Diagnosis of diabetic retinopathy at the ophthalmologist

In the initial phase, diabetic retinopathy shows no symptoms to the patient, so an early diagnosis by the ophthalmologist is only possible through regular preventive examinations. We offer various options for examining the eyes of diabetics in order to be able to make a reliable diagnosis.

The diagnosis of diabetic retinopathy

We recommend high-risk patients, such as diabetics, to have an ophthalmologist check regularly. This enables an early diagnosis and subsequent treatment. In this way irreparable damage can be avoided. We use state-of-the-art medical technology to carry out preventive examinations, as well as to diagnose and, if necessary, treat retinal changes caused by diabetes in all stages.

The following examinations for the detection of diabetic retinopathy are available:

Optical coherence tomography (OCT)

To visualize the individual central retinal layers, we use the non-contact and non-invasive examination method called optical coherence tomography. With this examination we can see detailed findings that cannot be seen with the usual methods. The extent of macular edema can be shown precisely and the course of the disease can be followed precisely. In this way we can also determine whether there is a need for renewed treatment.

OCT - Optical Coherence Tomography

Optical coherence tomography angiography

OCT angiography is also a modern, non-invasive method and enables the representation of the small retinal vessels in the area of the macula and in the adjacent area of the retina. In the case of diabetic retinal changes, it enables us to visualize small microaneurysms (vasodilatation), pathological neovascularization and vascular-free areas (in so-called ischemic maculopathy). The use of dye injection is not necessary. In some cases, this examination method is well suited for diagnosing and monitoring the progress of diabetic retinal diseases.

Optical coherence tomography angiography

Fluorescence angiography (FLA)

If detailed information about the blood flow to the entire retina is required, fluorescence angiography is performed. This examination method is suitable, for example, for the stage of proliferative diabetic retinopathy, both for diagnosis and later follow-up. A well-tolerated yellow dye (fluorescein) is injected into the arm vein and is distributed throughout the body, including the fundus vessels. These vessels are then photographed over time by a special camera. Many pathological changes, such as the formation of new vessels in proliferative diabetic retinopathy, can be made visible in this way.

Fluorescence angiography (FLA)

Fundus photography and wide-angle images of the retina

The wide-angle view of the retina is made using a special camera. It is possible to partially take the exposure without dilating the pupils. Pathological changes such as bleeding can thus be precisely documented. The image material can be very helpful later as a follow-up control.

Non-proliferative diabetic retinopathy (NPDR)

Don't be afraid of the ophthalmologist!

Our ophthalmological practice specializes in the detection and treatment of diabetes-related eye diseases. We use the latest technologies in ophthalmic medicine, work very sensitively, absolutely sterile and particularly precise, so that examinations and treatment can be experienced quickly and painlessly
