Glaucoma is a condition where high eye pressure damages the optic nerve inside the eye
Below is a series of images showing normal (left side) to slightly thin (center) to absent (right) optic nerve rim tissue
Many people come in for their first eye exam and we see an optic nerve which looks like the middle picture below
In these cases we do not know if it used to look like the normal optic nerve and glaucoma has caused it to change
Or if it has always looked like that and there is no problem with glaucoma
For this reason we need to monitor for changes over time in mild or borderline cases of glaucoma
Optic nerve damage from glaucoma cannot be reversed (there is no cure for glaucoma) but we can lower the eye pressure and prevent further damage
When there is damage to the optic nerve, the eye will progressively and often very slowly lose its side (peripheral) vision
If left untreated, glaucoma can lead to complete blindness of the eye
Treatments include eye drops that you take each night, forever
The eye drops do not cure glaucoma, but they prevent glaucoma from worsening
If you stop taking the drops for glaucoma, your glaucoma will worsen
Other treatments include laser treatments, minimally invasive glaucoma surgery (performed during cataract surgery) or other glaucoma surgeries (for more advanced cases)
Glaucoma tends to move slowly; most cases are not emergencies, but this is something that you do not want to ignore
My office does not have the advanced technology to manage glaucoma

The angle of the eye is the intersection of the inner curve of the cornea and the colored iris inside your eye
If there is not enough space in the angle, fluids in the eye can be blocked from flowing out through the angle, which can cause eye pressure to increase
In some cases the eye pressure can increase to very dangerous levels
This can lead to peripheral vision loss from glaucoma
This can be prevented with a laser treatment or cataract surgery
Your medical insurance will pay for these treatments

Narrow angles are a risk factor for glaucoma which can cause permanent vision loss over time
Narrow angles can be treated with a simple laser procedure
Optic nerve abnormalities consistent with glaucoma but with no visual field abnormalities
Optic nerve abnormalities consistent with glaucoma, plus visual field abnormalities in one hemifield, but not within 5 degrees of fixation
Optic nerve abnormalities consistent with glaucoma, glaucomatous visual field abnormalities in both hemifields, and/or vision loss within 5 degrees of fixation
