One More Holiday Concern: Your Vitamin D Level May Be Low

Monday, December 10th, 2012

The most readily available source of vitamin D is the sun’s UVB rays.  With cold weather comes more clothing, less outdoor time, and shorter days; possibly resulting in some of our lowest vitamin D levels of the year. Some experts are concerned that the increased use of sun screen is making vitamin D deficiency a year round concern.

Role of vitamin D:

  • promotes calcium absorption in the stomach
  • maintains serum calcium/phosphate levels
  • promotes bone growth/remodeling
  • linked with decreased risk of cancer, Crohn’s,                 depression, type 1 diabetes, MS, autism, and prostate   hyperplasia

Vitamin D and your eye:

General guidelines:

  • under 1, 400 IU
  • between 1-70, 600 IU
  • over 70, 800 IU

Those at highest risk of vitamin D deficiency:

  • diabetic individuals
  • those with macular degeneration
  • homebound individuals
  • people who have undergone gastric bypass
  • those with fat absorption problems
  • elderly individuals

If you think you are at risk for vitamin D deficiency, then ask your doctor about having your serum levels tested.  It is generally accepted that levels below 30 ng/mL are inadequate and levels above 50 ng/mL are sufficient.

Macular Degeneration Linked To Hearing Loss

Sunday, April 3rd, 2011


Macular degeneration has been linked to hearing loss in a recent study in Turkey.  All subjects were fifty or older and had eye and hearing examinations.  Analysis between fifty macular degeneration subjects was compared to forty-three normal subjects.  The macular degeneration group reported 50% mild, 20% moderate, and 6% severe hearing loss.  The normal group reported 35% mild, 5% moderate, and none with severe vision loss.  Further analysis showed greater hearing loss in subjects with dry macular degeneration vs wet macular degeneration.  Researchers concluded age-related hearing loss is more common in those with macular degeneration.

An Optometrist Beyond The Optical

Monday, March 28th, 2011


This post will describe what an Optometrist does beyond the optical of eyeglasses and contact lenses. Optometrists detect, diagnose, and treat vision conditions and eye diseases.


Procedures to remove foreign bodies such as metal from the surface of the eye or under the eyelid.


Pre-operative and post-operative care for Lasik and cataract eye surgery.


Cataracts, diabetic eye complications, glaucoma, macular degeneration, and retinal tears and detachments can all be detected through routine eye examinations by an optometrist.


Conjunctivitis, dry eye, glaucoma, macular degeneration, and uveitis are just some of the eye diseases that are routinely managed by optometrists.
