PRP has largely been the same for the last 40 years. The standard treatment is basically the same for all patients (4 + 6), which leads to some patients being either over or under treated. If treatment is inadequate, patients are in risk of disease progression and thus difficult vision loss (7). On the other hand, the treatment may cause side effects in the form of loss of visual field (8-9), night vision loss (10) and accumulation of fluid in the eye's macula (diabetic macular edema) (11).
