Colposcopes: a critical review.

A multidimensional professional team consisting of a practicing colposcopist, a mechanical engineer, and a medical photographer independently critically evaluated the features of selected colposcopes. Qualitative observations and quantitative measurements were performed on 13 colposcopes representing eight manufacturers and distributors. Optical characteristics, ocular system operation, mobility and stability, relative ease of use, component characteristics, space for instrumentation, and visual illumination, uniformity, and color were comparatively assessed. The specific colposcope information provided may benefit practicing physicians or novice colposcopists who are contemplating purchasing a colposcope. The presented framework of critical feature evaluation may also facilitate the informed selection of other colposcopes not included in this selective, critical, comprehensive review.

Colpophotography systems: a review.

Colpophotography and video colposcopy systems are useful for pathology documentation purposes, patient education, and colposcopy training. A wide variety of colposcopic visual media components are available to enhance routine colposcopy. Colpophotographic systems supplied by eight colposcope manufacturers were critically evaluated by a colposcopist and a medical photographer. Components were independently and objectively analyzed. Photographic examination considered color, illumination uniformity, and coverage of illumination at all possible colposcopic magnifications. Photographs were developed by a standardized technique. The investigation results clearly demonstrated variability between different colpophotographic systems. Quality colpophotography is dependent on certain colposcope features and potential modifications. Colpophotography and video colposcopy systems complement the standard colposcopic procedure.
