What is Tmax used to determine in these guidelines?

Explanation:
Tmax is the highest intraocular pressure observed during a diurnal IOP curve, capturing the peak pressure a patient reaches over the day. The guidelines use that peak value as a reference point to determine how much pressure to lower. By expressing the target as a percentage reduction from Tmax, you tailor treatment to how high the patient’s worst-case pressure gets, not just a single reading. For example, if Tmax is 30 mmHg and the plan is a 20% reduction, the target IOP would be 24 mmHg (30 × 0.80). This method emphasizes lowering the maximum pressure to reduce the risk of glaucomatous damage, which is why the percent reduction from Tmax is the measured goal. Baseline IOP is a starting point, but Tmax specifically informs how much reduction is aimed for relative to the peak. Target IOP by age is a general guideline concept, not derived from Tmax itself, and IOP after surgery depends on surgical outcomes rather than the Tmax-based reduction calculation.
