Ocular Hypertension (OHT)
It is a condition where the pressure inside your eye is elevated higher than 21 mmHg without detectable glaucomatous changes or damages in the eye. The normal intraocular pressure (IOP) range is 11 – 21 mmHg.
Patients with OHT should be monitored closely as they are also known as “glaucoma suspect” and have high risk to get glaucoma.
It is an eye disease where there is progressive optic nerve damage (neuropathy) characterised by progressive loss of retinal nerve fibre layer, thinning of neuro-retinal rim and irreversible peripheral vision loss. It is usually caused by fluid build ups inside the eye due to various factors and give rise in IOP of more than 21 mmHg.
Common Types of Glaucoma:
- Primary open angle glaucoma (POAG) – caused by slow progressive fluid builds up over time due to blocked or clogged eye fluids drainage channels.
- Acute angle closure glaucoma (AACG) – caused by sudden fluid builds up due to blocked or clogged eye fluids drainage channels.
- Secondary glaucoma – caused by other underlying eye conditions such as uveitis (eye inflammation)
Signs and Symptoms
- Painful red eyes
- Blurred vision
- Peripheral visual field loss
- Haloes around light
- Nausea and vomiting
- Sudden vision loss
*This condition may even be ASYMPTOMATIC until at the advanced stages!
