Glaucoma has been called the “sneaky thief of sight.” Victims of this eye disease experience gradual vision loss that may not be recognized until it’s too late. Glaucoma is the second leading cause of blindness worldwide. If your family has a history of glaucoma, you have a 6% chance of developing the disease as well.

Glaucoma Effects

Pressure builds up inside the eye of the glaucoma patient. If treatment is not administered early, the optic nerve is damaged and vision begins to fade resulting in blindness.

Glaucoma Types

There are several types of glaucoma.

Open-angle glaucoma is the most common form of the disease and heredity is the most common factor.

· Open-angle glaucoma is caused by pressure build-up due to clogged drainage canals of the eye preventing fluid to flow out of the eye.

· Vision loss is gradual and can be treated with medication if caught early.

· It is vital that people over 40 have regular eye exams to measure intra-ocular eye pressure, especially if your parents or siblings have the disease.

Angle-closure glaucoma can progress gradually or suddenly. The iris blocks the drainage canals causing blurred vision, “rainbows” around lights, eye pain, headaches and nausea. Surgery relieves fluid trapped within the eye resulting in a long term or permanent solution. Other symptoms include the following:

· Halos, blurry or cloudy vision

· Vision decreases

· Severe eye pain

· Extreme sensitivity to light

· Excessive blinking and runny eye

· Crossed or out-turned eyes

· One eye becoming larger than the other

· Nausea, headache



Normal tension glaucoma can be treated with surgery or medication.

· The patient’s eye pressure is normal but the optic nerve is damaged.

· Cardiovascular disease can increase the risk of this form of glaucoma.

Congenital glaucoma occurs in babies when the eye doesn’t develop properly in uterine.

Secondary glaucoma is caused by disease, injury or other eye problems.

Other Risk Factors for Glaucoma

Anyone is susceptible to losing his or her eyesight from this devastating disease. Heredity plays a big role but there are other common factors that elevate risk.



High blood pressure

Low blood pressure for people 60 and over



Race:

· African Americans 40 and over – glaucoma is the leading cause of blindness

· Hispanics 60 and over have a higher risk of open angle glaucoma

· Asian & Eskimo descent have a higher risk of closed angle glaucoma

· Japanese Americans have a higher risk of normal tension glaucoma

Age

· Risk rises significantly for people aged 40 and over

· 60 and over are 6-times more likely than others to develop glaucoma



Diabetes – doubles the risk



Injuries

· Dislocated lens retinal detachment

· Eye tumor

Eye problems

· Myopia – extreme nearsightedness

· Hyperopia – extreme farsightedness

· Thin corneas



Steroid use

Medical advancement has improved the precision and safety of traditional Lasik. It has also made room for other forms of Lasik. Patients who find they do not meet the ideal standards as a candidate for Lasik have other options. Lasik eye surgery can now accommodate a variety of needs for vision correction. Learn about how to improve your night vision with Lasik.

Traditional Lasik

Lasik is the preferred procedure for many Americans with nearsightedness, farsightedness and astigmatism. An outpatient procedure that usually takes about 15 minutes, Lasik is performed with a microkeratome blade. The laser eye surgeon creates a flap in the outermost corneal layer. An excimer laser reshapes the cornea, and the flap is then replaced as a natural bandage.

Low Order Aberrations Vs. High Order Aberrations

Lasik is a simple procedure, but many patients have vision correction needs that traditional Lasik is not designed to address. Traditional Lasik is most beneficial to patients with low-order aberrations. Refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism are low-order aberrations that can be corrected with traditional Lasik.

Improve Night Vision With Custom Lasik Surgery

Custom Lasik addresses not only low-order aberrations, but also more complex, difficult-to-detect aberrations. Patients with large pupils, low contrast sensitivity and thin corneas may be able to improve night vision through Custom Lasik. Low-contrast sensitivity is a high order aberration which makes it difficult to see an object against a low-contrast background. People with large pupils are not only prone to poor night vision, but traditional Lasik can also worsen the aberration.

Custom Lasik, Custom Results

Custom Lasik uses wavefront technology to pinpoint refractive errors that are undetectable through traditional Lasik. Wavefront technology creates three-dimensional chart of the cornea, measuring how your eye focuses light. Custom Lasik corrects visual acuity, as well as, visual quality. Lasers guided through wavefront technology are more precise and individualized for each patient.

Custom Lasik may also be the best option for patients with previous laser eye surgery. Custom Lasik can be the answer for correcting past laser eye surgery, with unsuccessful results. Patients who experience complications from traditional Lasik, such as light sensitivity, night glare and halos, may find relief through Custom Lasik.

Lasik Cost

The cost of Lasik surgery can range anywhere from $499 to $2,500. Cost is determined based on the type of Lasik surgery and the condition of your eyes. When making a decision about which type of laser eye surgery will work best with your needs and budget, keep in mind any conditions that may increase the risk of postoperative complications associated with traditional Lasik. Custom Lasik is the most expensive for of Lasik surgery, but may also prevent the need for additional surgeries. If you’re looking specifically to improve night vision, Custom Lasik may be the best route to take.

Because Lasik is considered an elective procedure, most insurance companies will not cover the cost. However, there are many financing options available. Your Lasik surgeon may provide a payment plan. He or she may also work with a few financial institutions. In this case, you may be able to take care of the application process directly at the doctor’s office.

Finding macular degeneration treatment s. Vision problems due to the onset of macular degeneration are quite prevalent, especially in the elderly. Macular degeneration occurs when the macula, located in the central portion of the retina in the eye, becomes weakened or damaged. The result is a loss of central vision. Central vision is used to read and drive, so it is crucial to save as much of a patient’s vision as possible as soon as possible. Although this medical condition has no cure at this time, there are some promising new macular degeneration treatments that have shown to alleviate and slow down some of the symptoms of age-related macular degeneration.

There is a range of vision loss that can occur depending on the severity and type of age-related macular degeneration a patient has. Because it affects the macula located in the center of the retina, a patient’s peripheral vision is usually not adversely affected by the condition. With the onset of the condition, a patient’s vision might still be quite good, but the situation can worsen over time. There are two different types of age-related macular degeneration that often result in the greatest loss of central vision, and they are called wet and dry. The dry form of advanced macular degeneration is caused by the reduction of the rods and cones located in the retina, while wet advanced macular degeneration occurs due to leakage of excessive blood vessels and the resulting scarring under the macula.

One thing that retinal specialists might tell their patients with macular degeneration is to take certain vitamins as part of a spectrum of macular degeneration treatment s. Patients in the initial onset stages of this condition sometimes benefit from taking vitamins C, E, zinc, lutein, zeaxanthin and eating foods that are high in beta-carotenes, such as dark green leafy vegetables, corn and peas.

Another macular degeneration treatment can be found in cholesterol reducing drugs. People in the early stages of this medical condition often develop drusen, or yellow deposits, in the macula. The development and increase in the number of drusen seems to be related to the patient’s cholesterol level, with drusen more prevalent in those with higher cholesterol. Medications, such as statins, which reduce cholesterol, and aspirin, which reduces inflammation, may have a significant impact on reducing the size and number of drusen in the macula and thus lessen the chances of someone developing age-related macular degeneration.

A couple of wet advanced macular degeneration treatments, Macugen and Lucentis, have been approved by the FDA. Macugen is useful because it helps to reduce the number of excessive blood vessels that can grow under the retina. These can become inflamed and eventually burst, causing vision problems. Lucentis also reduces the growth of too many blood vessels. Lucentis is administered as an injection under the eye, and offers a great new treatment option for some patients with these kinds of vision problems.

The future is looking brighter with these emerging new macular degeneration treatments.
