BACKGROUND Diffuse large B-cell lymphoma is a clinically and molecularly heterogeneous disease. Gene expression profiling studies have shown that the tumor microenvironment affects survival and that the angiogenesis-related signature is prognostically unfavorable. The contribution of histopathological microvessel density to survival in diffuse large B-cell lymphomas treated with immunochemother...

Introduction: Ultrasound cycloplasty (UCP) is commercially available in Europe. It has been shown to have less side effects than its trans-scleral diode laser cyclophotocoagulation counterpart reducing intraocular pressure (IOP) refractory glaucoma patients.
 Case presentation: This retrospective case series followed seven patients treated with UCP for at the Ophthalmology Clinic, Hospital...
