Care for Your Scary Red Eye

At some point, you might be the victim of one of these scenarios: You rub your eye really hard, or you walk into something, or you just wake up with a red, painful, swollen eye. However it happened, your eye is red, you’re possibly in pain, and you’re worried.

What do you do next?

Going to the Emergency Room is probably not your best bet.

Your first reaction should be to go see the eye doctor.

There are many causes for a red eye, especially a non-painful red eye. Most are relatively benign and may resolve on their own, even without treatment.

Case in point: Everyone fears the dreaded “pink eye,” which is really just a colloquial term for conjunctivitis, an inflammation or infection of the clear translucent layer (conjunctiva) overlying the white part (sclera) of our eye. Most cases are viral, which is kind of like having a cold in your eye (and we all know there is no cure for the common cold).

Going to the ER likely means you’re going to be prescribed antibiotic drops, which DO NOT […]

Macular Degeneration + Cataract Surgery

We are frequently asked if it’s wise to have cataract surgery if you have Macular Degeneration.

Let’s start with some background.

  1. Cataracts and Age-related Macular Degeneration (AMD) are both leading causes of visual impairment in the elderly population.
  2. Cataracts develop when the normal clear lens gets cloudy with age. This is correctable with cataract surgery, which involves replacing the cloudy lens with a clear, artificial lens.
  3. While cataracts affect the front part of the eye, AMD causes damage to the retina, which is the inner back lining of the eye.

There have been concerns about cataract surgery causing progression of AMD. It has been thought that there was an inflammatory component to AMD and the normal inflammatory response after cataract surgery may lead to AMD progression.

But studies have looked at patients who underwent cataract surgery compared to patients who didn't have cataract surgery and the progression of AMD was not significantly different between the two groups. However, those patients with AMD who underwent cataract surgery had a significant improvement in vision.

AMD patients can further be characterized as […]

Your Makeup Might Be Making Your Eyes Feel Worse

Dry Eye Disease affects more than 5 million people in the United States, with 3.3 million being women and most of those being age 50 or over. And as people live longer, dry eye will continue to be a growing problem.

Although treatment options for dry eyes have improved recently, one of the most effective treatments is avoidance of dry eye triggers.

For some, that might mean protecting their eyes from environmental triggers. To do that experts recommend using a humidifier in your home, especially if you have forced hot-air heat; wearing sunglasses when outside to help protect your eyes from the sun and wind that may make your tears evaporate faster; or being sure to direct any fans  – such as the air vents in your car – from blowing directly on your face. For others, it may mean avoiding medications that can cause dry eyes.

There is one other trigger that may need to be avoided that doesn’t get as much notice: the potentially harmful ingredients in cosmetics.

Cosmetics do not need to prove that they are “safe […]

The Dreaded Astigmatism

The word “astigmatism” is used so much in the optometric world that most people have talked about it when discussing their eye health with their doctor.

“Astigmatism” comes from the Greek “a” – meaning “without” – and “stigma” – meaning “a point.” In technical ocular terms, astigmatism means that instead of there being one point of focus in the eye, there are two. In other words, light merges not on a single point, but on two different points.

This is experienced in the real world as blurred, hazy vision, and can sometimes lead to eye strain or headaches if not corrected with either glasses or contact lenses.

Astigmatism is not a disease. In fact, more than 90% of people have some degree of astigmatism.

Astigmatism occurs when the cornea, the clear front surface of the eye like a watch crystal, is not perfectly round. The real-world example we often use to explain astigmatism is the difference between a basketball and a football.

If you cut a basketball in half you get a nice round half of a sphere. That is […]

Contact Lenses Need a Backup Plan

There is an old adage in the eye care industry–Glasses are a necessity, contact lenses are a luxury. Ninety-nine percent of the time this is absolutely true. In the absence of unusual eye disorders or very high prescriptions that don’t allow a person to wear glasses comfortably, contact lenses should only ever be worn if there is a good, sturdy, updated set of prescription glasses available, too. This is due to the fact that there are often emergencies where people cannot wear their contact lenses.

In the 21st century, contact lens technology has gotten to the point where we have drastically cut down on the number of adverse events related to contact lens wear. However, human beings were not meant to wear little pieces of plastic in their eyes. Contact lenses are still considered a foreign body in the eye, and sometimes with foreign bodies, our eyes might feel the need to fight back against the “invader.” As such, issues like red eyes, corneal ulcers, eyelid inflammation, dry eyes, and abnormal blood vessel […]

A Super Common Cause for Your Itchy Eyes

Ocular allergies are among the most common eye conditions to hit people of all ages.

Though typically worse in the seasons of Spring and Summer, some people suffer with allergies all year. This is especially true for people who have allergies to pet dander, mold, dust mites, and other common allergens that tend to linger throughout the year.

The hallmark sign of ocular allergies is itching.

While itching can be a symptom of other eye conditions, the likelihood that there is at least some allergy component to the condition is quite high. This seems to be particularly true when the itching occurs mainly in the inner corner of the eyes. This signals that the condition is allergy-related, whereas itching along the eyelid margin suggests other conditions.

Allergy itching is usually accompanied by redness, tearing, and string-like mucus discharge from the eye. When accompanied by rhinitis, sinusitis, and sneezing, people can truly suffer from their allergies – especially as it relates to the eye.

The good news is there are numerous avenues for relief from this annoying condition.

There […]

An Eye on Screen Time

"It was the best of times, it was the worst of times." These famous words by Charles Dickens are playing out today in the area of technology.

We are living in the best of times when it comes to obtaining knowledge at the push of a button. But smartphones, laptops, video games, tablets, etc., can really increase our daily total screen time.

What are the symptoms of too much screen time for the eye, and how can you combat these symptoms?  Research shows that screen time can adversely affect your eyes, focus, moods, and ability to sleep and relax.

Doctors are also seeing an increase in dry eye syndrome because patients do not blink often enough while they are staring at the screen for a prolonged period of time. The lack of blinking can cause burning or watery eyes, rubbing of the eyes, and frequent headaches.

The key to combatting these symptoms is to consciously blink more, use rewetting eye drops, and take frequent breaks. Make it a priority to practice the 20-20-20 rule. […]

What Might Cause Your Eyes to Change Color

It's pretty common for eye doctors to have older patients come in asking if the white part of their eye, the sclera, has a growth or is turning a gray color.

Usually, the culprit is senile scleral plaque, which is commonly seen in people over the age of 70. It is a benign condition and more commonly seen in women.  This condition is symmetrically found on both sides of the eye and is due to age-related degeneration and calcification of the eye muscle insertion into the eye.  In one study, the size of the senile scleral plaque increased as the person aged and was not associated with any medical conditions.  People are asymptomatic, as the plaques do not affect vision and no treatment is needed.

Another commonly asked question is: Why is the colored part of my eye turning white?  

The colored part of the eye is the iris, which is covered by a clear layer called the cornea.  It is actually the edge of the cornea that attaches to the white part of the eye that […]

ABC’s of Primary Angle Glaucoma

There are several different variations of glaucoma, but in this article we will mainly focus on Primary Open Angle Glaucoma. This means that there is no specific underlying cause for the glaucoma, like inflammation, trauma or a severe cataract. It also means that the drainage angle where fluid is drained from the inside of the eye into the bloodstream is not narrow or closed.

Closed or Narrow Angle Glaucoma, which we won't be discussing today, is treated differently from Open Angle Glaucoma

In the U.S., Primary Open Angle Glaucoma (POAG) is by far the most common type of glaucoma we treat.

Glaucoma is a disease where the optic nerve in the back of the eye deteriorates over time, and that deterioration has a relationship to the Intraocular Pressure (IOP).  Most – but not all – people diagnosed with glaucoma have an elevated IOP.  Some people have fairly normal IOP’s but show the characteristic deterioration in the optic nerve. Regardless of whether or not the pressure was high initially, our primary treatment is to lower the IOP.  We usually […]
