Macular Degeneration

Age-related macular degeneration (ARMD) is a leading cause of vision loss among people age 50 and older.

The macular provides sharp central vision. It is located in the back of the eye and it is the most sensitive part of the retina. The retina converts light into neural signals, and then send these signals to our brain for visual recognition. When the macula is damaged, your central vision appears distorted and blurry. This defect causes problems with reading, driving, watching TV and recognizing faces. You may also find the need for brighter light when reading, cooking, and performing daily activities. Some people experience impaired depth perception.

According to Dr. Dhaliwal, “...risk factors include age, smoking, race and family genetics.” By making healthy life choices along with regular eye exams, Dr. Dhaliwal may be able to slow down progression of ARMD.

Five things that can be done to reduce the risk of developing macular degeneration include:

  1. Do not smoke
  2. Eat health foods with a diet rich in green, leafy vegetables
  3. Eat fish high in omega-3 fatty acids
  4. Maintain normal blood pressure, blood sugar, and cholesterol levels
  5. Exercise and wear sunglasses to protect your eyes from UV light

At Chicagoland Eye Consultants, a comprehensive dilated eye exam along with special testing can detect ARMD. We encourage you to ask our eye care professional, Dr. Dhaliwal, questions to help you better understand your diagnosis and treatment.


Glaucoma is the second top cause of preventable blindness globally, yet half of the people suffering from this disorder are unaware.

This disorder is often referred as “the silent thief of vision” with long-term effects on our eyes. The good news is that vision loss can be prevented when glaucoma is diagnosed and treated early.

We asked our experienced ophthalmologist, Dr. Dhaliwal to explain what glaucoma is. Dr. Dhaliwal explains, “Glaucoma is a disorder where damage occurs to the optic nerve, primarily due to pressure to the optic nerve. It is similar to blood pressure, in that you cannot feel the pressure. By the time you have noticeable loss of vision, it might be too late” Dr. Dhaliwal explains.

Who’s at risk? According to Dr. Dhaliwal, “Family history and age are important risk factors for glaucoma. Certain medical conditions such as diabetes, cardiovascular disease and hypertension play a role as well.”

Since this eye disorder does not come with warning signs especially in its earliest phases, it is critical that Dr. Dhaliwal performs a comprehensive eye exam. At Chicagoland Eye Consultants, we offer a wide range of treatments to keep intraocular pressure at a healthy level.

If you have concerns about your vision or would like to discuss glaucoma treatment options, contact us. You can schedule a comprehensive eye health exam at our Chicago or Elgin office with Dr. Dhaliwal. Scheduling a dilated eye exam at Chicagoland Eye Consultants is easy; call us at (773) 775-9755.

Back to School Eye Exam

Summer in Chicago always goes by so fast and the start of the new school year is upon us quickly.  There are many things on our checklist when preparing for the kids to go back to school, but one thing that is often overlooked is an eye exam.  Kids of all ages can have vision problems that lead to poor performance in school. 

We find that kids don’t complain or don’t know that they are having a problem that is related to their vision.  It could be that their vision is blurry or uncomfortable and they need glasses.  But, many times, it is not that simple.  We also evaluate the binocular vision system.  Poor binocular coordination (Convergence Insufficiency, Divergence Insufficiency, and Ocular Motor Dysfunction) can lead to headaches, eyestrain, skipping words/lines when reading or poor attention when reading.  These symptoms are sometimes misdiagnosed as a learning disorder, poor reading skills or ADHD and if the child had and eye exam they would have been back on track quickly.

In our pediatric clinic at Chicagoland Eye Consultants, we recommend that all kids are seen for an eye exam by 3-4 years of age.  The State of Illinois requires that kids have a comprehensive eye exam before entering Kindergarten.  Then, beyond that, it is a good idea to have your kids seen each year before school starts.

Make sure your kid’s eyes are ready to start the school year and call us today for a back to school eye exam.

What does it mean to have astigmatism?

So you’re one of the many people with astigmatism, but are you one of the few who actually knows what that means? Astigmatism is one of, if not the most misunderstood eye problem around. For starters it is commonly mistaken for a disease or a vision health problem when in actuality it is simply a problem with how the eye focuses light.

Astigmatism is caused by an irregular shaped cornea, the clear, round dome covering the eye’s iris and pupil. Or it may be caused by the curvature of the lens inside the eye. Whichever the cause it ends up preventing light from focusing properly on the retina which is called a refractive error. When the cornea has an irregular shape, it is called corneal astigmatism. When the shape of the lens is distorted, you have lenticular astigmatism. As a result of either type, your vision for both near and far objects can appear blurry or distorted. Other symptoms include eyestrain, headaches and eye discomfort.

Astigmatism is very common. In most cases, people with astigmatism are born with this condition. The reason why corneal shape differs from person to person is still unknown, but the likelihood of developing astigmatism is inherited. On occasion astigmatism can develop after an eye disease, injury or surgery.

Diagnosing astigmatism is easily done by your eye doctor with a comprehensive eye examination. There are a few test the doctor may choose to perform to measure how the eyes focus light and may determine the power of any optical lenses needed to compensate for reduced vision. This examination may include:

Visual acuity—As part of the testing, you'll be asked to read letters on a distance chart. This test measures visual acuity, which is written as a fraction such as 20/40. The top number is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at forty feet in order to see it clearly. Normal distance visual acuity is 20/20.
Keratometry- A keratometer is the primary instrument used to measure the curvature of the cornea. By focusing a circle of light on the cornea and measuring its reflection, it is possible to determine the exact curvature of the cornea's surface. This measurement is particularly critical in determining the proper fit for contact lenses. A more sophisticated procedure called corneal topography may be performed in some cases to provide even more detail of the shape of the cornea.
