Ophthalmoscopy

Keeping an overview with ophthalmoscopy

The ophthalmoscope is a device used in the field of ophthalmoscopy. These medical devices are used to examine the back of the eye, more precisely the inner surface of the eyeball. The ophthalmologist uses this light source to observe the ocular cavity through the pupil to make a diagnosis. During this examination, the retina, choroid and pupil are clearly visible and can be examined in great detail. In the following we will explain the difference between direct and indirect ophthalmoscopy.

Direct ophthalmoscopy

In direct ophthalmoscopy, the ophthalmologist uses an ophthalmoscope (an electric eye mirror) to look into the patient's eye. He obtains an image with a magnification of 14 to 16 times. This method is relatively simple to perform and is particularly suitable for examining the exit point of the optic nerve, the macula and the central blood vessels, among other things. The disadvantage of direct fundus observation is that it only shows a small part of the fundus, but with high magnification.

Indirect ophthalmoscopy

During indirect ophthalmoscopy, the patient stares at a point above the doctor's head. During this time, the doctor holds a converging lens in front of the patient's eye with an outstretched arm, using a binocular ophthalmoscope attached to the forehead as the light source. The hand with the lens will rest on the patient's forehead. In the other hand, the ophthalmologist uses an additional light source to illuminate the eye to be examined. Good lighting is highly recommended, as it makes many small vessels visible. This method, unlike direct ophthalmoscopy, allows for a large field of view, but only with a magnification of 4.5 times. In addition, with indirect ophthalmoscopy, the image is upside down, which is why this method is also called "reverse image" fundus examination.

Restrictions and obstacles

Ophthalmoscopy with an ocular mirror cannot be performed on all patients. An unobstructed view of the eye must be guaranteed, which is not the case for some patients with the following clinical signs: opacity, cataract or vitreous hemorrhage. Abnormalities compromise the proper performance of ophthalmoscopy. In difficult cases, the pupil can be dilated with a special eye drop to get a better view. In this way, the edges of the retina are easily recognizable.
