“…It is also used by healthcare professionals to offer services such as assessment of remote radiology images and distribution of lab results or consultation with clinical specialists [20,21]. Some of its subset topic include teleoncology, telediagnosis of heart diseases, telediagnosis of skin diseases, teleradiology, and teleophthalmology [22,23]. Teleophtalmology is a branch of telemedicine that deals with provision of eye care by digital medical equipment and telecommunication technology [24].…”

Background The present study describes the development and identity phases of a teleophthalmology system used for screening of diabetic retinopathy. Methods A questionnaire was used to identify the main factors necessary for diagnosis of diabetic retinopathy and the features required for a teleophthalmology system. In the second phase, a web-based prototype of the system was designed using the data collected in the previous phase. In the final phase, the system was optimized based on the users' ideas and comments; then, it was evaluated through a standard usability testing questionnaire.Results The results showed that the lowest average percentages were related to ethnicity (61%), optometrist's office address (61%), and consultant physician's office address (65%). A web-based prototype was designed using the Visual Studio and Dreamweaver programming tools. This system comprised patient identity data, medical history, clinical data, and retinal images of the patient. The mean score of usability testing and user satisfaction including specialists, residents, and optometrist was 7.3, 7.1 and 7.3 (out of a total 9), respectively. The evaluation results revealed that the system was classified as good. Conclusion The telescreening system suggested in the current study could be helpful in timely diagnosis. Moreover, it would reduce the treatment costs and complexities. Regardless of the positive points of telemedicine systems, one of the most challenges in this study was the Internet infrastructure to design and apply the system. The future studies, therefore, could focus on the application of cell phone technology for rendering teleophthalmology.

“…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) . Ophthalmology, for example, can greatly benefit from telemedicine (15,16) , as it is crucial to identify patients that present urgent cases in order to avoid morbidity and permanent disorders (17) . Thus, it is very important to differentiate between these two groups of patients.…”

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.

“…As a specialty heavily reliant on visual information, ophthalmology is amenable to telemedicine applications. [2][3][4][5] Teleconsultation, a method within telemedicine, focuses on assisting a remote provider by offering expert opinions and diagnostic support regarding the treatment of a patient. 6 Because medical providers accompanying deployed military personnel may have limited experience in specialty areas like ophthalmology, teleconsultation is of particular interest.…”
