Glaucoma (Overview)

A condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked to a buildup of pressure inside your eye. Without treatment, glaucoma can cause total permanent blindness within a few years.

Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?

Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity.

What eye drops combat glaucoma?

What eye drops combat glaucoma?

Medications: Several classes of medications are prescribed for treating glaucoma. These include: prostaglandin analogues, alpha adrenergic agonists, beta adrenergic antagonists, carbonic anhyrase inhibitors, cholinergic agonists, & hyperosmolar agents. In development are rhokinase inhibitors. Laser and incisional surgical treatments are also options. Primarily though, glaucoma is treated with eye drops. ...Read more

Is glaucoma inherited?

Is glaucoma inherited?

Some are: There are many different types of glaucoma, some caused secondarily through trauma or other diseases. But there are some type of glaucoma where genetics are involved but not 100%. In other words just because your parents have it doesn't mean you have to get it. However, risk is certainly higher.... ...Read more

How does glaucoma cause eye floaters?

How does glaucoma cause eye floaters?

It does not cause it: Just like within the body there are many parts, although one organ, the eye is very similar with many parts as well. Where floaters occur in the eye is separate from the area where the effects of glaucoma occur, which is the optic nerve. Floaters are typically black spots that appear real like gnats in front of you. Vision loss from glaucoma is like dark patches in vision that don't go away. ...Read more

Which eye drops prevent glaucoma pain?

Which eye drops prevent glaucoma pain?

Glaucoma not painful: If you have glaucoma, and have pain, then the cause is something else than the glaucoma. The only painful glaucoma comes from acute angle closure glaucoma or advanced hemorrhagic glaucoma. The most common glaucomas are painless. If you have pain, discuss this with your ophthalmologist. ...Read more

What are the symptoms of glaucoma?

What are the symptoms of glaucoma?

Depends: Most glaucoma is asymptomatic until end stage disease when the vision is decreased in both eyes. At that point, contrast, acuity, and peripheral vision are diminished. Thus, screening is key if at risk. A particular type called acute angle closure glaucoma with a sudden rise in eye pressure can have symptoms of red eye, severe eye pain, blurred vision, haloes, headache, nausea, vomiting... ...Read more

What are the signs of glaucoma?

Signs & symptoms: There are 2 main types of glaucoma: acute closed-angle and chronic open-angle. Acute glaucoma usually affects one eye, presenting with sudden eye pain, blurred vision, halos seen around light, nausea and vomiting, and a non-reactive dilated pupil. Chronic glaucoma usually is asymptomatic, but can present with gradual loss of vision and headache. Both have increased intraocular pressures. ...Read more

Is glaucoma curable?

No: The answer depends on how you define curable. We don't eliminate glaucoma with today's therapies, and we currently cannot restore vision that is permanently lost due to glaucomatous damage. However, we lower the intraocular pressure through medications, laser, or surgery in order to slow down or halt the rate of glaucoma progression so that you can outlive losing your sight. ...Read more

Can optometrist be relied on to diagnose glaucoma? Said i didn't have it yet but would watch it.  Glaucoma specialist said I have it at moderate stage

No!: Only an ophthalmologist has the training and experience to diagnose, monitor and treat glaucoma. Early glaucoma can be very subtle, and optometrists do not have the medical background or level of experience to distinguish early signs as glaucoma usually presents with no symptoms. ...Read more

Glaucoma is likely an interplay of genetic susceptibility as well as aging and other factors especially since there are many types. ...Read more

What are the necessary steps taken for the early stages of glaucoma?

Early glaucoma: In early stage glaucoma, baseline testing is done with visual field and sometimes nerve fiber layer scanning. The cup to disc ratio of the optic nerve is noted. Treatment by SLT laser or eye drops attempts to lower the eye pressure about 25%. Patients are checked 3 to 4 times per year. Each year, the testing is repeated. If worse, then treatment must be more aggressive.If not worse, you are OK. ...Read more
