Ocular hypertension symptoms: what to know

Ocular hypertension means the pressure inside the eye is higher than expected, without necessarily showing damage to the optic nerve. It is different from glaucoma, although continued pressure can increase the chance of optic-nerve damage. Blurred vision, eye discomfort, or halos are not reliable ways to identify it because many people feel entirely well. A clinician may measure pressure, inspect the optic nerve, test the visual field, and assess the drainage angle.

Arrange a comprehensive eye examination if you have been told your eye pressure is raised or you have missed routine checks. Take a list of medicines and mention any previous eye injury, steroid use, or family history of glaucoma. Keep follow-up appointments even when your sight seems unchanged; pressure readings can vary and need interpretation alongside the optic-nerve findings. Do not stop prescribed eye medicine without speaking with the prescriber.

Seek urgent eye care for sudden severe eye pain, a markedly red eye, sudden blurred or lost vision, coloured rings around lights with nausea, or a severe headache with vomiting. These symptoms can signal a rapid rise in eye pressure or another emergency and should not be monitored at home. A gradual change in sight also deserves prompt assessment, even if there is no pain.

Ask which pressure readings were recorded, whether the optic nerve and visual field look healthy, how often monitoring is needed, and which symptoms should prompt same-day review. You can also ask whether any current medicine or steroid treatment could affect eye pressure.
