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.
