Yes, you can often still drink coffee with glaucoma, but moderation is key, especially if you have a strong family history or advanced disease, as caffeine can temporarily raise intraocular pressure (IOP). Moderate intake (around 2-3 cups or up to 400mg daily) is generally considered safe for most, but some studies suggest heavy daily coffee intake might increase glaucoma progression risk, particularly for genetically predisposed individuals, so discuss your specific caffeine limits with your ophthalmologist.
For most people with glaucoma, a single cup of coffee causes only a modest, temporary increase in eye pressure that returns to baseline within a few hours. Current research suggests moderate caffeine intake (200 to 300 mg daily) does not significantly worsen glaucoma for most patients.
Some studies suggest caffeine increases intraocular pressure, cholesterol levels, and blood pressure. You'll want to limit the amount of (or replace) coffee, green tea, dark chocolate, soda, and energy drinks in your diet.
The anti-oxidative and anti-inflammatory properties of green tea catechins in vitro and in vivo have been well proven. They could be a potential treatment ameliorating retinal ganglion cell degeneration in glaucoma.
Heavy caffeine intake should be advised against due to its transient elevations in IOP, especially in genetically predisposed patients or those with a positive family history of glaucoma. Chronic alcohol consumption can lead to many systemic complications and increased risk of glaucoma.
Sugary Drinks
Drinks like soda, energy drinks, sweet tea, and lemonade contain high amounts of sugar. Consuming large amounts of sugar increases your risk of type 2 diabetes and heart disease, which can cause diabetic retinopathy and age-related macular degeneration (AMD).
“Strict adherence to medication is the single most important thing a patient with glaucoma can do to keep their vision from worsening,” Yohannan says.
The rule of 5 is a simple rule for detecting retinal nerve fiber layer (RNFL) change on spectral-domain OCT (SD-OCT), in which a loss of 5 μm of global RNFL on a follow-up test is considered evidence of significant change when compared with the baseline.
According to a NIH study, women consuming fresh peaches and oranges in excess of two servings per week reduced their odds of developing glaucoma. Orange consumption led to 82% reduction in glaucoma development, while peaches served to cut this risk by 70% percent.
Other things that can temporarily raise eye pressure include lifting heavy weights, playing wind instruments, wearing a tight necktie or using swimming goggles. If you go swimming, it's best to wear larger goggles, because smaller ones press on the orbit of the eye which increases eye pressure.
Causes of Glaucoma
Aerobic exercises, like walking, running, and swimming, stand out for their ability to significantly lower IOP. These exercises enhance cardiovascular fitness, improving blood circulation throughout the body, including the eyes.
Nicotinamide/Niacinamide (Vitamin B3)
Nicotinamide (also known as niacinamide) has recently shown significant potential as a novel treatment for glaucoma. It was postulated as a neuroprotective agent for glaucoma in 2017 by Williams and colleagues.
If you've been diagnosed with glaucoma, then your ophthalmologist might make the following suggestions: Sleeping in an upright position: Because it's known that IOP rises when you're horizontal, sleeping more upright may help reduce this.
Exercise regularly.
Your eyes need healthy blood circulation and oxygen to fuel good vision. Exercise—anything that gets your heart rate up and the blood pumping from a brisk walk to a run or a Zumba class—benefits your eyes because it promotes good circulation.
Seniors (70+ years old): The normal eye pressure for 70 year olds and beyond may still fall within the 10 to 21 mmHg range, but it's closely monitored for any increases, as they are more susceptible to eye conditions like glaucoma.
Stage 1: Glaucoma begins with any alteration to your drainage system, which leads to increased intraocular pressure.
Glaucoma suspects and patients can measure their IOP using the HOME2 tonometer during normal activities as directed by their doctor. The iCare PATIENT2 mobile app provides the patient a graphical view of their IOP measurements history which can increase compliance with their treatment plan and follow up appointments.
“Steroids are the main medicine that can raise eye pressure for patients with open-angle glaucoma,” Dr. McKinney says. Taking steroid drugs in any form – orally, topically, through an inhaler or IV – can worsen glaucoma for these patients. Steroids applied closest to the eye carry the highest risk.
Medications to lower pressure in your eyes include:
But most forms of glaucoma are treatable, especially when diagnosed early. And with care and careful management, it's possible to delay — or even prevent — permanent vision loss.
A high BMI has been linked to intraocular pressure and glaucoma. It's best to avoid foods high in saturated fats such as butter, cheese, and whole milk, and such fatty meats as salami and bacon. Caffeinated coffee increases intraocular pressure, so moderating consumption may be a good idea.
Moderate coffee consumption does not directly cause vision impairment or eye damage. However, heavy caffeine intake may lead to temporary visual disturbances, such as blurred vision or eye twitching, in some people.
Some of the most common causes that damage eyesight include:
Vitamin D has been proposed to influence intraocular pressure and decrease retinal ganglion cell degeneration. Based on these findings, vitamin D has been suggested to prevent or reduce the severity of primary open-angle glaucoma (POAG), which is the most common form.
