Detached Retinal Surgery – Its Various Types

To understand how a detached retina surgery can be performed, we need to understand what retinal detachment is. In a layman’s language, it is a disorder of the eye where the retina gets separated from its attachment to its underlying tissue within the eye. Retina is a thin layer of light-sensitive tissues on the back wall of the eye. When we look around, light from the objects we are trying to see enters the eye. The light image is focused onto the retina by the cornea and the lens. The retina translates that focused image into neural impulses and sends them to the brain through the optic nerve. The retina can be compared to the film of the camera.

Retinal detachments are basically results of retinal break, tear or hole. The tear allows vitreous fluid to seep through it under the retina, and peel it away like a bubble in wallpaper. It is the fluid that separates the retina from the back of the eye. The common symptoms are flashing lights and floaters. Flashing lights are caused by the vitreous gel pulling on the retina or a looseness of the vitreous, which allows the vitreous gel to hit against the retina. Floaters on the other hand, are caused by condensation in the vitreous gel and are described by patients as spots, strands, or little flies. In case the patient experience a shadow or curtain that affects any part of the vision, this can indicate that a retinal tear has progressed to a detached retina and the patient should immediately consult a doctor without fail.

Retinal surgery is a type of eye surgery involving the repair of a detached retina. The retina transmits signals or messages to the optic nerve and the brain or nervous system, thus completing the cycle of vision. The specific type of surgery will depend on the type, size, and location of the detached retina.

Laser surgery or a freezing treatment called cryopexy may be recommended for small holes and tears. It creates a scar/adhesion around the retinal hole to prevent fluid from entering the hole and accumulating behind the retina and aggravating the retinal detachment. Cryopexy is mostly done in cases where there is a lot of fluid behind the hole.

A scleral buckle is a tiny synthetic band that is attached to the outside of the eyeball to gently push the wall of the eye against the detached retina. The bands are generally not removed. The most common side effect of a scleral operation is the myopic shift.

Vitrectomy involves removal of the vitreous gel and is combined with filling the eye with a gas bubble (SF6 or C3F8 gas). The gas is often injected into the eye to replace the vitreous and reattach the retina (known as a pneumopexy); the gas pushes the retina back against the wall of the eye.

Common Eating Myths and How to Avoid Them

Step away from the French fries! Just because they are free from trans fat doesn't mean they're good for you. This article will provide you with information on common eating myths and how to avoid them. Whether you're just looking to shed a few pounds or you want to lead a healthier lifestyle, the following information will be beneficial to you.

With all the food choice available to us, how do you tell the "good from the bad"? Well, based on what the top US nutrition experts have to say, here's a number of ways that we make bad food choices, and how we can make better ones.

If you feel hungry you must be hungry - Truth is, if you don't know when you're hungry, you won't know when you're full and you won't know when to stop. Too many times, we "guess" we're hungry, and go from there. A better solution is to rate how hungry you think you are (try a scale of something like 1 to 10) - then, eat slowly and as you eat, think about how your hunger changes. If you use a 1 to 10 scale, try to stay between 4 and 7. You don't want to be too hungry when you start, nor too full when you stop.

Supersize Me is a value - We always seem to look for a "value" when we're eating out, and that creates the false impression that if we supersize a restaurant meal, that we're saving money. Yet, in doing so, we're loosing our health. A better way to look at meal size is by judging with your palm, not your pocketbook. A good rule of thumb for serving size is, if it fits into the palm of your hand - that the right size. Make sure that your serving has one protein, one starch, one veggie, and one fruit, based on the serving that fits in the palm of your hand.

Fat is Bad - We have a mentality that fat is bad, which isn't true. What is more important, according to the American Heart Association, is telling the difference between saturated and trans fats (the bad fats), and eat the good, monounsaturated and polyunsaturated fats. You can find these fats in fish, nuts, avocados, soybean and canola oils. If you track total calories, you don't have to worry about how much fat you eat, just what kind of fat.

If it's liquid, it has no calories - Most sugared drinks - including sodas and juices -have a high concentration of high-fructose corn syrup as it's sweetener. But, fructose contains no enzymes, vitamins or minerals and also interferes with the heart's ability to use key minerals vital for a healthy heart. So, instead of sugared drinks, try drinking water or tea. Tea is calorie free, promotes heart health, strengthens bones & teeth, protects the skin - and may help you avoid several types of cancer!

Frozen Entrees are healthy - Many times, with our hectic schedules, it seems as though throwing a frozen entree in the microwave seems the best way to take care of a meal. But, eating too many processed foods like the types you find in the frozen food isle of your nearby supermarket may leave you short on fiber and important antioxidants such as vitamin C. So, if you do find yourself in a situation where having a frozen meal is your only choice, compliment it with a green salad, a whole wheat roll, and some fruit for dessert.
