Vitreous Detachment
Abstract
We analyzed the integrity of retinal layers in the area of the CMV scar, integrity of retinal layers at the margins of the CMV scar, margins of the scar and adjacent nonaffected retina, and any structural alterations in the retina or vitreous.
Eleven eyes (50%) had vitreous detached, and 11 eyes att...

Abstract
Two hundred twenty eyes, 175 eyes of the control group and 45 eyes of the retinal breaks group were examined and included in this study. The multiple logistic regression analysis revealed that patients with multiple floaters, and floaters and flashing increased the risk of retinal breaks to 5.8 and...

Abstract
All three patients had clinical findings consistent with SBS, including preretinal and intraretinal hemorrhages. Hand-held spectral domain optical coherence tomography documented focal posterior vitreous separation in four of the five eyes with multilayered retinoschisis in one eye, disruption of th...

Abstract
The preoperative visual acuity was -0.6 +/- 0.176 logMar units. Visual acuity increased postoperatively to -0.3 +/- 0.252 logMar units after 372.6 days. A posterior vitreous detachment was found in 17 patients (50 %), whereas there was none in the remaining 50 %. There was no correlation between age...

Abstract
To find correlation between presence of PVD and incidence of different forms of AMD.
210 eyes of patients with AMD were examined. Fluorescein angiography determined type of AMD and ultrasound examination evaluated presence of PVD. Control group included 164 eyes of patients routinely admitted to the...

Abstract
VPA was significantly more common in eyes with macular holes than in controls or eyes with dry AMD, lamellar holes, or macular pucker. Intraretinal cystoid spaces were found in all eyes with macular holes with VPA. When present in macular pucker, VPA was frequently associated with intraretinal cysto...

Abstract
In our study, using indirect ophthalmoscopic exploration, we identified eleven patients with at least one retinal tear. HRA-II combined with the Staurenghi SLO 230 lens was capable of detecting 100% of these lesions. In addition, by means of this technology, we identified dark retinal zones that cor...

Abstract
Proliferative vitreoretinopathy in the inferior retina remains clinically challenging. Heavier-than-water intraocular tamponades have been developed to improve inferior tamponading properties. The parameters of an optimal intraocular tamponade are defined and the influences of the specific gravity,...

Abstract
We describe the advantages of the heavy silicone oil endotamponade and our own clinical experiences with Densiron(R) 68. The use of heavy silicone oils turned out to be quite convenient, leading for example to shorter tamponade times, easy handling of the oil, no need for uncomfortable prone-positio...

Abstract
In macular hole surgery, good to excellent anatomic and functional results have been reported using heavy tamponades with primary closure rates of up to 100 % of the cases. In reoperations of reopened macular holes, the reported success rates were between 60 % and 100 %. In the group of patients wit...

Despite major improvements of vitreo-retinal surgical techniques proliferative vitreoretinopathy (PVR) remains a major challenge. Surgical therapy alone may not be sufficient in complicated cases of PVR. A combination of standard techniques such as pars plana vitrectomy with a vitreous substitute an...

Abstract
Vitreous surgery has various physiological and clinical consequences, both beneficial and harmful. Vitrectomy reduces the risk of retinal neovascularization, while increasing the risk of iris neovascularization, reduces macular edema and stimulates cataract formation. These clinical consequences may...

Abstract
In contrast to immersion fixation, perfusion with either NBF/CPC or AEF/CPC maintained vitreous adherence to the ILL during histological processing. NBF/CPC proved best for highlighting intralaminar structure and for labeling type II collagen in the CV, particularly with antigen retrieval. AEF/CPC c...

Abstract
Scanning electron microscopy results showed that PVD did not occur at all with hyaluronidase alone (Group A, 0 of 10) and balanced salt solution alone (Group D, 0 of 10). Partial PVD was found in all eyes treated with plasmin alone (Group B, 10 of 10), whereas complete PVD was present in most but no...

A total of 289 eyes from 215 patients were examined. Of the eyes examined, 77.5% presented with findings in the vitreous cavity and the posterior pole. A posterior vitreous detachment with no other complications was observed in 47.4% of the eyes. The remaining 30.1% presented with eye diseases that...

Abstract
The vitreous pocket is a disc-shaped liquefied lacuna spreading anterior to the optic disc and macular region, which is surrounded by a dense network of fibrils. In patients with partial PVD around the optic disc, the posterior wall was visualized as being composed of two plate-like structures with...

Abstract
Hyaloid adhesion to the macula is associated with AMD, and frequently causes VMT in eyes with CNV. Tractional forces may antagonize the effect of anti-VEGF treatment, and cause pharmacological resistance in a subpopulation of patients. Future studies are needed to define the role of vitreoretinal su...

Abstract
The incidence of retinal detachment increases after cataract extraction, but it decreases with improved surgical technique. Postoperative posterior vitreous detachment is a major promoter of retinal detachment after cataract surgery and is related to onset of most retinal tears leading to retinal de...

Abstract
The SD OCT with 3-D image reconstruction provided unprecedented visualization of VMT and idiopathic ERM. The vitreous attachment to the macula can be subclassified into two subgroups, each having specific induced alterations in retinal anatomy. Most of the eyes with VMT had concurrent ERM, whereas s...

Posterior vitreous detachment was present in 37/44 eyes (84.1%) by ultrasound. Multiple foci of retinal contraction were detected in 20/44 eyes (45.5%) by coronal plane OCT/SLO. Intraretinal cysts were present in 6/9 (66.7%) eyes with three or four contraction centers as compared to 10/35 (28.6%) ey...

Abstract
Vitreomacular traction syndrome is an entity in which there is partial detachment of the posterior vitreous with persistent vitreomacular adhesion. This adherence may cause a maculopathy with vision loss. Using optical coherence tomography (OCT), the diagnosis is more frequent and more accurate. The...

Over eighty percent of recombinant human microPlg could be activated to active microPlm by rt-PA after 40 min incubation. Complete PVD was found at vitreous posterior pole of microPlm-treated eyes without morphological change of retina. Complete PVD of 25, 75, and 87.5% rabbit eyes was induced by 0....

Abstract
Vitreous degeneration is common in dogs and may be associated with cataract formation. Vitreous degeneration may be identified using B-mode ultrasonography and appears as multiple, small, motile, point-like echoes within the vitreous cavity. In humans, vitreous degeneration has also been observed in...

Abstract
The VA and macular thickness significantly improved after treatment. The pretreatment logMAR VA (R = 0.646; P < 0.0001), PVD development after tPA (R = -0.303; P = 0.025), and age (R = 0.255; P = 0.050) correlated with the logMAR VA at final visit. The greater improvement in logMAR VA was correlated...
