“…1 After PVD, avulsion of retina vessels, vitreoretinal traction, and retinal flap tears may develop at areas of strong vitreoretinal adhesion. Conversely, fragments of hyaloid membrane may be left undetached on the posterior retina without causing significant retinal changes.…”

Aims To study the pattern of residual undetached cortical vitreous (RCV) after posterior vitreous detachment (PVD) in eyes with rhegmatogenous retinal detachment (RRD) and to examine the relationship between RCV and the development of epiretinal membrane (ERM). Methods A prospective study was conducted in 33 consecutive patients with clinically evident PVD who underwent pars plana vitrectomy for RRD. During vitrectomy, triamcinolone acetonide (0.2 cm 3 , 10 mg/cm 3 ) was applied to stain the RCV. The pattern of the staining were recorded. The formation of postoperative ERM was correlated with the staining pattern of RCV. Each case was followed for at least 6 months.Results In all, 23 of the 33 patients had RCV of variable size, with a single stain patch observed in 13 patients and multiple patches in seven patients. Large circumferential areas of staining at the mid-periphery were noted in three patients. A total of 10 cases had staining over the fovea and five patients had staining over the disc. ERM developed in seven patients during follow-up. None corresponded to RCV.Conclusion RCV is common in eyes with PVD and RRD. The macula and disc area are the most frequent locations for these vitreous islands. The relationship between RCV and ERM remains to be investigated.

“…25,35,50,54 Via the vitreo-glial-axonal attachments that exist, vitreous detachment can also rupture glial cells. 36,37,39,41,55 Electrolyte imbalances may initiate a wave of depolarization via ephaptic transmission, with spreading depression a cause of amaurosis fugax.…”

“…21,22,24,67,69e71 Spontaneous posterior vitreous detachments, on the other hand, are most likely to course through the top of the disc and from its temporal aspect, and progress downward. 26,41,50,65,68 They may occur over minutes to hours often during rotational eye movements 25,26,41 while awake or during rapid eye movements while asleep. Such vitreous dissection may momentarily be arrested where epipapillary membrane attachments are strongest, at the nasoinferior aspect of the disc, the site of fetal fissure closure where central disc vessels often bifurcate and Cloquet's canal may sometimes encompass a Bergmeister's papilla.…”
