Digital Retinal Screening

We are delighted to announce the acquisition of new imaging equipment which will allow us to screen for and monitor ocular pathology in both the anterior and posterior segments of the Eye.

 

Our new DRS (Digital Retinal Screener) produces high quality scans of the back of the eye which will improve early diagnosis of a wide variety of retinal and posterior segment  eye disorders including Diabetic Retinopathy, Macular Degeneration, Ocular Cancer, Retinal Hypertension, Glaucoma, Cataract and Posterior Uveitis.

Please see a pair of sample images of a Right and Left Eye showing a healthy retina (lining of the back of the eye), taken with the DRS.

 

Please see below some examples of the types of retinal pathology that can be picked up:

 

Wet Macular Degeneration.

An example of the retinal changes that can occur in cases of Wet Macular Degeneration. Wet age-related macular degeneration (AMD) develops when abnormal blood vessels grow into the macula. These leak blood or fluid which leads to scarring of the macula and rapid loss of central vision. Wet AMD can develop very suddenly but it can now be treated if caught quickly. Fast referral to a hospital specialist is essential.

 

Dry  Macular Degeneration

Dry age-related macular degeneration (AMD) is a slow deterioration of the cells of the macula, as the retinal cells die off and are not renewed often over many years. The term dry does not mean the person has dry eyes, just that the condition is not wet AMD. The progression of dry AMD varies, but in most people it develops over many months or years. People often carry on as normal for some time.

 

Diabetic Retinopathy.

Diabetes causes long term damage to small blood vessels throughout the body, including the retina. As a result of blood sugar fluctuations, the walls of the blood vessels within the retinal tissue weaken, causing them to leak fluid and cause significant visual impairment. Diabetes is the leading cause of blindness in the Western world.

There are two types of DR:

  • Non-proliferative diabetic retinopathy (NPDR): This is the milder form of diabetic retinopathy and features early, small areas of  haemorrhaging within the retina.It  is usually symptomless.
  • Proliferative diabetic retinopathy (PDR): PDR is the most advanced stage of diabetic retinopathy and refers to the formation of new, abnormal blood vessels in the retina. These new blood vessels are much more prone to leakage.

 

Hypertensive Retinopathy

Over time, high blood pressure can cause damage to the retina’s blood vessels, limit the retina’s function, and put pressure on the optic nerve, causing vision problems.

 

Please contact the practice on 02890 613485  to request a scan, or for further details.

 

We are also able to provide Digital Imaging Diagnostics for Anterior Eye Disorders and Pathologies using our new Slit Lamp Imaging System. This helps in the diagnosis of disorders such as Blepharitis, Dry Eye, Conjunctivitis, Sub-Conjunctival Haemorrhage, Corneal Ulcers, Corneal Foreign Bodies, Closed Angle Glaucoma, Iritis and Cataract.

 

Please see below a sample image of the Anterior part of the eye. below:

 

Please see below a sample image showing the type of changes that can occur with the common Eyelid Condition Blepharitis:

Blepharitis is a common inflammatory condition that typically affects the eyelids, but can secondarily involve the cornea and conjunctiva. Symptoms include a foreign body sensation or a burning sensation, excessive tearing, itching, sensitivity to light, red and swollen eyelids, blurred vision, discharge, flaky skin on the eyelids and dry eyes. Patients with blepharitis sometimes have an underlying rosacea (or acne rosacea), which is a skin condition characterized with redness of the cheeks and telangiectasis of facial skin.
