A fully automated tortuosity quantification system with application to corneal nerve fibres in confocal microscopy images
Recent clinical research has highlighted important links between a number of diseases and the tortuosity of curvilinear anatomical structures like corneal nerve fibres, suggesting that tortuosity changes might detect early stages of specific conditions. Currently, clinical studies are mainly based on subjective, visual assessment, with limited repeatability and inter-observer agreement. To addr...
متن کاملAcquired medullated nerve fibres.
Myelination of nerve fibres normally stops at the lamina cribrosa. When it does proceed beyond the lamina cribrosa, it is believed to do so shortly after birth. A patient is recorded in whom medullated nerve fibres developed in the retina during adult life.
متن کاملConduction in Nerve Fibres
Data by E. A. Blair and Erlanger on the voltage-capacity curves and the nerve impulse velocities of each of several fibres in the same nerve trunk are related to Rashevsky's equation for the velocity of transmission in nerve. The results lend support to Rashevsky's analysis. Other empirical relations between the velocity and the parameters of the excitation equations indicate the correctness of...
متن کاملDual-Model Automatic Detection of Nerve-Fibres in Corneal Confocal Microscopy Images
Corneal Confocal Microscopy (CCM) imaging is a non-invasive surrogate of detecting, quantifying and monitoring diabetic peripheral neuropathy. This paper presents an automated method for detecting nerve-fibres from CCM images using a dual-model detection algorithm and compares the performance to well-established texture and feature detection methods. The algorithm comprises two separate models,...
متن کاملTapering of human nerve fibres.
To determine the tapering of human nerve fibres, rostral and caudal root pieces of cauda equina nerve roots were removed and nerve fibre diameter distributions were constructed for 4 myelin sheath thickness ranges for the two sites, and compared with each other. The reduction of the group diameter in the different alpha-motoneuron groups was 0.2 % per 13 cm. Accounting for systematic errors, th...
