Glaucoma is not a single disease, but a group of eye diseases that have one feature in common: progressive damage to the optic nerve caused by increased pressure within the eyeball. The pressure comes from a clear fluid called the aqueous humor. This fluid helps to nourish the eye, and flows in and out of the eye through a mesh-like channel.<br/><br/> In people with glaucoma, the fluid does not drain properly and pressure builds up in the eye, damaging the nerve that transmits images to the brain. As this deterioration of the optic nerve continues, vision worsens, and eventually, blindness can result.<br/><br/>

I have Myopia.
I'm on medical treatment for Glaucoma (Cosopt eye drops twice/day for both eyes).
Anterior segment examination showed Nystagmus.
He did Visual Field twice and the results were normal.

On examination best corrected visual acuity 0.2 (OD) & 0.3 (OS),

My Refraction:
is (-9.0/-1.50@120)(OD), (-8.5/-1.0@50)(OS).

Can i do IOL or not???
Dr. Edward Rockwood:
Most patients having cataract surgery can have a lens implant placed successfully.
JBG5162:
Hi - thanks for taking my question!  Are there different types of Glaucoma?  If so, are there different treatments for each?
Dr. Edward Rockwood:
The biggest two categories of glaucoma are open angle and angle closure.  Angle closure glaucoma can come on suddenly and requires a laser opening in the iris.  
rhs123pal:
are there oral medications that are effective--my timolol and xalatan eye drops cause intense itching.
Dr. Edward Rockwood:
There are two:  methazolamide and acetzolamide.  However these two can cause an allergic reaction.

Hi I am a 14 year old female.I got my glasses last year.I am nearsighted.Last year my vision was 70/20 in both eyes,maybe two months ago I went to the eye doctor my vision with my old glasses was 20/20 in both eyes.I spend maybe five hours on the computer every day.I feel like my vision is getting worse again.will my vision fix itself if I eat a lot of carrots and spend less time on the computer.  Why did my vision change so much?
Dr. Edward Rockwood:
It is not unusual for nearsightedness to get progressively worse from childhood until about age 20.  You may need new glasses or contact lenses.
Dr. Edward Rockwood:
Carrots have vitamin A which has been proven beneficial for your eye sight.
Sandy M:
What are the symptoms of Glaucoma?  If someone has glaucoma, are the symptoms always present?  If not, then how would a person know they have Glaucoma, without seeing an eye doctor?
Dr. Edward Rockwood:
Most patients with glaucoma have no symptoms other than a gradual loss of side vision.  Usually there is no pain, unless the pressure is extremely high,
Michael:
Dr. Rockwood, when is surgery the "preferred" treatment for Glaucoma?
Dr. Edward Rockwood:
Surgery is preferred when eye drops and laser cannot control the eye pressure.  
mdebski:
My dad has glaucoma, which i think he got from having high blood pressure.  Does that mean I am at risk, too?
Dr. Edward Rockwood:
High blood pressure does not cause glaucoma.  And glaucoma does not cause high blood pressure.
Pam:
What is the average age for someone to develop glaucoma?  
Dr. Edward Rockwood:
Glaucoma can occur at any age, but tends to increase in frequency as we get older.  However African Americans do tend to get glaucoma at an earlier age than caucasians.
eltuto:
How accurate are eye exams in detecting eye cancer? And at what age are you prone to develop eye cancer?
Dr. Edward Rockwood:
A good dilated retinal examination will detect any eye cancer, a problem which is rather uncommon.
sk123:
What can we do to prevent glaucoma?
Dr. Edward Rockwood:
Generally glaucoma is hereditary and not preventable.  However glaucoma occasionally occurs after severe eye injury which is preventable, or in patients with severe diabetes, which is controllable.
SeatownHero:
I have been taking Beconase nasal spray for 3 months for a deviated septum.  I have read that this medication can cause glaucoma, and would like to know if I should stop using it?
Dr. Edward Rockwood:
Corticosteroids taken by mouth after two weeks can raise your eye pressure.  That is much less likely to happen with a nasal spray.
Quinnh:
Hi doctor, I am interested to know what type of research you are doing on Glaucoma... do you foresee any new procedures coming out in the near future?
Dr. Edward Rockwood:
We occasionally have clinical glaucoma studies, but do not have one at this time.  The Cole Eye Institute will be conducting a clinical study next year, but the details are still being worked out.
Quinnh:
Can glaucoma affect contrast sensitivity?
Dr. Edward Rockwood:
Yes glaucoma can cause a decrease in contrast sensitivity.
Dr. Edward Rockwood:
Contrast sensitivity is your ability to see the contrast in shapes, colors, sizes, etc...
PATTYPATCH:
Dr. Rockwood, Ihad asked earlier about a fluid bubble that has developed on my left eye at the temporal bottom of my eye after having trab surgery. Why does this happen and if corrected, is ist possible for it to recur?
Dr. Edward Rockwood:
Sometimes a procedure can be done to reduce the bleb size.  However if the bleb is removed, your fluid pressure may go very high again.
