Ophtalmology
Focal illumination – We use a connecting lens to focus the beam of light from the lighting lamp into the patient´s eye. This way, the anterior segment and the lens can be examined.
Examination with an eye mirror – This is a mirror with a small hole in the middle equipped with a holder. The light source is next to the patient. We throw light into the eye with a mirror and observe the pupil through the hole. Under normal circumstances, the pupils glow bright red, the so-called posterior eye reflex.
Ophthalmoscope – This is the examination of the eye with an eye mirror and the observation of the retina and choroid, the so-called fundus. We distinguish direct ophthalmoscopy, when we get a direct image magnified by about 16x, and indirect, when we insert a coupler between the ophthalmoscope and get an inverted image magnified by about 4x.
Biomikroskopy – When illuminated with a slit lamp, which has an illuminating and magnifying part, we mainly examine the front segment of the eye, the cornea and the lens.
Skioskopy – A method for examining the refraction of the eye as a whole, where we use an eye mirror and a set of lenses, which we tentatively place in front of the examined eye.
Refractometers – Devices for measuring the total refraction of the eye, they focus the image projected on the background of the eye.
Keratometers – Instruments for measuring the curvature of the cornea by the reflection of test lights on the cornea.
Computed Tomography CT – Provides accurate anatomical imaging of the eye in precise, detailed, computer-processed sections.
