INTRODUCTION Vitreous hemorrhage associated with retinopathy of prematurity is often seen in childhood, but adult onset without retinal break is rare. We describe a case of recurrent vitreous hemorrhage associated with regressed retinopathy of prematurity in a 47-year-old patient. CASE PRESENTATION A 47-year-old Japanese woman with a history of retinopathy of prematurity presented with a visu...

Purpose. To compare the stages of vitreous degeneration in patients with vitreomacular traction (VMT) and macular holes (MH). Methods. A retrospective study was performed analyzing stages of vitreous degeneration of eyes with VMT or MH using swept-source optical coherence tomography (SS-OCT) and spectral-domain optical coherence tomography (SD-OCT). An analogous review was performed on a contro...

increased vitreoretinal adhesion include lattice degeneration, some post-inflammatory lesions, areas of degenerative modelling, and some vitreous base lesions. These areas of increased adhesion may remain attached, even if the vitreous is detached elsewhere. Sebag and Balazs reported that the posterior vitreous cortex contained a round hole corresponding to the peripapillary attachment. The dia...

BACKGROUND Vitrectomy for symptomatic vitreous floaters carries significant risks. Justification of surgery is difficult, particularly in healthy eyes with normal visual acuity and without a posterior vitreous detachment. This is the first reported case of optical coherence tomography being utilized to objectively assess the impact of a vitreous opacity on the macula. CASE PRESENTATION A 37-y...

PURPOSE This study aimed to establish a method for testing Staphylococcus aureus in the vitreous of endophthalmitis with matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), which is simple, fast, and sensitive. METHODS S. aureus at different numbers was either mixed with homogenized vitreous or inoculated in porcine eyes for culturing, followed by homo...

Vitreous fluid specimens are often used in the Montgomery County Coroner's Office as a second matrix confirmation for both cocaine and opiate analyses. In this manuscript, calibration curves constructed for both vitreous and blood were used to quantify vitreous specimens to evaluate if any matrix effects occur when measuring vitreous specimens using a calibration curve in blood. Cases that scre...

Diagnosing a posterior vitreous detachment (PVD) is important for predicting the prognosis and determining the indication for vitreoretinal surgery in many vitreoretinal diseases. This article presents both classifications of a PVD by slit-lamp biomicroscopy and of a shallow PVD by optical coherence tomography (OCT). By biomicroscopy, the vitreous condition is determined based on the presence o...

PURPOSE To study the patterns of vitreous incarceration at sclerotomy sites by ultrasound biomicroscopy in patients subjected to valved or nonvalved small-gauge pars plana vitrectomy. METHODS A prospective comparative study of 88 eyes affected by epiretinal membrane and macular hole. Patients were divided into four groups: valved or nonvalved 23-gauge (16 eyes each) and valved or nonvalved 25...

Differences in protein content and composition between vitreous and floury endosperm were investigated using a number of different techniques. Differences in protein cross-linking between vitreous and floury endosperm were investigated using differential solubility, size exclusion chromatography (SEC), and analysis of sulfhydryl content and composition. Vitreous endosperm was found to have high...

The purpose of this paper is to report two cases of sarcoidosis with conflicting signs in which vitreous cytology was useful for supporting the diagnosis. Case 1 was a 56-year-old man who was referred with blurred vision, and was found to have iridocyclitis, vitreous opacities, and optic neuritis bilaterally. He also had a swelling of both mandibular glands. He received pulsed corticosteroid th...
