Ophthalmoscopy: Examine the fundus of the eye (funduscopy)

The examination of the fundus of the eye is a most important diagnostic procedure.

With an ophthalmoscope it is possible to look through the pupil to the back of the eye and examine the retina , optic nerve, blood vessels and choroid.

With this examination, many eye diseases can be detected at an early stage. Serious diseases can thus be treated early and the chances of recovery increased. With the examination of the back of the eye, we examine the optic nerve head, the retina, the macula as well as the vitreous body.

Procedure of the ocular fundus examination

In order to have a better view of the back of the eye, the patient is given special eye drops in the office that temporarily dilate the pupils and allow the ophthalmologist to have a clear view. Then there are several methods of examination

  • With direct mirroring, the ophthalmologist can see the back of the eye greatly magnified through a so-called ophthalmoscope, so that even the smallest structures can be seen. However, only a small part of the eye fundus can be seen.
  • With indirect reflection, on the other hand, large retinal areas can be viewed. With the help of a special device, a three-dimensional image of the structures at the back of the eye can also be generated.
  • Contact glass examination is an examination method to view the retina in all areas and with high magnification. It is performed with the help of the slit lamp. The surface of the eye is superficially anesthetized with drops, as the ophthalmologist places the contact glass directly on the eye. In this way, for example, the angle of the anterior chamber of the eye can also be examined, which can be important for the diagnosis of glaucoma.

Anatomy of the human eye

Eye lens (lat. Lens crystallina)

The lens of the eye focuses the light entering through the pupil. With approximately 10 to 20 diopters of the eye's total refractive power (of about 63 diopters), the lens of the eye - along with the cornea ...

Lenticular bands (lat. Zonula ciliaris)

The lens ligaments - also called zonular fibers - are elastic fibers arranged in a spoke-like pattern around the capsule in which the lens of the eye is located. They hold the lens in position ...

External eye muscles

The external eye muscles are responsible for the movements of the eyes, i.e. changing the direction of gaze. They attach to different parts of the eyeball. Humans have four straight and two ...

Sclera (lat. Sclera) in the eye

The sclera forms the outermost layer of the eye, it is "the white of the eye" that can be seen from the outside around the pupil and iris. It is therefore also called ...

Choroid (lat. Choroidea)

The choroid is located between the sclera and cornea and extends over the entire posterior part of the eyeball. It has a high density of blood vessels and supplies the retina with ...

Blood vessels in the eye

While the retina is supplied by the choroid from one side, blood vessels also lie directly on the back of the eye - the retina. This network of vessels comes ...

Vitreous body (lat. Corpus vitreum)

The vitreous body fills most of the interior of the eye and thus sits between the lens and the retina. Consequently, light entering through the pupil and lens must pass through the vitreous before ...

Retina (lat. Retina)

The retina is responsible for converting light entering the eye into nerve impluses. The retina is very sensitive to light and lines the inside of the eye. It is the largest retina in the world with approximately 127 ...

Yellow spot (lat. Macula lutea) in the eye

The yellow spot is located in the center of the retina and is only about three to five millimeters in size. It gets its name from a yellow pigment that is found on this spot. ...
