Diabetic Retinopathy Treatment

Diabetic Retinopathy treatment aims to stop your sight getting worse. Early changes only need monitoring. If fragile new vessels grow or the macula swells, I may recommend laser, anti-VEGF injections or a steroid implant.

You can read about the condition itself on my Diabetic Retinopathy and maculopathy page, and the treatments page shows my full range of care.

What is Diabetic Retinopathy treatment, and what does it involve?

Diabetes can damage the tiny blood vessels in the Retina, the light-sensitive layer at the back of the eye. Treatment cannot bring back sight that has already been lost. Its job is to protect the vision you have now and stop the disease moving on to the next stage, as the NHS guide to Diabetic Retinopathy explains.

I monitor patients with Diabetic Retinopathy and treat both the proliferative form and diabetic maculopathy.

Diabetic Retinopathy symptoms and when to get urgent help

Early Retinopathy often causes no symptoms, which is why screening matters. Later, you may notice:

  • Gradually worsening or blurred vision
  • Dots and lines (floaters) in your vision
  • Struggling to see in low light
Your symptomPossible causeWhat to do
Eyesight suddenly gets worse, or new blurringRetinopathy or macular swellingUrgent GP appointment or NHS 111
New dots or lines (floaters), or poor sight in low lightRetinopathy changesContact my practice or your optician
Vision suddenly gets worse, or the eye is painful or red after treatmentComplication of treatmentCall my practice on 07438 437366, or NHS 111
Sudden loss of sight or a dark curtain over your visionBleeding or retinal detachmentCall 999 or go to A&E
Fever, confusion or fast breathing after a procedurePossible signs of infectionCall 999 or go to A&E

The NHS advises getting help straight away for sudden vision loss.

Who may need treatment?

Most people with early changes, called background or pre-proliferative Retinopathy, do not need treatment. They are monitored through regular screening instead. Treatment is usually considered for:

  • Proliferative Retinopathy, where fragile new blood vessels grow on the Retina and can bleed
  • Diabetic macular oedema, where leaking vessels make the macula (the centre of the Retina) swell and blur your central vision
  • Bleeding into the jelly of the eye or scar tissue on the Retina, which may need an operation

Your treatment options

Laser treatment (photocoagulation)

For proliferative disease, panretinal photocoagulation (PRP) places many small laser burns across the outer Retina to shrink abnormal vessels or stop them forming. It does not improve vision. The aim is to prevent severe sight loss. Some people need more than one session. Retinal laser treatment is part of my clinic.

Anti-VEGF injections

These medicines reduce leakage from damaged blood vessels and are mainly used when the macula is swollen. They are given as a course of intravitreal injections after anesthetic drops, with the interval between injections adjusted to how your eye responds. In some people vision improves as the swelling settles.

Steroid implant

A tiny implant placed inside the eye releases steroid medicine slowly to reduce swelling. I have used a wide range of intravitreal treatments, including steroids, and will explain whether an implant suits your eye.

Monitoring

If you have early changes, the plan is regular checks rather than treatment. The NHS invites people with diabetes aged 12 or over for screening every 1 or 2 years, and more often once changes appear.

Eye surgery

The NHS also lists eye surgery, to clear blood or scar tissue inside the eye, as a treatment. If you might need one, I will explain what it involves and who would carry it out.

Why patients choose me for Diabetic Retinopathy treatment

Diabetic eye disease is one of my specialist interests: I trained in medical Retina at Moorfields Eye Hospital and co-authored the Diabetic Retinopathy chapter of an online ophthalmology publication.

  • Medical Retina training: a Medical Retina fellowship at Moorfields Eye Hospital, London.
  • Registration: on the GMC Specialist Register since 2014 (GMC 6129624), after qualifying in Southampton in 2005 and gaining FRCOphth in 2012.
  • NHS work: Clinical Lead for the AMD service at West Hertfordshire (2015 to 2018), followed by five years as a consultant at Ashford and St Peter’s.
  • Research: a published paper in Eye (2015) on orthoptists giving intravitreal injections, and sub-investigator work in retinal trials.

My training and experience are set out on my About page.

Looking after your diabetes alongside eye treatment

Eye treatment goes hand in hand with good diabetes care. Keeping blood sugar, blood pressure and cholesterol as close to target as you can, and not smoking, all lower the risk of the Retinopathy getting worse.

Your GP or diabetes care team usually manages these, and NICE has published guidance on type 2 diabetes in adults. Please bring your latest results to your appointment.

Alternatives to treatment

If your Retinopathy is at an early stage, regular checks through NHS diabetic eye screening and good diabetes control are the usual alternative to laser or injections. Once new vessels or macular swelling appear, waiting carries a risk of further sight loss, so I will explain the options honestly.

What happens, step by step, on the day of laser treatment

1. Assessment

I check your vision and scan the Retina to plan the treatment.

2. Preparation

Drops widen your pupil, and anaesthetic drops are used. A contact lens holds it steady.

3. Laser

You see bright flashes and may feel stinging. It usually takes 10 to 30 minutes.

4. Afterwards

Your vision is dim and blurred for a few hours, so arrange a lift home.

How many treatments will I need?

It depends on the type of Retinopathy and how your eye responds. Laser is sometimes completed in one session and sometimes needs more. Injections for macular swelling are given as a course, and I look at the scan at each visit before deciding on the next interval. You go home with written aftercare instructions and can speak to my practice directly between appointments.

Recovery and risks after laser and injections

Driving after treatment

You cannot drive home after laser because of the dilating drops. GOV.UK lists Diabetic Retinopathy treated with laser among the eye conditions you must tell the DVLA about if it affects both eyes, or one eye when that is your only seeing eye. You can be fined up to £1,000 for not telling the DVLA about a condition that affects your driving.

Possible side effects

Kingston Hospital’s leaflet on PRP laser lists discomfort as common, and reduced night vision, loss of side vision and macular swelling as rarer effects. It says there is a less than 10% chance of the treatment affecting your ability to drive. Moorfields Eye Hospital puts the risk of a serious eye infection after an anti-VEGF injection at about one in 5,000.

FAQs about Diabetic Retinopathy treatment

Does laser treatment for Diabetic Retinopathy hurt?

Most people describe discomfort rather than pain. Anaesthetic drops are used first. You may feel stinging and see bright flashes during the session. Afterwards the eye can ache for a while, and your usual pain relief is fine to take.

Sight that has already been lost cannot usually be restored, so treatment aims to stop further damage. Injections for macular swelling may improve vision in some people, and good control of blood sugar, blood pressure and cholesterol helps protect the Retina.

No. Dilating drops blur your vision for several hours, so ask someone to drive you or book a taxi. If you have had laser treatment, check whether you need to tell the DVLA before you drive again.

Cover for Diabetic Retinopathy treatment depends on your policy. Check what it includes, any exclusions and the excess, and whether your insurer needs a GP or Optometrist referral. Get pre-authorisation before treatment starts. I can help with the paperwork.

Not if you are paying for yourself. You can contact me directly. Some policies do ask for a GP or Optometrist referral, so check your policy first. If you have a screening letter about your Retinopathy, please bring it with you.

Your vision is dim and blurred for a few hours after laser. Kingston Hospital’s leaflet says any temporary loss of vision usually settles by the next day. After an injection, a gritty eye or floaters usually settle within a few days.

Laser and injections are not. They are outpatient treatments given after anaesthetic drops, and you go home the same day. An operation is needed only for bleeding into the jelly of the eye or scar tissue on the Retina.

It can progress again, which is why follow-up matters. Laser sometimes needs more than one session, and injections are given as a course, with the interval based on your scan at each visit.

For early changes, yes: regular screening and good control of blood sugar, blood pressure and cholesterol. Once new vessels or macular swelling appear, treatment is usually advised to prevent severe sight loss.

A new consultation is £260 and a follow-up is £195. Laser, injections and implants are quoted after your assessment, depending on how many treatments you need.
