Question 1

are visual field defects present in glaucoma?

Accepted Answer

In advanced glaucoma: Glaucoma is a condition that is related to an increase in eye pressure. Over time, the optic nerve gets damaged and you start to lose peripheral vision (which shows up as field defects). So, initially you may have a normal field, but if left untreated, you will have field defects which are permanent.

Question 2

ideas? what nonprocessive conditions cause a visual field defect?

Accepted Answer

Visual field defect: There are many conditions that cause a visual field defect.    Nonprocessive refers to a biochemical enzyme usage and does not make sense here.

Question 3

can you tell me: are visual field defects always present in glaucoma?

Accepted Answer

Frequently: Changes in the field of vision are one of the hallmarks of the diagnosis of glaucoma.  The aim of treatment is to prevent this from happening and also to prevent it when present from progressing.  Some cases are detected early when other changes hint strongly that glaucoma could be a problem, and so field defects might not have occurred yet in such cases.

Question 4

is there any related color vision problem associated with visual field defects?

Accepted Answer

Depends on cause: There are many causes of vf defects.  Some involve peripheral vision, some more central vision.  If problem in intraocular, color vision can be associated.

Question 5

are visual field defects always present in glaucoma patients?

Accepted Answer

No: The defects occur after the increase pressure in your eye causes permanent damage to your vision.  Usually you lose the peripheral vision.  When it is bad you feel like looking through a tunnel when your peripheral vision is gone.

Question 6

are visual field defects always present in patients with glaucoma?

Accepted Answer

Good question!: Glaucoma is a progressive optic neuropathy.  What that means, is that it continues to get worse and cause more loss of vision.  The visual field defects, once present, only continue to get worse.  That is why the treatment is so important for holding on what you have.

Question 7

am i supposed to see a special consultant opthalmologist for visual field defects?

Accepted Answer

Optimitrist & Eye MD: Usually after a 20-30% reduction, difficulty with eye fatigue and loss of effective night vision is noted.  Believed that excessive hooding to that level forces drivers to lift their head when driving at night, resulting in excessive glare and loss of "gray" colors needed for depth perception.  Use of visual field analysis in most eye doctor offices can measure the degree of loss.

Question 8

is it true that the bigger the visual field defect, the worser the brain has been damaged?

Accepted Answer

Depends: If the area of the brain damaged is the occipital lobe or the optic radiations, then visual field defects can occur.  Generally damage at its maximum occurs immediately and over time there can be a lessening if the areas recover.  Of course, the larger the initial damage, the more changes will be detected.  Your neurologist can help sort this out.

Question 9

is it true that the more your brain is damaged the larger your visual field defect will be?

Accepted Answer

Depends: If the area of the brain damaged is the occipital lobe or the optic radiations, then visual field defects can occur.  Generally damage at its maximum occurs immediately and over time there can be a lessening if the areas recover.  Of course, the larger the initial damage, the more changes will be detected.  Your neurologist can help sort this out.

Question 10

is it true that the bigger the visual field defect, the worse the brain is actually damaged?

Accepted Answer

Yes and no: A visual field defect doesn't have to occur from brain damage. For instance a detachment of the back of the eye(retina) can cause a visual field defect. However, if the cortex of the back part of the brain is damager(occipital lobe of brain) thden the more damage, the worse the eye symptoms.
