Stargardt's disease treatment: what is known, and what helps today
Stargardt's disease is the most common inherited macular dystrophy, and it mainly affects central vision, usually from childhood or the teenage years. This page explains how it is confirmed, what you can do now, and which treatments are being researched.
Understanding Stargardt's disease
Stargardt's disease is an inherited eye condition in which the macula, the central part of the retina used for reading, recognising faces and seeing detail, gradually loses function. In most people it is caused by changes in the ABCA4 gene, which leads to a build-up of waste material in the retina's supporting cells and, over time, damage to the light-sensing cells above them.
It is different from retinitis pigmentosa. Retinitis pigmentosa usually begins with night blindness and shrinking side vision, while Stargardt's disease usually begins with blurred or patchy central vision and often leaves side vision intact. Knowing which condition you have decides what advice applies.
Signs and course of Stargardt's disease
The pattern differs between people, even within one family.
- Blurred or smudged central visionOften the first sign, and not corrected by glasses.
- Difficulty with reading and fine detailSchool, screens and close work become harder as the macula is affected.
- Slow adjustment to dim lightSome people notice it, though it is usually less marked than in retinitis pigmentosa.
- Colour and glare problemsColours can look washed out and bright light can be uncomfortable.
- Variable speed of changeOnset in childhood often progresses faster, while adult-onset Stargardt's disease is usually milder.
How Stargardt's disease is diagnosed
A retina specialist usually combines several tests.
- Dilated fundus examinationLooks for the yellow-white flecks and macular changes typical of the condition.
- Fundus autofluorescenceShows areas of retinal damage and is one of the most useful tests for tracking change.
- OCT imagingMeasures thinning of the macula and the health of its layers.
- Electroretinography (ERG)Checks how the wider retina is working and helps separate Stargardt's disease from similar conditions.
- Genetic testingLooks for ABCA4 and other gene changes, confirms the diagnosis and supports family counselling.
What helps today
No treatment for Stargardt's disease has been approved yet, but these steps are widely recommended.
Protect the retina from light
Quality sunglasses and a brimmed hat are commonly advised for outdoor use. This is a precaution, not a proven way to stop progression.
Avoid vitamin A supplements
Unlike in some forms of retinitis pigmentosa, high-dose vitamin A is generally not recommended in Stargardt's disease. Check with your retina specialist before taking any supplement.
Low-vision rehabilitation
Magnifiers, electronic reading aids and training make school, work and daily tasks easier.
Treat complications
Rarely, abnormal vessels grow under the macula and can be treated. Report sudden distortion to your specialist straight away.
Treatments being researched
Several approaches are in clinical trials, and none is approved yet.
Gene therapy
Approaches to deliver a working ABCA4 gene are in early trials, with size of the gene one of the main technical challenges.
Oral medicines
Drugs designed to reduce the build-up of toxic vitamin A by-products in the retina are being tested in later-phase trials.
Cell transplantation
Replacing damaged retinal pigment epithelium cells is under early-phase study, and is covered on our stem cell pages.
Registered trials
Your retina specialist can check whether any study fits your gene change and stage.
Living with Stargardt's disease: practical support
Good support protects independence and education.
Low-vision aids
Magnifiers, large-print material, high-contrast settings and screen readers.
School and workplace adjustments
Accessible materials, extra time and seating can make a real difference.
Genetic counselling
Explains inheritance, usually recessive, and risk for family members.
Regular monitoring
Tracks change over time and keeps you informed about new trials.

Get ConsultationFrequently asked questions
Is there a cure for Stargardt's disease?
Not yet. No treatment is approved to cure or stop Stargardt's disease. Care focuses on protecting the retina, supporting vision and following legitimate research.
Will I go completely blind with Stargardt's disease?
Stargardt's disease mainly affects central vision. Most people keep their side vision, so total blindness is not typical, although central vision loss can be significant.
Is Stargardt's disease the same as retinitis pigmentosa?
No. They are both inherited retinal diseases, but Stargardt's affects the macula and central vision first, while retinitis pigmentosa affects night and side vision first.
Can diet or supplements slow Stargardt's disease?
Evidence is limited. High-dose vitamin A is generally not advised, so speak to your retina specialist before taking supplements.
