ABSTRACT
There are two modes of delivery in telemedicine. One is real-time video conferencing, which is widely used for emergency and psychiatry consultations. Real-time consultations require high-bandwidth and scheduling. They need both clinician and patient to be present at the same time. This may be not possible in the case of specialists like ophthalmologists. In ophthalmology, high-resolution color images are required to capture the fine detail in the eye. Image files can be large and transmission of these high-resolution images can be time intense. Therefore, teleophthalmology is normally not suitable for video conferencing.
