Four Dry Eye Symptoms

Dry eye syndrome (DES) is a common disorder of the tear film.  The syndrome affects a significant percentage of the population, especially those older than 40 years of age. It is more common in women than in men.  DES results from one of the following:

  • Decreased tear production
  • Excessive tear evaporation
  • An abnormality in the production of mucus or lipids normally found in the tear layer

Other causes of dry eye syndrome can include antihistamines, antidepressants, LASIK surgery and excessive wearing of contact lenses.

Symptoms of dry eye syndrome include:

  • feelings of dryness, grittiness or soreness, which might get worse as the day progresses
  • redness of the eyes
  • watering eyes, particularly when exposed to […]

Light Flashes in Eyes

Many conditions can cause photopsia – flashes of light in the eye. Light flashes in eyes can be harmless or they can be an indicator of a serious problem that needs immediate treatment. It is important to be evaluated by an eye doctor for an accurate diagnosis of the cause of light flashes in your eyes. Seek immediate medical attention if your flashes occur with vision loss or small specks that appear to float or dart from side to side in your vision. Below we will review some causes of light flashes in eyes.

Migraines – Migraines are severe recurrent headaches that last from a few hours to several days, […]

The Effects of High Blood Pressure on Your Eyes

High blood pressure can be very harmful to the body, causing heart and kidney problems among others. If untreated, high blood pressure can also affect your eyesight and lead to eye disease. High blood pressure can damage blood vessels in the retina. The retina is the layer of tissue at the back part of the eye. It changes light and images that enter the eye into nerve signals that are sent to the brain. The higher the blood pressure and the longer it has been high, the more severe the damage is likely to be.

The most common eye disease caused by high blood pressure is known as hypertensive retinopathy.

Other problems […]

Black Floating Spots in Vision

If you notice small black floating spots drifting across your field of vision – known as eye floaters – you might be concerned. Most of the time, these tiny specks and squiggly strands are harmless, but they can occasionally be cause for concern. Here’s what you need to know about black floating spots in your vision.

Usually, eye floaters are nothing more than bits of debris that are left over from age-related shrinkage of the vitreous – the jelly-like fluid inside the eyeball. They become more common as the vitreous ages.

Eye floaters can appear as black or gray dots, lines, cobwebs or blobs. Because the floaters are inside the fluid […]

Winter Eye Protection

With winter just around the corner, it’s important to know how to protect your eyes during this season. When the days are cloudy and cold, sunglasses are probably the last thing on your mind. But winter eye protection can prevent painful temporary conditions and permanent eye damage.

Did you know your eyes can get sunburned in the winter? Snow and ice reflect 80% of the sun’s ultraviolet (UV) rays. UV exposure can cause a painful condition called photokeratitis (snow blindness.) Whether you’re skiing, snowboarding or working outdoors, UV rays strike from every angle, even on cloudy days.

Sunglasses that block 100% of UV rays protect your eyes from glare. Wraparound sunglass […]

Macular Holes and Cataracts

Degenerative conditions that affect the retina, the part of the eye responsible for forming images, can pose a serious threat to a person’s vision. In Medford, the doctors at Medical Eye Center provide exceptional treatment for retinal conditions such as macular holes and cataracts, among others.

Macular Holes: A macular hole is a small break in the macula which is located in the center of the retina. The macula is the part of the retina responsible for central vision so anything affecting the macula will likely affect visual acuity and quality. Fluid that is inside the eye may leak through the hole, causing blurred and distorted vision. Some macular holes heal themselves, […]

Vision Exam Instruments

There are many eye exam instruments that the doctors at Medical Eye Center in Medford uses to evaluate the whole vision system and diagnose eye health. Below are just a few of the primary eye exam instruments that are currently in use.

Ophthalmoscope: There are two kinds of ophthalmoscopes: the smaller hand-help monocular direct (MO) and the larger binocular indirect (BIO). The MO is used to examine the back of the eye; that is, the optic nerve, blood vessels, the macula and the fundus- the general term for the back of the eye. The MO allows for a somewhat magnified view with limited viewing field.

The BIO is an instrument which […]
