Modalities of Teleophthalmology

There are three main modalities of teleophthalmology: 'store and forward', real-time visits, and remote monitoring (Table 1). Store and forward technology is the most common modality of telemedicine used in ophthalmology, and refers to images or documents that are taken and forwarded to a clinician for review at a later time. For example, a physician reviews slit lamp images sent to them, after which they can then relay the findings back to the patient via a patient portal or another modality. Real-time telemedicine offers live audio or video consultation in real-time and is the closest telemedicine equivalent to an in-person office visit. Through this modality, it is possible for a clinician to get a thorough history from the patient and visually examine the eye. Lastly, remote monitoring, allows physicians to continuously collect health data from patients as they go about their daily lives so that they can monitor and manage chronic conditions. One example is a contact lens that can continuously monitor changes in intraocular pressure for glaucoma and transmit data to a physician.[32] These three modalities can help with screening, diagnosing, and monitoring ophthalmology conditions in emergency and outpatient settings.
