Vitreous Detachment

What is the Vitreous?

The vitreous is similar to a clear viscous gel and it fills the back part of the eye and helps to maintain the shape of the eye.  It fills the space behind the lens in our eye to our retina.   The vitreous has fibers that attach to our retina.  It is normal for the vitreous to shrink and liquefy with age.   It often eventually separates from the back of the eye.  This is called a vitreous detachment.

What is Vitreous Degeneration?Vitreous detachment | Alaina Kronenberg MD

Vitreous degeneration is when the vitreous liquefies and shrinks.  The fibers that attached to the retina can separate from the retina with time.  This is caused a vitreous detachment.

It is normal for this to occur with age.  If you have had previous cataract surgery, trauma or high myopia the vitreous can often degenerate faster that it otherwise would.

What is a Vitreous Detachment?

A vitreous detachment is when the vitreous pulls away from the retina.  This is very common especially after age 80.  You may experience new floaters in your vision and you may see flashes or lightening streaks of light in your vision when this is occurring.  This can be very scary and worrisome for you!

It is normal for you to notice floaters of different shapes and sizes.  You may see the floater as more circular or more linear in shape.  The floaters may move around in your vision and sometimes can interfere with your vision.  Most people get used to the floaters with time and they often become less bothersome and not as noticeable.

What Should I Do if I Notice New Floaters?

If you notice new floaters or flashes of light, it is important that you have a dilated examination.   It is important that Dr. Stanley Grandon, Dr. Cindy Wang or I ensure that there is no retinal tear or retinal detachment.   This would need immediate treatment to ensure no vision loss occurs.   It is important that you call our office immediately if you notice any new floaters or flashes.

Itchy, Red Eyes

Itchy, Red Eyes

Allergy season is quickly approaching!  Do you suffer from spring allergies? Are your eyes usually itching and red?  Are they feeling uncomfortable?  What is the cause of these symptoms and can anything be done?  Itching and redness can be very frustrating and uncomfortable.  You may be suffering from eye allergies.  Sometimes it is nearly impossible to avoid being exposed to the things we are allergic to.

You may have tried over the counter remedies to see if they can improve your symptoms.  If the over the counter treatments are not providing proper relief, it is important to have a comprehensive eye examination to determine the cause of your symptoms.  Your condition may or may not be ocular allergies.  You want to consider when your symptoms occur most.  Are they worse in the morning or evening?  Are they worse during a particular season of the year?

Diagnosiseye allergies | Alaina Kronenberg MD

Dr. Stanley Grandon, Dr. Cindy Wang and I will take a complete history and perform an eye examination.  It is important to distinguish if your eyeballs feel itchy or your eyelids are bothering you more.

Itchy eyes are often a symptoms of ocular allergies.  You may also complain of watery eyes, stringy mucous discharge, eyelid swelling, and irritation.  Ocular allergies are when the eyes are exposed to allergens.  Different patients can react to different allergens.   Your symptoms are often due to release of histamine and mast cells and symptoms will often vary during different seasons depending on what the allergen is that is causing your symptoms.

If your symptoms are more affecting your eyelids, you may be suffering from blepharitis instead of eye allergies.  Blepharitis is inflammation of the eyelid margin and the eyelids can become itchy, red and irritated.

If you wear contact lenses sometimes your condition can be related to your contact lenses.  You may have developed a sensitivity to your contact lenses or be wearing them too much.

It is important for your doctor to make the proper diagnosis so we can offer the treatments that will improve your symptoms.

Treatment of Eye Allergies

If you suffer from eye allergies, it is important to try to avoid the allergen if possible.  Ocular allergies are often initially treated with eye drops that are antihistamines and mast cell stabilizers.  These medications work more effectively if they are used regularly during your allergy season.  If your symptoms are severe, we may add a short course of a mild steroid eye drop also.  Sometimes chilled artificial tears can also help your symptoms.

How Does LASIK surgery work?

What is LASIK?

How does LASIK surgery work?  LASIK stands for Laser Assisted In Situ Keratomileulis.  It is an eye surgery using the VISX laser to reshape the cornea.  The purpose of the eye surgery is to change the surface of the cornea allowing it to refocus light onto the retina so you can see clearly.  You may consider LASIK if you would like to be less dependent on glasses.

Can I Have Lasik?How does Lasik surgery work?

LASIK can treat certain amounts of nearsightedness (myopia), farsightedness (hyperopia) and astigmatism.  There is often a misconception that LASIK cannot treat astigmatism.  Dr. Stanley Grandon and I can perform a comprehensive LASIK evaluation to determine if you are a candidate for LASIK.  We need to make sure your eyes are healthy enough to have the surgery and that your glasses prescription is in the ranges that LASIK can be safely performed.  If you already require reading glasses, we can discuss options with you as well.

How Does Lasik Surgery Work?

The cornea is extremely powerful in focusing light.  It is responsible for 2/3 of the focusing power of the eye. Therefore reshaping the surface has tremendous effects on focusing without the need for glasses.

The laser removes microscopic amounts of tissue on the cornea so that the cornea focuses light onto the retina.  If you are nearsighted (myopic) the cornea will need to be made flatter.  If you are farsighted (hyperopic), the cornea will need to be made steeper, and if you have astigmatism the cornea will need to be made less irregular.

Lasik is a pain free outpatient procedure.  Dr. Stanley Grandon and I will focus the laser onto your eye and perform the procedure in about 5 minutes.  After the procedure, your eye will likely feel scratchy and the vision may be blurry for a few days.  You will need someone to drive you home and then you will be seen in our office the next day.

If you would like to schedule a LASIK evaluation, please call :3135828856

What is a Floater?

 Floaters  are when you see a small clump or cloud moving around in your vision.  You may notice them more when looking at a white background.

Floaters become more common as we age.  They form when the jelly that fills the back of our eye liquefies with age.  Portions of the vitreous often clump together and you notice a floater moving around in the vision.

A floater may present in different shapes and sizes.  For example, you may notice a circle, a line or strand, a clump or a cobweb shape.

Why do we get Floaters?Floaters and Flashes | Eye Surgery Institute | Alaina Kronenberg MD

As we age, the vitreous jelly that fills the back of our eye liquefies.  As the jelly liquefies and shrinks, you may notice new floaters.  The vitreous jelly often pulls away from the back of our eye as we age causing a posterior vitreous detachment (PVD).

Why do we get Flashes?

Flashes are when you see lightning streaks or stars in your vision.  We often see flashes when the vitreous jelly is trying to pull away from the retina.  Traction can occur and this can give the sensation of flashes of light in your vision.  Flashes related to your retina usually last a only a few seconds.  Flashes lasting several minutes can be caused by other problems such as a migraine.

Why Do I Need To Have an Urgent Eye Examination?

New floaters and flashes can possibly be a symptoms of a retinal tear or a retinal detachment.  This can be vision threatening.   As the vitreous gel liquefies and shrinks it pulls away from the retina.

It is possible that your new floaters or flashes could signal a serious ocular problem.  There is no way to tell if you have a retinal tear or retinal detachment without an examination.  It is important to have an urgent dilated eye examination to check for a retinal problem.  It is also important to call if you notice a curtain or window shade in your vision.

I am a runner


I am a runner.  I haven’t always been a runner, but in the last few years I have enjoyed running more and more.  I have found that as I get older, it’s easy to keep in shape and eat the desserts I love if I exercise.  The easiest way to exercise with a busy work schedule is to literally run out the door of my house.  It’s a little tougher for me in the wintertime as I’m confined to the treadmill or running in the cold and often on snow and marathon

Running fits just fine into my family life as I can go early in the morning and it doesn’t interfere with my kid’s hectic schedules.  I guess you can say that I’m addicted now, but there are plenty worse things to be addicted to.  I love it and I have made new friends running.  I enjoy spending time with these friends on our early morning runs.

Boston Marathon

Without realizing it, I continued to get stronger and faster.  Over the years I had run many half marathons.  I finally decided to run my first marathon 3 years ago and I since have qualified for the Boston marathon.

Running a marathon is a much about mental toughness as it is about physical capabilities.  No matter how prepared your body is for the race, you need to keep your brain from wanting to quit when you start to hurt.

The Boston marathon is the premier marathon and requires all runners to qualify to be able to participate.  Some people try all their lives to get in.  Qualifying for the Boston marathon is a source of personal pride.  I have run the race in 2015 and 2016.The energy there is intoxicating.  Everyone is so happy to be there and is so open to sharing their experiences.  The personal stories are incredible.
