Visual improvement with low vision aids in Stargardt's disease

Area of Science:

• Ophthalmology
• Low Vision Research
• Genetics

Background:

• Stargardt disease, also known as fundus flavimaculatus, is a common inherited macular dystrophy.
• It leads to progressive vision loss, significantly impacting patients' quality of life.

Purpose of the Study:

• To assess the efficacy of low vision aids in improving visual acuity for individuals with Stargardt disease or fundus flavimaculatus.
• To quantify the visual gains achieved with specific low vision devices.

Main Methods:

• A cohort of 71 patients diagnosed with Stargardt disease or fundus flavimaculatus was enrolled.
• Visual acuity was measured with and without the use of a telescopic low vision aid.
• Reading acuity was assessed using standard 4.0 point print.

Main Results:

• The median visual acuity improved from 10/77 without an aid to 10/32 with a telescopic system.
• Best corrected reading acuity of 4.0 point print was achieved by 54 patients.
• All participants demonstrated improved visual acuity for both distance and reading tasks when using low vision aids.

Conclusions:

• Low vision aids are effective in enhancing visual function for patients with Stargardt disease or fundus flavimaculatus.
• Telescopic systems and other aids can significantly improve distance and reading acuity.
• These findings support the integration of low vision aids into the management of Stargardt disease.
