Purpose The purpose of this study was to evaluate the dispersion of intravitreally injected solutions and investigate the influence of varying injection techniques. Methods This was a prospective study using enucleated porcine eyes and ultra-high-resolution computed tomography (UHRCT) scanning to visualize iomeprol intravitreal dispersion. Sixty eyes were divided over 12 different groups acco...

PURPOSE To explore immunological mechanisms in the pathogenesis of proliferative vitreoretinal diseases, we measured the concentration of interleukin-6 in the vitreous body and serum from patients with proliferative diabetic retinopathy (PDR), proliferative vitreoretinopathy (PVR), and premacular fibrosis. To evaluate immunological etiology, interleukin-6 levels in each disease were compared wi...

UNLABELLED INTRODUCTION Valsalva retinopathy may occur as a sudden, dramatic loss of central vision due to the premacular location of the haemorrhage. It has been described in different clinical settings, and there are several options for its treatment. CASE PRESENTATIONS We present the cases of six patients with sudden visual acuity loss caused by Valsalva retinopathy, treated in our hosp...

AIMS To study the clinical properties of double vital staining in premacular fibrosis, facilitating complete removal of all epiretinal tissue. METHODS In a two step surgery, the epiretinal pucker was removed after staining with trypan blue, whereafter the inner limiting membrane was peeled after staining with infracyanine green. RESULTS In all 30 patients, a separate epiretinal layer and in...

OBJECTIVE To resolve the controversy surrounding the shape and relationship of posterior vitreous spaces by characterizing the connections between the premacular bursa, the area of Martegiani, and Cloquet's canal. DESIGN Comprehensive posterior vitreous maps were created using swept-source optical coherence tomography (SS OCT) in a cross-sectional study. PARTICIPANTS The posterior vitreous ...
