Metformin and Glaucoma

Key Discovery: Metformin and Eye Health

Researchers found that the common diabetes medication metformin may help protect against glaucoma. After studying over 24,000 patients, data showed that those taking metformin had a 19%
lower risk of developing the disease.

Why This Matters

  • New Prevention Method: Currently, the only way to treat glaucoma is by lowering eye pressure. Metformin could provide a new, additional way to protect vision.

  • Beyond Blood Sugar: The protective effect seems to work independently of how well a person's blood sugar or eye pressure is controlled.

  • Protecting Nerve Cells: Scientists believe the drug might work by directly preserving the nerve cells in the back of the eye and protecting the eye's natural drainage system.

Study Details

  • Long-term Evidence: The study followed participants for an average of 12 years.

  • Consistent Results: A broad review of existing medical data confirmed a consistent link between taking metformin and a reduced risk of glaucoma.

  • Next Steps: While these results are promising, researchers noted that more clinical trials are needed to fully confirm the benefits across different populations.

IMPLANTABLE COLLAMER LENS APPEARS BETTER THAN LASIK OR PRK FOR MODERATE TO HIGH MYOPIC PATIENTS

http://www2.cochrane.org/reviews/en/ab007679.html The results of this review suggest that the implantable lens (ICL) is are safer than excimer laser (the laser used in PRK and LASIK) surgical correction for moderate to high myopia in the range of -6.0 to -20.0 D and ICL is preferred by patients. ICL surgery resulted in better corrected visual acuity, better contrast sensitivity, and improved patient satisfaction. ICL may also be considered in cases where the patient has more moderate near-sightedness (in the range of -3.00 to -6.00). My personal experience with ICL gives me a high level of confidence in this procedure and the surgeon with whom I co-manage. All patients I have seen have been 20/20 or better. One patient was in the -6.00 range and the others in the -10 range! I see very little side effects. For more information, feel free to our office at 480-812-2211.

RINSING YOUR CONTACT LENS CASE IS NOT ENOUGH

Removal of biofilm from contact lens storage cases -- Wu et al., 10.1167/iovs.10-5796 -- Investigative Ophthalmology & Visual Science It has been conventional wisdom amongst eye doctors that most infections related to contact lenses actually originate from the contact lens storage case. I usually recommend rinsing the case after use and filling with fresh solution. However, it appears that thoroughly rubbing the inside of the case with clean fingers helps remove most of the biofilm on which the bacteria grow. I also usually recommend replacing one's case on a regular basis. I am surprised how many new patients come into my office with grimy, dirty contact lens cases. According to this study: "digital rubbing and rinsing, and/or wiping the lens cases with tissue are recommended. Air-drying and recapping the lens case lids after use without any additional cleaning methods or the use of antimicrobial cases should be discouraged."
