Fundus flavimaculatus and Stargardt's disease
American Journal of Ophthalmology
|October 1, 1976
Summary
Fundus flavimaculatus and Stargardt disease often cause vision loss due to macular atrophy. These conditions typically follow an autosomal-recessive inheritance pattern, with characteristic flecks on eye examination.
Area of Science:
- Ophthalmology
- Medical Genetics
Background:
- Fundus flavimaculatus and Stargardt disease are inherited retinal disorders.
- Both conditions are characterized by macular atrophy and yellowish-white flecks in the fundus.
Purpose of the Study:
- To characterize the clinical features and inheritance patterns of fundus flavimaculatus and Stargardt disease.
- To correlate fundus findings with visual acuity and electrophysiological tests.
Main Methods:
- Retrospective analysis of 42 patients with fundus flavimaculatus and Stargardt disease.
- Clinical examination, fundus photography, fluorescein angiography, and electroretinography (ERG) / electro-oculography (EOG).
Main Results:
- Most patients (42) had reduced visual acuity due to macular atrophy.
- Autosomal-recessive inheritance was consistent with family histories.
- Yellow-white flecks varied in appearance over time and were often nonfluorescent on angiography.
- ERG/EOG were normal in posterior pole-limited disease but abnormal in widespread lesions.
Conclusions:
- Fundus flavimaculatus and Stargardt disease share clinical and angiographic features.
- Disease progression involves retinal pigment epithelial atrophy and nonfluorescence.
- Electrophysiological test results correlate with the extent of retinal involvement.
