Eye Injections: Why They Are Needed and What They Do by Dr Rupal Morjaria

Eye injections are one of the most effective treatments that I use in managing a range of retinal conditions, including macular degeneration, diabetic eye disease and retinal vein occlusions.

I appreciate that the idea of an injection into the eye can feel concerning. For many patients, this is often the most worrying part of the treatment.

However, understanding why these injections are recommended, and what they are designed to do, can make a significant difference in how confident you feel about your care.

⸻

What are eye injections and why are they used?

Eye injections, also known as intravitreal injections, are used to deliver medication directly into the eye.

This allows the treatment to reach the retina, which is the part of the eye responsible for central vision, with a high level of precision.

These injections are most commonly used to treat conditions where there is abnormal blood vessel growth or fluid leakage within the retina.

The medication works by reducing this activity, helping to stabilise the retina and protect vision.

In many cases, these treatments are not only effective at preventing further deterioration, but can also improve vision over time.

⸻

What symptoms or conditions lead to this treatment?

I typically recommend eye injections when there are signs of active disease within the retina.

This may include:

• Distortion of central vision

• Blurred or reduced clarity

• Dark or missing areas in your vision

• Difficulty reading or recognising faces

These symptoms are often linked to underlying conditions such as:

• Wet macular degeneration

• Diabetic retinopathy affecting the macula

• Retinal vein occlusion

In many cases, detailed imaging such as OCT scans allows me to detect changes even before symptoms become severe.

This is one of the reasons why early assessment is so important.

Why early treatment matters

One of the key principles in managing retinal conditions is timing.

When fluid or abnormal blood vessel activity develops within the retina, it can begin to affect the delicate structures responsible for vision.

The longer this is left untreated, the greater the risk of permanent damage.

What I often explain to patients is that these injections are not simply about treating what you are experiencing now. They are about preserving the quality of vision you will rely on in the future.

Early treatment allows us to stabilise the condition before more significant changes occur.

⸻

What should you do if you are advised to have injections?

If you have been advised that eye injections may be appropriate, it is important to understand the reasoning behind this recommendation.

In most situations, I would suggest:

• Asking for a clear explanation of your diagnosis and what is happening within your retina

• Understanding how the treatment works in your specific case

• Attending follow up appointments consistently, as timing plays an important role

• Not delaying treatment unnecessarily, particularly if active disease is present

A structured treatment plan is usually required, and this may involve a series of injections over time. Each decision is guided by how your retina responds, rather than a fixed schedule.

⸻

Why choosing the right specialist matters

Retinal conditions are complex, and their management requires careful interpretation of both symptoms and imaging.

Eye injections are not a one size fits all treatment. They require precise timing, ongoing monitoring, and an understanding of how each individual eye responds.

In my practice, I focus on:

• Extensive experience in medical retina conditions, including macular degeneration and diabetic eye disease

• Detailed interpretation of retinal imaging to guide treatment decisions

• A high volume of experience in administering retinal injections

• A personalised approach to treatment planning and follow up

I understand that many patients feel apprehensive about injections. My role is not only to deliver treatment safely, but also to ensure that you feel informed, reassured, and confident in the plan we are following.

⸻

The bottom line

Eye injections are a highly effective way of managing a number of retinal conditions and protecting vision over time.

The most important points are:

• They deliver medication directly to the retina with precision

• They are used to stabilise or improve vision in specific retinal conditions

• Early treatment is important in preventing long term damage• Ongoing monitoring is essential to guide treatment

Often, the most important question is not: “Do I need injections?”

But rather: “What is the best way to protect my vision going forward?”

Considering your next step

If you have been told that you may need eye injections, or if you are experiencing changes in your vision, a specialist and tailored assessment can provide clarity and reassurance.

Retinal conditions require careful evaluation to understand both the cause and the most appropriate course of treatment.

A consultation with me will provide:

• A detailed retinal examination supported by advanced imaging

• A clear understanding of the underlying condition affecting your vision

• Expert guidance on whether injections are appropriate, and how they would be used in your case

• A personalised treatment plan focused on preserving your long term 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.
