What Is Causing My 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 becomes […]

What to Know About Dropless Cataract Surgery

After cataract surgery, there are two main issues we try to control: preventing infection and controlling inflammation.  Traditionally, we prescribed antibiotic eye drops to prevent infection, as well as steroid eye drops to control post-operative inflammation. But eye drops can be hard for some patients to put into their eyes. Now we have some alternatives to using drops after surgery.   

There are some antibiotic solutions we can place inside the eye at the end of the cataract surgery that have been shown in most studies to do as good or better a job preventing infection as using antibiotic eye drops before and after surgery.

The FDA approved steroid delivery methods to reduce post-operative inflammation that have the potential to eliminate post-op steroid eye drops in most (but not all) patients who are undergoing cataract surgery. Two of these products are called Dexycu and Dextenza.

Dexycu is a white bolus of steroid medication that is injected inside the eye after cataract surgery. It will not be visible in most patients because it is injected behind the iris, or the […]

The Solution for Your Contact Lens Care

Oftentimes, contact lens wearers will skimp on their lens care because some of the solutions are costly and it seems like a good way to save some hard-earned cash. But this is not a good idea.

Cutting corners can result in infections or irritations, and after one or two copays to your eye doctor's office you probably will have spent more than what you saved in a year by cutting corners–plus you have to deal with your discomfort and inability to wear your contact lenses while you are being treated.

The reasons you clean your contacts is to give increased lens comfort, prolong lens oxygen permeability, and to protect your eyes from infection. The reason you have to disinfect your contact lenses is – as nasty as it may sound – that your eyeball and eyelids are covered in essential bacteria that are kept in check by your body’s immune system. When you remove your contact lens at night it is covered in these essential bacteria. If you don't kill them overnight this will allow the […]

6 Reasons to Wear Great Sunglasses

Sunglasses are more than just a fashion statement – they’re important protection from the hazards of UV light.

If you wear sunglasses mostly for fashion that’s great–just make sure the lenses block UVA and UVB rays.

And if you don’t wear sunglasses, it’s time to start.

Here are your top 6 reasons for wearing sunglasses:

#1–Preventing Skin Cancer

One huge way that sunglasses provide a medical benefit is in the prevention of skin cancer on your eyelids. UV light exposure from the sun is one of the strongest risk factors for the development of skin cancers.  

Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon.

About 90 percent of non-melanoma skin cancers are associated with exposure to ultraviolet (UV) radiation from the sun.

Your eyelids, especially the lower eyelids, are also susceptible to UV light and they do develop skin cancers somewhat frequently.

Many people who now regularly apply sunscreen to help protect them from UV light often don’t get that sunscreen up to the edge of […]

7 Tips for Your Best Eye Exam

The eye holds a unique place in medicine. Your eye doctor can see almost every part of your eye from an exterior view. Other than your skin, almost every other part of your body cannot be fully examined without either entering the body (with a scope) or scanning your body with an imaging device (such as a CAT scan, MRI, or ultrasound).

This gives your eye doctor the ability to find many eye problems just by looking in your eye. Even though that makes diagnosing most problems more straightforward than in other medical specialties, there are still many things you can do to get the most out of your eye exams. Here are the top 7 things you can do to get as much as possible out of your exam.

1) Bring your corrective eyewear with you. Have glasses? Bring them. Have separate pairs for distance and reading? Bring them both. Have contacts? Bring them with you and not just the lenses themselves but the lenses prescription, which is on the box they came in. What […]

How to Deal with 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 […]

Why You Shouldn’t Try to Get By with Just Contact Lenses

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 growth can result […]

The Lowdown on Low Vision

Recent Census Bureau data shows a population of approximately 71 million baby boomers (the generation born from 1946-1964). What does that have to do with low vision you may ask? Approximately 40 million people worldwide have some sort of blindness, and aging increases the incidence of macular degeneration and other vision impairment that qualifies them as “low vision” persons.

Low vision is a condition of the eye in which the vision falls below 20/70 in the better seeing eye. It impairs the recipients, rendering them unable to perform daily tasks that others take for granted. With this rising aging population, the awareness of low vision therapy, diagnosis, and treatments are more widely available.

Low vision treatment can help people recover from decreased visual function due to retinal disease, brain injury, neurological damage, and other causes.

It is not only the elderly population that is affected–approximately 20% of low vision patients are children under the age of 18. Childhood genetic disorders of the eye such as retinitis pigmentosa, albinism, Bests disease, ROP, rod/cone disorders, and glaucoma are […]

Why Dilation Reversal Drops Are Not Currently an Option

Getting your eyes dilated can be inconvenient – dilation makes your eyes light sensitive, which can make it difficult to read books or use phones and computers for a few 4 hours.

So wouldn’t it be great to have another drop to reverse the effects of dilation?

On Dec. 31, 1990, dapiprazole, under the trade name Rev-Eyes, was approved by the FDA and thought to be the answer to all the post-dilation problems. It was marketed for treatment of medically-induced dilation by stimulating pupillary constriction and restoration of accommodative function for reading.

In clinical practice, dapiprazole took between one to two hours to return pupils to pre-dilation size.

Side effects such as stinging upon instillation, conjunctival hyperemia (redness of eye), headache, and a few instances of ptosis (lid drooping), with a possible additional dollar cost to patients, seemed to lessen dapiprazole’s overall clinical benefit.

Reading ability returned in approximately 43 minutes with dapiprazole vs 66 minutes without the drop (Optom Vis Sci 1994 May; 71(5):319-22). The main complaint that people had after using dapiprazole was the […]
