Back from the summer holidays?
You are stored sun energy. GETOCT.

Try to catch the sun, the sun has taken you long before. Your body is stored sun energy! Sunset in Zadar at the adriatic coast 2012. »Zadar has the most beautiful sunset in the world, applauded at every evening.« Alfred Hitchcock, May 1964, from room 204, Zadar/Croatia.

You are stored sun energy!
Plants convert electromagnetic energy directed from the sun into biochemical energy and store it into sugar. Your body converts this chemically stored energy back into electrical power at a cellular level. You can stretch your hand to the sun to capture it, but from the first day of your life, you already have the solar energy in yourself. You are connected to the sun, your body is nothing more or less than a sun storage. In diabetes, the use and flow of this energy storage is disturbed. Yours Peter Maloca, MD.

What to do in diabetic retinopathy? by Martin K. Schmid, MD

The strategies change, new knowledge has to be evaluated and proofed. The findings of today may already be obsolete tomorrow. We can only show a snapshot of the current knowledge about diabetes. General recommendations must always be placed in the context of the affected patient. There is no standard diabetes patient, each person is different, everybody needs a customized procedure.

Basic frame:
It sounds simple but first of all: the basic frame of all diabetic problems, is the diabetes itself. Diabetic retinopathy represents “only” the complication of the underlying disease, called diabetes. Good interdisciplinary management of the underlying disease means control and treatment of the most important paramaters. Responsible for the treatment and control of the underlying disease are the internist and the patient together.

How should we monitor patients with diabetes?
It is important to know that after 20 years, more than 80 percent of affected patient develop a diabetic retinopathy. There are mainly the situations:

1. Pregnancy:

Pregnancy can be a source of danger in diabetes. Pregnancy can lead to a diabetes decompensation. A baseline checkup should already occur if a desire for pregnancy exists. During pregnancy the patient should be checked every three months, even monthly in special cases.

2. Type 1 diabetes:
Currently it is recommended in type 1 diabetes: annual check from the fifth year of manifestation, or from the age of eleven. In the presence of type 1 diabetes without retinopathy annual inspection should be performed. In the presence of type 1 diabetes with retinopathy, the procedure corresponds to the severity.

3. Type 2 diabetes:

In type 2 diabetes, it is different because at diagnosis 36 percent already show a retinopathy. If the retina is healthy in diabetes type 2, nevertheless the retina should be examined annually.
In diabetes with a healthy retina or only a few microaneurysms an annual inspection is recommended.
A moderate diabetic retinopathy means only a few hemorrhages, microaneurysms, beaded veines. In question of an ischemia a fluorescence angiography is worthwhile.  An OCT may be helpful in a decrease of visual acuity with looking for a macular edema.
The checks are carried out every 6 to 12 months depending on the situation.

An advanced diabetic retinopathy is characterized by the 4-2-1 – rule
-Presence of more than 20 microaneurysms in the four quadrants
-or venous beading in two quadrants and/or one quadrant with IRMA

Therapeutic strategies in macular edema:

Currently, the treatment of a macular edema is a most discussed topic. A proposal for control and treatment in diabetic macular edema is presented in this video.

A proposal for control and treatment:
In severe diabetic retinopathy a fluorescence angiography (FA) and OCT are performed. These two methods are the basis for the indication of a therapy. The laser is still an important tool, especially for the treatment of ischemia. After treatment, frequent monitoring is necessary.

Consider the morphology and function of the macula:
In a dry macula, good visual acuity and inconspicuous biomicroscopy, checks are carried out every year.
In borderline cases an OCT or fluorescence angiography (FA) should be performed, followed by an appropriate therapy.
In a clinically significant macular edeme, OCT and/or fluorescence angiography (FA) are the basis, followed by Laser and/or anti VEGF therapy. After treatment, a frequent monitoring is necessary in every case.

In cases with a thickened foveola a proposal may be:

If the edema is not located quite centrally, a focal laser may be sufficient. When this laser is not successful, we go back again in the proposed scheme.
If the foveola is thickened centrally, the anti-VEGF therapy is then possible.
If no stabilization occurs, the vision rises an additional laser treatment may be useful.
If therapy stabilized the situation, ​​a break and a close monitoring follows. If everything remains stable, the patient remains in the small control loop.
If the situation worsens, the patient returns to the top level of control.

This is not a fixed regimen, but must be customized and changed over time.

Complication in diabetes facial nerve palsy

Wednesday, June 13th, 2012

(Bells palsy, Fazialisparese)  suddenly a “lopsided” face:

The facial nerve palsy (Bells palsy) is one of the most common injuries of affected cranial nerves. The paralysis affects all of its innervated facial muscles, so that the origin of the disorder is quickly visible. Most often there is no clear cause, it is often associated with infection.

In diabetes a facial paralysis occurs more often, which fortunately is usually benign in course with spontaneous remission.
A major problem is due to paralysis of outer eye muscles resulting in an incomplete eyelid closing. The cornea can dry out, a visual loss occurs, even infection and scarring can permanently impair vision.
Therefore, a good humidification is important using eye drops, ointments and a monoculus (Uhrglasverband).

Problems of monoculus
The disadvantage of a monoculus is that older people show difficulties to change the monoculus themselves, withdrawal may be painful in a thin and sensitive skin,  allergies to adhesives occur soon, massive cosmetic restriction with grotesque appearance  interfere with the patient in his dealings with his social environment. Thus the patient may not feel very comfortable. GETOCT shows a nice trick to improve patient’s quality of life. Plese view the video:

film photo award 2010: win up to 5000 Swiss Francs!

Thursday, June 3rd, 2010

getoct® and its partners seek the best film&photo work about the human eye of 2010!
Submitted photos and movies will represent the eye as a central organ that allows vision in all its facets.

We want to promote the discussion of photography, film and a professional networking in the area of human eye diseases, vision and health care from many different perspectives, especially from the view of OCT (optical coherence tomography) if possible. We want to go public and look for an annual recurring reference point in the daily flood of images and films.

In the first year of the founding the getoct®film&photo award is worth praise in the amount of 5’000 .- Swiss Francs and more. Work will be submitted in the four categories. Entry forms, regulations and information to the jury: or

We are excited for your contributions! See you and have fun!
