OBJECTIVE To propose a method of diagnosis of mild papilloedema (PO) using peripapillary total retinal (PTR) thickness measurement by spectral domain optical coherence tomography (OCT). METHODS 24 eyes in 24 patients with PO caused by increased intracranial pressure and 22 eyes in 22 normal subjects were studied. OCT high-quality fundus images were analysed and graded by three masked observer...

Measurement of subcutaneous fat thickness with a skinfold caliper is a simple and inexpensive technique for assessment of body composition, but is influenced by the skin site or the obesity level. The resulting measurement errors may influence the prediction accuracy of body density. We therefore aimed to clarify the characteristics of measurement errors with a skinfold caliper and to determine...

Real-time measurement of plastic film thickness during production is extremely important to guarantee planarity the final film. Standard techniques are based on capacitive measurements, in close contact with These require continuous calibration and temperature compensation, while their can damage Different optical contactless described literature, but none has found application real production,...
