Laser for Diabetic Retinopathy


Laser treatment

The kind of laser treatment which is used to treat diabetic retinopathy is known as photocoagulation. Many of the people having laser treatment have very minute visual impairment. Others who have early or moderate maculopathy & proliferative retinopathy will also advantage from the laser treatment.
Laser treatment for the diabetic retinopathy has been a standard of the care for more than 30 yrs. Together with the effective screening, good blood glucose control & controlled blood pressure, it can successfully maintain the vision.

How does it work?

Tiny laser burns allow more oxygen & nutrients to reach retina, which will improves the blood circulation. This signals that are no need for 'new vessels' to be produced. You will need more than one treatment as vessels may start growing once again.

What’s the procedure?

  1. Initially you will have local anaesthestic & pupil-dilating eye drops inserted in your eye.
  2. A special contact lens will be positioned on the eye to hold the eyelids open & to allow the laser beam to focus into the retina
  3. The laser beam will be directed at the damaged areas of the retina.
  4. Small bursts of thin beams of laser light which seal the leaky blood vessels & destroy the abnormal new blood vessels in retina.

An eye specialist (ophthalmologist) will carry out the laser treatment & nearly always as outpatient procedure, and procedure will allows you to go to home afterwards. A session of the treatment can differ in length from one person to another person. Ask eye specialist how long the sessions will last & whether you need to come back for more treatment.
