Common Eye DiseasesPeople often overlook the blessing of healthy eyes but for some people it is as important as the health of heart or any other body organ that is indispensible for life. Some of eye diseases can even shut down your window to the beauty of the world, nature, flora and fauna. Here are the top four eye disorders that need to be kept under control to prevent them:

Glaucoma:

Human eye produces a small amount of limpid fluid within the eyeball between the cornea and the lens. An equal amount of this fluid pours out of our eye continuously. If someone has a glaucoma disorder, then this fluid does not drizzle out of the eye properly. The stoppage of the fluid builds up pressure inside the eye by restricting the blood flow. It damages the optic nerve fibers and the disease gets even worse over time. This damage causes dark spots in the eyeball that can lead to perpetual blindness.

It damages the optic nerve fibers and the disease gets even worse over time. This damage causes dark spots in the eyeball that can lead to perpetual blindness. Modern surgery helps people to say good bye to Glaucoma. The operation takes about ten minutes and doctors use special instruments.

Types of Glaucoma:

  • Open-Angle Glaucoma

    It is the most common type of glaucoma. In this type of eye disorder, fluid does not flow properly in the channel of the eye, however, the shape of the eye remains unchanged. This condition is known as trabecular meshwork.

  • Angle-Closure Glaucoma

    Although the angle-closure glaucoma is not a very common type of glaucoma yet, when it strikes, it exerts sudden pressure within the eye. As a result, the passage between the iris and the cornea becomes extremely narrow and blocks the fluid within eyeball.

Symptoms of Glaucoma

  • Blurred vision
  • Eyes become sensitive to bright light
  • Weak night vision

Diabetic Retinopathy:

Diabetic retinopathy is considered one of the primary reasons of blindness in adults around the world. It is a frightening eye complication that affects the blood system of the retina. In this particular eye disorder, the blood vessels well and fluid gets leaked. Even in some cases, new and unusual vessels are developed on the retina surface.

In initial stage of diabetic retinopathy, it is less likely to affect vision but with a passage of time diabetic retinopathy becomes intense and eventually causes vision loss. This diabetic related eye disorder usually affects both eyes at a time.

Symptoms of diabetic retinopathy:

  • Sudden changes in eyesight
  • Weak night vision
  • Double vision
  • Blurred vision
  • Seeing black spots

Cataracts:

In a normal human eye, light travels across the lens before it goes to the retina where it is focused. However, in a case of cataracts, the eye lens becomes hazy and unclear and does not allow light to be focused on the retina. The outcome of this is a blur image that sometime completely rescinds human vision. Usually, cataracts is related to the age and with time, the eye lenses turn out to be thicker and less vibrant.

Symptoms of Cataracts:

  • Weak night vision
  • Hazy vision
  • Double vision
  • Difficulty in reading

Age-Related Macular Degeneration:

Age-related macular degeneration, often called AMD, is a somatic disorder that affects the macula of retina. It is integral part of the eye and supports our vision to focus during reading and performing other actions that need sharp and focused vision.

In the initial stages, AMD is not usually easy to be noticed. It can only be detected through a dilated eye examination. However, AMD weakens the capability of vision cells, which carry nourishment to the macula, in course of time.

Types of AMD:

  • Dry Macular Degeneration:

    It is the main one among the two types of AMD and nearly 90% of people who have this disease are suffering from this type of the disease. Dry macular degeneration deteriorates vision by developing blind spot in the center of the eyeball. It breaks down the layers of somatic cell in the macula that brings about a blurry vision.

  • Wet Macular Degeneration:

    Wet macular degeneration is also called exudative AMD. It is not very common but when it happens, it is very likely to lead to the complete visual loss over a short period of time; sometimes just months. It is a long-lasting eye disorder. Wet macular degeneration is often triggered by development of unusual blood vessels that leak fluid and blood into the macula.

Symptoms of AMD

  • Distortion of straight lines
  • Blurry vision
  • A dark spot in the central point of eye
