Pigmentary Maculopathy and Elmiron

Riddle Brantley LLP   |  May 14, 2020   |  

Alarming research has revealed a connection between the popular bladder medication, Elmiron, and a newly discovered eye disease called pigmentary maculopathy. Does Elmiron cause pigmentary maculopathy?

What is Pigmentary Maculopathy?

Pigmentary maculopathy is a newly discovered eye disease. It was first discovered by researchers at Emory Eye Center. This maculopathy is an eye disorder that affects the macula, which is the central part of the retina. Pigmentary maculopathy can cause blindness.

Pigmentary Maculopathy and Elmiron - Riddle & BrantleyNotably, researchers have determined that pigmentary maculopathy “can be mistaken for other well-known macular disorders, such as pattern dystrophy and age-related macular degeneration.”

However, research has connected the bladder medication Elmiron to pigmentary maculopathy.

In a recent study presented to the American Academy of Ophthalmologists (AAO), researchers found that Elmiron may cause pigmentary maculopathy, among other serious eye injuries, including retinopathy and blindness.

Symptoms of Pigmentary Maculopathy include:

  • Vision loss
  • Dark spots in the field of vision
  • Difficulty adapting to dark environments
  • Distorted lines in the field of vision
  • Muted colors
  • Eye color changes

What is Elmiron?

Elmiron (pentosan polysulfate sodium or “PPS”) is a popular bladder medication and currently the only prescription drug approved by the FDA for treating a relatively uncommon condition called interstitial cystitis. Interstitial cystitis is a condition resulting in bladder pain and discomfort.

Recent research has revealed alarming connections between Elmiron and serious eye damage. In a study presented in 2020, researchers found that roughly one-quarter of patients taking Elmiron exhibited evidence of serious eye damage, including pigmentary maculopathy, retinal maculopathy, and partial and full blindness.

The 2019 study by Kaiser Permanente found that 25 percent of patients who had taken Elmiron for a minimum of 5 years showed signs of serious eye damage. The study found that eye damage increased with the dosage of Elmiron.

Does Elmiron cause pigmentary maculopathy?

Pigmentary Maculopathy and Elmiron Eye Damage - Riddle & BrantleyResearch has found that many patients taking Elmiron exhibited symptoms of pigmentary maculopathy. Women who had been taking Elmiron at 200-400 mg daily doses for a median of 15.5 years were most affected by potentially Elmiron-caused pigmentary maculopathy.

At 7 years, Elmiron patients studied by researchers at Emory Eye Center had significantly increased odds of developing pigmentary maculopathy.

The study concluded:

“We describe a novel and possibly avoidable maculopathy associated with chronic exposure to PPS [Elmiron].”

Emory Eye Center researchers, 2019 study

A 2019 Harvard report published in Investigative Ophthalmology and Visual Science also found “a new layer of concern by demonstrating progressive maculopathy continuing for up to 6 years after the cessation of [Elmiron].”

Based on this evidence of pigmentary maculopathy potentially caused by Elmiron, in October 2019, Health Canada issued a warning:

“In the post-market setting, pigmentary maculopathy has been reported with chronic use of Elmiron. Visual symptoms included difficulty reading and prolonged dark adaption.”

-Health Canada (Canadian Health Service)

The warning encouraged patients taking Elmiron to have regular ophthalmic examinations to check for evidence of pigmentary maculopathy and other serious eye damage. According to the report, if pigmentary maculopathy is discovered, patients should consider discontinuing use of Elmiron.
