In setting a target IOP, which pair of concepts correctly describes the methods?

• A. Age and race
• B. Visual field status alone
• C. Color of iris
• D. Percent reduction from pre-treatment max IOP and IOP range

Answer: (D)

Target IOP is determined by how much you aim to lower from the eye’s pre-treatment maximum and by accounting for the range of pressures the patient experiences. Using a percent reduction from the pre-treatment max IOP provides a clear, individualized goal for how much to lower the pressure. At the same time, considering the typical IOP range ensures the target is achievable across diurnal variations and daily fluctuations, helping to prevent progression while avoiding overly aggressive targets that might risk hypotony. Factors like age, race, or iris color don’t set the target, and while visual field status reflects disease severity, it doesn’t define the specific reduction percentage used to establish the target.
