Which of the following is listed as a risk factor that might prompt lowering the target IOP?

• A. Central corneal thickness
• B. Age
• C. Myopia
• D. Disc hemorrhage

Answer: (D)

A disc hemorrhage signals that the optic nerve is under active glaucomatous stress and may be progressing, so the target IOP should be lowered to reduce further risk of damage. These small hemorrhages at the disc margin reflect microvascular instability and ongoing structural stress on the neuroretinal rim, making tighter IOP control a prudent adjustment.

Other factors like central corneal thickness, age, or myopia influence risk or measurement but don’t provide as direct a, near-term cue of progression as a disc hemorrhage. Thin corneas can affect how we read IOP, and age or myopia affect overall risk, but disc hemorrhage specifically points to a need to reassess and potentially lower the target to protect vision.
