There is a linear echogenic membrane in the posterior compartment of the left eye that is partially mobile and crosses the intersection of the optic nerve. Some floating echoes in the vitreous chamber would be in keeping with resolving hemorrhage in this setting.
Case Discussion
Posterior vitreous detachment (or hyaloid detachment) occurs when the retinal layer and vitreous body/posterior hyaloid membrane dissociate, with an intervening fluid collection forming in the sub hyaloid space.
