Non-proliferative diabetic retinopathy (NPDR) is a condition where minuscule retinal capillary vessels start dysfunctioning and releasing a substance called vascular endothelial growth factor (VEGF), that causes the retinal vessels to leak which results in bleeding or swelling and prevents clear image formation. The objective of retinal laser treatment in case of NDPR is to stop the vessels from leaking and prevent further loss of vision. This is not as major a surgery as it sounds; and has grown to become common in today’s world. It is an outpatient surgery, with no major restrictions and very low-risk rate.
Laser treatment for retinopathy is a painless procedure that lasts anywhere from a few minutes to half an hour. It is advisable to undergo doctor consultation before opting for the surgery. Your doctor will provide you will all necessary details about the process and will help you understand the cause and effect of NPDR.

How it Works
Laser photocoagulation creates tiny retinal burns to seal off the leaking vessels and reduce swelling. The laser used for Retinal Laser Treatment NPDR can vary in wavelength (color) and is decided upon by considering each individual case. The effect of the bright flash from the laser beam wears down in a few hours after the surgery and the vision is expected to go back to normal in about four weeks’ time. With regular follow-up and check-ups, you can track your healing process. Be sure to not miss any consultation sessions at least for the first month to avoid any subsequent after-effects. Take all the necessary precautions as prescribed by the doctor.
