Electro-oculogram testing in fundus flavimaculatus.

Electro-oculogram (EOG) measurements were obtained on seven patients with moderately extensive lesions of fundus flavimaculatus. Each patient was tested by two different methods of measuring EOG light-peak to dark-trough ratios. The results show that erroneously low ratios can be observed unless a diffusing sphere is employed in the determination of light-peak to dark-trough ratios in fundus flavimaculatus and presumably other diseases that affect primarily the posterior pole.

Dark adaptation testing in heterozygotes of Usher's syndrome.

Fourteen heterozygous carriers of Usher's syndrome were evaluated by ophthalmoscopy and dark adaptation testing. The normal findings in our study are discussed and compared with those of previous reports, which suggested that abnormal dark adaptation thresholds and fundus abnormalities may be seen in heterozygotes.
