What is the best treatment for a distortion in some part of visual field?

Visual field problem: "distortion" in the visual field is an unusual description. Usually distortion is described in the central or near central vision where straight lines appear crooked or bent. This virtually always indicates a retinal condition and should be evaluated asap. In the peripheral vision, problems are usually described as a vision loss or blind spot. This too should be checked. Possibly visual migraine. ...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

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

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. ...Read more

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 ...Read more

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. ...Read more

Is visual field and peripheral field the same thing?

Is visual field and peripheral field the same thing?

almost: Visual field refers to the patterning of the reception of the entire retina. As a subset, the peripheral field refers to the outer portion of the full visual field. So they refer to something the same but visual field is more comprehensive. ...Read more

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. ...Read more

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. ...Read more

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. ...Read more

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

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. ...Read more

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

Visual field test 2 mos. Apart w/fixation loss of 6/12 in 1st test & 3/14 in 2nd test. 1st test showed more damage than 2nd. Which test is most right?

The second : Less fixation losses on the second test means you were focusing on the fixation target more times than on the first test. Therefore, the second is the most accurate test. ...Read more
