VITAMIN B12 & FOLATE DEFICIENCY MAY INCREASE CRVO RISK

By Dr. Kevin -
Journal of Medical Case Reports Abstract 1752-1947-2-77 Malnutrition and bilateral central retinal vein occlusion in a young woman: a case report:

This report suggests that deficiency in Vitamin B12 and folate can increase risk of CRVO due to elevated homocysteine levels. It concludes:

"Vitamin B12 and folate deficiency can lead to elevated levels of homocysteine. We found a large amount of published data relating central retinal vein occlusion to elevated homocysteine levels, but there was a lack of conclusive evidence for this association Patients should be asked about their dietary history where a thrombotic event is suspected or confirmed."

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

By Dr. Kevin -

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."
