Assistive Devices Vision Impairment And Blindness
Vision impairment and blindness are conditions in which a person cannot see well or see at all, even with glasses or contact lenses. If a person's best vision (with correction) out of either eye is only 20/70 - 20/200, he is impaired. If he can see no better than 20/200 or his visual field is no more than 20 degrees (severe "tunnel" vision), ...Read more
May be: Only time will tell about the improvement it all depends what is the extent of permanent damage. ...Read more
Visual field test normal w/minimal peripheral vision loss. After diagnosed w/glaucoma feel more nervous driving such as changing lanes. Psychological?
Depends: On the amount of peripheral vision loss. A visual field is performed to detect the amount of binocular horizontal visual field. For example, some rules require it to be at least 20 degrees to drive. Driving safely with reduced peripheral vision means turning your head always in the direction you want to look. ...Read moreSee 1 more doctor answer
Maybe so: Computer programmers have needs that are different from other computer users. Age and need for glasses also play important roles. The stronger the prescription need, the more peripheral distortion exists. There are several glasses that come either with "blinders" or wrap-around lenses. Your optometrist or optician can likely build or modify a pair of glasses to accomplish your goal. ...Read moreSee 1 more doctor answer
Usually not: If the vision in one eye is normal, the lowered vision in the fellow eye will not impede academic achievement. There is little in academics that requires excellent vision in both eyes. The only areas affected would be those requiring stereoscopic vision. I have know doctors, lawyers, engineers and professors who have a lazy (amblyopic) eye. ...Read more
Macular pucker.with distortion. Close-up vision great, distance vision not as good. Could macular pucker impair distance vision only and not close up?
Not likely : Macular pucker affects the retina which detects images at any distance. The lens and cornea focus images at various distances onto the retina. So a problem at only one distance usually is a problem other than the retina. However, some people may only notice distortion from a macular pucker at a particular distance. A review of your records/images would help clarify. ...Read more
Will hearing aid use prevent further damage and hearing loss for someone with sensory neuronal hearing loss?
Perhaps.: I would maintain that the answer is "maybe". There is at least the suggestion that if you restore stimulus to the auditory cortex via the current hearing aid technology, that part of the brain that has been deprived of input can actually improve it's function. The brain has "plasticity" and might well slow or even arrest additional hearing loss if incoming signals are restored. ...Read moreSee 2 more doctor answers
Maybe: One of the long term problems with rk surgery is the lack of long term stability in some patients. Sometimes, their prescription keeps changing over time, usually making them become more far-sighted. There are some therapies available that may help. Consult a corneal specialist. ...Read more
In unilateral glaucoma with advanced visual field loss in that eye but perfect vision in unaffected eye is it safe to drive relying on good eye?
Generally yes: With 1 normally functioning eye & 1 that has severe visual field loss, your function is largely dependent on your ability to adapt to the missing field areas. As an American driver, visual field loss in the left hemifield & diffuse visually field loss in the right eye was associated with more driving impairment. Interestingly, a large % of monocular patients did well driving. Driving skills vary. ...Read more
Will "close work" (e.g., computer at work, reading, etc) be impactful to peripheral lattice retinal degeneration? Or only for myopia progression?
Not likely: There are some animal studies that suggest that intense near work in children could enhance myopia. I don't believe that mechanism is still at play by age 41. There should be no impact on lattice degeneration from computer work or reading. Lattice degeneration per se does not progress. What changes in the eye is the state of the vitreous gel and its relationship to the lattice. ...Read more
Early stage glaucoma & moderate stage epiretinal membrane same eye not affecting vision much now. W/both diseases potential for central vision loss & peripheral vision loss causes anxiety. Prognosis?
The risk is very low: An epiretinal membrane is a common finding in 60 y/o female and typically remain visually insignificant. If it becomes visually significant, surgical treatment is very successful. Mild glaucoma is very treatable, and with appropriate followup and treatment, peripheral vision loss can be prevented. Central loss is extremely rare. ...Read moreSee 1 more doctor answer
Recently diagnosed with glaucoma. No peripheral vision loss. 30% optic nerve damage. With treatment will nerve damage cause loss of vision?
Probably not: Glaucoma is readily treated with anti-pressure medication which should prevent any further damage in almost all cases. This is handled by ophthalmologists (you are not seeing an optometrist i hope?) who deal with this daily. There is a step ladder of treatments -- medication, laser, surgery to prevent further damage which can be quite effective. ...Read moreSee 2 more doctor answers
Loss of vision reflects the inability to perceive images. Such a phenotype can be due to occlusive or barriers to light (e.g. cataracts) through retinal alterations (e.g. wet macular degeneration) to optic nerve lesions (e.g. from a pituitary adenoma) to central nervous system ...Read more
