London Eye Doctor: How VEP and ERG Have Shaped Paediatric Diagnosis

It is not always easy to determine how your baby or young kid can see. For this reason, experts in paediatric ophthalmology have devised various electrodiagnostic means to detect vision problems in the young. They include the VEP and ERG tests. These initials stand for ‘visual evoked potential’ and ‘electroretinogram,’ respectively.

6 Signs Your Child May Have Vision Problems


If your child has uncorrected vision issues, then it could really impact on their development. Here are a few warning signs you should look out for.
1. Always sitting too close to the television or holding books close
While sitting close to the television will not cause square eyes as the myth says, it can be an indicator that your child is struggling to see and the same if your child has to hold a book very close to see, it could mean your child is near-sighted.



2. Regular eye rubbing
Children do often rub their eyes when they are tired or upset but if your child is regularly rubbing their eyes even when being active or trying to concentrate it could be a sign of a vision problem, so best to get it checked out at an eye clinic.



3. Problems with hand-eye coordination
A child is not going to be perfect at catching a ball for example, but if you find you child constantly struggling with hand-eye coordination tasks or activities this could also be a sign of a visual issue.



4. Excessive tearing or sensitive to light
If your child is sensitive to indoor lighting, flashes of light; such as a camera, or the sunlight they could have photophobia or extreme light sensitivity, this can cause headaches and nausea but having light sensitivity could be an array of eye conditions so speak to your GP or eye doctor if you think this is a problem for your child.



5. Closing one eye
Does your child close one eye when watching television or reading? This could be a sign of a refractive or binocular problem that stops the eyes from working correctly together.



6. Eyes not pointing in the same direction
If your child’s eyes do not point in the same direction this could be due to a squint or lazy eye for example. This should be checked by your GP or eye doctor and the earlier it is picked up the easier it may be to correct with glasses, patches or surgery.
Remember a child needs regular eye tests too, from birth until the child is about 4 or 5 this will probably be checked when the child has normal follow ups but after this age they should have an eye test as least every 2 years at an optician.

Mr Hamada at UK Cross-linking Consortium Meeting

24th May 2016 – Mr Hamada has been invited to this meeting to speak about Epithelium off cross-linking: review of clinical studies and long-term follow-up data. This meeting is the first of its kind in the UK and will cover the most important issues relating to cross-linking. It will be attended by most cornea surgeons who have an interest in corneal cross linking (CXL). CXL has been approved by NICE as the treatment of choice to stop or slow keratoconus progression. Children and young patients are the ones who will benefit the most because keratoconus at a younger age is normally aggressive and fastest progressive. Keratoconus is found in 1/300 in Asian and 1/2000 in Caucasians.

The Cornea and Injury

Generally, the cornea manages well with a minor injury. The cornea is extremely sensitive and if it scratched then healthy cells move over very quickly to cover the damage before an infection takes place and before vision is affected. However, if the injury is deep, the healing course can take much longer and can cause pain, tearing, blurry vision and redness amongst other side effects. It is also very important to see an eye doctor if you have a deeper corneal injury as it can cause scarring, impair vision and haze. If this happens then a corneal transplant might be necessary.

Hearing that you need any kind of surgery can be alarming and leave you bracing yourself for a stay in hospital. However, if you or an elderly relative needs an operation to remove a cataract, you’ll be relieved to know that it is usually carried out under local anaesthetic and done in under 20 minutes. This means that you can be treated as a day patient, although you can be given sedation. If you need cataracts treated in both eyes, it will usually be done on separate occasions.
