All designed to stress the visual system to its maximum.

Digital devices usage is increasing in everyday life, how many of us go any length of time before we are peering at our screens. I am as guilty of this as anyone else.

I have been asked a lot by patients what can be done to help? Do I need glasses? Should I sit closer/further away from the screen – and lots more similar questions.

 

The easiest piece of advice that I can give – that does work is the 20-20-20 rule:

 

 

202020

 

I have said to my kids and say to all my patients who are studying that taking a break from the books and picking up the Phone , Tablet or laptop to log into social media is not resting your eyes. Looking into the distance is when the eyes are at their most relaxed natural state.

 

There are lots of Apps available that use the 20 20 20 rule and have a timer that will alert you when its time to rest and relax the eyes. Look out the window – even better get outside and get some fresh air as well .

 

Good luck to all our patients in their exams and remember 20/20/20.

not a dry eye in the house

Itchy, sticky,gritty,dry,weepy,burning,red all words that are regularly used to describe the symptoms of dry eye.

We are seeing more and more people coming in to the practice with dry eye symptoms. It seems that a lot of patients feel that the underlying cause is VDU and Electronic gadget use.

Whilst this may well be a factor there are other things to consider – we live in centrally heated, sealed houses, our workplaces are generally very dry , we drive around in air conditioned cars, we do not keep ourselves properly hydrated, age ,  some medications, hormonal changes,  diet.

All of these can be factors – the important thing is what can be done to not only relieve the symptoms but also to determine the cause and implement a treatment plan.

 

At eyelines we can carry out a full dry eye assessment to determine what the cause is and can implement a treatment plan to not only relieve the symptoms in the short term but to mange the condition to give long term comfort.

 

Dry eye drops can be used to lubricate and hydrate the surface of the eye, in order to help to restore and maintain the natural balance of tear composition. Modern eye drops can also  protect the eye from environmental stresses. Some are also available in gel form for longer lasting relief, particularly overnight. We generally recommend eye drops that do not contain preservatives.

 

Heat Treatment on the eyelids can also give short term relief as well as helping to restore the efficiency of the tear flow.

 

 

 

Nutritional supplements can also be beneficial in treatment of dry eye.

 

 

 

 

 

A new treatment programme for dry eye that we are carrying out at eyelines is the Blephex treatment.

A soft medical grade sponge is moved across the eyelids and base of the eyelashes, whilst it spins it  removes debris and bacterial build-up that contributes to blockages of the glands in the eyelids.

Post Blephex treatment.

This is similar to a dental hygienist removing plaque, the unblocking of the glands and the removal of the biofilm build-up from the lids means long term relief and clean clear comfortable eyes.

cpd makes me feel old

I have just attended an all day conference in London hosted by one of our  suppliers Thea Pharaceuticals. It enabled me to gain some valuable CPD (Continuing  Professional  Development) and to catch up with some of the changes in Optics.

It was a full days course with a mix of Lectures Workshops and Peer reviews with a choice of options depending on what your requirements were.

I choose to attend a Peer Discussion on Interpretation of OCT cases. A Workshop on Dry Eye & Blepharitis Management and Lectures on Blinking and  Vitamin D Deficiency.

I managed to learn at least one new thing from each of the sessions I attended and will make sutble changes to what we do in practice – which really is the point of CPD.

When I first qualified it was not compulsary to do any further education – although I always have.  It now is a condition of registration with our professional body – but I  enjoy expanding by knowledge and it is always of benefit to the practice and our patients.

I also met up with a couple of Optometrists who I had not seen since we graduated – and we realised that we graduated nearly 25 years ago – hence why CPD makes me feel old.

 

 

abc 123 OCT

For almost a year now we have had an OCT Scanner within the practice at eyelines.

OCT or Optical Coherence Tomography is basically an ultrasound for the eye. Instead of using sound waves to image structures within the body the OCT uses light waves to enable high quality imaging of sub surface structures of the eye –  generally the Retina.

 

This is a non invasive technique that enables viewing and measurement of the layers of the retina  that will help in the diagnosis and monitoring of Glaucoma and conditions affecting the retina such as: Macular Degeneration; Vascular Disease; Diabetic Retinopathy; Retinal Detachments.

 

It has proven to be a very useful addition to our testing routine and we have spotted a number of conditions much earlier than we would have been able to in the past, and been able to refer for treatment or been able to monitor for change ourselves.

Here are some of the scan images

Scan showing sub retinal fluid around the Macular area that did not have much effect on the visual acuity. The patient was able to draw a vague area of distortion that he was aware of that matched the size and shape of the sub retinal fluid exactly.

 

 

eye 1

 

Scan showing a Macular hole and associated retinalschisis and epiretinal membrane.

 

Of course we never like discovering anything wrong with a patients eyes, it is much better to be able to do the scans and tell the patient that everything is perfectly healthy, but if we do pick up an abnormality we can get the patient referred to an eye hospital and treated.

 

The technology that is available to an optical practice now has changed by a huge amount even in the 20 or so years that I have been practicing. It will be interesting to see what the next developments are in the next few years.

 

 

 

camera-eye : eye-camera

I had a young patient (8 yrs old)  in for an eye examination  this week who was explaining to me how his teacher told the class that the human eye was based on a camera.

I did try and explain that really it was the other way round but he was having none of it because “his teacher told him that the eye was based on the camera and She is always correct”

The lens of the camera focuses light onto the film (or digital plate)

The lens inside your eye focus light onto the retina.

The aperture can be adjusted on a camera to let differing amouts of light in – in the eye it is the iris that does this job.

A camera lens can be moved backwards and forwards to change the focus – in the eye it is the Ciliary muscles that change the shape of the lens to alter the focus.

 

The young lad is quite keen on photography as am I and we got into a discussion about taking photos- it led to me looking through some of my old photo files – which is an excuse for me to post some images here.

The improvement in camera technology over the years means that all of us can become budding photographers with nothing more than our phones – although these were all taken with an Olympus E510 DSLR – except for the underwater shot of the turtle taken with a Fuji Fine Pix XP90

 

 

 

 

how do you solve a problem like myopia

In a previous blog post I mentioned the increase in Myopia that some have likened to an epidemic.

Apart from correcting the vision traditionally with spectacles or daily wear contact lenses what else is available – especially for  children.

Refractive Surgery has been an option in various form since the mid 1960’s and whilst techniques have been improving it is still usually not recommended for those under the age of 21 (or at least until any prescription changes have stabilised).

For a lot of  patients the thought of having any form of surgery will be enough to dissuade them from this option.

Happy snapping

Another possibility is Orthokeratology – or Ortho K – a technique of overnight contact lens wear that gently reshapes the cornea by about the thickness  of a hair. I have been using this technique in the practice for nearly 10 years.  (Previous Blog Post on Ortho K)

Until recently I have used Ortho K  mainly on adults but in the last 6 months I have been fitting the  lenses more and more to children with excellent results.

One of the first youngsters that I fitted last summer was Isabella  whose extended  family have been with the practice for many years. Isabella had been wearing spectacles for six months and her myopia was increasing rapidly, her father is quite myopic so Isabella was concerned that she would follow a similar pattern. We discussed all of the options available and decided to fit Ortho K – with great success.  Isabella has recently featured in a news article  about  Ortho K on ITV Meridian News.

Since Isabella’s success I have had an increasing number of children coming along and being fitted with Ortho K and it has proven to be a wonderful tool to enable children to cope with an active lifestyle without having to worry about vision, glasses or contact lenses during the day.
