Eye pressure reduction

About this calculator

Enter your baseline and current eye pressure to see the change in mmHg and as a percentage, and how the current reading compares with the target your eye doctor set.

What you need

• Your baseline eye pressure, and whether it was measured before or during treatment
• Your current eye pressure
• The target set by your eye doctor, if you have one

How it is calculated

Reduction = baseline − current. Percentage reduction = 100 × reduction ÷ baseline. Target difference = current − target. Values are calculated at full precision and rounded only for display.

What the result can and cannot tell you

Eye pressure is one part of glaucoma care. A lower number on its own does not show that glaucoma is stable; your eye doctor also follows the optic nerve and visual field, and sets each eye’s target from your clinical picture.
