Visual Field Defects (Overview)

Certain conditions, i.e. glaucoma, cause loss of retinal sensitivity to portions of the peripheral vision. Macular disease affects central focusing vision. Visual field defects are usually monitored with an automated machine that measures a person's ability to see tiny spots of light in the peripheral and central vision. What we measure when a person reads a vision chart is central vision.

Can medical conditions in the brain, excluding strokes or tumors, cause a visual field defect?

Can medical conditions in the brain, excluding strokes or tumors, cause a visual field defect?

Yes: Other causes include multiple sclerosis, infection (e.g., abscess), and tumors in the pituitary gland that press on the brain. Visual field defects can also be seen with diseases of the retina or optic nerves. Also late in the course of some neurodegenerative disorders such as alzheimer's disease higher centers for vision can be affected and visual deficits can be seen. ...Read more

Can anyone tell me more about having visual field defects?

Can anyone tell me more about having visual field defects?

Visual Field Loss: Hooding of the upper lid (mostly upper outer areas) are caused by elasticity loss and drooping. Forehead sagging and the lid elasticity loss are common causes. Visual field analysis is done in eye doctor offices, using an enclosure with many small lights and patient acknowledges seeking them light up in a closed background. This determines % of vf loss. ...Read more

Are visual field defects always present in patients with glaucoma?

No: Sometimes the elevated pressure will "eat away" at the myelin in the optic nerve causing an increase in the cup disc ratio before field damage occurs. This can give the patient a false sense of security and lead to noncompliance and subsequent damage. ...Read more

Are visual field defects always justification for bleph?

No: Many insurance companies are not covering for only loss of visual field. (medicare requires loss of levator muscle (true ptosis) or not pay. There are many degrees of vf loss, some will cover upper lid surgery when vf loss is >30% measured by vf analysis. Insurance co are following medicare lead and are denying except for muscle functional loss. ...Read more

Ideas? What nonprocessive conditions cause a visual field defect?

Ideas? What nonprocessive conditions cause a visual field defect?

CNS problems: Many strokes will cause a visual field defect which is stable and non-progressive although the initial loss can be devastating. Trauma to the optic nerve or the visual pathways can also do this. Most other lesions that register as a field defect are commonly progressive unless treatment is given. ...Read more

Are visual field defects present in glaucoma?

Are visual field defects present in glaucoma?

Yes: By definition, glaucoma is a group of diseases which causes characteristic optic nerve damage with corresponding visual field defects. These defects are not always symptomatic to the patient and may only be detectable through special testing. ...Read more

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

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

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. ...Read more
