OBJECTIVE To analyze the onset and extent of the dermatological changes associated with microdermabrasion. METHODS Eleven volunteers, aged 31-62 years old, underwent a series of six aluminum oxide microdermabrasion facial treatments spaced over 7 to 10-day intervals. White light photography and digital ultraviolet fluorescent photography and skin biopsies were obtained prior to the study, aft...

Computational photography combines plentiful computing, digital sensors, modern optics, actuators, and smart lights to escape the limitations of traditional cameras, enables novel imaging applications and simplifies many computer vision tasks. However, a majority of current Computational photography methods involves taking multiple sequential photos by changing scene parameters and fusing the p...

Purpose: To investigate the clinical significance of ocular torsion in children by analyzing associated ophthalmic diseases.Methods: Fundus images were used to detect one or both eyes 83 aged 2-12 years at a pediatric ophthalmology clinic. In cases with torsion, diseases, including strabismus, amblyopia, and refractive errors, investigated.Results: Among patients, 59 (71.2%) 45 (54.2%) had stra...

Expanded polyethylene foam (Plastazote) is used in the treatment of rheumatoid, diabetic, and leprotic foot disorders. This paper describes a diagnostic use for this material. Two photographic techniques combine to give vivid and quantitative representations of foot deformities which are easily applicable to clinical use. Relief photography uses illumination to create an illusion of solidity in...

OBJECTIVE To compare the diagnostic properties of a nonmydriatic 200° ultra-widefield scanning laser ophthalmoscope (SLO) versus mydriatic Early Treatment of Diabetic Retinopathy Study (ETDRS) 7-field photography for diabetic retinopathy (DR) screening. RESEARCH DESIGN AND METHODS A consecutive series of 212 eyes of 141 patients with different levels of DR were examined. Grading of DR and cli...

Digital photography is a relatively new topic for scholarly study in the area of computer mediated communication. Photographic technologies were only first computerized in the 1990s, but have rapidly supplanted older film technologies for a majority of professional uses. Digital photography has not simply substituted silicon chips for film, however, but has brought about rapid changes throughou...

OBJECTIVE We developed a Web-based, blinded, prospective, randomized, multicenter trial, using standardized digital photography to clinically evaluate hand burn depth and accurately determine wound area with digital planimetry. METHODS Photos in each center were taken with identical digital cameras with standardized settings on a custom backdrop developed at Wake Forest University containing ...

Human beings have never encountered as many photographs we do today. They surround us in public spaces, and populate the numerous screens access our daily lives. Anthropologists are working to understand social cultural ramifications of this ubiquitous photography on societies throughout globe. This entry examines work anthropologists done on, with, photography. It surveys conclusions reached a...
