PURPOSE To show a case in which the shape of the fovea changed after an asymptomatic macular posterior vitreous detachment (PVD). METHODS The foveal shape was determined from the spectral-domain optical coherence tomography (OCT) images before and after a spontaneous macular PVD. RESULTS A 66-year-old man with a unilateral macular hole in the right eye presented with a perifoveal PVD in the...

Purpose: To evaluate the efficacy of autologous plasmin in pediatric vitrectomy and to report the anatomic outcomes of autologous plasmin assisted pediatric vitrectomy Methods: In an interventional prospective study, Thirty-four pediatric patients with vitreoretinal disorders who needed vitrectomy during 2008 to 2010, included in the study. The patients were divided into two groups: the retinop...

BACKGROUND To report our findings in a patient with asteroid hyalosis (AH) who had a severe reduction of his visual acuity following cataract surgery. The vision was improved by vitreous surgery. CASE PRESENTATION The patient was an 81-year-old man. Following cataract surgery on his left eye, his decimal best-corrected visual acuity (BCVA) was markedly reduced from 0.2 to 0.02. A large number...

PURPOSE To identity anatomic risk factors involved in the onset of retinal complications causing decrease of visual acuity (VA) in the fellow eyes of highly myopic patients operated for retinal detachment with macular hole (RDMH). DESIGN Cohort study. PARTICIPANTS Ninety-eight patients (mean age, 51.5+/-8.0 years) with bilateral high myopia (mean myopia of the fellow eye, 20.4+/-5.5 diopter...

PURPOSE To demonstrate the efficacy of microplasmin in inducing posterior vitreous detachment (PVD) and to evaluate the human and the feline retina after treatment. METHODS Thirteen human donor eyes were injected with 62.5, 125, or 188 micro g microplasmin. The 13 fellow eyes received balanced salt solution. Four of the microplasmin-treated eyes received an additional intravitreal gas injecti...

Purpose. To objectively detect true posterior vitreous cortex (PVC) adhesion status using a commercially available swept-source OCT device (DRI OCT-1, Atlantis(©)). Material and Methods. Case report, review of the literature, and methodical discussion of concepts to improve OCT-guided PVC imaging. Results. Standard OCT imaging misdiagnosed PVC adhesion status as totally detached in this case re...

PURPOSE To determine prevalence and associations of incomplete posterior vitreous detachment (PVD). METHODS The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6±9.8 years (range: 50-93 years). A detailed ophthalmic examination was performed including spectral-domain optical coherence tomography (SD-OCT). Incomplete PVD was differentiate...

Clinical features of epiretinal membranes were examined in 22 eyes of 13 patients with Terson syndrome who were treated with pars plana vitrectomy. The shape and localization of the epiretinal membranes were intraoperatively evaluated and correlated with the presence or absence of posterior vitreous detachment (PVD). Patients with complete PVD, but with no membrane found during surgery, were fo...

The paper presents a review of the sequence of events of posterior vitreous detachment (PVD), vitreomacular adhesion (VMA), vitreomacular traction (VMT), and macular hole (MH) from their pathophysiological aspects, clinical features, diagnostic implications, and current management strategies. A treatment algorithm to be used in clinical practice in patients with VMA, VMT, and MH based on the pr...

It is well known that the vitreous forms 80% of the ocular body and consists of water (98%) and a network of collagen fibrils and hyaluronic acid (2%). Thus, the vitreous is typically characterised as a transparent gel firmly attached to the retina. Vitreal transparency is key as it allows transmission of light through unobstructed media to the retina for visual stimulation. With age, the vitre...
