Marmer Medical Center : Quick RP Overview | Retinitis Pigmentosa Overview

Retinitis pigmentosa (RP) is a rare, hereditary disease that causes the rod photoreceptors in the retina to gradually degenerate. The rods are located in the periphery of the retina and are responsible for peripheral and night vision. Cones, another type of photoreceptor, are densely concentrated in the macula. The cones are responsible for central visual acuity and color vision.

The disease may be X-linked (passed from a mother to her son), autosomal recessive (genes required from both parents) or autosomal dominant (gene required from one parent) trait. Since it is often a sex-linked disease, retinitis pigmentosa affects males more than females.

People with RP usually first notice difficulty seeing in dim lighting and gradually lose peripheral vision. The course of RP varies. For some, the affect on vision may be mild. Others experience a progression of the disease that leads to blindness.

In many cases, RP is diagnosed during childhood when the symptoms begin to become apparent. However, depending on the progression of the disease, it may not be detected until later in life.

Signs and Symptoms

Lasik Surgery For Presbyopia

Laser Eye Surgery and in particular LASIK surgery, is really a safe efficient and predictable technique of correcting nearsightedness, farsightedness and astigmatism. These common vision problems occur because the refractive power of the eyes is not accurate so as to allow light to concentrate at a precise point on your retina. An additional kind of common vision issue that is because of a deficiency in the actual focusing mechanism within your eyes is called presbyopia.

Presbyopia, which literally means “old eyes”, is really a normal and expected consequence with the aging procedure. The crystalline lens inside your eyes is composed of proteins. These proteins are soft and flexible when you are younger. Beginning as you approach your 40′s presbyopia occurs as the protein composition with the crystalline lens changes, creating it harder and less flexible. When the crystalline lens loses its ability to flex, it’s no longer able to change its shape and effectively bend light rays as sharply, and the ability to concentrate on close to objects is diminished. As mentioned above, the clinical symptoms of presbyopia typically commence between age forty and fifty and progressively worsen through age sixty-five. When presbyopia begins, people who already wear glasses might require bifocals or trifocals, and those who’ve in no way worn glasses might require reading glasses.

The most typical treatment for presbyopia is the use of reading glasses, either from the rack at your pharmacy or via prescription from your eye doctor. Eyeglasses treat the symptom but don’t cure the condition.

Conductive Keratoplasty (CK) uses radio energy to steepen the cornea. That increases the cornea?s optical power so that it can refract (bend) light much more strongly and give clear close to eyesight.

For these circumstances, a different from of laser vision correction cure is considered. The ASLA (Advanced Surface Laser Ablation) technique is used when the LASIK system is considered incompatible for a specific patient, for instance, if the cornea is overly slim or if the corneal topography is irregular or if the corneal face coating (the epithelium) is unstable. ASLA can be used for correction of myopia or astigmatism, but it is not used for correcting hypermetropia. An eye expert will be able to determine which method is the most suitable for a particular eye state.

The Most Effective Vision Impairment Solution

Migraine, eyestrain, inability to focus are ordinary symptoms of visual impairment; and an appointment to the eye specialist is recommended. Folks who sit at a desk eight hours a day may eventually suffer astigmatism from consistently hurting the eyes at the computer. Astigmatism is a familiar condition which can either be inborn or result from poor work habits and posture. Used to amend improper corneal curvature, astigmatism LASIK surgery can effectively bring back 20/20 vision in majority of cases. Laser in-situ keratomileusis, or LASIK, is a complex but effective procedure for fixing nearsightedness, farsightedness and astigmatism, or hazy vision caused by asymmetrical curvatures in the surface of the cornea.

Lasik Eye Review

Lasik Surgery: About
What is Lasik surgery?

Lasik is a type of refractive surgery for correcting myopia, hyperopia, and astigmatism. LASIK is performed by ophthalmologists using a laser. The eye surgery is generally preferred to photorefractive keratectomy, PRK, because it requires less time for the patient’s recovery, and the patient feels less pain overall. However, there are special instances where a PRK procedure is medically justified as being a better alternative to LASIK. Many people choose lasik to replace glasses or contact lenses.

New advances in LASIK technology, including Wavefront Lasik, give patients options that provide a level of safety and accuracy than wasn’t possible in the past. With the debut of the technologically advanced lasers, patients can undergo a bladeless form of LASIK. Another advance in Lasik surgery is offering patients personalized forms of vision correction. With the custom LASIK systems, almost all types of vision can be fixed instead of in the past when only a few procedures were able to corrected. This allows patients to achieve better visual results than they would with previous LASIK surgeries.

Before surgery there are several rules the patient must follow to guarantee success. Patients wearing contact lenses are instructed to stop wearing them 4 to 19 days before surgery. During a pre-surgery appointment the surgeon will examine the eye with a pachymeter to determine their thickness, and with a topographer to measure the counter of the eye surface. The operation is performed with the patient awake and mobile; however, the patient is sometimes given a mild sedative and anesthetic eye drops. The procedure itself is performed in three steps. The first step is to create a flap of corneal tissue. The second step is remodeling of the cornea underneath the flap with the laser. Finally, the flap is repositioned. The surgeon then creates a thin flap on the eye, folding it to enable remodeling of the tissue beneath with a laser. The flap is repositioned and the eye is left to heal in the postoperative period.

Post-surgery patients are usually given antibiotic and anti-inflammatory eye drops. These are continued in the weeks following surgery. Patients are usually told to sleep more and are also given a dark pair of sunglasses to protect their eyes from bright lights and protective goggles to prevent rubbing of the eyes when asleep and to reduce dry eyes. They also are required to moisturize the eyes with preservative-free tears and follow directions for prescription drops. It is also normally requested that the patients do not drive, and they find other arrangements to go home.

A candidate for any type of eye surgery must meet a few general pre-requisites. Patients should be at least 18 years old (and often times at least 25 years of age), demonstrate no change in eye sight for at least one year, and as with most surgeries have realistic expectations regarding the results of eye surgery. Patients who have experienced an eye infection or injury in the past year should not undergo the surgery. In the end this is something that only a doctor can decide. Normally, if you meet these requirements listed above you will be accepted.

A Concise Idea Of LASIK Eye Surgery

LASIK is a mode of surgery executed basically on the corneal (the transparent external stratum of the eyeball) part of the eye. Long before LASIK (Laser-Assisted in Situ Keratomileusis) surgery was accepted, many types of eye surgery are being discerned and experimented by surgeons to repair certain eye defects and problems. The system of LASIK was discovered way back in the 1950?s by a Columbia-based Spanish Ophthalmologist. The incessant studies, research and experiment regarding this procedure has brought transformation and a huge step in advance for the advancement of information and discovery of other methods like RK (radial keratotomy), wavefront-guided PRK and the new intraocular lenses. This technology is also now applied in Astigmatism Surgery.

Here?s a rough idea of Lasik Eye Surgery for better perception: LASIK (Corneal surgery), is an irreversible eye operation that is essentially carried out to correct Myopia (near sightedness), Hyperopia (far sightedness) and Astigmatism (abnormal curvature of the eye lens). It is performed by an Ophthalmologist after several tests in able to verify if the client is a candidate for the surgery. For many patients, LASIK is a fair alternative to prevent the use of contact lenses and/or eyeglasses since all of them are for the purpose of correcting eye problem.

Looking At Lasik Eye Surgery Cost

Among the most important worries that eye surgery candidates have is lasik eye surgery cost. If you have looked into the actual procedure of lasik surgery and believe the procedure may be best for you, you should certainly talk to your lasik surgeon to find out about payment alternatives once you come to a decision to have the operation. There could also be a lasik eye center or two in your area that may specialize in inexpensive surgery, so make certain you are acquainted with all the details before you schedule your surgery.

The first thing you should be aware of is that lasik surgery may be elective. Since you may not necessarily need the procedure in order to keep your vision, the surgery is deemed ‘cosmetic’, which is not covered by the majority of health insurance companies. This means you will need to come up with the funds for your surgery on your own, given that you will not be in receipt of a co-pay from your health insurance. It may be useful to open a savings account that will help you to save up the money you need for the surgery, since it can be costly. Depending on the lasik clinic you attend, you can currently expect to spend $1500-$3000 per eye on your eye surgery, but it possibly will be more depending on the locality of the clinic and the prices the doctor has fixed. Normally, your lasik surgeon can help you to establish a payment plan so that you can pay the balance of your lasik surgery cost in increments.

Even when you make a decision that you want lasik surgery, your doctor will in all likelihood tell you about the lasik eye surgery cost you can expect, and will perhaps suggest using contacts and/or glasses as your first choice for vision improvement. You may also be given information about alternate types of surgery that are cheaper than lasik, but might be just as effective for treating your eyes. Your doctor should also inform you that your vision may get better by considering a few lifestyle changes, as for example staying out of the sun without protection for your eyes, or possibly a change in diet, or perhaps supplements which are beneficial to eye health.

Your eyes should be thoroughly assess before you go into surgery, and if you are near-sighted or far-sighted, your physician may help you to determine lasik eye surgery cost by seeing if lasik surgery is the unqualified best answer for you, since these conditions are not necessarily an indication that your eyes are unhealthy. After your assessment and a thorough inspection of your budget, you can reach an informed decision on the lasik surgery that is most appropriate for you. It may well be useful to read articles online from several sources on the topic of lasik prices, as each may provide additional information.

Titles: Learn More About Lutein And Low Vision

Fruits and vegetables have another disease-fighting weapon to offer: Lutein. Studies show this carotenoid prevents and, to some extent, reverses vision loss, immune system problems, cancer and cardiovascular disease. With that in mind, load up your plate with foods high in lutein — carrots, corn, kale, spinach, Swiss chard, collard, mustard greens, red peppers, dill, parsley, romaine lettuce, tomatoes, potatoes and red, blue and purple fruits.

Is your vision blurred? I know mine is after sitting in front of the television for a while. In that case, you and I need to eat more lutein-rich foods. A few weeks after consuming more lutein-rich foods or lutein supplements, some normal-sighted people report less glare, improved color vision and sharper vision. This suggests that lutein and its companion carotenoid zeaanthin may save our sight by acting as a shield or filter that helps to absorb harmful light and dangerous molecules, both of which threaten the retinal tissue. Using products for macular degeneration or specialized low vision aids together with lutein helps the most.

Though everyone’s sight could benefit from a diet high in lutein, it can literally save the sight of those who have family histories of macular degeneration and other vision loss problems. If someone in your family has experienced vision loss of sight at an old age, then your high-lutein diet should start long before you reach middle age. In a Houston University study, women with diets high in lutein and zeaxanthin experienced a 19 percent reduced risk of cataracts, while men reduced their risk by 22 percent.

A dietary intake of only six milligrams of lutein per day decreases your chances of developing age-related macular degeneration by 38 percent. Everyone over the age of 50 should be taking lutein supplements. However, if you are already experiencing macular degeneration or other vision problems, a high-lutein diet can still help you save your sight by increasing the density of your macular pigment. Macular degeneration may be stabilized or reversed with nutritional intervention, He later goes on to say, By far, lutein is the number one nutritional treatment for the disease.

Not only will lutein save your sight, it may also boost your immune system and, accordingly, prevent cancer. Healthy people seeking to boost overall immune function should consider consuming 5,000 IU of beta-carotene daily, along with other carotenoids, such as lycopene and lutein. By boosting your immunity, lutein decreases your chances of getting cancer, since development of cancer as a disease is associated with immune system impairment. I know you’ve probably heard this a million times, but just in case you haven’t, I’ll say it again: We all have cancer cells. Cancer cells develop in our bodies all the time, but our immune systems normally remove the malignant cells before they can develop into the symptoms we call cancer. In addition to boosting your immune system, lutein may also fight cancer by both protecting your cells from free radical damage and increasing cell-to-cell communication, thus preventing them from turning malignant.

However lutein prevents cancer, we know it works. People with high-lutein diets at any age decreased their chances of developing colon cancer; additionally, young people with high-lutein diets decreased their chances. Studies show that a diet high in lutein will also decrease your chances of other cancers, including cancers of the lung and breast. Women who have low levels of lutein have a 2.08-fold increased risk of breast cancer, so not eating enough lutein-rich foods can actually harm you.

It’s easy to add more lutein to your diet because it’s found in so many foods. Just refer back to the list you read above. In addition, lutein is seven times more available from vegetables than beta-carotene, Just adding a few more fruits and vegetables to your plate each day may save your sight, boost your immune system, prevent you from developing cancer and reduce your chances of having a heart attack.

Titles:Investigate More About Floaters And The Low Vision Eye

Imagine staring at your television screen and suddenly a squiggly line drifts into your field of vision. When you try to get a closer look at it, it moves away as if it knows you’re trying to see it better. What was that? you might wonder. As far as vision problems go, this can seem pretty disturbing.

Actually, such lines are known as eye floaters ? they’re in fact fairly common and generally not harmful. Surprisingly, doctors haven’t come up with an medical term for them; they call them eye floaters, too. Once you get used to floaters and realize they rarely affect eyesight in a harmful way, they can become easier to ignore.

But for some people, floaters can be quite annoying. “Not a week goes by that a patient doesn’t call us wanting to rush into a clinic and see us because they’re seeing eye floaters,” says an ophthalmologist at the Portland Eye Center at the University of Oregon State.

And while seeing eye floaters isn’t a reason to panic, in some cases, you’d be right to call your doctor; Eye floaters can also be a symptom of a more serious eye condition. Also, inquiring about low vision aids or products for macular degeneration would be something to look into.

Your eye is filled with a transparent jellylike substance called vitreous humor. Light bounces off your vitreous humor and enters your eye through the pupil. The light then passes through your lens, which focuses the image on your retina. Your retina helps send this information on to your brain to process.

Sometimes stringy clumps of cell fragments can develop and float around in the vitreous humor. If a floater gets in the way of the light coming into your eye, it will cast a shadow onto your retina, which you then see. As you get older, floaters tend to become more common. According to the institute, they’re also more common in people with severe nearsightedness or diabetes.

Your eyesight is nothing to take for granted. But rest assured, most cases of eye floaters are no big deal ? if you’re not sure if you should see your eye doctor about floaters, give their office a call to ask about your particular case.

Your eyesight is not to take for granted. Rest assured, most cases of floaters are not life changing.
