Study: Bilberry/Pine Bark (2010) & Glaucoma (Mirtogenol )



A study published in a 2010 issue of the journal Clinical Opthamology examined the effects of Mirtogenol in a group of 79 patients living with "asymptomatic ocular hypertension". The participants were separated into three groups:

  • received 80 mg of Mitroselect bilberry extract and 40 mg of Pycnogenol daily
  • applied a medicinal eye drop (Latanoprost)
  • utilized both treatments

The trial lasted a total of 24 weeks and yielded the following results:

  • The Mirtogenol group lowered their intraocular pressure (IOP) from 38.1 to 29 mmHg or 24%.
  • The Latanoprost patients found an IOP reduction from 37.7 to 27.2 mmHg or 28%.
  • The combination group began with an IOP of 38 mmHg and ended with an IOP of 23 mmHg – a 40%
  • Healthy or normal eye pressure should range between about 10 to 21 mmHg.

In conclusion, the authors reported that, "The combination of both was more effective for lowering IOP and the combination yielded better retinal blood flow. No serious side effects occurred during the study, apart from standard side effects in patients related to Latanoprost". According to the National Institutes of Health, Latanoprost may cause the following adverse reactions in some users: dry eyes, eye color changes, irritation and redness of the eyelids.
