I usually make pPRP in periphery in patients with sever non proliferative retinophathy, and in patients with periphery ischemia in wide field angiography and low options for periodic control or bad metabolic control.

if there is a proliferative disease I do full PRP the same day.

In case of early proliferative changes including neovascularisation

In the compliant patient, I usually wait for early proliferative signs. Otherwise, I perform PRP in all severe non-proliferative cases.

The indication for routine Full PRP in diabetic patient is PDR. But I also do scatter PRP for severe NPDR cases if the patient is non-compliant or if the patient is coming from far distance and has lost the other eye from PDR .

I only do full PRP for high risk PDR and maybe in the fellw eye with severe NPDR. As for severe NPDR & low risk PDR i closely follw up the patients with strong advice to control diabetes and other co-morbid conditions. Moreover I emphasize to young patients the benefits of regular aerobic exercise and make life style changes. I am a non believer in scatter PRP and I perform full PRP if the patients fulfill the criteria.

I prefer scatterei PRP, has less damage to the reina, and better functional visual performances.

Earlier the better.
