Diabetes and Eye Health: Why Regular Retinal Screening Matters by Dr Rupal Morjaria

Diabetes can affect many parts of the body over time, including the eyes.

One of the most important aspects of diabetic eye care is understanding that significant retinal changes can develop long before vision is noticeably affected.

This is one of the reasons why regular retinal screening is so important.

In my practice, I often see patients who feel that their vision is stable and therefore assume that their eyes are healthy. However, diabetic eye disease can progress silently in its early stages, without causing obvious symptoms.

Regular retinal assessment allows us to detect these changes early and take appropriate steps to protect long term vision.

How does diabetes affect the eyes?

Diabetes can affect the small blood vessels within the retina, which is the light sensitive tissue at the back of the eye responsible for vision.

Over time, elevated blood sugar levels can damage these delicate vessels, leading to leakage, swelling, or reduced blood supply to the retina.

This condition is known as diabetic retinopathy.

In some patients, diabetes can also lead to swelling within the macula, the central part of the retina responsible for detailed vision. This is referred to as diabetic macular oedema.

These changes may develop gradually and, importantly, may not cause symptoms immediately.

What symptoms should you be aware of?

One of the challenges with diabetic eye disease is that symptoms are often absent in the earlier stages.

As the condition progresses, patients may begin to notice:

• Blurred or fluctuating vision• Difficulty reading or focusing on fine detail

• Dark spots or floaters within the vision

• Distortion or missing areas of central vision

• Difficulty seeing clearly at night

What I always emphasise to patients is that waiting for symptoms to appear is not the safest approach.

By the time vision changes become noticeable, retinal damage may already be more advanced.

This is precisely why regular screening plays such an important role.

Why regular retinal screening matters

Retinal screening is designed to identify diabetic changes before they begin to affect vision significantly.

Early detection allows us to monitor the retina carefully, assess progression, and intervene at the appropriate time if treatment becomes necessary.

In many cases, patients who attend regular screening are diagnosed at an earlier stage, when management is more straightforward and visual outcomes are often better.

What I often explain is that retinal screening is not simply about identifying disease. It is about preserving future vision and reducing the risk of avoidable sight loss.

Regular assessment also provides reassurance when the retina remains stable, which is equally important for many patients living with diabetes.

⸻

What should you do if you have diabetes?

If you are living with diabetes, regular retinal assessment should be viewed as an essential part of your long term healthcare.

In most situations, I would recommend:

• Attending all diabetic retinal screening appointments consistently

• Arranging additional specialist assessment if you notice any changes in vision

• Maintaining good control of blood sugar, blood pressure, and cholesterol levels

• Understanding that retinal health can change even when vision feels normal

Detailed retinal imaging, including OCT scans when appropriate, allows me to examine the retina in high resolution and identify subtle changes at an early stage.

In some cases, continued observation is appropriate.

In others, early intervention may help stabilise the retina and preserve long term visual function.

The key is that management is guided by the findings within your individual eye.

⸻

Why choosing the right specialist matters

Diabetic retinal disease can vary significantly between individuals.

Some patients remain stable for many years, while others may require closer monitoring or treatment.

For this reason, specialist assessment and interpretation are essential.

In my practice, I focus on:

• Extensive experience in diabetic eye disease and medical retina conditions

• Detailed retinal imaging and OCT interpretation

• High volume experience in retinal treatments, including injections and laser

• A calm and personalised approach focused on preserving long term vision

I understand that many patients feel anxious when they are told that diabetes may be affecting their eyes.

My role is not only to identify and manage retinal disease, but also to provide clarity, reassurance, and a clear plan moving forward.

⸻

The bottom line

Diabetic eye disease often develops gradually and without obvious symptoms in the early stages.

The most important points are:

• Diabetes can affect the retina before vision changes become noticeable

• Regular retinal screening allows early detection of diabetic eye disease

• Early identification provides more opportunities to protect vision

• Specialist assessment is important in guiding long term management

Often, the most important question is not:

“Is my vision currently affected?”

But rather:

“Am I doing everything possible to protect my vision for the future?”

Considering your next step

If you are living with diabetes, or if you have been advised that there may be diabetic changes affecting your retina, a specialist and tailored assessment can provide valuable reassurance and clarity.

Diabetic retinal disease requires careful evaluation to understand the stage of the condition, the level of retinal involvement, and whether treatment or monitoring is appropriate.

A consultation with me will provide:

• A detailed retinal examination supported by advanced imaging

• A clear understanding of whether diabetes is affecting your retina

• Expert guidance on monitoring, treatment, and long term retinal care

• A personalised plan focused on protecting your future vision

If you would like clarity, reassurance, and a plan you feel confident in, I would be very happy to see you in clinic and guide you through your options.
