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.

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.

Glucoma side effects?

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 is Pre-Glaucoma?

It is nothing but glaucoma prefixed with "PRE"

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.

How does glaucoma work?

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.

How does glaucoma lead to blindness even thoough accumulation of fluid occurs in the anterior chamber?

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.

Can cholesterol drugs cause glaucoma?

Cholesterol-lowering medications, such as statins, have not been directly linked to causing glaucoma. Some studies suggest that statins may even have a protective effect against certain eye conditions. However, the relationship between cholesterol drugs and glaucoma is not fully understood, and more research is needed. If you have concerns about eye health and medication, it's best to consult with a healthcare professional.

What laser is used to treat closed-angle glaucoma?

Glaucoma laser treatment is used when there is a history of worsening glaucoma because topical solutions have not worked. Medicated eye drops are used to reduce eye pressure, but when the results are not sufficient laser treatment is the alternative.

What is the best thing to take for glaucoma?

The best treatment for glaucoma typically includes prescription eye drops that lower intraocular pressure, such as prostaglandin analogs or beta-blockers. In some cases, oral medications or surgical options may be recommended. It's important for individuals with glaucoma to work closely with their eye care professionals to determine the most effective treatment plan tailored to their specific condition. Regular monitoring and adherence to the prescribed regimen are crucial for managing the disease effectively.

How does glaucoma affect the body?

If by the word "effects" you mean symptoms, then as an eye doctor, I can tell you that the vast majority of patients with glaucoma have no symptoms at all. They would never know they had glaucoma without having their Optometrist or Ophthalmologist tell them! Primary open angle glaucoma is fairly common and the best definition I can give you is this: glaucoma is a chronic, insidious,and progressive optic nerve degeneration which is usually caused by abnormally high intraocular pressure (usually over 20); this progressive damage to the optic nerve very slowly causes thinning of the nerve fiber layer, increased cupping or atrophy of the nerve head, eventually loss of peripheral vision or blind spots, and it can cause complete blindness if not treated. With the advent of scanning laser technology, digital photography of the optic nerve, and sequential scanning optic nerve topography (HRT)in the last 10 years, eye doctors have become much better at diagnosing glaucoma. As time passes and we get a better handle on what glaucoma is and what it does, we are finging that there are many people out there who really do have glaucoma even though their eye pressures are normal. On the other side, there are many people who have documented high eye pressures who never go on to develop classic glaucomatous optic nerve atrophy. So, with that said, it is crazy to treat every patient for glaucoma who has high pressures and it is crazy to just assume that everyone with normal eye pressures does not have glaucoma. It takes knowledge, experience, skill, good equipment, good vision, and even a little luck to be an eye doctor and properly handle those patients diagnosed as "glaucoma suspects". Closed angle glaucoma (or angle closure glaucoma) is very rare and definitely has some symptoms - often severe symptoms. If the fluid-filled chamber between the cornea becomes very narrow and actually closes down so the fluid cannot drain out, then the eye pressure goes up extremely high (usually over 50). The acutely high pressure causes corneal swelling, very hazy vision, halos around lights, very red eye, very painful eye, very hard eye. It is not unusual for the eye pain to be so severe that you then have nausea and vomitting. This kind of glaucoma can result in a blind eye within a few days if not treated properly whereas open angle glaucoma takes many years (untreated) to result in a blind eye. Important note: only an eye doctor can diagnose and treat open angle and closed angle glaucoma. Your family doctor cannot. The emergency room doctor or PA cannot. Only Optometrists and Ophthalmologists have the training and equipment to measure your eye pressures and look at your optic nerves to diagnose glaucoma. Both open angle glaucoma and closed angle glaucoma are more common in elderly patients. In fact, all types of glaucoma are quite rare in patients under age 40. Yes, there are at least 7 different types or sub-types of glaucoma. Treatments for glaucoma in the year 2007 are very good!! There are lots of different medicines, delivered as eyedrops, to treat glaucoma and most are very effective. I have been in practice now for 16 years and I have had only 3 patients who went completely blind from glaucoma and that was because they came to me already blind and asked, "hey doc, I can't see, what do I do?" They had a type of glaucoma called neovascular glaucoma either as a complication of their poorly controlled diabetes or lack of blood flow through the carotid artery and ophthalmic artery. Very sad!! It could have been treated if they had just come to me 3 or 4 years earlier. Moral of the story: "don't be stupid and take your eyes and vision for granted; get a yearly eye exam even if you think you see fine."

Are I-Caps good for glaucoma patients?

I-Caps, which are multivitamins designed for eye health, may provide some benefits for glaucoma patients by supporting overall eye health with essential nutrients. However, they should not replace prescribed glaucoma treatments or medications. It's important for glaucoma patients to consult with their eye care provider before adding any supplements to their regimen, as individual needs may vary.
