Which of the following is an example of a risk factor signaling treatment in glaucoma suspects with IOP <22?

• A. Very Thin CCT
• B. Excellent Visual Acuity
• C. Normal CCT
• D. Perfectly Symmetric Discs

Answer: (A)

Thin central corneal thickness signals higher risk in glaucoma suspects even when IOP is below 22. A very thin cornea is linked to a greater likelihood of future glaucoma progression and, importantly, can cause the measured IOP to underestimate the true pressure. This combination—thin CCT plus low-normal IOP—makes treatment more justifiable to protect the optic nerve.

Other options don’t carry the same risk implication in this scenario. Excellent visual acuity and normal CCT suggest stable function and no added risk from corneal thickness. Perfectly symmetric discs imply a lower chance of existing glaucomatous damage at this stage.
