Blurred Vision or Decreased Colour Sensitivity May Indicate Retinal Diseases

Early detection of AMD and DME increases the possibility of preventing vision loss, and according to Azad, treatment becomes difficult for those who have completely lost their sight.

People experiencing blurred vision or decreased colour sensitivity need to get their eyes checked as these seemingly minor problems may actually indicate retinal diseases that account for a significant share of the vision loss burden in the world, experts have warned.

Retinal diseases often get underdiagnosed as people feel no pain when symptoms start showing up and the other eye often compensates for the poor eye, experts from the All India Opthalmological Society (AIOS) said at a workshop on retinal disease here.

“The common symptoms of retinal disorders like AMD include blurred or distorted vision, dark spots in central vision or straight lines appearing wavy,” said Rajvardhan Azad, President of the All India Collegium of Ophthalmology, a fellowship programme of AIOS.

“These diseases often go underdiagnosed as they get noticed only when profound loss of eye sight occurs or the patient closes one eye. It is, therefore, imperative to understand the symptoms and seek expert advice as early diagnosis can help prevent loss of vision,” Azad, who is also an eye specialist at Bharti Eye Hospital in New Delhi, said.

Early detection of AMD and DME increases the possibility of preventing vision loss, and according to Azad, treatment becomes difficult for those who have completely lost their sight.

Some of the treatment options available in India include laser photocoagulation, anti-VEGF (Vascular Endothelial Growth Factor) injections and combination therapy which includes laser and anti-VEGF treatment.

People with diabetes should be especially alert as they are more prone to develop diabetic retinopathy, Azad said. (IANS)

An Orange a Day can Keep You Away From Age-related Vision Loss

Age is the strongest known risk factor and the disease is more likely to occur after the age of 50. There is currently no cure for the disease

If you want to prevent losing your vision as you age and keep your eyes healthy, eat oranges daily, says a study led by an Indian origin researcher.

Macular degeneration is a condition associated with old age that causes vision loss at the centre of the field of vision.

The results showed that people who ate at least one serving of oranges every day had more than 60 per cent reduced risk of developing late macular degeneration 15 years later.

The effect may be due to flavonoids present in oranges that help prevent vision loss.

Flavonoids are powerful antioxidants found in almost all fruits and vegetables, and they have important anti-inflammatory benefits for the immune system.

Having an orange once in a week may also  prevent age-related vision loss.

“Essentially we found that people who eat at least one serve of orange every day have a reduced risk of developing macular degeneration compared with people who never eat oranges,” said lead researcher Bamini Gopinath from the University of Sydney.

“Even eating an orange once a week seems to offer significant benefits,” she added.

For the study, published in American Journal of Clinical Nutrition, the team interviewed more than 2,000 people aged over 50 and followed them over a period of 15 years.

Gopinath explained that previously most of the researches had focused on the effects of common nutrients such as Vitamins C, E and A on the eyes.

The team also looked at other flavonoid containing foods like tea, apple, red wine. However they did not find any relation between other sources and protection of eyes against the disease.
