Is this real?

Hi

Does this look familiar to anyone?
Please bear with me. This is not a troll post.

Does it look remotely familiar to any know parasites / organisms?

Thank you

I have gone to an ophthalmologist and they said they cannot see anything.
Try another.

I take it you skipped over the reading the forum rules part?

Rules:
1. No bad language of any kind.
2. No personal attacks of any kind. This includes ridicule, condescending remarks or threats.
3. No criticism of products that you are not satisfied with. This is for legal protection.
4. No plagiarism of any kind. This includes the upload of images that you do not own, recopying of text.
5. No posts that are not microscopy-related. Posts that have a connection to microscopy but can not be categorized elsewhere can be posted into the "Off-topic" section.
6. No posts with the only intent of advertising. Sometimes links are to products are useful for microscopy. In this case I will make a decision.
7. No abuse of the personal messaging system (no spam, no attacks, no nothing)
8. No false information or pseudoscience. Stuff relating to live blood darkfield microscopy will be removed, as it is medically misleading and therefore dangerous.
9. No medical advice should be given and posters should not ask for medical advice.

I am not asking for medical advise. I am asking if it looks like anything anyone here is capable of identifying.
Or if it looks remotely like any known organisms.

Not exactly familiar in appearance ... but my own experience was comparable:

I reported to the eye-clinic at the hospital because I thought I had 'something in my eye' ... the visual impression being of perhaps a fragment of insect wing or plastic film.

No-one could find anything !

A couple of visits later; I was seen by the senior Consultant, who was obviously very experienced in examination with the slit lamp. ... His comment was basically "the reason you think you have something in your eye is that you have something in your eye ... but it's not on the front surface of the cornea, it's behind it"
It transpired that I was suffering "iris pigment shedding" and my highly visible floaters were in the aqueous humor.

Note: Hopefully in line with the forum rules ... This is not intended as medical diagnosis or advice, it is merely a recommendation that you seek the right person, using the right kit, to do a thorough examination.

Yes sorry i had to get rid of medical references due to some rule as someone confused my question with asking for medical advise. Which was not the case.

Any case. I suspect L. loa microfilariae or Mansonella perstans.
At least it is closely resembling of this thing in my vision.

It all started while doing backpacking in a remote wilderness area. From there my eye has not been well, and i see this thing dead center in my vision.
Like i drew.

And if i search for pictures resembling it i only come with the parasites listed above.

In lieu of giving medical advice, I have never seen anything like this.. I have the standard floaters and imaginary flying insects on the edge of my vision. but I have nothing this drastic... Sorry I can't help...

Hi, does the floaters and imaginary flying insects are more visible when choosing a higher magnification? At least for me works this way. After 400x I see all sort of things flying around :shock:

That would depend on the condition of your microscope and your microscopy skills. Increasing the magnification usually darkens the image. Normally, the adjustment of the instrument compensates for this mostly, keeping the illumination level of the observed field, fairly constant. If that is not done, dirt and any imperfections in the optical system will be more apparent and as well floaters in the eye are more apparent.
Floaters are still there when the illumination level is higher, it is just that due to most of them being quite transparent, they are harder to see. Raising the magnification and darkening the field allows some to be seen , that previously could not be.

Floaters should be easy to distinguish from other FOV phenomenon. If you jerk your eye's point-of-focus to the side, the typical floater should lag a bit, i.e., not move as much as the jerk, but after a second or so, "catch up", and slide back to near the center of the field (at least the especially annoying ones end up back there!)

As an aside, it would seem that the sharper the floater, the closer it must be floating to the retina. Although as in a microscope, the amount of opening of the iris might change this effect.

@apochronaut @billbillt @wporter, many thanks for the explanations!
