Question regarding eye floater

[des900]

I notice a thread (shape of a worm) in my vision field of right eye, when i stir eye in bright light (like clear sunny day sky) and this thread moves leftwards when i try to focus on it i also notice few very tiny bubbles around this thread.

An ophthalmologist applied pressure on that eye few months ago & i notice this thread after 1 month after the examination,i don't know if i had this thread before that exam.

Can tonometry or other pressure applying eye tests can cause these threads after months?

Thanks Doctor for clarification

No, no, and no.  We exam the peripheral retina by a technique call scleral depression.  This applies pressure to the peripheral retinal through the sclera and require much more force than squeezing a meibomian gland or tonometer.

Thanks Doctor

After that incident (one ophthalmologist applied pressure on bottom of eyes using his thumb to evaluate meibomian gland secretion) onwards i am scared to see an ophthalmologist as he may again apply one like that.

can tonometry or other pressure applying eye tests have any side effects like floaters,blurriness etc ?

This was not caused by an eye exam.  You need to see an ophthalmologist.  A new onset of floater may indicate a  retinal tear or one that may occur in the next few months.  This could lead to a retinal detachment.
