In suspected glaucoma, intraocular pressure is typically above which value?

• A. Above 21 mmHg
• B. Below 12 mmHg
• C. Between 10-15
• D. 40-50

Answer: (A)

In glaucoma assessment, the pressure inside the eye is considered elevated when it exceeds about 21 mmHg. Normal IOP typically ranges from roughly 10 to 21 mmHg, so values above 21 raise concern for glaucoma and lead to closer evaluation of the optic nerve and visual fields. It’s important to remember that some people can have glaucoma with normal pressures, and not everyone with high pressure develops glaucoma, so diagnosis also relies on optic nerve appearance and functional testing. Therefore, the value above which intraocular pressure is typically considered elevated is greater than 21 mmHg.
