What is a Cataract

A cataract is a clouding of the natural lens of the eye, generally associated with the natural ageing process.


How do I know if I have a Cataract?

Common symptoms include blurred or double vision, glare from bright lights, difficulty driving at night, difficulty recognising colours and difficulty reading.


What Causes Cataracts?

Mainly ageing - over half the population aged over 65 have some degree of cataract. However, there are other causes including Diabetes, eye injuries and steroid medication.


Diagnosis & Assessment

A full ocular and medical history is taken by the Consultant Ophthalmologist who will ask you about your general health and your symptoms. You will undergo a complete eye examination measuring all aspects of your eye using the latest technology.



A cataract cannot be corrected using glasses. The only permanent treatment for cataracts is surgical removal which is usually a quick, safe and painless procedure taking about 20 minutes per eye and is performed under local anaesthetic. Usually one eye is treated at a time.

Removal is by microsurgery and essentially the cloudy lens in your eye is broken up and a new clear lens called an intraocular lens (IOL) is implanted. The intraocular lens is designed to last a lifetime.

At iSIGHT, we have a range of lenses to suit your lifestyle and your prescription. Your surgeon will discuss the range of lens options available to you. These lenses include multifocal, allowing you to focus at varying distances, and toric lenses to correct astigmatism.

Glaucoma is an eye condition where the optic nerve at the back of the eye becomes damaged. The optic nerve sends signals from the eye to the brain. Any damage to the nerve will result in damage to your eyesight.

Usually but not always, the damage occurs because pressure within the eye increases and damages nerve fibres which in turn leads to deterioration of field of vision. When a significant number of these nerve fibres are damaged, blind spots occur in the field of vision.

Sight loss in glaucoma usually happens very slowly over time and you may not have any early warning signs or notice deterioration in your vision until the later stages of the condition. There are an estimated half a million people in the UK alone, with undiagnosed Glaucoma.

The most common form of Glaucoma is called POAG - or Primary Open Angle Glaucoma, where sight loss starts around the edge of the field of vision and gradually moves inward In its advanced state, vision becomes narrower producing ‘tunnel vision’.


Predisposition to Glaucoma

• Women are more prone to develop Glaucoma than men

• You are more at risk if a close family member already has Glaucoma

• People with Afro caribbean heritage are more prone to the condition than caucasians

• Glaucoma is more common in later years, especially the over 40’s

Glaucoma is not curable, but there are very good methods of keeping it under control and preserving your sight.

At iSIGHT, we can offer you an annual pathway of care which includes diagnostic tests for:

• Visual Fields

• Eye pressure checks

• Ocular Coherence Tomography

• Corneal thickness assessment



The most common treatments for Glaucoma are eye drops, laser treatment or surgery.

Treatment of acute Glaucoma is initially with drugs to reduce the pressure within the eye.

Laser Trabeculoplasty - A tiny opening is created in the sclera (the white part of your eye) allowing fluid to drain away, thereby lowering the pressure in your eye

Trabeculectomy - This involves removing a piece of tissue from the sclera, creating a flap through which the fluid drains

Viscocanalostomy - the drainage canal is enlarged to allow more fluid to drain from the eye, thus lowering the pressure within your eye.

Age Related Macular Degeneration

Age Related Macular Degeneration

AMD accounts for about 50% of all visual impairment in the developed world and generally affects people over the age of 50.

It is an eye condition that affects a tiny part of the retina at the back of your eye which contains millions of light sensing cells called photoreceptors. These receptors are concentrated in the centre of the retina, the Macula which is about the size of a pinhead and is responsible for the fine detailed vision we need in order to be able to read.

Macular degeneration occurs when there is damage to these light sensing cells which then causes problems with your central vision. It is not painful.


Symptoms you may notice

•You may notice difficulty reading small print

•Seeing photographs clearly

•Watching tv

•You may notice a slight smudge in the centre of your vision

•Straight lines may look distorted

•Judging distance and height becomes difficult


Wet AMD produces new blood vessels that leak and cause build up of fluid.

Dry AMD does not produce new vessels.

Neither wet or dry AMD affect your peripheral vision, so never leads to total blindness.



This is the common form of AMD and it develops slowly, causing gradual changes in your central vision. Initially only one eye might be affected and symptoms may be difficult to recognise as your second eye compensates for the first. It takes a long time to get to its final stage. Dry AMD causes a blank patch in the central vision.

There is currently no treatment available to reverse Dry Amd, however there are lifestyle changes, including stopping smoking, which may help.


Diet and Nutrition

There’s some evidence that a diet rich in vitamins A , C and E – as well as substances called Lutein and Zeaxanthin – may slow the progression of dry AMD, and possibly even reduce your risk of getting wet AMD.

Lutein and zeaxanthin are not made within the body and can only be obtained from what we eat.

Foods high in vitamins A, C and E include: Oranges, kiwis, leafy green vegetables, tomatoes, carrots

Lutein sources: Spinach, kale, peas, mangoes, sweetcorn


For a more comprehensive food list visit

There’s no definitive proof that eating these foods will be effective for everyone with dry AMD, but this type of healthy diet has other important health benefits.

Dietary supplements are also available ,some of which claim to specifically improve eye health.
Check with your GP before taking supplements as they may not be suitable for everyone.



This develops very quickly and affects to your vision in a short period of time. Treatment is available and needs to be given quickly before the new blood vessels cause damage to your macula. If the blood vessels are left to grow, the scarring and sight loss is usually permanent.


Treatment of Wet AMD

The goal of treatment is to prevent further loss of vision and possibly improvement in your vision. Lucentis, Avastin and Eylea are medicines given by injection into the eye to slow or stop the growth of abnormal blood vessels and leakage.

The eye is numbed and the medication is injected. The procedure is repeated once a month for 3 months and later as necessary. Your surgeon will tell you how often you will need treatment. It is not usually painful, but you may feel a bit queasy afterwards.

Diabetic Retinopathy

Diabetic Retinopathy

Who is at risk of diabetic eye disease?

People with all types of diabetes. The risk increases the longer you have diabetes and the condition includes:-


Diabetic retinopathy - This is a complication of diabetes caused by high sugar levels that affect blood vessels at the back of the eye.


What are the symptoms of diabetic retinopathy?

You won’t usually notice diabetic retinopathy in the early stages, as it doesn’t tend to have any obvious symptoms until it’s more advanced. However, early signs of the condition can be picked up if you notice any of the symptoms below:

• Sudden loss of vision

• Gradually worsening vision

• Shapes or floaters

• Blurred or patchy vision

• Eye pain or redness


Can I reduce my risk of developing Diabetic Retinopathy?

You can reduce your risk of developing diabetic retinopathy, or help prevent it getting worse, by:

Controlling your blood sugar, blood pressure and cholesterol levels

Taking your diabetes medication regularly

Getting medical advice quickly if you notice any changes to your vision

Maintaining a healthy weight, eating a healthy balanced diet,exercising regularly, stopping smoking



You can be treated in many ways depending on the stage of your disease, but the benefits of regular screening cannot be overemphasised. In the early stages, your Consultant may advise that we monitor the progression of the disease, which is usually managed by regular 3- 6 monthly reviews.

If, however, your condition requires further investigation, we can offer you the most comprehensive screening and diagnostic tests available:

Retinal photography, fluorescein angiography, digital imaging of the retina.

Progression of your retinopathy to a more advanced stage may also require:

Argon Laser - this destroys the abnormal blood vessels outside your central vision and prevents continued growth of the fragile vessels and seals the leaking ones. The goal of the treatment is to arrest the progression of the disease.

Injections Anti - VEGF - Medication including Lucentis / Eylea / Novartis can be given by injection.

Children's Eyes

Children’s Eyes

If you are concerned about your child’s vision, it is important to get these worries addressed quickly. Your child’s vision is essential to their success in school.

Below are some warning signs for parents, teachers and carers to look out for:

• Consistently sitting too close to the TV

• Holding a book very close in order to read

• Miss out words, or repeat words when reading out loud

• Short attention span

• Poor hand/eye co-ordination

• Losing the place while reading or using a finger to guide the eyes

• Squinting or tilting the head to see better

• Frequent eye rubbing or blinking

• Sensitivity to light

• Closing one eye to read, watch TV or see better

• Avoiding activities which require near vision, such as reading or homework, or distance vision, such as participating in sports or other recreational activities

• Complaining of headaches or tired eyes

• Drop in school performance

If you can identify any of these traits in your child, it is important you have your child’s vision assessed.


Lazy Eye (Amblyopia)

It is a condition where vision in one eye does not develop fully during early childhood and your child sees less clearly out of the lazy eye and relies more on the other good eye. It is estimated that 1:50 children in the UK will develop lazy eye and are usually diagnosed around the age of 4. Young children are unaware that there is a problem, whilst older children may complain that they can’t see well through one eye. It is usually correctable if treated early.

Late treatment can mean that sight problems remain permanent.



This usually involves making the lazy eye work harder to see, using glasses or patches. Treatment is often effective, but quite slow. A squint is one of the most common causes of lazy eye


What is a squint?

A squint is a condition where the eyes point in different directions. Squints are common and affect around 1:20 children. They usually occur in young children.

Signs and symptoms of a squint

One of your child’s eyes may turn inwards, upwards or downwards, while the other eye looks forward. This may happen all the time, when tired or just when concentrating on a task. A divergent squint, where the eye turns outwards, is less common.

If you suspect your child has a squint, an orthoptist who is specially trained in this field, will test the sight and movements in each eye. Very often, the squinting eye has poor vision.

A squint can cause blurred or double vision, but children may not realise there’s a problem. Left untreated, lazy eye can develop. This is when the brain starts to ignore signals coming from the eye with the squint.


Advanced Orthoptics at iSIGHT

At iSIGHT we run a children’s assessment clinic, lead by an Advanced Orthoptist. Our orthoptic investigations check that both eyes work well together and that your child has binocular vision. Our Orthoptists work closely with Optometrists and Ophthalmologists who have special interest in children and patients with abnormal eye movements.

The team work together to plan the treatment of lazy eye, squint, astigmatism and dyslexia. Any other symptom that is present, can be referred to the appropriate clinician.

Children and young people can often struggle in educational environments where the support they need may not be sufficient to meet their specific needs. As a result they may experience low self esteem and low self confidence.

At iSIGHT, we offer a comprehensive orthoptic service with our advanced orthoptist, Jayne Court. Jayne joined us in 2013. She provides specialist orthoptic service to patients with complicated and routine ocular motility problems. She holds a regular Orthoptic Specific Learning Difficulties clinic to help children with eye problems related to, or contributing to specific learning difficulty.

“Ptosis” is the medical term for a drooping upper eyelid.

This can happen in one or both eyes and can sometimes affect your vision if it’s severe. For some patients, ptosis poses a cosmetic problem.


What Causes Ptosis?

A number of factors that affect the muscles, nerves, or skin of the eyelids can cause ptosis. The muscles that allow your eyelids to move up and down are called the levator muscles. They can weaken from injury or age. Some people may be born with eye muscles that are weaker than normal (congenital ptosis) causing them to develop ptosis at a young age. Ptosis can also occur as a result of long term contact lens wear, after cataract surgery or other eye operations or as part of the ageing process (acquired ptosis affects patients later in life).


What Are the Symptoms of Ptosis?

The primary symptom of ptosis is a visible drooping of the upper eyelid.




Treatment for ptosis varies depending upon the underlying condition but this will discussed at your consultation.


Ptosis surgery

This usually involves shortening the muscles or tendons that raise the lid. The muscle or tendon is then re-attached to your eyelid using sutures which are buried under the skin.

This is a condition where the eyelid has turned inwards towards the eye, causing the eyelashes to rub against the front of your eye (Cornea). If left untreated, it can cause corneal ulcers. Symptoms may be intermittent at first.



• Feeling that something is in your eye

• Sticky eye

• Some redness

• Infection and pain at front of the eye

• Watery eye

• Loss of some vision



Generally due to the relaxation of small muscles and tissue around the eyelid due to ageing.
Less common causes can include infection, inflammatory disease, damage or allergic reaction.



Initially, you can achieve short-term relief by simply pulling and taping your eyelid to your cheek to create tension, or you may be offered botulinum toxin injections to weaken the muscles that are pushing the lid inwards, or simply lubricating eye ointment.

Generally, however, Entropion is dealt with surgically. A small operation is performed under local anaesthetic to tighten your eyelid and return it to its former position. You may have to wear a patch overnight and then will commonly use an antibiotic ointment for a week. It is a very simple, safe procedure and most patients generally notice an improvement straight away.

ENTROPION is a very safe procedure if performed by a specialist OCULO-plastic surgeon.

Ectropion is when your lower lid turns outwards, away from your eye, exposing the surface of your inner eyelid.

This condition can cause eye dryness, excessive tears and irritation. Ectropion may be due to several factors, including facial paralysis and injury. The most common cause is muscle relaxation due to ageing.

If you have symptoms of ectropion, you should contact your GP. Without treatment, ectropion can lead to serious problems with your cornea. Eye drops can help to ease symptoms, but surgery is usually necessary


What causes Ectropion? 

The primary cause of ectropion is the muscle weakness or tissue relaxation that occurs as part of the normal ageing process. Your risk of developing ectropion increases with age.

Other factors include:

  • stroke
  • skin cancer
  • injury
  • scar tissue from injuries or burns
  • Bell’s palsy - a condition that damages the nerve controlling facial muscles. Prior surgery or radiation treatment of the eyelids 


What are the Symptoms of Ectropion? 

When you blink, your eyelids help distribute tears that protect and lubricate your eyes. The tears drain into the tear ducts that are inside your eyelids.

When the lower lid turns outward, it affects the way tears drain and this can result in a variety of symptoms, including:

  • Excessive tears
  • Excessive dryness 
  • Irritation
  • Burning
  • Redness 
  • Conjunctivitis 


Treatment for Ectropion 

Treatment depends on its severity and the underlying cause. Mild cases may not need treatment. Whilst awaiting treatment, eye drops can provide relief and protect your cornea from further damage. Exercise caution when wiping your eyes as this can aggravate the problem. Always wipe from the outer eye up to the nose, using an "up and in" motion.

Skin tape, an adhesive made specifically for the skin, may be used to lift the lower lid and hold it in place to relieve some symptoms. 



In more severe cases, surgery is necessary. It is a minor surgical procedure performed under local anaesthetic usually as a day case. Various techniques can be used depending on your particular condition.

It is a very simple, safe procedure and most patients generally notice an improvement straight away.

What Is Blepharoplasty?

Blepharoplasty is the removal and adjustment or repositioning of excess skin and fatty tissue.
It eliminates the drooping of skin into the visual field, greatly improving peripheral vision.

Determination of how much of your vision is affected is done by checking the peripheral visual field with an instrument called a Visual Field Analyser.


Eyelid Disorders

Although Blepharoplasty is usually performed for cosmetic reasons, to rejuvenate your looks, it can also be done as a functional surgical procedure to improve your vision if you have excess skin hanging down that impairs your vision.


Upper lid blepharoplasty surgery

The incisions are generally made along the natural crease of the skin where they are hidden and where they heal best. Excess skin and fatty tissue are then removed and muscle is adjusted. The surgery is very neat.


Benefits of Functional Blepharoplasty surgery at iSight:

• Our hospital conforms to all the stringent standards imposed by the Care quality commission

• We are proud of our low infection rates which are monitored continually

• Excellent Clinical / visual outcomes

Inflammatory Eye Disease or Uveitis

Inflammatory Eye Disease or Uveitis

What Is Uveitis?

Uveitis is a condition where there is swelling or inflammation in the middle coloured layer of the eye called the Uvea. It affects people in different ways depending on which part of the Uvea is affected, typically affecting people aged between 20 and 59 but it can occur at any age.

There are a wide range of potential causes of uveitis, many cases are thought to be related to our body’s immune system - called autoimmune disorder (where the immune system mistakenly attacks healthy tissue).


Symptoms you may notice

• Pain in one or both eyes

• Redness of the eye

• Sensitivity to light

• Eyeball feels tender

• Vision may be slightly blurred

• Floaters


Types of Uveitis

The Uvea is made up of:

• The Iris (coloured part of the eye)

• Ciliary body (Ring of muscle around the iris)

• Choroid (layer of tissue that supports the retina)

• Uveitis occurs when the Uvea becomes inflamed.



This is the most common form. Inflammation of the iris, sometimes called ‘iritis’.


Affecting the area around the ciliary body.

Posterior uveitis

Affecting the area at the back of the eye, the choroid and the retina.



For most people and depending upon the level of inflammation, a course of steroid eye drops is all the treatment needed to clear up the inflammation. Several different types of steroid medication may be used depending upon the type of uveitis you have.

Eye drops are often used for uveitis at the front of the eye whilst injections and tablets are more commonly used to treat the back and middle of the eye.


Temporary relief of your symptoms

• If your eyes become sensitive to light, you may like to wear dark glasses.

• If your eye is sore, place a warm flannel over the eye to soothe it.

• It is advisable to see your GP or Ophthalmologist if you suspect you may have uveitis

The sooner uveitis is treated, the better it responds to treatment.

Retinal Disease

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the centre of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail. 

Retinal disorders affect this vital tissue. They can affect your vision, and some can be serious enough to cause blindness 

• Macular degeneration - a disease that destroys your sharp, central vision 

• Diabetic eye disease 

• Retinal detachment - a medical emergency, when the retina is pulled away from the back of the eye 

• Macular pucker - scar tissue on the macula 

• Macular hole - a small break in the macula that usually happens to people over 60 

• Floaters - cobwebs or specks in your field of vision 

We offer an extensive range of clinical services for patients with retinal problems.

Double Vision

Double Vision

What is double vision?

Double vision is where you see two images of a single object. It may be constant or it may come and go.

The two images may be on top of one another, side by side or a mix of both. It can occur in one or both eyes. It is sometimes confused with blurred vision, in which you will see a single unclear image.


Double Vision in one eye

Double vision in one eye is called monocular double vision and you should be able to see normally when the unaffected eye is covered. This condition is not usually serious.

Conditions that can cause double vision in one eye can include:-

• Cataracts, or clouding of the lens in your eye

• Abnormalities of the cornea

• Dry eye

• Astigmatism, which is an irregularly shaped cornea, similar to a rugby ball.

•Retinal abnormalities such as macular degeneration


Double Vision in both eyes

Double vision with both eyes it is called binocular double vision. This happens as a result of both eyes not working together properly. Usually one image will disappear when one eye is closed This is a serious condition. If you haven’t had double vision before, you should have your vision checked quickly by your GP as it could be the sign of a more serious medical condition. You will probably be referred to a Neurologist, an Ophthalmologist or a Neuro-Ophthalmologist.

Conditions that can cause double vision in both eyes can include:-

• Diabetes

• Multiple sclerosis

• Head injury

• Brain Tumour

• Neurological problems



This will depend on whether you have double vision in one or both eyes. If you have monocular double vision caused by astigmatism, we may prescribe corrective lenses, glasses or contact lenses.

Each eye creates its own slightly different image because it is physically separated. Under normal circumstances this isn’t a problem, however, if your eye muscles or nerves are damaged, the muscles may not aligned properly or be able to control your eyes properly and you will develop double vision - this is known as a Squint.

Dry Eyes

Dry Eyes

Normally, tears keep the eye moist and comfortable, but sometimes the tear glands stop producing adequate tears or the tears dry up too quickly.

Dry eye syndrome can affect people of all ages. It is not usually a serious condition and tends to affect mainly those over the age of 50, with women being more susceptible than men. If left untreated, it can lead to complications.


Common Symptoms

• A sandy or gritty feeling as if there is something in your eye

• Burning or Itchy sensation in your eyes that you feel you need to scratch or rub.

• Red eyes.

• Eyes that sting, or feel as though they are burning.

• Painful eyes.



At iSIGHT we offer a range of treatments and clinical services for dry eye syndrome, from the mild, to the very severe.

In severe cases we can insert a tiny plug into your tear duct to block the duct and stop the drainage. There are several options, which your Consultant will discuss with you.

Collagen plugs - ideal for short term use in warm weather and are absorbed within 2/3 weeks.

Silicone/Soft plugs - they can give relief for dry eyes for up to 90 days.

Form Fit plugs - can give up to 6 months relief for dry eyes and are ideal for contact lens wearers.
They can be removed easily by flushing saline solution through the punctal opening.
