Doc ruled out retinal tear, said full pvd yet to start but there's vitreous detachment(my floaters), what is diff betwn full pvd n vitreous detachment?

Synonymous: A "full" PVD and a vitreous detachment are the same thing, albeit a "full" one probably was meant to tell you that the posterior vitreous has completely detached from the posterior part of your eye. The vitreos humor, as we age, begins to separate from the posterior of the eye, generally without compromise to the retina or blood vessels. This takes awhile to complete itself (weeks to months).

See below: A partial vitreous detachment occurs before a full PVD does. Once the vitreous separates from the optic nerve and macula, it is considered a pvd.

Same thing: A PVD is a posterior vitreous detachment. Vitreous detachment can be partial or complete, but it is nearly impossible to tell on examination. Thus, as long as there are symptoms of flashes, it is usually assumed that the vitreous detachment is still progressing. Floaters occur and persist with or without progression.
