Detecting diabetic retinopathy

eye-15699_1920

What is diabetic retinopathy

Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back of the eye (retina). It can cause blindness if left undiagnosed and untreated.

However, it usually takes several years for diabetic retinopathy to reach a stage where it could threaten your sight.

To minimise the risk of this happening, people with diabetes should:

  • ensure they control their blood sugar levels, blood pressure and cholesterol
  • attend diabetic eye screening appointments – annual screening is offered to all people with diabetes aged 12 and over to pick up and treat any problems early on

How diabetes can affect the eyes

The retina is the light-sensitive layer of cells at the back of the eye that converts light into electrical signals. The signals are sent to the brain and the brain turns them into the images you see.

The retina needs a constant supply of blood, which it receives through a network of tiny blood vessels. Over time, a persistently high blood sugar level can damage these blood vessels in three main stages:

  • tiny bulges develop in the blood vessels, which may bleed slightly but don’t usually affect your vision – this is known as background retinopathy
  • more severe and widespread changes affect the blood vessels, including more significant bleeding into the eye – this is known as pre-proliferative retinopathy
  • scar tissue and new blood vessels, which are weak and bleed easily, develop on the retina – this is known as proliferative retinopathy and it can result in some loss of vision

However, if a problem with your eyes is picked up early, lifestyle changes and/or treatment can stop it getting worse.

Detect diabetic retinopathy at Henry Smith and Hamylton

We can detect early signs of diabetes with our advanced Retinal Imaging tests- Retinal digital photography, Optomap in our Leicester city centre and OCT in our Peterborough practice. It’s important to have regular eye examinations (at least every 2 years or more often) because we don’t always experience symptoms when there are eye problems. Early detection helps to keep the eyes healthy and vision clear.

Vista partners with Henry Smith and Hamilton opticians for 2017

Sight loss charity Vista has officially partnered with local opticians Henry Smith and Hamylton, starting off a year of fundraising for the charity.

The charity and the opticians have been linked for many years. They recently collaborated in the introduction of groundbreaking spectacle lenses, designed to improve vision in people with Macular Degeneration.

In celebration of Henry Smith and Hamylton’s 130th anniversary, the family-based opticians will be aiming to raise money for Vista with various fundraising activities throughout the year.

Becky Poole, Community and Corporate Fundraiser, said “This is an incredibly exciting partnership – to celebrate 130 years of Henry Smith and Hamylton, we have created a calendar of fundraising activities to raise vital funds for local people with sight loss.”

“From March until June, each colleague has pledged to walk 130 virtual miles in aid of Vista, which is the equivalent of walking from Leicester’s Haymarket Memorial Clock Tower to Brighton Pier!”

“Please show your support for Henry Smith and Hamylton on their fundraising journey.”
