Stargardt Disease and its Treatment

What is Stargardt disease?

Stargardt disease is an inherited retinal condition that mainly affects the macula, the area needed for detailed central vision. It is most often associated with changes in the ABCA4 gene. Symptoms may begin in childhood or adulthood.

Pathophysiology

Stargardt's disease is the most common form of juvenile-onset macular dystrophy. As mentioned before, it is caused by mutations in the ABCA4 gene, resulting in errors in the processing and transport of all-trans retinal in the photoreceptor visual cycle, leading to the formation of N- retinylidene-N-retinyl-ethanolamine (A2E) and the accumulation of lipofuscin in the photoreceptor outer segments and RPE layer.

The accumulation of lipofuscin is a key factor in causing the progressive bilateral central vision loss associated with Stargardt's disease. The disease is typically characterized by the presence of a "beaten bronze" or bull's eye appearance of the macula and subretinal lipofuscin spots.

Lipofuscin accumulation is influenced by various factors, including a deficiency in the conversion of all-trans retinol to 11-cis-retinal in RPE cells, as well as the phagocytosis of photoreceptor outer segments by RPE cells. The resulting formation of A2E can react with oxygen, leading to its conversion into A2E-epoxides upon exposure to light. A2E increases the sensitivity of RPE cells to blue light and can cause various toxic effects, including destabilization of mitochondrial and lysosomal membranes. Additionally, A2E can inhibit cytochrome c oxidase and disrupt electron flow in the respiratory chain, leading to energy metabolism deficiencies and the production of reactive oxygen species.

It has been shown that A2E accumulation and its toxic effects are light- dependent. However, destabilization of lysosomal and mitochondrial membranes can occur even in the absence of light. Studies have demonstrated that A2E can destabilize isolated mitochondria and lysosomes, indicating its ability to induce destabilization regardless of light exposure.
Alternatively, a study has proposed an alternative toxic pathway in RPE cells loaded with A2E. In this study, lysosomal destabilization was not observed, but the cells were unable to fully digest the phagocytosed photoreceptor outer segments within 24 hours. The accumulation of undigested phospholipids, which are a source of reactive oxygen species, was found to be a result of the circadian-regulated process of phagocytosis.

Symptoms of Stargardt disease

People may notice blurred central vision or blind spots, sensitivity to light, changes in colour vision and difficulty adapting between light and dark. The pattern and progression vary.

Symptoms alone do not establish a diagnosis; an eye specialist can assess their cause.

Diagnosis and ongoing care

An eye specialist may use a dilated examination, retinal imaging, retinal function tests and genetic testing to assess Stargardt disease.

Low-vision aids and rehabilitation can help with everyday activities. Research into disease-targeted treatments continues. Discuss available care and research options with a retinal specialist.

Treatment of Stargardt Disease with Electro-Acupuncture Method of Dr.Osman FIRATLI in Firatli Clinic

We offer Electro-Acupuncture treatment for patients with Stargardt Disease . Our treatment has shown its effectiveness of regaining the photoreceptors functions with more than 1000 patients with Stargardt Disease ; more than 5000 patients Retinitis Pigmentosa and Stargardt Patients.

The treatment and its success has been presented in several World-Congresses since 2007 with the medical evidences of our own patients; comparing their own visual field tests just before the treatment and after the treatment to indicate the improvement on both peripheral and central vision.

On this web-site you can view some videos of their own; presenting their own vision field test compare and how they benefited from our treatment.

Success Rate

In conventional medicine researches continue with the aim of preventing the disease from advancing further. That will even be considered as a huge success.

The aim of our treatment is not only preventing further deterioration of the eyesight but also improving the visual acuity and peripheral vision of our patients. With this purpose, our patients perform several medical tests at the eye hospitals before the therapy. These medical tests are repeated after the treatment to show the improvements that our patients also realize during their treatment period.

Considering that we only think our treatment is successful when the examinations at our clinic and the medical tests performed before and after clearly show the improvements on the eyesight and visual acuity.

Success rate of the therapy with Dr.Firatli Method is more than 90%
The combinations used during the therapy , applied treatment method and the electro-stimulation combinations depending on the type of the patient are unique and important factors on the high success rate.

Stargardt disease: preparing for an informed consultation

Patients and families often have questions about central vision, daily activities and the difference between care options and treatment research. Use the information below to prepare for a discussion about your own circumstances.

What does the diagnosis mean?

Stargardt disease mainly affects the macula, which is important for detailed central vision. It is most often linked to changes in the ABCA4 gene. Your eye specialist can explain the findings in your examinations and whether genetic testing may help clarify the diagnosis.

What can support everyday life?

Low-vision aids and rehabilitation can help people use their remaining vision for daily tasks. Tell your eye-care team which activities are difficult, such as reading, recognising faces or adjusting to changing light.

How should I approach treatment information?

Ask whether a proposed option is established care, a research intervention or a clinic-specific approach. Request information about evidence, limitations, possible risks and follow-up. A personal experience does not predict the outcome for another patient.

Where can I find clinic information?

Explore the patient video collection, the clinic and team and the consultation enquiry process. If you are travelling from abroad, discuss the assessment and practical arrangements before booking your journey.
