Questions before the purchase

The OkuStim device uses a weak electrical current to stimulate the eyes. This happens via the OkuEl electrodes, which are held on the surface of the eye with the help of the OkuSpex frame. The stimulation takes place with closed eyes. The therapy parameters are determined and set by the doctor beforehand.

The therapy with OkuStim offers the chance to slow down the course of the disease. This can present itself in:

  • Slowing down the progression of visual field loss
  • Improvement of the cellular activity. Cellular activity is measured by means of an electroretinogram (ERG). An increased cellular activity means, among other things, an enhanced reaction of the cells to light stimuli. This can meanthat a greater number of cells is involved in the visual impression, which in turn can have a positive effect on the visual field.
  • Improvement of visual acuity

As with all therapies and medicines, different patients may benefit differently from the TES therapy with the OkuStim system.

The therapy is applied once a week for 30 minutes. This therapy aims to slow down the progression of the disease, therefore it is a permanent therapy. The duration depends on its apparent benefit.

 

Research has shown that electrical stimulation with weak currents can activate signaling pathways the in affected retina that have a protective effect on retinal cells. This neuroprotective effect can delay retinal degeneration and preserve the function of the remaining cells.

 

The aim of the therapy is to maintain cellular activity. This is only possible if the visual cells still have a residual function. Therefore, one should commence the therapy as early as possible after the onset of retinitis pigmentosa. The therapy is out of the question, however, if growth processes are active in the eye (such as macular edema). Please contact one of the competence centres for a personal examination and consultation.

 

Data and results are only available for retinitis pigmentosa.
Treatment of other hereditary retinal dystrophies such as cone rod dystrophy, choroideremia or Usher syndrome is possible.
Future studies will be required to evaluate the effectiveness of the OkuStim System in other eye diseases such as AMD and Stargardt's disease.

 

In studies the therapy has only been used with adult patients. There is no data available for underage patients.

 

The costs for the therapy and the OkuStim products have to be borne by the patient. However, reimbursement by the health insurance can be requested on an individual case basis. This may vary by country.

Questions about the application

The OkuStim system uses a weak electrical current to stimulate the eyes. For this purpose, the OkuEl® electrodes are placed on the surface of the eye with the OkuSpex frame.

To ensure optimal stimulation, the thin electrode thread has to be in contact with the surface of the eye over a length of at least 1 cm. The contact is controlled by measuring the electrical resistance. This is automatically measured by the OkuStim during the entire stimulation period and is shown on the display for both eyes (OS=left, OD=right).

Usually the resistance is between 4,000 ohms and 6,000 ohms, lower and higher values are fine. The resistance varies from user to user and changes during stimulation. If the resistance is too high (above 15,000 ohms) the OkuStim will indicate this automatically with an acoustic signal.

The stimulation is safe as long as the system is used correctly. This has now been proven in five clinical studies.
It is important that the application is carried out according to the instructions in the user manual.
The correct application is trained in an individual instruction session.
