Three-dimensional optical coherence tomography of granular corneal dystrophy.
OBJECTIVE
To describe 3-dimensional optical coherence tomography (OCT) findings in a case of granular corneal dystrophy.


METHODS
A 1310-nm high-speed swept-source OCT prototype was used to image the 3-dimensional structures of the cornea of a patient with granular corneal dystrophy.


RESULTS
Three-dimensional OCT clearly showed multiple highly reflective lesions, corresponding to the deposits in the cornea. Volume of the deposits within the central 1.5 mm of the cornea was 0.11 mm and occupied 2.98% of the corneal volume.


CONCLUSIONS
Three-dimensional OCT allows objective and noninvasive assessment of granular corneal dystrophy.
