Please let me know if there is any difference between diabetic retinopathy and hypertensive retinopathy?
Yes, big difference. Aside from being caused by 2 separate diseases, eye manifestations are distinct as well.

Diabetic eye disease affects the smaller capillary vessels, causing leakage and/or blockage of blood. If advanced, diabetic disease may require laser treatment or surgery.
