lack of exercise Hypercholesterolemia (elevated cholesterol levels) Malnutrition Apoplexy (stroke) … Retinal Examination with Retinal Vessel Analyzer
