Metabolic syndrome, a group of conditions that increases the risk of developing type 2 diabetes, heart disease, and stroke; has also been linked to increasing the risk of glaucoma.

Glaucoma is an eye condition that causes damage to the optic nerve resulting in vision loss.  It generally occurs due to elevated pressure within the eye and has few, if any, symptoms until its more advanced stages.

A longitudinal cohort study published in Ophthalmology, included 2,182,135 members enrolled in a managed care network who received an eye examination between 2001 and 2007.  Data analysis showed the following increased risk of developing glaucoma:

  • High Cholesterol  5%
  • Obesity 15%
  • High Blood Pressure 17%
  • Diabetes 35%
  • Diabetes & High Blood Pressure 48%

3 Common Causes of Conjunctivitis

Thursday, July 21st, 2011

NGC 6543: The Cat's Eye Nebula Redux (Also known as the Cat's Eye, this planetary nebula is located about 3,000 light years from Earth.)

Conjunctivitis is an inflammation of the bulbar conjunctiva (white portion of the eye) and commonly presents with sticky eyelids, watery or mucous discharge, redness, and irritation.  This post will discuss 3 common forms of conjunctivitis and what to do about them.

1.  Viral Conjunctivitis or “Pink Eye”

Viral in origin and highly contagious.  Most garden variety forms only last a few days but more virulent forms can have effects that last a month or even longer.  Redness is typically mild giving the eye a pink look.  The eyelids tend to be sticky or matted upon waking and a watery discharge is present throughout the day.

Treatment:  Generally no treatment is required but antibiotic drops are sometimes given to prevent secondary bacterial conjunctivitis.

2.  Bacterial Conjunctivitis

Bacterial in origin.  Less contagious than viral forms, but still can be readily spread especially among children who touch and rub their eyes often.  Redness and irritation tend to be more severe producing an eye that is stuck closed upon waking and a mucous discharge throughout the day.

Treatment:  Antibiotic drops.

3.  Allergic Conjunctivitis.

Allergic in nature.  Not contagious.  The trademark symptom is itching, itching, and more itching.  Swelling and redness is generally evident in the eye or lid.  Discharge can be whitish mucous or watery in nature.

Treatment:  Responds to allergy intervention.

Naturally Improve Vision & Go Outside

Childhood sunlight exposure may influence the development of myopia and need for eyeglasses.

Myopia or nearsightedness is a common vision disorder affecting nearly 25% of the US population.  It is created when light focuses in front of the retina which is the light gathering layer that lines the back surface of the eye.

Australian researches looked at children of Chinese origin living in Singapore and Sydney and matched them for age and parental myopia and found the Singaporean children had rates of myopia ten times higher than children in Sydney.  Sydney children actually spent more time in near activities, reading twice as many books per week as the children in Singapore.  The key difference between the two cities appeared to be the amount of time spent outside, with Sydney children out about four times as much as the children in Singapore.

Speculation as to how sunlight exposure may affect myopia development centers around two theories:

Increased lighting decreases pupil size and lessens retinal blur by increasing depth of field.

Sunlight exposure increases dopamine which is known to inhibit eye growth.
