Glaucoma
Glaucoma is a group of diseases of the optic nerve involving loss of retinal ganglion cells in a characteristic pattern of optic neuropathy. Although raised intraocular pressure is a significant risk factor for developing glaucoma, there is no set threshold for intraocular pressure that causes glaucoma. One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressures for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.

Does lack of oxygen cause pale skin?
A lack of oxygen will indeed cause pale skin. Pale skin can also be caused by anemia and should always be evaluated by a doctor or medical professional.
What is the pH of vitreous humor and how does it change with diabetes or other retinal disorders?
The vitreous humor of the eye has an average pH of 7.29 which is just slightly alkaline. Diabetes characteristically causes an abnormal growth of blood vessels in the eye which can result in bleeding into the vitreous humor, which will lower the pH (although the pH is not the problem, it is the opacity of the blood which obscures vision).

What to do if individual who is scheduled to begin working does not show up?
Employment is a contract between yourself and an employee. If the person is a "no show" more than three days in a row, the industry practice is that s/he is not employed at your firm. I work in retail and instances like this are very common. Always check references, and consider having "orientation" before putting a new employee on the schedule. Do not hold the job for the person unless circumstances were beyond control such as car failure, jail, or family loss. Even then, the employee should have called. Do not get upset over it, just accept this occurance as a natural part of doing business in today's society.
What is an aneursym behind the eye?
An aneurysm is a buldge in a blood vessel. When this occurs in the back of the eye (on the retina) it can be seen by your eye doctor. It can be from many sources but most commonly its from diabetes. Your eye doctor may choose to photograph it so they can monitor it over time to see if it is getting worse or if it is minor, just choose to monitor it.
There are many things that could happen if you have glaucoma. Some of these things include trouble adjusting to darkness, difficulty focusing, double vision, and watery eyes.
What are the side effects of peripheral vasodilators?
Peripheral vasodilators may cause dizziness and orthostatic hypotension--a rapid lowering of blood pressure when the patient stands up in the morning.
Why would your right eye tear up more than your left eye when wind blows in your face?
You could have a clogged or occluded nasolacrimal duct. The tears are produced by the lacrimal glands on the upper/outer area of the eye, wash across the eyeball and go into the small hole on the inner aspect of the lower eyelid. This is the opening for the nasolacrimal duct which carries the tears into the nose. If it becomes blocked for any reason the tears have nowhere to go except down your cheek. It can be flushed out by an ENT doctor.
What are some benefits of using eye drops?
Some benefits of using eye drops are prevention of itching and dryness. Eye drops are also used in treatment of different eye problems, such as glaucoma.
Glaucoma is usually associated with an increase in the pressure inside the eye. This increase occurs in front of the iris in a fluid called the aqueous humor.
What conditions can be worsened by cholesterol-reducing drugs?
Cholesterol-reducing drugs may make some medical problems worse. Before using these drugs, people with any of these medical conditions should make sure their physicians are aware of their conditions:
How long does a person who has glaucoma live?
Untreated glaucoma can cause blindness, but it's not itself directly fatal. Someone with glaucoma will live, on average, about as long as they would have if they'd gone blind from some other cause.
Is glaucoma always sudden in onset?
No, glaucoma is not always sudden in onset. While acute angle-closure glaucoma can present suddenly with severe symptoms, most cases, such as primary open-angle glaucoma, develop gradually and may not show noticeable symptoms until significant damage has occurred. Regular eye exams are essential for early detection and management of glaucoma, regardless of its onset type.
Glaucoma leads to blindness primarily due to increased intraocular pressure (IOP) resulting from fluid accumulation in the anterior chamber, which can damage the optic nerve. This damage disrupts the transmission of visual information from the eye to the brain. Over time, the pressure can cause irreversible loss of retinal ganglion cells, leading to vision loss and, if untreated, complete blindness. The condition often progresses without noticeable symptoms until significant damage has occurred, making regular eye examinations crucial for early detection.
