Some surgeons have used 7 mm optic intraocular lens to avoid the edge effect of IOL during peripheral vitrectomy like vitreous base
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
However, the development of the surgical instruments such as wide-field viewing systems and the increased use of cataract surgery combined with vitrectomy facilitate intraoperative viewing and safe manipulation at the vitreous base
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
17 In the late stage TON patients may suffer from secondary pathological changes that lead to the dysfunction and death of retinal ganglion cells during which the macula lutea and the vitreous base
are dragged by the vitreous body.
ERMs are often accompanied by retinal folds and are distinguished from the posterior vitreous base
by the formation of a thicker reflective band.
One month later, a letter from the HES confirmed that the patient had a partial PVD with a very strongly attached and posteriorly located vitreous base
, giving the appearance of vitreous veils, but that these were areas of strong vitreo-retinal attachment to the vitreous base
and located more posteriorly than normal.
This separation process typically proceeds quickly from posterior to anterior, the vitreous ultimately remaining attached only at the vitreous base
, where the vitreous is inseparable from the underlying retina.
Traction at the vitreous base
is transmitted to the adjacent peripheral retina.
Ten months later the patient went on to develop CMO, probably due to the broken capsule and traction at the vitreous base
