Retina Scans

           Optical Coherence Tomography is a non-invasive imaging test that may be performed as a standard part of your regular, comprehensive exams, or you may be able to request this test as an addition to your usual exam.

Optical Coherence Tomography uses light waves to take cross-section images of your retina, which is the area of light-sensitive cells at the back of your eye that is responsible for receiving light and transmitting it into messages that are sent up to the brain. The technology behind OCT enables your eye doctor to see each of the different layers that make up the retina. By being able to see these and measure them, they can obtain a much clearer picture of the overall health and condition of your eyes.

Why are Optical Coherence Tomography scans important?


When you choose to have an OCT scan at fairly regular intervals, such as during your normal comprehensive eye exams, your eye doctor can compare newer results to previous ones. This helps them to build up a picture of the health of your eyes, and spot any changes which may be concerning, early, before they cause symptoms or have a permanent effect on your vision. 

Anyone can have an OCT scan, but they are particularly recommended for patients over the age of 25 who are concerned about the health of their eyes, or who are at risk of or already have diabetes, glaucoma or a family history of eye disease. This is because they can be used to spot the early signs of a range of eye diseases, including glaucoma, diabetic retinopathy, macular degeneration, disorders of the optic nerve and more – even before you realize that you are affected.


            A tonometer refers to the equipment that is used in tonometry – a test that measures the pressure inside your eyes, also known as intraocular pressure or IOP for short. Tonometry is rarely performed at your average comprehensive eye exam unless you are at high risk of or have been already diagnosed with glaucoma. Fortunately, tonometry can be used to detect changes in eye pressure before they cause any symptoms, enabling prompt action to be taken before your vision is affected.

About Glaucoma

Glaucoma is a common eye condition that occurs when the optic nerve, which connects the eye to the brain, becomes damaged. It’s normally caused by fluid building up in the front part of the eye, which causes the pressure inside the eyes to build. As the pressure increases, the optic nerve becomes increasingly damaged, and this prevents messages from being transmitted between your eyes and brain effectively. As a result, the patient’s vision becomes compromised. Without treatment, the level of vision loss will continue to increase. Unfortunately, any vision that has been lost as a result of glaucoma cannot be restored.

Most of the time, glaucoma develops very slowly which means that many people don’t realize that they are affected until some damage to their vision has already occurred. However, occasionally glaucoma can develop quickly, and symptoms do occur.

These can include:

  • Red eyes

  • Intense headaches

  • Tenderness around the eyes

  • Eye pain

  • Seeing rings/halos around lights

  • Blurred vision

  • Nausea and vomiting

If you notice any of these symptoms, it’s important that you make an appointment with your eye doctor right away so that you can be assessed. You are likely to have a tonometry test as part of this assessment.

What to expect from tonometry testing

There are various methods of tonometry testing, but many eye doctors use either Goldmann tonometry, which is the conventional technique to measure eye pressure, or electronic tonometry.

Goldmann tonometry testing is carried out using the Goldmann applanation tonometer, which is attached to a slit lamp microscope. This requires anesthetic eye drops to be used which numb your eyes, before a small probe is pressed gently against the eye, indenting the cornea. The pressure that the cornea pushes back onto the tonometer is what is measured to give your IOP reading. Electronic tonometry is where a handheld, mobile device is gently and quickly applied to the cornea to check the pressure, providing an accurate reading. Some eye doctors also offer non-contact tonometry which is where a puff of air is used to flatten the cornea, although this is reported to be less accurate than the Goldmann technique.

Retinal Imaging Testing

           When it comes to maintaining your eye health, regular check-ups and screenings play a crucial role. One such screening method that has revolutionized the field of optometry is retinal imaging testing. This non-invasive procedure allows optometrists to capture detailed images of the retina, providing valuable insights into the overall health of your eyes.


The Importance of Retinal Imaging Testing


By examining the retina, which is the thin layer of tissue at the back of your eye responsible for capturing light and transmitting visual signals to the brain, optometrists can gain valuable insights into your eye health. Retinal imaging testing allows for the early detection of various eye conditions even before noticeable symptoms occur. This early detection is crucial as it enables prompt treatment and intervention, potentially preventing irreversible vision loss.

Advanced Retinal Imaging Technology


Retinal imaging testing has been made possible by the advancements in technology, specifically Optical Coherence Tomography (OCT) and Optos imaging. OCT is a non-invasive imaging technique that uses light waves to capture high-resolution cross-sectional images of the retina. It provides detailed information about the layers of the retina, helping eye doctors identify and monitor various eye conditions.

Optos imaging utilizes ultra-widefield retinal technology to capture a panoramic image of the retina. This technology allows for a more comprehensive view of the retina, including the periphery. Dilating drops are not necessary with Optos, making the process more convenient for patients.

Visual Field

          Visual field testing is an important part of most standard comprehensive eye exams. Also sometimes known as perimetry testing, Visual field testing is a method to measure the entire scope of vision of an individual, including their peripheral/side vision.

The importance of visual field testing

Visual field testing is one of the most effective diagnostic treatments in the detection of glaucoma. This is because when patients are affected by glaucoma, it is usually the peripheral vision that is affected by their condition first. However, it can also be used to detect central or peripheral retinal diseases, eyelid conditions such as drooping, optic nerve damage and conditions that affect the visual pathways from the optic nerve to the area of the brain where this information is processed into vision.

Visual field testing is also an important part of monitoring for people who are considered to be at risk for vision loss from disease and other problems, including those who have been diagnosed with the following:

  • Multiple sclerosis

  • Hyperthyroidism

  • Pituitary gland disorders

  • Central nervous system problems (such as a tumor that may be pressing on the brain)

  • Stroke

  • Diabetes

  • High blood pressure

What to expect from visual field testing

There are a variety of methods that can be used to perform visual field testing, including:

Static automated perimetry. This is where a machine is used to quantify how well the patient is able to detect flashing lights of varying size and brightness in different areas of their visual field, while they concentrate on a central point. The patient responds by pushing a button when they see the light.

Kinetic perimetry. This involves points of light that are fixed in size and intensity and are presented along the patient’s peripheral vision, before being gradually moved inwards to determine their field of vision. 

Visual field testing is non-invasive, painless and doesn’t require patients to have their eyes dilated. The results, which are usually presented in a series of charts, are digital and sent directly to your eye doctor for interpretation. Depending on the outcome of your results, you may be recommended for further diagnostic testing which could include blood tests. If you have been diagnosed with glaucoma, you will probably be recommended to have several visual field tests each year, which will help your eye doctor to monitor the progression of your condition and recommend treatments to slow it.

If you would like more information about visual field testing, or if you have concerns about your peripheral vision, please don’t hesitate to schedule an appointment with our experienced and knowledgeable eyecare team today.

Dry Eye Advanced Diagnostic Testing

          Dry eye is a common ocular condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to discomfort, redness, blurred vision, and even damage to the surface of the eyes. Understanding the causes and symptoms of dry eye is crucial provide early detection and effective treatment.

The Importance of Dry Eye Advanced Diagnostic Testing


Early detection of dry eye is crucial for preventing further progression of the condition and improving patient outcomes. Without proper diagnosis and treatment, dry eye can cause significant discomfort and affect daily activities. Additionally, chronic dry eye can lead to corneal ulcers, infections, and even vision loss. By accurately identifying and addressing dry eye in its early stages, optometrists can provide timely interventions and prevent complications.



Inflammation plays a significant role in dry eye, and identifying the presence of inflammation is crucial for effective treatment. InflammaDry is a diagnostic tool that detects elevated levels of matrix metalloproteinase 9 (MMP-9), an inflammatory marker, in tears. By measuring MMP-9, InflammaDry helps optometrists differentiate between inflammatory and non-inflammatory dry eye. This information is essential for tailoring treatment plans and determining the most appropriate therapies for each patient.
