Eye treatment for Night blindness

Millions of People all over the world experience night blindness, which could be a sign of something more serious to come. If your vision is normal during the day, but you struggle to see clearly at night or experience complete night blindness, in some cases the conditions are easily treated or it could be a serious condition like a congenital condition such as retinitis pigmentosa or a symptom of a condition that is not directly related to the eye.
Night vision trouble can crop up in those individuals who are always in the sun exposing their eyes to long durations of UV exposure. It could also be a sign of a vitamin A or zinc deficiency or cataracts to say the least.
What Causes Poor Night Vision?
Difficulty with night vision can stem from conditions ranging from exposure to the sun and vitamin deficiencies to a chronic disease such as cataracts.
Vitamin A deficiency – We have all heard the common “Old Wives Tale” of carrots being good for the eyes. This is in fact as true as it gets. Carrots contain vital vitamin A, which helps keep the retina healthy. Vitamin A is also found in many greens leafy vegetables and yellow vegetables. Night blindness caused by vitamin A deficiency is very rare in developed countries as diets are diverse and nutritious. This mostly happens in those people who have trouble absorbing nutrients and is therefore a secondary symptom various other conditions like Crohn’s Disease, celiac disease, cystic fibrosis, and pancreatic insufficient.
Cataracts - The first symptoms of cataracts is night blindness. Cataracts is associated with the lens, the part of the eye that is responsible for regulating light. In reduced light intensity, the cloudy lens struggles to see clearly and some people experience blurry vision, while others are affected with complete night blindness as the cloudiness progresses to severe stages.
Zinc- this mineral assists vitamin A to be used in the eye. Without zinc, vitamin A is unable to be utilized correctly. Zinc deficiency is a rare phenomenon as it found in abundance in meat, poultry, nuts, beans, and other popular foods. Zinc deficiency is caused by the same bodily conditions as with Vitamin A.
Diabetes night vision problems - high amounts of sugar in the blood stream is toxic and damages blood vessels. The retina, which is the part of the eye that has images focused on it, has many blood vessels flowing through it for nourishment and oxygen supply. These blood vessels can swell and burst, leading to night vision problems.
Sun exposure - if you have recently taken a trip to the desert of the beach and are having trouble seeing at night, this condition is only temporary and will probably resolve itself within two days. To avoid UV damage, doctors recommend wearing sunglasses at all times when outdoors on a sunny day.
Retinitis Pigmentosa - is a rare genetic disorder which affects people before the age of 30. The condition is noted by worsening night vision and day vision, although some part of your vision will still remain.
Eye Surgery - Lasik Eye Surgery patients also experience mild to severe light sensitivity which can last a few days to a week after surgery. Eye doctors will perform many tests to identify individuals who are at risk for developing the condition and recommend other treatments for those individuals, although the risk of having night vision trouble is still real.

What is Cataracts?

Cataract is the world's leading cause of blindness in people above the age of 50, although it is also seen in children mainly due to the intake of prescription medicine and hereditary influences. Cataracts affects the lens in the eyes and most often affects boths eyes simultaneously. Cataract affects about 18 million aging people worldwide but its symptoms are delayed with effective eye care and eye treatment early on. Cataracts does cause complete blindness eventually, however, it is also the few eye conditions that can be reversed. If blindness occurs Cataract Treatment in Dubai is available at Ebsaar Eye Surgery Center, where the damaged lens is removed and replaced with an artificial one, that works just as well.

Cataract is the name of the disease that happens in the lens of the eye. The lens is made of protien and water, which forms a clear gel like part of the eye, letting light to pass through to the back of the eye.

As we age the protiens in the lens separates from the water and collects in sections distorting or blocking light and images from falling on the retina (the back part of the eye that transmits signals to the brain using the optic nerve).

Although Cataract is diagnosed mostly in the older population, it not uncommon amongst young children and babies.

  • Age-related cataracts – As people age, the lens in the eyes loses it strength and eventually a build up of protein clouds your vision.
  • Congenital cataracts – seen in babies and young children is a result of poor development, injury and infection before or after birth.
  • Secondary cataracts – is a symptom of other ailments like diabetes or the exposure or consumption to radiation, ultra violet light, harmful or toxic substances or is the side effect of prescription medication such as corticosteroids (steroids prescribed for inflammation, digestive problems and hormone replacement) or Diuretics (pills prescribed for high blood pressure)
  • Traumatic cataracts – as the name suggests is caused after direct injury to the eye

  • There are three type of cataracts diagnosed in patients.

  • Cortical Cataract affecting the outer part of the lens and gradually moving towards the center.
  • Nuclear Cataract which begins in the center nucleus of the lens. When new cells form on the outter surface of the lens, the older ones are pushed to the centre which becomes the nucleus. In this type of cataract, the old cells are not able to retain their form, and hence the water and the protien separate.
  • Subcapsular Cataracts is caused mainly by prescription medication and occurs at the back of the lens. Diabetic, anti-inflammatory, and hormorne replacement medical conditions are all causes of this type of cataracts.

  • Prevention methods have not been fully understood yet, and as 18 million people are affected from cataract around the world, some scientific research claims that certain foods have either a positive or a negative effect on the disease. In one research it has been found that meat-eaters were more at risk of getting Cataract than people who included more fish and vegetables in their diet. Anti-Oxidents, certain vitamins like A, C, and E, zinc and regular eye exercise have been tested as preventive steps to delaying the onset of Cataracts.
    There are some concerns when it come to patients who have previously had LASIK surgery done and require Cataract surgery as they age. These concerns are addressed by providing your Ophthalmologist, with all the information of your visual health prior to and after the LASIK surgery was done. The Ophthalmologist will evaluate each case individually and advise accordingly.
