The following is a list of risk factors for primary open-angle glaucoma (POAG), the most common form:
- Older age (>40)
- Black race (glaucoma strikes earlier and progresses faster)
- Family history (if a first-degree relative is affected, you’re at increased risk)
- Diabetes (people with diabetes are twice as likely to develop glaucoma as non-diabetics)
- Vascular diseases (i.e. both hypertension and hypotension can increase your risk)
- Raised intraocular pressure (fluid pressure inside the eye)
- Certain ocular conditions (i.e. shortsightedness, certain retinal detachments, central retinal vein occlusion)
- Long-term use of the oral contraceptive pill
Asian individuals have a higher risk of developing acute angle-closure glaucoma (AACG). The faster rise in the pressure can rapidly cause more severe damage to the optic nerve.
Risk factors that have been identified for acute angle-closure glaucoma are:
- Belonging to certain racial groups (Chinese, South East Asians, Eskimos)
- Older age (>60)
- Female gender (women are four times more likely to be affected than men)
- Family history (if a relative is affected, you’re at increased risk)
- Short eyes
- Far-sighted eyes
