eOphthalmology can be defined as the use of information and telecommunications technologies to provide or support a group of activities related to ophthalmic care. The same concept applied to ophthalmic care would be eOphthalmology. This paper describes the current state of eOphthalmology-based models in diabetic retinopathy screening and in the diagnosis and follow-up of chronic glaucoma and age-related macular degeneration. Furthermore, the main advantages of these models and the technological requirements needed for their implementation are described. Finally, a prediction of the impact of eOphthalmology on the future of health care is offered.

The efficient harvesting of triplet excitons is key to realizing high efficiency blue fluorescent organic light-emitting diodes (OLEDs). Triplet-triplet annihilation (TTA) up-conversion is one of the effective triplet-harvesting strategies. However, during the TTA up-conversion process, a high current density is necessary due to the competitive non-radiative triplet losses.

Reactive oxygen species (ROS) play a critical role in regulating various physiological processes. To gain a comprehensive understanding of their distinct functions in different physiological events, it is imperative to detect binary ROS simultaneously. However, the development of the sensing method capable of binary ROS detection remains a significant challenge.

Electrochemical biosensors can provide an economical, accurate and rapid method for early screening of disease biomarkers in clinical medicine due to their high sensitivity, selectivity, portability, low cost and easy manufacturing, and multiplexing capability. Tear, a fluid naturally secreted by the human body, is not only easily accessible but also contains a great deal of biological information. However, no bibliometric studies focus on applying electrochemical sensors in tear/eye diseases.
