What causes your depth perception to be off after a vitrectomy for a detached retina?

What causes your depth perception to be off after a vitrectomy for a detached retina?

Re-calibration: A vitrectomy removes some of the vitreous humor from the eye. Light goes thru this and is refracted in a particular manner. After vitrectomy, the amount of vitreous is different and your eye, optic nerve and brain have to re-calibrate the incoming light information and the response to it from the brain. Change requires time for adaptation. ...Read more

Can mono-vision cause problems with driving at night or problems with depth perception.?

Can mono-vision cause problems with driving at night or problems with depth perception.?

Yes: Mono vision depending on the disparity in vision between the two eyes can be a definite cause ifa drop in depth perception. You can test this put by comparing with contacts vs glasses by taking the stereo fly test. You might be under corrected and this is causing night myopia. ...Read more

How can you know if you have depth perception?

Evaluate: Your ophthalmologist has tests for this. You can estimate your ability by seeing movies in depth like Avatar, or getting one of many books at the bookstore e.g. "Magic Eye" which require perception in depth to see in depth. ...Read more

What does it mean when your depth perception is poor?

What does it mean when your depth perception is poor?

Stereo vision issues: Stereovision is the ability to see in depth using the two eyes together. If one eye sees poorly or the eyes do not work well together, your depth vision is likely to be impaired. If this is your problem, you will notice this especially if you look at a stereovision movie like avatar when the experience will not be so well for you. ...Read more

Can you tell me about depth perception problems in children?

Can you tell me about depth perception problems in children?

Depth = 3D vision: Depth perception, or 3-d vision, can easily be tested by an ophthalmologist in the office. Any problems in depth perception arise from either one of the two eyes not seeing well, or the eyes are not aligned properly. An ophthalmologist can tell you which of the following can cause this problem in your child and how to treat it. ...Read more

What to do if I failed depth perception test but have 20/20 vison?

What to do if I failed depth perception test but have 20/20 vison?

Probably little: Congratulations on the 20/20 vision - is this in both eyes separately? If only in one eye, that could be the reason for the lowered depth perception. Some are born without the part of the brain wiring that makes depth perception. Generally loss of depth perception is not fixable but generally also is not a problem for most life activities. ...Read more

What does it mean if I have failed depth perception test but have 20/20 vision?

What does it mean if I have failed depth perception test but have 20/20 vision?

Separate functions: 20/20 refers to the acuity of vision, hopefully at this level in both of your eyes. Depth perception (stereovision) refers to a brain function in which the input from both eyes together is summed producing an image in depth. Some lack this part of the brain wiring but can see well otherwise. This may be true for you. ...Read more

Hi doctors, was just wondering what is depth perception related to--where does it come from?

Binocular: True depth perception (stereopsis) is a function of the visible portion of the brain requiring input from both eyes. The ability to fuse the two eyes is inborn and a very strong reflex. It is a wonderful, almost magical function of a portion of the vision. There are many books with interesting pictures which requires true depth perception for them to work. ...Read more

Could 3d glasses enhance your depth perception?

Could 3d glasses enhance your depth perception?

No: 3d glasses do not increase depth perception. They allow one to experience 3d vision from a flat screen when the image has been formatted for this. People who have poor 3d vision cannot see in 3d in any situation. 3d vision develops in early childhood and cannot be changed after this time. ...Read more

What can you tell me about monocular and binocular cues for depth perception?

What can you tell me about monocular and binocular cues for depth perception?

Separate functions: Binocular clues involve the use of stereopsis which is true depth perceptions dependent upon using both eyes together (and is what you use when you see a 3-D movie). Monocular clues depend upon the catalog of image types and sizes so you know how far things are by these clues. Those who have lost one eye, depend upon monocular cues for depth understanding. ...Read more

Is it common for peripheral vision and depth perception to start fading at almost the same time?

Is it common for peripheral vision and depth perception to start fading at almost the same time?

No: Neither should fade in normal aging. Near vision does "fade" in a condition called presbyopia. Loss of peripheral vision is sometimes due to serious conditions such as a retinal detachment or glaucoma or retinitis pigmentosa. Depth perception problems can be due to lose of vision in one or both eyes. ...Read more

Is it common for people to start losing their peripheral vision and depth perception at the same time?

Is it common for people to start losing their peripheral vision and depth perception at the same time?

No: Depth perception is a binocular function, meaning that with both eyes functioning you should not have depth perception problems. Peripheral vision can be affected by certain things, most commonly glaucoma, but strokes can affect this. Both are usually not affected. ...Read more

My doctor said I have very little depth perception, what does this mean?

My doctor said I have very little depth perception, what does this mean?

Not too much: There is a center for stereoscopic vision in the brain. If defect you might have poor or no stereoscopic vision which is essential for depth perception. This also can be due to poor vision in one eye. From a practical standpoint, loss of this function is of minimal problem. You need excellent stereo vision to work as a watchmaker, or to be an excellent baseball player. Little else is affected ...Read more

Does coordination problems in a child have anything to do with a lack of depth perception from needing glasses?

Does coordination problems in a child have anything to do with a lack of depth perception from needing glasses?

Perhaps-let me see!!: Poor vision certainly is on the list of things to explore when a kid is "clumsy". It may be things other than depth perception that have to do with vision that can affect coordination, including blind spots, blurriness, unusual eye movements that can affect hand-foot-eye coordination. Any investigation of poor coordination should include at the very least an exam of the eyes and visual screening. ...Read more

I wear monovision contacts and lose some depth perception when driving. Is it possible to wear glasses over the contacts to improve this when driving?

I wear monovision contacts and lose some depth perception when driving. Is it possible to wear glasses over the contacts to improve this when driving?

Yes: Glasses can be made with window glass over the distance eye and a correction for the near eye which renders it clear at distance. This is commonly done and helpful when driving at night or in the rain. ...Read more

What happens to your depth perception after an injury in one eye?

What happens to your depth perception after an injury in one eye?

Decreases: Depth perception is partially dependent on the ability to fuse an image with both eyes (stereopsis). After an injury that takes the sight from one eye, this will decrease, but you can still use other visual cues for depth perception. ...Read more

What will happen to my depth perception after an eye injury?

What will happen to my depth perception after an eye injury?

It depends: It depends on the severity of vision loss. If vision in the injured eye is poor then depth perception is lost and has to be "re-learned" by visual clues. If vision remains good in the injured eye or can be restored surgically, then depth perception should not be effected. ...Read more
