vitreous base

vitreous base 

A dense, broad band (2 mm wide) of vitreous attachment to the peripheral retina near the ora serrata. Collagen vitreous fibrils blend anteriorly with the basal lamina of the non-pigmented epithelium of the pars plana of the ciliary body and posteriorly with the internal limiting membrane of the retina.

Retinal re-detachment usually occurs as a result of reopening of old breaks, formation of new breaks during oil removal, inadequate laser, multiple previous retinal surgeries, incomplete vitreous base shaving and proliferative vitreoretinopathy23,24.
However, this surgery has challenging features, which include poor pupillary dilatation caused by the postoperative inflammation, more mobility of the posterior capsule due to the absence of the vitreous, loose zonules and pre-existing posterior capsular dehiscence associated with lengthy vitreoretinal surgery, multiple procedures, and vitrectomy involving vitreous base dissection.5,12 Thus, the surgery for post-vitrectomy cataract may have more difficulties and higher probability of complications.13 In this study, we improved the traditional surgery by performing phacoemulsification outside the capsule to treat the cataract after vitrectomy and achieved good surgical results.
In the PPV, cut and flow rates were adjusted according to the patient's condition during core vitrectomy and removal of the vitreous base and hyaloid.
This procedure is a modification of the traditional 25-gauge PPV, consisting of a mini-invasive vitrectomy with a limited vitreous removal surrounding the retinal break(s), without core vitrectomy or shaving the vitreous base over 360[degrees].
A PVD that extended as far as possible to the vitreous base was created, followed by vitreous shaving with scleral indentation.
It may also help the surgeon to trim the vitreous base and facilitate management of pathologies in this area.
Retinal tufts are internal projections of retinal tissue located at the area of the vitreous base. They are classified as noncystic, cystic, or zonular traction.
Similar white material was present anterior to the vitreous base and extended circumferentially for 360[degrees] (Figure 3, A).
Fundoscopic examination revealed subretinal hemorrhage, predominantly at the macular and posterior pole, and a large pool of blood between the retina and the vitreous base (Lancet 2005;365:330).
Some surgeons have used 7 mm optic intraocular lens to avoid the edge effect of IOL during peripheral vitrectomy like vitreous base shave.
In all patients meticulous removal of the vitreous was performed at vitreous base and around the impact site, and posterior vitreous detachment (PVD) was induced.
ERMs are often accompanied by retinal folds and are distinguished from the posterior vitreous base by the formation of a thicker reflective band.
