An OHTS score of 5-15% indicates what about treatment?

• A. <5%
• B. 5-15%
• C. 15-25%
• D. 0-4%

Answer: (B)

OHTS uses a risk calculator to estimate the chance that ocular hypertension will progress to POAG within five years. The result is a percentage that places the patient into a risk category. A score in the 5-15% range signals a moderate risk of progression. In this band, the typical approach is to have a detailed discussion with the patient about the risks and benefits of treatment and to consider initiating IOP-lowering therapy, since lowering IOP has been shown to reduce the likelihood of conversion.

If the risk were below 5%, it would be considered low risk and observation or less aggressive management might be chosen. If the risk were above 15%, that would indicate higher risk and a stronger push toward treatment. So, the 5-15% category best describes a moderate-risk situation where treatment is commonly contemplated.
