title: Retinal depression sign indicating a small retinal infarct.
abstract: Retinal depression, a newly observed sign, has been observed as an abnormality in the reflection from the internal limiting lamina produced by depression of the inner surface of the retina after a small retinal infarct. These depressions were first observed in 16 patients with sickling hemoglobinopathies. Additionally, I examined a patient with systemic hypertension, a patient with retinal arteriolitis, and a patient with juvenile onset diabetes mellitus who also had retinal depression.
