Positive aspect	References
High accuracy in diabetic retinopathy diagnosis	[16, 49, 74, 75]
Prevention of unnecessary referrals (reduction by as much as 75%)	[9, 14, 25, 68, 77]
High percentage (70%) of screening of diabetics in rural regions	[8, 28, 63, 67]
Improved medical care in remote regions	[20, 28, 67, 73, 81]
More diabetics receiving eye care with telemedicine than with traditional direct care scheme	[8, 9, 12, 54, 62, 74, 89, 91]
