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.

Can you tell me about the visual field test?

Benign and painless: In this test you will sit looking at a dome on which lids are arrayed or a light is projected Your identification is by a signal button and the mapping of what you saw is produced as a clue to changes in glaucoma, or to the nervous system.

Pain to move left eye, blurry vision lower 1/2 visual field that eye only (is like a greasy film over bottom 1/2 of eye). Blood pressure perfect?

Optic neuritis: You need to see an ophthalmologist asap. The biggest concern in a woman your age would be optic neuritis. This would explain your symptoms best. You need a thorough exam by an ophthalmologist first the ophthalmologist may order an MRI or have you see a neurologist depending on the findings.

In monitoring open angle glaucoma, if oct test results taken 1 yr. Apart are different, can it mean glaucoma isn't stable? No change in visual field.

In monitoring open angle glaucoma, if oct test results taken 1 yr. Apart are different, can it mean glaucoma isn't stable? No change in visual field.

Open angle glaucoma: By definition will diminish your retinal nerve fiber layer (rnfl) over time if not well controlled. Serial rnfl scans are highly sensitive and can detect small changes prior to a formal visual field test demonstrates changes. Questions if loss is occurring can be answered by looking at serial scans of the rnfl over time and looking for trends. So, yes, it may not be stable and requires follow up.

Have glaucoma w/thinning optic nerve. Dr says visual field normal & shading at very top of field could be eyelash or eyelid causing it. Possible?

Could be: It is very important to have a regular eye exam by your ophthalmologist. If your doc told you that is was normal then its. Some time if the person has a droopy excessive eyelid (dermatochalsis) it may cause an upper visual field defect.

I was wondering are black dots appearing in the visual field normal?

Not in my experience: You should see your doctor to evaluate. "mobile" black dots could be vitreous floaters, "stationary" dots are possible retinal or neuro issue. You do need an exam to evaluate.

I have visual trails (bursts of light that cross my visual field). Never happened before, please help?

Vitreous or migraine: The clear gel that fills eyeball is normally attached to the inside of the eye. As we get older it can become more liquid (watery) and detaches from the back of the retina causing flashes as it pulls on the retina. This is made worse when reading, looking side to side, basically with eye movement. Scintillations (flashes) occur with atypical migraine- with or without headache.

What causes dark spots in your visual field?

What causes dark spots in your visual field?

Floaters: It depends on what condition you have. Most of the time this occurs as you age. The vitrous in your eye shrinks and can sometimes detach from the retina. If the back part of the vitrous falls into your line of sight you may see spots or even spider webs

How can the visual field change with glaucoma?

There are typical…: Patterns of glaucomatous visual field loss. The goal of treatment is to try to keep the visual field from getting worse. Typically the defects start out in the periphery, either nasal (near the nose) or temporal (near the temple). Arcing type patterns are common. Sometimes the central vision is affected in the early stages, however it is typical for the central vision to change as a late finding.

What are these colorful spots in the visual field?

Entoptic: Entoptic events are the result of internal factors causing the sensation that there is an object or image. Examples are phosphenes or flashes that occur when the vitreous is pulled on. Colorful dots are sometimes seen in the visual field against a hazy background. These can occur because stimuli other than photons can trigger the photoreceptor cells or other cells en route to the optic nerve.

Are visual field defects always justification for bleph?

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.

What is the definition or description of: Visual field defects?

Visual field loss: 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.
