How Is Age-Related Macular Degeneration Diagnosed? Tests Explained

age related macular tests

Learning how eye changes are found is the first step to keeping your sight. Many people worry about age-related macular degeneration in SW Calgary because it affects the center of your vision.

This is the part you use to see sharp details. Since you might not notice any symptoms early on, special tests are the only way to catch it before it hurts your vision. Knowing what to expect makes your eye visit much easier.

What Happens During A Full Eye Exam?

A checkup is more than just reading letters on a wall. When you see an optometrist in SW Calgary, they look deep into the back of your eye.

They are looking for tiny yellow spots called “drusen.” These are often the first signs that the condition is starting.

  • Eye Drops: These widen your pupils so the expert can see inside clearly.
  • Vision Test: You will read a chart to see how well you see far away and close up.
  • Pressure Test: A quick puff of air or a light touch checks the pressure in your eye.
  • Retina Check: Using a bright light to look for any changes in the back of your eye.

How Do Special Tools Find Hidden Problems?

New technology lets us see under the surface of the eye. Using early detection tests for age-related macular degeneration vision loss helps find the two types of this disease: “dry” and “wet.”

These tools can see if your retina is getting thin or if there are tiny, leaking blood vessels that shouldn’t be there.

Simple Guide To Eye Tests

This table explains the different tests used to check your eye health.

Test Name What it Does What it’s Like
Amsler Grid Checks for wavy lines Looking at a paper with straight lines
OCT Scan Takes a 3D picture A quick scan using light waves
Angiography Checks blood flow Uses a safe dye to show leaks
Visual Field Checks side vision Clicking a button when you see lights
Photo Shows the back of the eye A high-tech camera takes a picture

Why Is A Simple Grid So Helpful?

One of the best ways to track your sight is with the Amsler Grid. If you are looking for information on age-related macular degeneration near you, this grid is a great tool. You look at a page of straight lines.

If the lines look wavy, blurry, or have a hole in them, it is a big warning sign. This helps people who already have the “dry” form watch out for it turning into the “wet” form, which is more serious.

Using High-Tech Pictures For Your Care

A machine called an OCT has changed how we treat age-related macular degeneration in SW Calgary for our patients.

It works like a camera that sees through the layers of the eye. It is fast, does not hurt, and never even touches your eye.

By looking at these pictures over time, it is easy to see if your eyes are staying healthy or if you need a different treatment.

Things That Increase Your Risk

  • Getting Older: Most people are over 60 when this starts.
  • Family History: If your parents had it, you should get checked more often.
  • Smoking: This is very bad for the health of your eyes.
  • Health Issues: High blood pressure can affect how your eyes work.

Getting ready for your visit

When you go to an optometry clinic near you, bring a list of any changes you have noticed. Maybe words look fuzzy when you read, or colors don’t look as bright as they used to.

You should also bring your sunglasses. Your eyes will be very sensitive to light if the team uses drops to widen your pupils during the exam.

FAQs

+ Do the tests hurt?
None of these tests is painful. The eye drops might sting for a few seconds, but that's it. Most tests just involve looking into a light or at a camera while a picture is taken.
+ How often should I get checked?
If you are over 50, you should have a full exam once a year. If you already have eye changes, we might want to see you every few months to make sure everything stays stable.
+ What is the difference between dry and wet forms?
The dry form is more common and moves slowly. The wet form happens when blood vessels leak fluid into the eye. It is more serious and needs fast treatment to save your sight.
+ Can I check my own eyes at home?
Yes! Using the Amsler Grid every day is a great way to monitor your eyes. If you ever see a change or a wavy line, call us right away instead of waiting for your next visit.

Supporting Ocular Surface Healing and Comfort

The membrane contains natural growth factors and anti-inflammatory properties. When placed over the cornea, it acts as a protective layer that supports healing and may help reduce inflammation.

Potential Benefits

  • Supports Healing: Helps promote natural healing of the eye’s surface.
  • Reduces Inflammation: Its natural properties may help calm inflammation.
  • Improves Comfort: May help relieve discomfort related to dry eye.
  • Supports Recovery: Helps support the healing of the ocular surface.

Who May Benefit?

Amniotic Membrane Therapy may be suitable for people with moderate to severe dry eye, particularly when conventional treatments have not provided enough relief. An eye care professional can assess your eyes and determine if this treatment is appropriate.

How Does It Work?

The amniotic membrane is the innermost layer of the placenta and contains growth factors and anti-inflammatory properties. During treatment, a specially prepared membrane is placed over the eye’s surface to act as a biological covering and support healing.

What to Expect

Before treatment, your optometrist will examine your eyes and determine whether Amniotic Membrane Therapy is suitable for you.

  • Before Treatment: The eye is numbed with topical anesthetic drops, and the area is prepared.
  • Membrane Placement: The preserved and sterilized membrane is placed over the cornea.
  • After Placement: A special contact lens may be used to hold the membrane in place.
  • Post-Treatment Care: Antibiotic or anti-inflammatory eye drops may be prescribed when needed.
  • Follow-Up: Regular visits help monitor healing and the membrane’s absorption or integration.
Some patients may experience mild discomfort, a foreign body sensation, or temporary blurred vision after treatment. Improvement in symptoms may take anywhere from a few days to several weeks, depending on the individual.

Understanding Dry Eye and Your Treatment Options

Dry eye can develop for several reasons, and understanding the underlying cause is an important part of managing symptoms. Our team can assess your eyes and help develop a management plan based on your individual needs.

Common Symptoms of Dry Eye

Dry eye can affect both eyes and may cause different symptoms, including:

  • Stinging or Burning – A burning, stinging, or gritty feeling in the eyes.
  • Eye Redness – Red or irritated eyes.
  • Light Sensitivity – Increased sensitivity to light.
  • Excessive Watering – Eyes that water more than usual.
  • Blurred Vision or Eye Fatigue – Blurry vision or tired, strained eyes.
  • Foreign Body Sensation – A feeling that something is in your eye.

What Causes Dry Eye?

A healthy tear film has several components that work together to keep the surface of the eye comfortable and protected. Dry eye can occur when tear production decreases or when tears evaporate too quickly.

Several factors may contribute to dry eye, including:

  • Aging
  • Allergies
  • Hormonal changes
  • Eyelid problems
  • Gland dysfunction
  • Certain health conditions
  • Living in a dry climate
  • Extended screen time

One common factor is blockage of the Meibomian glands, which produce the lipid layer of the tear film. When these glands are not functioning properly, tear evaporation can increase and contribute to dry eye symptoms.

A Personalized Approach to Dry Eye Management

Managing dry eye involves more than simply using eye drops. Our team can help develop a personalized plan that may include targeted in-office treatments, nutritional guidance, and home care based on your needs. 

Home care may include:

  • Warm Compresses: Used as part of a regular eye-care routine.
  • Lid Hygiene: Keeping the eyelids and surrounding area clean.
  • Artificial Tears: May be recommended to help manage dryness and discomfort.

In-Office Treatment Options

For patients with more severe dry eye symptoms, targeted in-office treatments may be considered. Available options include:

  • Radiofrequency
  • Intense Pulsed Light Therapy (IPL)
  • LipiFlow Therapy

These treatments may be used as part of dry eye management for symptoms such as burning, itching, redness, and irritation. The appropriate approach depends on the underlying factors contributing to your symptoms.

Managing Your Dry Eye Symptoms

Dry eye can have several contributing factors, so treatment is not the same for everyone. A thorough assessment can help identify factors affecting your tear film and determine which management options may be appropriate.

If you are experiencing persistent dryness, irritation, redness, light sensitivity, or other symptoms, speak with our eye care team about your dry eye management options.

Deep Cleansing for Healthier Eyelids and Lashes

ZEST (Zocular Eyelid System Treatment) is an in-office eyelid cleaning and debridement treatment developed by Zocular®. It is designed to clean the eyelids and lashes while helping address concerns associated with dry eye, blepharitis, and demodex.

The treatment uses a natural, okra-based gel to remove oil, debris, and residue from the eyelid margins and lashes. By improving eyelid hygiene, ZEST can help reduce the buildup that may contribute to irritation and inflammation around the eyes.

What Is ZEST?

ZEST works like a deep cleansing treatment for the eyelids and lashes. During the procedure, the okra-based gel is applied along the eyelid margins and lashes using a cotton swab. The gel is gently worked into a lather using circular motions before being rinsed away with saline solution.
The gel contains a refined extract of okra, an edible green seed pod. According to the provided product information, okra helps lift and clear oil, debris, and residue while being gentle around the eye area.

How Can ZEST Help?

Keeping the eyelids, eyelid margins, and lashes clean is an important part of eye hygiene. Buildup along the eyelid edges can contribute to symptoms such as itching, burning, gritty sensations, redness, and irritation.

ZEST is designed to address this buildup through thorough cleansing and debridement.

  • Removes Debris: Helps clear dirt, oil, and residue from the eyelid margins and lashes.
  • Supports Eyelid Hygiene: Provides a deeper cleansing treatment than routine eyelid cleaning.
    Addresses Demodex: The treatment is designed to help remove demodex mites and associated debris.
  • Helps Reduce Inflammation: Cleansing the eyelid area may help address buildup associated with irritation and inflammation.
  • Supports Dry Eye Care: ZEST may help relieve symptoms associated with dry eye and poor eyelid hygiene.

ZEST for Dry Eye, Blepharitis, and Demodex

Dry eye and blepharitis can be associated with inadequate eyelid hygiene. Debris along the eyelid margins can enter the tear film with blinking, potentially contributing to redness and irritation.

Demodex mites can also be present in the hair follicles around the eyelashes. According to the provided information, they may contribute to inflammation and dry eye symptoms by blocking the oil glands at the base of the eyelashes.

ZEST provides targeted cleansing of the eyelid margins and lashes to help remove this buildup and address demodex-related concerns.

A Simple In-Office Treatment

The ZEST procedure is performed in the office and involves applying the cleansing gel to the eyelid margins and lashes, working it into a lather, and then rinsing the area with saline solution. The treatment is designed to provide thorough eyelid and lash cleansing without requiring a lengthy procedure.

Is ZEST Right for You?

ZEST may be considered for patients experiencing symptoms associated with dry eye, blepharitis, demodex, or eyelid debris. An eye care professional can assess your symptoms and determine whether ZEST is appropriate for your eye care needs.
