Lutein with or without zeaxanthin vs placebo

Progression to visual loss (loss of 3 or more lines on logMAR chart) · people with AMD

Lutein with or without zeaxanthin showed no clear difference in progression to visual loss (loss of 3 or more lines on logMAR chart) compared with placebo (low certainty).

Blood pressure intervention/intensive blood pressure intervention vs placebo/standard blood pressure intervention

Change in visual loss associated with PSR: visual loss is defined by the deterioration of visual acuity of 3 lines or more with the Snellen chart · type 1 or type 2 diabetics

It is very uncertain whether blood pressure intervention/intensive blood pressure intervention changes visual acuity (loss of 3 lines or more) by 5 years compared with placebo/standard blood pressure intervention (very low certainty).
