Table 2 Parameters used for automatic quantification of SNP structures

From: Changes in the micromorphology of the corneal subbasal nerve plexus in patients after plaque brachytherapy

Component pixels

number of pixels identified as nerve fibres

Nerve fibre components

number of separate nerve fibre networks

Skeleton pixels

number of pixels representing the medial axes of nerve fibres

Single nerve fibres

number of all nerve segments between nerve branches and nerve ends

Total nerve fibre length/average single nerve fibre length

length of all nerve fibres in the image area/average length of single nerve fibres

Nerve fibre density

length of all fibres in respect to 1 mm2

Number of connectivity points

number of nerve fibres entering or leaving the image area to the outside
