Summary
Bilateral ring scotoma, an eye condition, can be an early sign of adult-onset Stargardt disease. This visual field defect, typically seen in macular degeneration or drug toxicity, highlights macula involvement.
Area of Science:
- Ophthalmology
- Medical Genetics
- Visual Neuroscience
Background:
- Ring scotoma is an annular visual field defect.
- Common causes include age-related macular degeneration and hydroxychloroquine toxicity.
- These conditions typically affect the macula.
Purpose of the Study:
- To report bilateral ring scotoma as an initial presentation of adult-onset Stargardt disease.
- To emphasize the diagnostic value of ring scotoma in localizing macular lesions.
Main Methods:
- Case report describing patients with adult-onset Stargardt disease.
- Clinical examination and visual field testing were performed.
- Diagnostic imaging of the macula was utilized.
Main Results:
- Bilateral ring scotoma was the presenting visual field defect.
- The findings were consistent with adult-onset Stargardt disease.
- The ring scotoma precisely localized the macular pathology.
Conclusions:
- Adult-onset Stargardt disease can manifest with bilateral ring scotoma.
- Ring scotoma is a significant indicator of macular disease.
- Early identification of ring scotoma aids in diagnosing Stargardt disease.
