Con- vection represents slow spontaneous motion of particle currents within a cavity (i.e. in endophthalmitis); after- movements are defined as continued tissue motion after cessation of eye movement (i.e. after vitreous detach- ment) [9].
(a) Retinal detachment; note how it is tethered to the optic disk (white arrow); (b) vitreous detachment (white arrow) crossing midline over the optic nerve, which helps differentiate it from a retinal detachment; (c) endophthalmitis; (d) color Doppler over the central retinal artery and vein and flow in the ciliary artery (white arrow showing blood flow as red Doppler shift through the retina).
In the case of endophthalmitis, US may be the only means of obtaining a view of the anatomy of the posterior chamber because of hypopyon or dense media opacities [10].
correlation between the specific causative microorganism and the US findings and found that streptococcal species were more likely to be associated with intense, severe vitreous opacities, whereas the Gram-negative species and culture-negative endophthalmitis were associated with minimal vitreous opacities.
Evidence for endophthalmitis can also be found by measuring the velocity of blood flow in the OA.
