For many people, their day doesn’t begin until they’ve had their hot cup of coffee. But does their beloved brew heighten their risk of developing glaucoma? As for patients who’ve already received a glaucoma diagnosis—should they steer clear of all caffeine?
At Dolman Eyecare Centre, we frequently receive these types questions from our patients, especially if they have a family history of glaucoma. If you or a loved one has been diagnosed with glaucoma, Dolman Eyecare Centre can help.
But First, What Is Glaucoma?
Glaucoma is a group of eye diseases characterized by increased pressure within the eye. While ocular pressure affects all structures of the eye, it can severely damage the optic nerve, resulting in vision loss.
There are two main types of glaucoma: open-angle glaucoma and angle-closure glaucoma.
Glaucoma is a leading cause of preventable blindness and vision loss, and often starts with no noticeable symptoms. That’s why regular eye exams are so vital.
Does Caffeine Affect Glaucoma?
Several studies have been conducted to determine whether there is a link between caffeine and the development and progression of glaucoma. While there isn’t yet a unanimous agreement, researchers generally agree that heavy caffeine intake can significantly increase your risk of developing glaucoma, especially if you are genetically predisposed to the disease.
One study published in the Journal of Glaucoma observed the effects of caffeine and coffee-drinking in patients with open-angle glaucoma. They found that intraocular pressure (IOP) was higher among those in the coffee-drinking group, who consumed at least 2 cups of coffee a day.
Another study found that heavy coffee drinkers (5 or more cups of caffeinated coffee per day) were more likely to develop glaucoma than those who don’t drink coffee.
In contrast, a third study (that used information from the National Health and Nutrition Examination Survey) found that caffeinated coffee was not a risk factor for glaucoma. Even more noteworthy: those who regularly drank hot, caffeinated tea had a lower risk of glaucoma. The researchers theorized that the antioxidants in tea counteracted the caffeine.
So, what’s the bottom line?
If you have glaucoma or if it runs in your family, speak to your eye doctor about limiting your caffeine intake as a preventative measure.
