An update on the Covid-19 virus and our stores

Given the unprecedented situation in the UK regarding the COVID-19 virus we feel that it is important to reassure you that we are continuing to keep our practice clean and safe for both you and our team. We intend to keep the practices open for as long as possible to provide the service that is needed for our patients.

You will appreciate that as an optical practice we work in an environment where the prevention of the spread of a whole range of infections is woven into everything that we do. Nevertheless, we are paying particular attention the latest government guidance on the transmission of coronavirus.

All of the frames on display, the equipment we use and all surfaces are cleaned and disinfected regularly to keep the practice as sterile as needed and as often as needed.

Know the guidance

Before attending the practice for your next appointment, we would be grateful if you would review the most up to date government guidance – just click this link https://www/nhs.uk/conditions/coronavirus-covd19/

Keep us in the loop

Please remember that we are open, as normal, and to call us on the practice telephone number or email us to let us know if you wish to reschedule any of your booked appointments. We would be happy to schedule an alternative date for you. 

At your next appointment

Please forgive us if we don’t shake hands – but we are however happy to do the elbow bump – just ask! 

You’ll notice that we’ve removed some non-essential items in the reception area including the magazines. They will return once this is all over!

As a team, we are doing everything we possibly can to remain fit, well and able to work so that we can continue to provide our usual high standard of dental care for you.

Thank you for your support in keeping everyone safe.

Macular Degeneration

Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in people over 50 years of age, affecting an estimated 500,000 people in the UK and 70,000 people in Ireland, with over 12 million sufferers across Europe (BMJ. Mar 1, 2003; 326(7387): 485–488) This eye disease is particularly frustrating because it results in a loss of central vision. In other words, someone with AMD can see everything except what he/she is looking directly at, and is therefore unable to read, watch TV, recognise faces or drive. There is currently an epidemic of AMD, largely because we are all living so long and, some say, our eyes have been exposed to ultraviolet radiation for all those living years.

It is now believed that that damage by free radicals causing oxidative stress within the eye trigger changes that cause AMD to develop. Free radicals are unstable molecules, and are produced in response to a person using oxygen, and in response to blue light entering the eye. Because we use oxygen to live and because we are constantly exposed to blue light, damage caused by free radicals is unavoidable (the cost of living) … but it CAN be minimised.

Who is at risk of developing AMD

The three most important and established risk factors for AMD include:

  • Increasing age
  • Cigarette smoking
  • Having a family history of AMD

Other risk factors include:

  • Obesity
  • Genetic factors*
  • Female gender
  • White race
  • Light iris colour
  • Sunlight exposure
  • High cholesterol
  • Hypertension (high blood pressure)
  • Poor diet
  • Low macular pigment levels

* Genetic factors have been shown to contribute significantly to the development of AMD; for example having first degree relatives with AMD increases the lifetime risk 2-3 fold. Variants in five regions of the genome have been identified that increase the risk of developing AMD: a variant in the CFH gene on chromosome 1, a variant in the ARMS2/HTRA1 genes on chromosome 10, two variants in the C2/CFB genes on chromosome 6 and one variant in the C3 gene on chromosome 19. CFH, C2, CFB and C3 are involved in the immune response and controlling inflammation in the body. Individuals with certain variants in these genes may be at higher risk for inflammation-induced damage to the retina.

What can be done to prevent AMD developing?

Some of the above risk factors for AMD are modifiable. In other words, people have control over these risk factors. For example, a person can stop smoking cigarettes, improve their diet and most importantly, increase their macular pigment level. There are two main types of Age-related Macular Degeneration:

Dry Type

This type progresses at a slower rate but can cause loss of reading vision and central vision over time. In this type, there is no leakage of blood or protein under the retina and is generally the least harmful to vision . There is no specific treatment but recent mounting evidence suggests that cessation of smoking, taking regular high dose antioxidant vitamins and protection from blue light are the actions that are considered most modifiable in order to reduce the risk of progression of the disease to the wet form.

Wet Type

In the wet type of AMD Soft fatty deposits, called drusen, form on the lowest layer of the retina and trigger a response that leads to new blood vessels forming in the area. New blood vessels are usually weak and ‘leaky’ since they are young and the cells that make up their walls have not had time to compress and become tight. This type of macular degeneration is due to the abnormal blood vessels (called choroidal new vessels) growing under the macula (central part of the retina used for reading and central vision). These new vessels have the potential to leak and bleed under the retina, with the capacity to rapidly distort and damage central vision. Blindness rarely results because peripheral vision is usually preserved. Drusen are yellow proteinaceous deposits under the macula and may be a precursor to wet AMD development. They may remain stable for long periods of time. In both these types of macular degeneration the central vision may become damaged but the peripheral vision is usually not affected and so blindness in rarely, if ever, the final outcome.
