PURPOSE Defensins are naturally occurring antimicrobial peptides. Recently the authors published evidence of defensin production by the human ocular surface. A study was undertaken to look for intraocular defensins that may account for unexplained antimicrobial activity of intraocular fluids. METHODS Reverse transcription-polymerase chain reaction (RT-PCR) was performed on human postmortem ci...

We present an experimental study of the vitreous motion induced by saccadic eye movements. A magnified model of the vitreous chamber has been employed, consisting of a spherical cavity carved in a perspex cylindrical container, which is able to rotate with a prescribed time law. Care has been taken to correctly reproduce real saccadic eye movements. The spherical cavity is filled with glycerol ...

Bone marrow-derived cells have been used in different animal models of neurological diseases. We investigated the therapeutic potential of mesenchymal stem cells (MSC) injected into the vitreous body in a model of optic nerve injury. Adult (3-5 months old) Lister Hooded rats underwent unilateral optic nerve crush followed by injection of MSC or the vehicle into the vitreous body. Before they we...

INTRODUCTION Endophthalmitis following penetrating eye injuries has a poor prognosis and presents a diagnostic and therapeutic challenge. The aim of reporting this case was to identify the causative organism of post-traumatic endophthalmitis due to retained iron foreign body and to highlight the importance of carrying out diagnostic investigations.

The presence of asteroid bodies in the vitreous, designated asteroid hyalopathy by Rodman, Johnson, and Zimmerman (i 96 I), is an interesting but rare condition of obscure aetiology. In spite of the presence of these vitreous opacities, there is hardly any deterioration in the acuity of vision, hence the paucity of available pathological material for study and analysis. Many diseases have been ...
