Peripheral vision is the ability to notice objects, people and movement outside your direct line of sight. Changes to this part of your vision can be difficult to recognise, particularly when they develop gradually and your central vision remains clear. Glaucoma is one possible cause of progressive peripheral vision loss, as damage to the optic nerve can affect the visual field over time. If you notice persistent changes in your peripheral vision, it may be worth seeing a glaucoma specialist in Singapore for a thorough assessment. A visit to a glaucoma specialist clinic in Singapore can help determine whether your symptoms may be related to glaucoma or another underlying eye condition.

What Does Peripheral Vision Loss Feel Like?

Peripheral vision loss may not be obvious at first because the changes can develop gradually. You may still see objects directly in front of you clearly while having more difficulty noticing what is happening to either side. Some people may find themselves bumping into objects, missing people approaching from the side or needing to turn their head more often to see things that were previously within their field of view. 

In some cases, these changes may affect one eye more than the other, making them harder to recognise. Because peripheral vision changes can have different causes, persistent or worsening symptoms should be assessed rather than assumed to be a normal part of ageing.

Why Can Glaucoma Affect Peripheral Vision?

Glaucoma can affect peripheral vision because the condition damages the optic nerve, which carries visual information from the eye to the brain. As optic nerve damage progresses, areas of the visual field may gradually become less sensitive. In many cases, peripheral vision is affected before central vision, so a person may continue reading, using a phone or recognising faces while changes are already developing at the edges of their vision. 

Elevated eye pressure is an important risk factor, although glaucoma can also occur when eye pressure is within the usual range. This is why eye pressure alone cannot determine whether someone has glaucoma. A comprehensive assessment is needed to evaluate the optic nerve, visual field and other signs of eye health.

When Should You See A Glaucoma Specialist Singapore?

Persistent or worsening changes in peripheral vision should not be ignored, particularly when they begin to affect your daily activities. It may be appropriate to arrange an eye assessment if you notice:

• Bumping Into Objects: Frequently knocking into furniture or objects that are outside your direct line of sight.
• Missing Movement From The Side: Not noticing people, vehicles or other movement approaching from your peripheral vision.
• Needing To Turn Your Head More Often: Finding that you need to move your head to see objects that you previously noticed without doing so.
• Changes In One Or Both Eyes: Noticing a difference in your peripheral vision between your eyes or changes affecting both eyes.
• Progressive Visual Changes: Finding that your peripheral vision appears to be narrowing or becoming less clear over time.

A glaucoma specialist in Singapore can assess your eyes to determine whether glaucoma or another condition may be contributing to these changes. Sudden or severe vision changes should be assessed promptly rather than assumed to be related to glaucoma.

How Is Peripheral Vision Loss Assessed?

When you see a glaucoma specialist in Singapore for peripheral vision changes, the assessment may involve several tests to understand how well you see and whether there are signs of optic nerve damage. Depending on your symptoms and eye health, your evaluation may include:

• Visual Field Test: Measures how well you can see objects in different areas of your visual field, including your peripheral vision.
• Eye Pressure Measurement: Checks the pressure inside your eyes, which is an important factor when assessing glaucoma risk.
• Optic Nerve Examination: Allows the specialist to look for changes that may indicate optic nerve damage.
• OCT Scan: Produces detailed images of structures at the back of the eye and may help identify changes associated with glaucoma.
• Additional Eye Tests: Other assessments may be recommended depending on your medical history, symptoms and examination findings.

These tests are considered together rather than relying on a single measurement. This helps determine whether peripheral vision changes may be related to glaucoma or another eye condition and whether further monitoring or treatment may be appropriate.

What Happens If Glaucoma Is Diagnosed?

The next step is to determine the type and extent of the condition and how it is affecting your optic nerve and visual field. Treatment is generally focused on reducing the risk of further optic nerve damage and preserving the vision you still have. Depending on your individual circumstances, a glaucoma specialist may consider:

• Prescription Eye Drops: Medicated eye drops may be used to lower eye pressure and help manage glaucoma.
• Laser Treatment: Certain types of glaucoma may be managed with laser procedures to improve fluid drainage or reduce eye pressure.
• Surgery: If eye pressure remains difficult to control with other approaches, surgery may be considered.
• Regular Monitoring: Follow-up appointments and repeat tests can help track eye pressure, optic nerve health and changes in the visual field.

Treatment does not usually restore vision that has already been lost from glaucoma. However, appropriate management and regular follow-up can help monitor the condition and reduce the risk of further vision loss.

Do Not Wait For Peripheral Vision Loss To Progress

Peripheral vision changes can be subtle, particularly when central vision remains unaffected. However, progressive loss of peripheral vision may be associated with glaucoma or other eye conditions that require assessment. If you notice increasing difficulty seeing objects or movement from the side, it is worth arranging an eye examination rather than waiting for the changes to become more noticeable. 

A glaucoma specialist in Singapore can assess your visual field, eye pressure and optic nerve health to determine whether further investigation or treatment is appropriate. Early assessment can also provide a clearer understanding of your eye health and help guide appropriate follow-up care. For enquiries or appointments, contact our eye clinic at:
