A 51-year-old male who had suffered from right eye rhegmatogenous retinal detachment with proliferative vitreoretinopathy received surgical treatments which included the following procedures: lens extraction, scleral buckle, vitrectomy, membrane peeling, photocoagulation, and silicone oil injection. The presenting visual acuity of the right eye was light perception. Slit-lamp examination revealed corneal opacity without a visible fundus. B-scan ultrasonography revealed retinal detachment. Endoscope-assisted vitrectomy was then performed in December 2014...

BACKGROUND: Pars plana vitrectomy is the only treatment for advanced proliferative diabetic retinopathy (PDR). However, vitrectomy is not always successful despite current progress in vitreoretinal surgical techniques. The aim of our study was to investigate whether the vitreal concentrations of MCP-1, IL-6, IL-8, and VEGF are elevated after unsuccessful vitrectomy in patients with PDR and to investigate whether the altered levels of these cytokines are associated with the cause for the reoperation...

BACKGROUND: For intraocular surgery, most authors recommend general anaesthesia including intubation and neuromuscular blockade to avoid complications by patient movements. However, anaesthesia using a laryngeal mask and avoidance of muscle relaxants is common clinical practice. Purpose of this prospective observational study was to compare the incidence of eye movement and deviation of the eye axis during general anaesthesia adjusted to minimal alveolar concentration (MAC) for pars plana-vitrectomy (PPV) using a laryngeal mask without neuromuscular blockade (LM) versus endotracheal intubation and neuromuscular blockade (INT)...

Pathologic myopia is associated with degenerative changes of the globe, especially at the posterior pole. Eyes affected by pathologic myopia have higher odds to undergo posterior segment surgery and, in those eyes, vitreoretinal surgery is challenging. Many practical tips and tricks can make the surgical procedures simpler, significantly preventing sight-threatening intra- and post-operative complications. Moreover, novel surgical techniques and technological advancements (i.e. ad-hoc instrumentation, minimally invasive vitreoretinal surgery, filters, dye staining, intraoperative optical coherence tomography and 3-dimensional surgery) may play role in highly myopic eyes...

The eye and the ocular adnexae are rare sites for malignant non-Hodgkin lymphoma (NHL). Based on their anatomical location, intraocular lymphomas must be discerned from NHL of adnexal structures including conjunctiva, lacrimal gland, and orbit. Whereas the latter group mostly consists of indolent extranodal marginal zone B‑cell lymphomas of mucosa-associated lymphoid tissue (MALT) type or secondary manifestations of systemic NHL, most primary intraocular lymphomas are classified as diffuse large B‑cell lymphomas (DLBCL) and are considered a variant of primary DLBCL of the central nervous system...

BACKGROUND: Incontinentia pigmenti is a rare X-linked dominant syndrome caused by mutation in the NEMO/IKKgamma gene, and characterized by a spectrum of cutaneous, ocular, neurologic and dental abnormalities. In the eye, findings include retinal vascular non-perfusion, occasionally with traction retinal detachment, retinal fibrosis, and retinal pigment epithelium defects. These findings can resemble retinoblastoma, especially when vitreoretinal fibrosis produces leukocoria. CASE REPORT: A 2-month-old girl born full-term presented with leukocoria, suspicious for retinoblastoma...

Retinal gene delivery via intravitreal injection is hampered by various physiological barriers present in the eye of which the vitreoretinal (VR) interface represents the most serious hurdle. In this study, we present a retinal explant model especially designed to study the role of this interface as a barrier for the penetration of vectors into the retina. In contrast to all existing explant models, the developed model is bovine-derived and more importantly, keeps the vitreous attached to the retina at all times to guarantee an intact VR interface...

Proliferative vitreoretinal diseases such as diabetic retinopathy, proliferative vitreoretinopathy (PVR), and age-related macular degeneration are a leading cause of decreased vision and blindness in developed countries. In these diseases, retinal fibro(vascular) membrane (FVM) formation above and beneath the retina plays an important role. Gene expression profiling of human FVMs revealed significant upregulation of periostin. Subsequent analyses demonstrated increased periostin expression in the vitreous of patients with both proliferative diabetic retinopathy and PVR...
