IRIDEX Announces Long-Term Glaucoma Efficacy Data for Patients Treated with MicroPulse® P3 Probe Technology

The data, presented by Maria Cecilia Aquino, M.D., and Paul Chew, M.D., and titled "Long-term Efficacy of MicroPulse Diode Transscleral Cyclophotocoagulation in the Treatment of Refractory Glaucoma," were the results of retrospective case studies that aimed to evaluate and present the long-term efficacy of MicroPulse transscleral cyclophotocoagulation (MPCPC) in subjects with refractory glaucoma treated from a prior prospective trial concluded in 2014.

"Dr. Aquino and I are thrilled to have successfully followed this cohort of patients over the course of six and a half years to determine the long-term benefits of the MicroPulse technology for patients with refractory glaucoma," said Dr. Chew, associate professor, National University Hospital and National University, Singapore.  "We can now say with confidence that MicroPulse is not only safe and efficacious for the acute reduction of intraocular pressure (IOP), but is also an excellent option for ophthalmologists looking to provide durable relief to their patients."

A study population of 14 subjects with refractory glaucoma treated from the initial prospective exploratory study of 23 patients were reviewed.  IOP and number of medications on the last review visit were recorded.  Success was defined as 30 percent or more final IOP reduction from baseline. Mean pretreatment IOP was 43.3 mmHg (range 22-73) and IOP at last follow-up was 24.8 mmHg (range 12-56).

"These outcomes represent a significant milestone for MicroPulse and IRIDEX, signifying the longest-term data set we have to date for this system," said President and CEO Will Moore.  "To be able to showcase six and a half years worth of efficacy data and decreased medication loads, even in a small set of patients, is a testament to our mission to provide a safe, non-incisional, repeatable and more cost-effective alternative to treating glaucoma.  It should also be noted the patients were treated with the MP3 on average 4 times during the six and a half years."

About MicroPulse Technology
MicroPulse is a tissue-sparing laser delivery therapy that works by electronically "chopping" the laser emission into trains of microsecond pulses. This enhances the physician's ability to more precisely control the laser effects on target tissues, offering the potential for ocular treatment with less collateral effects than conventional laser treatments.
