History of the Disease
The disease has been known for centuries dating back to
the ancient Greek civilization
The Greek philosopher Hippocrates describe how
blindness often occurred in more elderly people, whichhe called glaucosis

History of the Disease
Despite its discover many centuries prior, scientists were
only able to understand and identify the disease in 1851
through the invention of the Ophthalmoscope by
Hermann Von Helmholtz

What is Glaucoma?
Glaucoma is the term used to describe a network of
vision related disease that result from damage to the
optic nerve that causes vision loss and even blindness

What is Glaucoma
Two of the most common types of glaucoma include:
Primary Open Angle Glaucoma and Primary Angle
Closure Glaucoma
Despite their different names, they are almost identicalin their causes and symptoms
Primary Open Angle Glaucoma Primary Angle Closure Glaucoma

Causes of Glaucoma
Glaucoma is often attributed to an increase in the
intraocular pressure in the eyes
The normal IOP for humans is 14-16 mmHg
Whereas, in people with glaucoma, the average is at 22mmHg

Causes of Glaucoma
This buildup of pressure can be the result of many
environmental stresses including: sleep apnea, darkness andemotional stress
However, the development of the disease is more commonly
attributed to old age and the inability of certain parts of theeye to function

Causes of Glaucoma
Contemporary research has
shown that there might be a
genetic defect that can cause
glaucoma
In patients with primary
open angle glaucoma,
changes in the DNA
sequence at genes includingCaveolin 1 and 2, as well as
deletions in DNA at genes
including TBK1
Alteration of the serine protein was found to cause glaucoma
in mice

Causes of Glaucoma
Despite their discovery of the genetic
mutations found in many different types of
glaucoma, scientists are still attempting to
discover their significance

Symptoms of Glaucoma
In Open angle glaucoma, there are no
noticeable symptoms until severe vision loss
after the pressure in the eye has accumulated
over time

Symptoms of Glaucoma
In closed angle glaucoma, the most common
symptoms include: hazy or blurred vision,
severe eye and head pain, nausea or vomiting,
and sight loss

Symptoms of Glaucoma
As glaucoma can result in vision loss, it is very hard for
the person with the disease to perform daily activities, as
they cannot see very well, if at all
Also, this disease may be very hard on the patients familyas they have to care for them, as they have a hard time
seeing things

Identification of the Disease
In closed angle glaucoma, the disease is nearly
impossible to notice, as the effects of the disease dont
kick in until many years after the disease is contracted
However, if one were to visit an eye doctor, the doctorwould be able to notice that they have glaucoma

Identification of the Disease
In all other types of glaucoma, the disease is easily
identified, as the symptoms are visible very early in the
development of the disease

Identification of the Disease
Scientists have also found that certain types Glaucoma
are hereditary
If a persons parents were to have had glaucoma, that
person would be 9 times more likely to contract thedisease

Treatments for Glaucoma
Common treatments for glaucoma include eye drops,
pills, and laser surgery
These treatments are all more effective early on in the
diseases development as vision loss is irreversible

Bioethical Considerations
One of the main ethical concerns regarding Glaucoma
lies in the question: to treat or not to treat?
As there is incomplete knowledge regarding the
diagnosis and management of the disease in patients,many of them receive the incorrect treatment, which can
cause great harm to their vision
Therefore, scientists are attempting to get a better
understanding to try and avoid these confusions
