[:en]30 June 2014 (Dubai, United Arab Emirates): According to the World Health Organisation (WHO), cataracts are the leading cause of blindness and visual impairment in the world (47.9%) and their prevalence increases each year as the world’s population ages. Eye experts at Moorfields Eye Hospital Dubai are warning about the rising incidence of cataracts in the GCC’s young but ageing population (over 65 segment growing from 1.2% in 2015 to 14.2% of the GCC population by 2050) and especially amongst the large diabetic community in the GCC, where the risk of cataracts is much higher. Age and diabetes are the two main risk factors for cataracts.
Cataracts cause gradual blurring of the vision. In 2002, cataracts caused reversible blindness in more than 17 million of the 37 million blind individuals worldwide; this figure is projected to reach 40 million by 2020. In the Gulf region, an ageing population and high incidence of diabetes is raising concerns among eye experts.
‘Cataract’ is an English word for a large waterfall and is also a very apt term used to describe a gradual loss of vision as the lens of the eye becomes opaque and so is like looking through a waterfall. Cataracts are cloudy opacifications of the lens of the eye that interfere with vision. Cataracts can be caused by a wide variety of factors. The lens of the eye is made up of cells that contain protein and with increasing age and after damage to the lens cells by trauma, illness or certain medications over time the protein becomes denser and the lens may start to cloud over.Age is the single most important risk factor for cataracts, which are rare before the age of 40 – although babies can also be born with cataracts. Diabetes is one of the other key factors that result in the development of cataracts; people with diabetes mellitus statistically face a 60% greater risk of developing cataracts.
As with most complications of diabetes, maintaining good control of blood sugar levels will help to reduce risk. Research has shown that people with type 2 diabetes who lower their HbA1c level by just 1% can reduce their risk of cataracts by 19%.Dr Edoardo Zinicola, Consultant Vitreoretinal Surgeon and Medical Retina Specialist at Moorfields Eye Hospital Dubai, the first overseas branch of the world’s largest eye hospital, comments: “We cannot turn back time and even the young population of the Middle East will eventually age, potentially creating a wave of chronic disease – principally diabetes, which will create this perfect storm for cataracts and other serious eye complications. Cataracts generally develop and progress slowly and can eventually lead to significant vision problems. The good news is that cataracts can be treated very effectively with modern surgery to remove the cloudy lens and insert a high quality lens implant. Once treated, cataracts do not return.”
Moorfields is inviting the community and people with diabetes for cataract screening, diagnosis and assessment, as well as surgery where appropriate, and is offering special rates during the summer months.
Moorfields Eye Hospital Dubai organizes Glaucoma Symposium to brief UAE specialists on latest advances and risks to people with diabetes
[:en]17 November 2014 (Dubai, United Arab Emirates): Moorfields Eye Hospital Dubai, supported by the Emirates Medical Association Ophthalmic Society, has organized a Glaucoma Symposium for specialists from across the UAE to brief them on the latest developments in the diagnosis and treatment of the eye disease. Glaucoma generally affects older people but uncontrolled diabetes is also a major risk factor, making Glaucoma a health issue even for the relatively young population of the UAE.
The World Health Authority estimates that Glaucoma affects around 60 million people globally. Glaucoma is the second leading cause of blindness worldwide and the number one cause of irreversible blindness. There is no cure, however, the disease is treatable and blindness can be prevented through early diagnosis, highlighting the importance of screening.
At the Glaucoma Symposium, expert speakers from four leading eye hospitals and clinics in Abu Dhabi and Dubai took the group of UAE ophthalmologists through the various forms of the disease and the latest in medications and surgical techniques, during the half-day session at the Al Bustan Rotana Hotel in Dubai on Friday 7th November. The symposium attracted more than 100 delegates to the CME (Continuing Medical Education) accredited event.
Glaucoma is a group of eye diseases that cause progressive damage of the optic nerve. If left untreated, most types of glaucoma result (without warning or obvious symptoms to the patient) in increasing visual damage and may lead to blindness. Once this has happened, the visual damage is permanent, which is why glaucoma is described as the “silent blinding disease” or the “sneak thief of sight”.
According to the World Health Organization, the number of people estimated to be blind as a result of primary glaucoma is 4.5 million, accounting for slightly more than 12 per cent of all global blindness. The incidence of some types of Glaucoma rises with age and its progression is more frequent in people of African origin. Although children and young adults can be affected by Glaucoma, high risk groups include older people (with an increasing risk over 40 years of age), uncontrolled diabetics and those with a family history of Glaucoma.
Speaking on the sidelines of the Glaucoma Symposium, where he was a principal speaker, Dr Mohammed Sohaib Mustafa, Consultant Glaucoma Surgeon at Moorfields Eye Hospital Dubai, commented: “Glaucoma has no symptoms in its early stages and up to 40 per cent loss of sight can occur before any problem is noticed by the sufferer. This is why we wanted to bring together eye care professionals in the UAE for this Glaucoma Symposium. We are advising the community in Dubai – and especially people with diabetes and anyone over the age of 40 – to undertake regular screening every year. It really could save your eyesight. We have a relatively young population in the UAE but with a high incidence of diabetes and so, as the population ages, there is the risk of an increase of Glaucoma.”
Glaucoma is treated with eye drops or surgery (conventional or laser) which can halt or slow-down the disease and further vision loss. Research aims to uncover the mechanisms for the improper levels of intra-ocular pressure, nerve damage and the role of genes. Early detection is essential to limiting visual impairment and preventing the progression towards severe visual handicap or blindness. Screening for Glaucoma involves a mandatory eye pressure check, evaluation of the optic nerve at the back of the eye by a specialist doctor and visualfields test if any changes are seen at the previous exams. All tests are pain free and easy to assess the disease when performed in proper ophthalmic hospitals or clinics. Screening should be done every 12 months.
Moorfields Eye Hospital Dubai supports Dubai Healthcare City’s ‘World Diabetes Day campaign’, a public health screening event offering more than 10 tests for children and adults
[:en]Vision experts will provide complimentary consultations to explain some of the most common and serious complications of diabetes
12 November 2014 (Dubai, United Arab Emirates): To mark World Diabetes Day 2014, Moorfields Eye Hospital Dubai will support Dubai Healthcare City’s public health screening campaign aimed to educate the community about diabetes through consultations and health checks.
The event, organized by DHCC, the world’s largest healthcare free zone, will take place on Thursday, November 13, 4pm-8pm, at The Executive Towers, Business Bay, Dubai. A team from the hospital will provide residents seeking consultations with medical history review, intra-ocular pressure tests, visual acuity checks, and retinal imaging. The vision tests will use state-of-the-art technology.
Retinal diseases, such as diabetic retinopathy, are some of the most common complications caused by diabetes and can lead to permanent loss of vision if not treated. To help the UAE’s large population of people with diabetes manage the disease, Moorfields has established a specialist team of three retinal consultant surgeons and ophthalmologists in Dubai focusing on medical retinal diseases, such as diabetes. Dr. Avinash Gurbaxani, Consultant Ophthalmic Surgeon at Moorfields Eye Hospital Dubai, comments: “Vision-related problems are some of the most common and serious complications of diabetes. Of course, the single most effective treatment for diabetic eye disease is prevention – good control of diabetes and any associated high blood pressure can delay or avoid significant eye problems. Prevention of diabetic eye disease starts with regular eye examinations which can so often provide an indicator of the diabetes or blood pressure control. Regular screening should begin from an early age, regardless of whether there are vision symptoms or not.”
Diabetic retinopathy
Every cell in the eye (and, indeed, the body) is affected by the biochemical changes of diabetes. In practice, however, retinopathy is a disease of blood vessels – sometimes they wither away, sometimes they leak fluids when they shouldn’t and sometimes they grow where they do not belong. The blood vessels in the retina are uniquely prone to going wrong in this way, although the same changes can be found elsewhere in the body.
Treating diabetic retinopathy
According to Dr Edoardo Zinicola, Consultant Vitreoretinal Surgeon and Medical Retina Specialist at Moorfields Eye Hospital Dubai, once retinopathy is present, direct eye treatment may be needed and the type of treatment depends on the problem. “There is no effective treatment for the parts of the retina where blood vessels have disappeared,” he comments. “Laser photocoagulation remains the first line of treatment for both new and leaking vessels. Injections of steroids and medicines known as VEGF blocking agents also have a role and where the eye disease is advanced then surgery can help.”
Prevention tips for patients at risk of diabetic retinopathy
- Control the diabetes as well as you can
- Control high blood pressure
- Do not smoke
- Get regular eye checks
- Take charge of your own health
