“…In the finding related by Sargent et al (11), after conversion into grayscale and alignment of the Case Report/Clinical Techniques digitized images, they were subtracted by using the "subtract" command of the "calculation" tool. In the present study, the same procedure was performed maintaining a standardized radiographic technique because this software is not specific for digital subtraction and has no specific tools to correct any variation of image alignment.…”

“…For example, Ikeda and coworkers (1997) have used Photoshop not only to scan selected fields from microscope slides but also to compose seamless widefield images of large tissue sections. Others have used Photoshop to superimpose grids over scanned images (Gatlin et al 1993) or to assess facial movement as a means of grading facial nerve in-jury (Sargent et al 1998). However, none of these studies has actually made use of the tools for recognition and quantification described here.…”

SUMMARYSimultaneous detection of two different antigens on paraffin-embedded and frozen tissues can be accomplished by double immunohistochemistry. However, many double chromogen systems suffer from signal overlap, precluding definite signal quantification. To separate and quantitatively analyze the different chromogens, we imported images into a Macintosh computer using a CCD camera attached to a diagnostic microscope and used Photoshop software for the recognition, selection, and separation of colors. We show here that Photoshop-based image analysis allows complete separation of chromogens not only on the basis of their RGB spectral characteristics, but also on the basis of information concerning saturation, hue, and luminosity intrinsic to the digitized images. We demonstrate that Photoshop-based image analysis provides superior results compared to color separation using bandpass filters. Quantification of the individual chromogens is then provided by Photoshop using the Histogram command, which supplies information on the luminosity (corresponding to gray levels of black-and-white images) and on the number of pixels as a measure of spatial distribution.

The ophthalmologist plays a pivotal role in the evaluation and rehabilitation of patients with facial nerve palsy. It is crucial to recognize and treat the potentially life-threatening underlying causes. The immediate ophthalmic priority is to ensure adequate corneal protection. The medium to long-term management consists of treatment of epiphora, hyperkinetic disorders secondary to aberrant regeneration and poor cosmesis. Patients should be appropriately referred for general facial re-animation. This review aims to provide a guide to the management of this complex condition.

Measurement of Facial Movement With Computer Software

Abstract: The desktop computer software can be used to calculate the Nottingham score. Digital subtraction as a measure of facial function warrants further study.
