“…24 When these diagnoses were compared with those of an otologist, their accuracy was even slightly less and reached 50% in children aged less than 10 years. 28 The main purpose of developing the spectrophotometric otoscope is to provide the primary-care physician with an efficient new tool that can raise the accuracy of diagnosis of ear disease closer to that of a trained otologist with an otomicroscope.…”

“…More accurate diagnosis could reduce unnecessary prescribing of antibiotics, and would thereby help in fighting the major problem of selection and spread of multi-drug-resistant bacterial pathogens-a problem that arises from extensive use of antimicrobial agents for otitis media. 5,25,28,33 As a side benefit, it could help to reduce the cost of treatment of otitis media, which amounts to more than $5 billion annually in the USA alone. [33][34][35] We believe that the new system that we have developed could eventually become a basic diagnostic tool for primary-care physicians and medical auxiliaries.…”

Otitis media is one of the most common childhood ailments and, therefore, has a significant impact on public healthcare expenditure. The initial diagnosis is usually performed by a primary-care physician and is based upon otoscopy and symptomatology; the certainty of diagnosis of acute otitis media is only 58-73%. This study aimed to assess the efficacy of a spectrophotometer-based system in identifying otitis media by comparing the output from the system with the clinical diagnosis of an experienced otologist and, hence, to evaluate the system as a diagnostic aid to primary-care physicians. The study was prospective and double blind. An otologist examined 258 patients consecutively with an oto-microscope and all of the patients were simultaneously examined with a spectrometer-based data acquisition system incorporated in a standard otoscope. The otologist's diagnosis served as a "gold standard". The acquired data were analysed by means of partial least squares regression. The system correctly differentiated acute otitis media from serous otitis media and normal ears with sensitivity of 93% and specificity of 88%. The sensitivity and specificity were 89 and 95%, respectively, in a subset of subjects aged 12 y or less. Spectrophotometry was found to be a highly accurate means of diagnosing acute otitis media. We consider that it will become an important diagnostic aid for primary care physicians.

“…Since evaluation of the tympanic membrane is based on subjective impression of its color, position, and movement, often under suboptimal circumstances, some interobserver variability and diagnostic uncertainty inevitably occur [35][36][37]. In Texas, with an expert panel, tympanometry, and tympanocentesis findings being the gold standard, pediatricians and otolaryngologists evaluated videotapes of pneumatic otoscopic examinations.…”

“…Several studies propose that the position of the tympanic membrane is an important characteristic when distinguishing between AOM, OME and healthy conditions (PICHICHERO, 2000;RUUSKANEN and HEIKKINEN, 1994;HEMLIN et al, 1998;SCHWARTZ et al, 1981). However, this parameter does not, by itself, reach a satisfactory level in sensitivity or specificity.…”

A contact-free sensor consisting of two parallel optical-fibre arrays was designed to assess surface shapes of diffusely scattering media. By sequentially illuminating objects using one fibre array and detecting the diffusely back-scattered photons by the other, a source-detector intensity matrix was formed, where the matrix element (i, j) was the intensity at detector j when light source i was excited. Experimental data from convex and concave polyacetal plastic surfaces were recorded. A mathematical model was used for simulating source-detector intensity matrices for the surfaces analysed in the experiments. Experimental results from the system were compared with the theoretically expected results provided by the mathematical model. The shape and relative amplitude showed similar behaviour in the experiments and simulations. A convex/concave discriminator index D, representing the detected intensity difference between two source-detector separations, was defined. The relative dynamic range of D, defined as the difference between the maximum and the minimum divided by the mean of the index, was 1.37 for convex surfaces and 0.68 for concave surfaces, at a measuring distance of 4.5 mm. The index D was positive for convex surfaces and negative for concave surfaces, which showed that the system could distinguish between convex and concave surfaces, an important result for the diagnosis of otitis media.
