All about Glaucoma – Its Tests and Different Treatments

Glaucoma is a type of eye disease that causes damage to the optic nerves which in turn leads to loss of vision that is permanent when left untreated. In most of the cases this condition is caused by the rise in the intraocular pressure of the aqueous humor, which is the fluid in the eye. This deadly condition has earned the nickname of being the “silent thief of sight” as the loss in vision often occurs very gradually and over a period of time and the condition is often identified only in the advanced stages. In most of the cases of glaucoma the loss of vision is so slow that patients only realize that there is a problem when they have completely lost their vision. Glaucoma is in fact one of the second most popular causes for blindness.

There are different types of glaucoma namely, the chronic or open angle glaucoma, the acute glaucoma or the angle closure glaucoma, the congenital glaucoma and the secondary glaucoma. While the open angle glaucoma progresses at a slow rate, the close angle glaucoma often is painful and appears suddenly causing loss of vision quickly. The congenital glaucoma often runs in families and is a condition that is present at birth and the secondary glaucoma is caused due to consumption of certain drugs.

Different Types of Glaucoma, Symptoms and Causes

The human eye has two main areas, known as the anterior segment which is in the front and is filled with the aqueous humor, a clear watery fluid and the posterior segment at the back that is filled with the vitreous humor. The usually intraocular pressure, which is the pressure within the eye, is often between 12mmHg and 20mmHg and usually when the intraocular pressure rises in the eye, it leads to number of complex medical conditions with glaucoma being one of them.

Double Vision – Seeing Double – Causes of Diplopia

What is Diplopia?

Diplopia is also known as Double Vision. It occurs when an individual sees 2 or more images of the same object. Diplopia is different from the blurred vision where a single object appears to be unclear.

The vision in humans is single Binocular vision. This means that the images from both the Eyes are recorded and processed by the Nervous System but it makes a single image. An interruption in this process can make a double vision.

The double vision may be present in 1 Eye known as Monocular or 2 images can be made from both the Eyes together known as Binocular.

Physiological Diplopia

Diplopia can be a normal phenomenon, for example, when focusing on an object that that is close up, another object in the distance can appear double. This is known as Physiological Diplopia. It is generally not noticed because the Brain has the power to suppress these double images.

A thin layer of tears help to keep Eye and vision comfortable. This layer of tears is made up of 3 layers:

The inner most layer is the thinnest and it is a layer of Mucus. Mucus helps keep a watery layer over the Eye.

The middle layer is thick. This layer is a Salt-Water solution. This layer keeps the Eye moist, comfortable; it also drains out the Dust in the Eye.

The upper layer is a thin layer of Lipids. Lipids consist of fats and oil. The function of this layer is to decrease the evaporation of Watery layer.

cataractHere I am going to discuss a very common disease of the eyes and that is famously known as Cataract. First I would like to give you the proper definition of this disease in medical terms ‘it is the clouding that develops in the crystalline lens of eye and it also affects the eye sight’.

Normally you might have seen some person with a blurry type of eye lens just like fog on the glass of window, in the normal routine we can have many names for this problem but the proper medical name is ‘Cataract’. Normally the eye lens tends to be so clear that we can clearly see the inner texture but for a person with this disease, you can see the inner side of eye so clearly.
