Patients and Methods: A link to a 9-question survey was electronically distributed to a national sample of 6000 pediatricians through Medical Marketing Services Inc. Data were collected using Survey Monkey. Results: Email open rate was 11%;37% of those who opened the email responded (225 respondents). Over ninety percent of respondents perform some type of vision screening at least yearly, although age at which screening began varied, with two thirds of respondents instituting formal vision screening after three years. Fifty eight percent of respondents were either extremely unsatisfied, unsatisfied or only somewhat satisfied with their current screening method. Preferred methods of screening and confidence of pediatricians in their ability to detect pathology varied for children under versus over age three. The least frequently used methods for all age groups were autorefraction and photoscreening. The most commonly reported barriers to screening were inadequate training (48%), time required for exam (42%), and inadequate reimbursement (32%). Conclusions: Perceived barriers to vision screening in the pediatrician office have been previously identified, and photoscreening and autorefraction have been identified as a possible means to circumvent them. In spite of the addition of new procedural codes, pediatricians continue to report similar barriers to screening.展开更多

Methods: Cross-sectional study of 148 children who received photoscreenings via PPS and IPS and a comprehensive pediatric ophthalmic examination in our office. Patients were considered to have amblyogenic risk factors based on the AAPOS referral criteria guidelines. Results: 45 percent of patients undergoing a pediatric ophthalmology examination were found to have amblyopia or amblyogenic risk factors. In this study, PPS demonstrated an overall sensitivity of 75.4%, specificity of 68.0%, positive predictive value (PPV) of 67.1%, and negative predictive value (NPV) of 76.1%. However, IPS photoscreener had an overall sensitivity of 66.2%, specificity of 87.6%, PPV of 81.8%, and NPV of 75.5%. Discussion: The accuracy of PPS and IPS was compared in different age groups. The sensitivity and specificity were analyzed according to varied amblyogenic risk factors. The statistic results of this study were compared to those of previous studies, including Vision in Preschoolers (VIP) Study and the Iowa PhotoScreening Program. Conclusion: PPS and IPS proved to be useful tools in the objective vision screening in children. PPS was found to have a higher sensitivity, and IPS showed a higher specificity and PPV in detecting amblyopic risk factors. In conclusion, one device may be more beneficial over the other, depending on the patient population and office settings.展开更多
