What do you think of preventive photocoagulation of the peripheral retina?

[mariposa87]

My doctor suggested I should do laser photocoagulation in my left eye  of one part of my peripheral retina- the temporal quarter. Not because I have some holes or tears in there , but because I am severy myopic (-15)and already had a retinal detachment in the temporal area in the right eye. In this way he wants to prevent RD in the left eye. My questions are:
-does such  photocoagulation really can prevent anything?
-is it risky?
-will it in any way affect my vision if it is only temporal? I am not sure how much in the periphery the laser line will be
-do you think it is a good idea if I don't have any tears or holes yet in this area?

what are the possible complications of this procedure?it will not be 360 degrees only one quadrant of peripheral retina

Because highly qualified retina surgeons do not agree on which conditions in which patients need to be treated..  JCH MD

why is it controversial?

I would suggest you get a second opinion from another retina surgeon. The treatment of holes, tears, lattice, retinoschesis and a whole host of retina problems is very controversial. Treating normal retina without any pathology doubly so. I cannot answer your questions over and above this.  If necessary get a 3rd opinion so you understand your options.
