Choroidal thinning and "stair-case" foveal sign in a patient with Alport syndrome.

PURPOSE: To quantitatively describe choroidal thickness in a patient with Alport syndrome and to qualitatively describe an unusual "stair-case" foveal sign.

METHODS

Retrospective case report.

RESULTS

This is the first case, to our knowledge, of the stair-case foveal sign. This is also the first case where choroidal thickness in a patient with Alport rsyndrome has been quantitatively described using enhanced depth imaging optical coherence tomography.

CONCLUSION

Stair-case foveal sign and choroidal thinning are two new signs that clinicians can expect to encounter on optical coherence tomography imaging of patients with Alport syndrome.
