Eye floaters from serious eye trauma like a fist in the eye?

Eye floaters from serious eye trauma like a fist in the eye?

Can happen: 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

Could gazing at home led light or ice cold compress on eyes afterwards lead to retina or cornea damage causing blurred vision of bright objects?

Could gazing at home led light or ice cold compress on eyes afterwards lead to retina or cornea damage causing blurred vision of bright objects?

Not usually.: But, of course, it depends on how bright the light and how long you stare. Cool compresses are even less likely to cause these problems. If you are having changes in your vision, please see a board certified ophthalmologist in your area for a quick examination. Eye sight is a precious thing, and should be protected. ...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?

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

Can watching small screens (phones, portable consoles, games) cause eye damage or blindness?

Does everyday eye accommodation, focusing or blinking worsen pigmentary dispersion syndrome?

Does everyday eye accommodation, focusing or blinking worsen pigmentary dispersion syndrome?

A little bit: The motion of the iris against the underlying fibers that support the lens (zonules) rubs off the pigment from the back of the iris which is the basis for pigmentary dispersion. A little bit comes off with everyday normal use and it can be accelerated with athletic pursuits. As long as your ophthalmologist feels that the internal eye pressure is not being increased, this is ok. ...Read more

Micropsia: Yes, it can if the macular pucker is severe enough. Micropsia is a condition in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema,macular degeneration, and more ...Read more

Small circle/ring, dark shadow/"cig light coil" shaped; appears bottom or left of eye when blink fast/after light glare. Appears same spot/disappears?

Flashes ; floaters: The clear gel that fills eyeball is normally attached to all parts of 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 ; floaters. This can indicate a retinal tear. As the retina detaches, change or loss in your side vision is the next symptom. You should see your eye doctor to check the retina. ...Read more

White part around pupil turning blue/gray?

White part around pupil turning blue/gray?

Scleral ectasia: This could be arcus senilus as mentioned by dr. Fishburn, but a blue/gray color on the white part of the eye may be a scleral ectasia. This is a thinning of the sclera (white part of the eye), allowing the layer below it (the choroid) to show through. This is a normal aging change in some people. Also, a surface pigmentation (conjunctival nevus), could also give such a look. See an eye care pro. ...Read more

Question about refractive errors; can you change the eyeball shape like braces move teeth?

???: What an unusual question. Not a stupid question at all, but one that i think both ophthalmologists and orthodontists alike will be stumped by. Surgical reshaping of the eye is done to correct visual pathology and orthodontics corrects dental arch pathology, other than that, I am unable to help you with an intelligible answer! ...Read more

Red eye lines , red spots on the corner of eye .. Play my phone a lot .. Eye degree 500+ . Wearing specs .. No eye drops nothing else help please !

Depends how long?: If you've just noticed it now, and it's not hurting, and just red spot, make sure your doctor watches it. If it's spreading, painful, and you keep touching it, or related to possible dust orbacteria from phone use, or a recent viral cold, and no discharge, try using lubricating saline drops (without perservative).Then, have your eye doctor examine you fully. It could be just irritated capillaries. ...Read more

Acrysof toric lens put in R eye 10/14. +5 -2.75 correction. Good vision, etc. Temporal crescent. Flicker in most light. None in dark. Prognosis?

Post op cataract: It appears from your question that the surgery was done October 14th (today is 10/17). There are a number of visual symptoms that appear in the first few days / weeks after cataract surgery that resolve spontaneously. The temporal crescent and flickering are very common and almost always resolve. One theory is that the implant becomes more secured within the capsular bag during this period of time ...Read more
