Vision (Definition)

Vision is a feature of a person's brain that allows him to see. He must have normal eyes, optic nerves (that stretch from the eyes to the back of his brain), and visual cortex (the vision center in the brain), in order to see properly. An ophthalmologist is a ...Read more

Two little black dots in my field of vision that float?

Two little black dots in my field of vision that float?

Floaters: It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery. ...Read more

At times i see black sgiggle lines in my vision field?

At times i see black sgiggle lines in my vision  field?

Likely Floaters: It's possible you are seeing floaters in your visual field, particularly if they're seen in daylight while looking at a bland backdrop, like a sky or white wall. The floaters should not block or affect visual acuity.Or if your linear squiggly lines have a building, perhaps curvilinear pattern that shimmers or has a sawtooth or klaidescopic appearance disturbing vision with/without pain: ?Migraine. ...Read more

Why do I see colors in the field of vision every time i look into a bright light?

Why do I see colors in the field of vision every time i look into a bright light?

Visual phenomenon : Bright light bleaches the cells in the retina which relay information to the brain. When bleached, the nerve signals they emit are not accurate of the outside world. They cause the brain to interpret persistent colored lights, this fades as the cells recover. ...Read more

Im seeing a black line (like a strand of hair) in left side of peripheral vision 24/7 . Went to hospital and they said it's cataract. Is that true?

Im seeing a black line (like a strand of hair) in left side of peripheral  vision 24/7 . Went to hospital and they said it's cataract. Is that true?

Unlikely: This is almost certainly a change in the pattern of the vitreous gel in the back of your eye. This is an aging process called vitreous syneresis. Cataracts alter the vision by lowering the acuity and causing light glare, but they do not insert "lines" in the vision. If this worries you, see your ophthalmologist for confirmation. ...Read more

I am seeing a small type like sheet billowing in the bottom of my eye - thought floaters were dark in color.?

Appointment : You need a dilated eye exam by an eye md to examine the retina. It's possible you have a retinal detachment , but other possibilities include a posterior vitreous detachment. The latter is more common and less of a visual problem. The former has to be treated. Floaters can vary from small discrete spots to veil- like. Retinal detachment often results in flashes and a rather gray or dark shadow ...Read more

Why do I see flash of yellowish lights in the corner of one eye after I turn out the lights?

Why do I see flash of yellowish lights in the corner of one eye after I turn out the lights?

Retinal Irritation: Light flashes indicate that the tissue that you see with, called the retina, is being irritated. The most common cause is rapid cessation of eye movement, which can cause your eye muscles to stretch the wall of your eye. Or, sudden normal movement of the gel inside your eye, usually after the age of 60, can stretch the retina. Dark spots in your vision mean that you need to see an eye doctor. ...Read more

Scary eye situation. Had trouble seeing in center of eye then zigzag prism in arc-like line. What was that?

Scary eye situation. Had trouble seeing in center of eye then zigzag prism in arc-like line. What was that?

Migraine aura?: It's not clear from your description and it would be helpful to know how long these symptoms lasted, but the "zig-zag prism in arc-like line" comment makes me think of a migraine aura. These often make the vision temporarily hazy, then form a building arc of lights in a zig-zag just off center, which lasts 5-20 minutes, then resolves. Some have a headache after, but many just get the aura. ...Read more

Saw rotating "barber's pole" black & white pattern out of corner of left eye for 2 secs. Another ocular migraine? Looked to that side, it was gone.

Saw rotating "barber's pole" black & white pattern out of  corner of left eye for 2 secs. Another ocular migraine? Looked to that side, it was gone.

Maybe: Your typical visual hallucinations from acephalic migrains usually last 10 to 15 minutes. However, not everyone has textbook symptoms. Vitreous pulling on the retina could cause visual symptoms as well, which uncommonly can lead to retinal detachment. I would get a full dilated eye exam. ...Read more

I just had a sudden burst of floaters in my right eye then i saw bright white dots floating around the central vision, is this a one off or serious?

I just had a sudden burst of floaters in my right eye then i saw bright white dots floating around the central vision,  is this a one off or serious?

Could be serious.: Consider it to be serious until you have an eye exam to insure that there is no sign of a retinal detachment. It could be due to separation of the vitreous from the retina. While this is happening, it is good to be very cautious and limit activity and straining. Sometimes detachments and tears occur after the initial symptoms so it is best to be followed by an eye specialist. ...Read more

11 weeks after retinal reattachment (gas bubble +new lens) whai's the whirling transparent 'fan' I sometimes see in lhe centre of my field of vision?

11 weeks after retinal reattachment (gas bubble +new lens) whai's the whirling transparent 'fan' I sometimes  see in lhe centre of my field of vision?

May be normal postop: You might want to consult your retinal surgeon on this, but I have had patients with very similar symptoms after retinal detachment surgery, and sometimes after retinal laser surgery. It is probably a false image created by an area of the treated retina. Usually it resolves on its own with time. Again, every case is different, so ask the retinal specialist if you need to be examined. ...Read more

Most often yes: Sometimes no, if it does not, please look into a corneal tattoo (rarely needed but works very well to block the extra light coming through or colored contact lens. ...Read more

When i go from a well-lit room to a dark/dim room sometimes i see a small, bright, black speck in my vision. Sometimes twice in a row, but not always?

When i go from a well-lit room to a dark/dim room sometimes i see a small, bright, black speck in my vision. Sometimes twice in a row, but not always?

This depends: If this is a new phenomenon for you, it could represent vitreoretinal traction (i.e. An impending posterior vitreous detachement) and you should have a dilated retinal examination by an eye care professional asap. It may also be mooren's light flashes, a benign phenomenon probably induced by the dilating iris tugging on the retina generate when going from light to dark.. ...Read more
