For glaucoma suspects with an intraocular pressure (IOP) less than 22 mmHg, which statement best reflects treatment guidelines?

Explanation:
In glaucoma suspects with an IOP under 22 mmHg, treatment isn’t dictated by a single numeric cutoff. Whether to treat depends on the individual’s risk of progression to glaucoma, not just the IOP value. That risk is shaped by multiple factors: how the optic nerve head looks (cupping, notching, disc size), evidence of retinal nerve fiber layer thinning, and any functional changes on visual fields; plus patient-specific factors such as central corneal thickness (a thinner cornea can mean higher true risk), age, family history, race, and other ocular or systemic risks. Because these factors interact differently in each person, there isn’t a one-size-fits-all guideline. Some suspects with IOP below 22 may need treatment if their risk is high, while others with low risk can be managed with close monitoring. Risk estimates from studies like the OHTS help inform this balance. When therapy is pursued, the goal is often to reduce IOP by a meaningful percentage rather than hitting a fixed number.
