Clinical and specular micrographic findings in corneal guttata and Fuchs' corneal endothelial dystrophy

Focal excrescenses of altered basement membrane material, known as corneal guttata, are a common occurrence in the elderly. A small proportion of those who develop this condition exhibit signs of corneal endothelial dysfunction and progress to Fuchs' corneal endothelial dystrophy. The relationship between the distribution and relative density of guttata and the morphological appearance of the corneal endothelium is as yet poorly understood.
