Ocular Hypertension

Ocular hypertension is when blood pressure in the eyes (intraocular pressure) is higher than normal due to an increase in fluid in the front of the eye. Ocular hypertension increases the risk for glaucoma.

Quick Answer

What it is

Ocular hypertension is when blood pressure in the eyes (intraocular pressure) is higher than normal due to an increase in fluid in the front of the eye. Ocular hypertension increases the risk for glaucoma.

How It Works

Ocular hypertension is elevated eye pressure (intraocular pressure/IOP) without any damage to the optic nerve or visual field loss. Normal IOP is 10-21 mmHg; ocular hypertension is typically defined as IOP >21 mmHg. It's important because elevated IOP is the main risk factor for glaucoma, a disease that damages the optic nerve and causes irreversible vision loss. However, not everyone with ocular hypertension develops glaucoma - only about 10% over 5 years without treatment.

CRITICAL: Ocular hypertension requires monitoring by an eye doctor (ophthalmologist or optometrist). Regular comprehensive eye exams including IOP measurement, optic nerve examination, and visual field testing are essential. Treatment decisions depend on IOP level, optic nerve appearance, visual field, corneal thickness, family history, and other risk factors. If treatment is needed, prescription eye drops (prostaglandin analogs, beta-blockers, etc.) are the mainstay. These supplements may support eye health but are NOT a replacement for prescribed IOP-lowering medications if indicated.

* Omega-3 Fatty Acids may support blood flow to the optic nerve and reduce inflammation. Some studies show an association between dietary omega-3 intake and lower glaucoma risk.

* Bilberry Extract contains anthocyanins that support ocular blood flow and may have neuroprotective effects for the optic nerve.

* Vitamin C is an antioxidant found in high concentrations in the aqueous humor. Some older studies suggest high doses may temporarily lower IOP.

* Magnesium may improve blood flow to the optic nerve and has shown some benefit in glaucoma studies.

* Ginkgo Biloba improves microcirculation and may have neuroprotective effects for the optic nerve.

* Coenzyme Q10 supports mitochondrial function in retinal ganglion cells.

* Alpha-Lipoic Acid provides antioxidant protection.

Expected timeline: These supplements support long-term eye health. They are not expected to significantly lower IOP like prescription medications. Regular monitoring every 6-12 months is essential.

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.

Type 2 Diabetes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.
