What is Ocular Hypertension (OHT)? - Glaucoma Glossary

Ocular hypertension is clinically defined by consistently elevated intraocular pressure (>21 mmHg) in the absence of any detectable optic nerve damage or visual field defects.

What it means for the patient

This means your eye pressure is higher than average, but the "sneak thief" of glaucoma hasn't actually stolen any nerve fibers or vision yet. You are a suspect, and must be monitored, but you do not currently have the disease of glaucoma.

Clinical significance

Patients with OHT are categorized as glaucoma suspects. Determination to initiate prophylactic pressure-lowering therapy relies heavily on comprehensive risk calculators incorporating CCT, age, and baseline IOP levels derived from the OHTS framework.

How it is tracked

OHT patients are loaded into Glaucoma One without active disease slopes; instead, they are monitored purely on structural (OCT) stability and IOP adherence to safe bands.
