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.

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

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?

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

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

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

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

My doctor wants to treat me for suspect glaucoma based solely on oct scan. I passed all other glaucoma tests. Is treatment appropriate?

Probably not. : Only 1 abnormal oct test doesn't make a diagnosis that indicates treatment. Depending on the findings, may be false positive or glaucoma suspect--observe category. ...Read more

How do you know if you are at risk for glaucoma?

How do you know if you are at risk for glaucoma?

Genetics and age: The two largest factors contributing to the development of glaucoma are age and genetics. Other than that, trauma, steroid usage, anatomical conditions (narrow angles, pseudoexfoliation syndrome, pigmentary dispersion syndrome of the iris, cataracts), prior surgery, can all cause glaucoma. You need to be examined and discuss with an eye md. The biggest risk factor for glaucoma is genetics. ...Read more

What does it mean glaucoma suspect / ON Cupping. Location. OD OS?

Optic nerve eval: Glaucoma suspect is a term applied to individuals that have risk factors for glaucoma (thin cornea, above normal eye pressure, positive family history of the disease) & may have subtle optic nerve changes that are NOT causing structural optic nerve damage or functional vision loss. There are many millions of people that are suspects & are monitored. Only fraction develop disease. (OD=rt, OS=lt). ...Read more

Is laser surgery effective in treating glaucoma?

Yes: Yes it works well in many glaucoma patients. There is four laser treatments that are used for glaucoma. Slt and alt used to lower the pressure by increasing the outflow drainage, ciliary body ablation will decrease the ciliary body which produces the fluid inside the eye (and treatment slows the production, lowering the pressure). Laser peripheral iridotomy prevents of treats angle closure. ...Read more
