Constricted Visual Fields (Overview)

A constricted visual field occurs when you no longer can see objects to the side of your central visual fixation. In this condition you tend to collide with objects that are hidden from you because they are located within and hidden by your peripheral blind area.

What are constricted visual fields?

What are constricted visual fields?

Tunnel vision.: Many causes for tunnel vision. Retinal dystrophies such as retinitis pigmentosa, degenerative conditions such as advanced stage glaucoma, vascular conditions such as occipital stroke, and post traumatic conditions such as traumatic optic neuropathy all can constrict visual fields. Malignant or benign brain tumors are rare causes of tunnel vision. ...Read more

Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?

Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?

Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity. PROVE Study. http://www.aaojournal.org/article/S0161-6420(14)00344-3/references AND https://clinicaltrials.gov/ct2/show/NCT01162356 ...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

What produces blindness in the peripheral visual field of each eye's temporal hemiretinal half?

What produces blindness in the peripheral visual field of each eye's temporal hemiretinal half?

Hemi-field loss: Is usually due to a pathology posterior (behind) to the eye itself. A lesion or area of pathology will usually be located from the area of the pituitary gland (approx. just forward of central brain) where the optic nerves cross to anywhere along the optic radiation ending at the occipital lobe (portion of the brain at the lower back of the skull). An MRI or CT can usually identify the cause. ...Read more

Is double vision affected by brightness of ambient light?

Is double vision affected by brightness of ambient light?

Yes it can: If the double vision is seen with either eye closed, then it may be caused by a cataract whicfh is affected by ambient lighting. If the double vision is elimitated with covering either eye then this is true diplopia. In some patients, when the eye turns outward ambient light can cause glare. ...Read more

How is visual acuity preserved in bitemporal hemianopia?

How is visual acuity preserved in bitemporal hemianopia?

Nerve fiber pattern: Bitemporal hemianopia is the classic later stage vision pattern in advancing pituitary tumor. Generally the central fibers, which carry the best acuity are affected later in the condition. A great deal of vision loss would have to be ignored by someone with this condition before the nerve fibers for the central acuity start to drop out. ...Read more

Visual field test normal w/minimal peripheral vision loss. After diagnosed w/glaucoma feel more nervous driving such as changing lanes. Psychological?

Visual field test normal w/minimal peripheral vision loss. After diagnosed w/glaucoma feel more nervous driving such as changing lanes. Psychological?

MAYBE: Ask ophthalmologist to check visual accuity. If there has been no change, youre getting unnecessarily anxious. Remember the possibility of trouble doesn't mean it's there now. ...Read more

Can a large eye floater affect peripheral vision in a visual field test.

Can a large eye floater affect  peripheral vision in a visual field test.

Yes: Visual field testing will occasionally pickup small areas of visual field depressions if the floater is particularly large and thick, as some patients may have. Since they move, a repeat visual field should also show the depression to have moved. I would not however expect a large visual field abnormality from a floater and certainly l recommend an exam to rule out any problems by an eye md. ...Read more

Can astigmatism cause visual snow?

Can astigmatism cause visual snow?

No: Visual snow are "floaters". They are inside the eyeball. Astigmatism is a problem with the curvature of the cornea. Doesn't have to do with the inside at all. Same organ but different physiological derangement. ...Read more

Are visual field defects always present in glaucoma patients?

Are visual field defects always present in glaucoma patients?

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. ...Read more

Does glare and rainbow halos is that caused by visual migraine?

Does glare and rainbow halos is that caused by visual migraine?

Visual migraine: Are usually associated with visual disturbances that start in your central vision and expand outward. Glare and halos are not usually related to this visual phenomenon and indicative of other visual pathway abnormalities. Something as simple as dry eyes, to refractive error (glasses) to cataracts can cause the symptoms you are describing. A comprehensive eye exam will give you the solution. ...Read more
