“…13 We believe our service is the first to completely incorporate electronic referral with digital images into a regional ophthalmic service with long-term service delivery results. Improving two-way communication through novel use of currently available secure IT technology between hospital and community practice, dramatically reduced steps in the referral pathway with shorter waiting times.…”

Purpose Demands on publicly funded ophthalmic services worldwide continue to increase with new treatments, waiting time targets, working time limits, and restricted budgets. These highlight the necessity to develop innovative ways of utilising existing capacity more effectively. Method A new regional, fully electronic ophthalmic-referral service with digital imaging was trialled using existing information-technology (IT) infrastructure.

Subsequently, these images were stored as a JPEG (Joint Photographers Experts Group; http:==jpeg.org) file, transmitted via data-cable to a PC and integrated into a teleconsultation web application: www.dermahandy.net (Chao, 2003). Afterwards the patient was examined by the specialist in the outpatient service while the images were diagnosed independently by two teledermatologist.…”

Mobile telemedicine is becoming more and more important in the 21st century. As a visual profession dermatology provides perfect conditions for using telemedicine tools in general and mobile devices in particular. Teledermatology advances the reliability of diagnosis by expert consultations without expensive and time-consuming relocations. Consecutively, the quality of patient's care will be raised and the costs of the health care system can be reduced.Die Geburt der mobilen Teledermatologie.Die mobile Telemedizin erlangt im 21. Jahrhundert zunehmend grö ßere Bedeutung. Die Dermatologie als visuelles Fach eignet sich paradigmatisch, die vielfä ltigen Mö glichkeiten der Telemedizin im Allgemeinen und der mobilen Endgerä te im Speziellen zu nutzen. Die Teledermatologie verbessert die Diagnosesicherheit durch die Mö glichkeit von Expertenkonsultationen ohne kostspielige und zeitraubende Standortwechsel. Dies fü hrt zu einer Verbesserung in der Qualitä t der Patientenversorgung sowie zu Kosteneinsparungen im Gesundheitssystem.

“…Telemedicine is also a powerful tool for alleviating the lack of doctors in resource-poor areas. Furthermore, it is a viable option for almost all medical specialties, particularly those for which images comprise the main diagnostic tool (4)(5)(6)(7) . Thus, the fields of radiology, dermatology, pathology, ultrasound, and ophthalmology, among others (8)(9)(10)(11)(12) , are especially favorable for the establishment of data transmission protocols with diagnostic purposes (13,14) .…”

Purposes: To validate a teleophthalmology mobile system aimed at improving and providing eye urgency screenings in remote and poor area settings in Brazil. The system enables one or more ophthalmologists to remotely examine a patient's condition and submit a decision describing the gravity of the case. If necessary, the patient can be forwarded to a hospital for further consultation. Methods: A cellphone (Nexus One model, with a 5 megapixel camera) was used to collect data and pictures from 100 randomly selected patients at the Ophthalmology Emergency Room located at the General Hospital of the Federal University of São Paulo (UNIFESP). Data was then sent remotely to an online recording system to be reviewed by an ophthalmologist who provided feedback regarding the state of ocular urgency. Results were then compared to the gold standard diagnosis provided at the hospital. Results: The diagnosis of urgency was given by two ophthalmologists: one in the hospital (gold standard) and one remotely. When we compared both diagnoses we obtained results of 81.94% specificity, 92.85% sensitivity, and 85% accuracy, with a negative predictive value of 96.72%. This work also included a processing time analysis, resulting in an average time of 8.6 min per patient for remote consultations. Conclusions: This study is the first that has used only a cellphone for diagnosing the urgency of ocular cases. Based on our results, the system can provide a reliable distinction between urgent and non-urgent situations and can offer a viable alternative for the servicing of underprivileged areas. In screening techniques, the most important outcome is to identify urgent cases with a high level of sensitivity and predictive negative value. Thus, our results demonstrate that this tool is robust and we suggest that a major study aimed to verify its efficiency in resource-poor areas should be initiated.
