Devouring Kale and Eye Health Supplements? That May Be Too Much of a Good Thing

Eye doctors regularly prescribe AREDS-2 (age-related eye disease study)
eye health supplements to slow the progression of macular degeneration.
However, a recent
case report published in
JAMA
Ophthalmology
revealed what happened to one woman who took supplementation too far.
Yes, you can overdose on nutritional supplements.

According to Key-Whitman Eye Center’s Arlington eye doctor
Ronald Barke, M.D., the
JAMA report highlights why we need to use common sense and consult a doctor
before adding supplements to our diets.

As Dr. Barke explains, “The woman identified in the report ended
up with crystal deposits in the macular region of her retina. Unbeknownst
to the patient (who didn’t have macular degeneration), she was overdosing
on lutein by consuming double the recommended daily dosage of lutein supplements
and drinking a daily smoothie loaded with lutein-rich foods like kale
and spinach.”

While the
JAMA report does serve as a cautionary tale, Dr. Barke says the upside of lutein
supplements for
treating macular degeneration – the AREDS-2 formula in particular – outweighs the risks.
Along with lutein, the AREDS-2 formula includes nutrients, vitamins, zinc
and other antioxidants that studies show
support eye health.

“There are millions of patients who successfully take lutein supplements
like AREDS-2 to manage macular degeneration. This case involved one patient
who took too much of a good thing. Lutein supplements have proven to be
a very effective treatment for slowing the progression of vision loss
caused by this disease,” explains Dr. Barke.

Dr. Barke discusses the benefits of the antioxidant-rich AREDS-2 formula
for patients with macular degeneration.

So How Can You Avoid Getting Too Much Of A Good Thing?

Dr. Barke encourages patients to speak frankly with their eye doctor about
their diet and any medications or supplements they take. As he explains,
“At Key-Whitman we regularly review our macular degeneration patients’
dietary, medication and supplementation history to help ensure we prescribe
the appropriate type and dosage of supplements.”

Early diagnosis and treatment of macular degeneration is key for staving
off vision loss caused by the disease. People who are at higher risk for
macular degeneration should schedule – at a minimum – annual
screenings with an eye doctor. Main risk factors include:

  • Age 50 and above
  • Family history of macular degeneration
  • Smoker or former smoker
  • Obesity

Once diagnosed, the eye doctor can recommend a variety of treatments for
the patient, based on the type of macular degeneration – wet or
dry – the doctor diagnoses.

Dr. Barke discusses the importance of early screening for macular degeneration.

Don’t Let
Unnecessary Fears About Macular Degeneration Deter You From Seeing An Eye Doctor

Dr. Barke finds that patients with macular degeneration or those who are
at risk for the disease have two unnecessary fears about the disease that
deter them from getting an eye exam.

No. 1: Patients are concerned they will go completely blind.

No. 2: Patients have worries about the treatments available for macular degeneration.

According to Dr. Barke, patients don’t need to be fearful. As he
explains, “At Key-Whitman, we hear these concerns all of the time,
but we also know how to allay our patients’ fears. The most important
thing we tell patients is that you can stave off vision loss when macular
degeneration is diagnosed early.

“In addition, supplements work very well with an early diagnosis.
Plus, laser procedures and the medicine we instill into the eyes for the
wet form of macular degeneration can be extremely effective. We also keep
patients comfortable and pain-free during these procedures by applying
a numbing solution to the eye.”
