Encircling scleral buckling and silicone oil tamponade decrease the risk of recurrent retinal detachment.

Final visual outcome is greatly determined by the severity of the primary injury. On multivariate analysis, significant predictive factors of final VA were corneoscleral entrance wound, presence or absence of uveal prolapse, and development of retinal detachment.

Our findings suggest that HMGB1 activates inflammatory and angiogenic signaling pathways in diabetic retina mediated by RAGE.

Purpose To examine the expression of gelatinase B (matrix metalloproteinase-9) and the chemokines monocyte chemotactic protein-1 (CCL2/MCP-1) and stromal cell-derived factor-1 (CXCL12/SDF-1) in sympathetic ophthalmia (SO). Methods Five enucleated exciting eyes with a clinical diagnosis and typical histopathological findings of SO were studied by immunohistochemical techniques using a panel of monoclonal antibodies directed against gelatinase B, MCP-1, and SDF-1. In addition, a panel of monoclonal and polyclonal antibodies was used to characterize the composition of the inflammatory infiltrate. Results In all cases, the extensive uveal inflammatory infiltrate was organized as a diffuse infiltrate and as large granulomas consisting of epithelioid cells and multinucleated giant cells. CD20 þ B lymphocytes predominated in the diffuse infiltrate and CD3 þ T lymphocytes were few. The monocyte/macrophage marker CD68 was expressed in scattered inflammatory mononuclear cells and within granulomas and Dalen-Fuchs nodules. Most of the inflammatory cells were HLA-DR þ . Immunoreactivity for gelatinase B, MCP-1, and SDF-1 was observed in cells within granulomas and in scattered epithelioid cells. Immunoreactivity for MCP-1 was noted in retinal pigment epithelial cells. Endothelial cells of choriocapillaries showed weak immunoreactivity for SDF-1. Conclusions Gelatinase B, MCP-1, and SDF-1 might have a pathogenic role in the recruitment of leucocytes into the eye in SO.

Circulating fibrocytes may function as precursors of myofibroblasts in PVR membranes.

Ocular involvement in Behçet disease (BD) is characterized by recurrent inflammatory attacks and spontaneous resolution of acute inflammatory signs. Both frequency and severity of uveitis attacks determine the magnitude of irreversible damage to intraocular structures and long-term visual prognosis. Recurrent attacks of occlusive retinal vasculitis lead to vision-threatening complications such as cystoid macular edema, retinal neovascularization, optic atrophy and retinal atrophy. This manuscript updates about the role of various drugs in the management of BD, discussing corticosteroids, disease modifying immunosuppressive drugs, and finally biologicals (anti-TNF-blocking agents and alpha interferon) which seem to be superior compared to all other available drugs in preventing loss of vision. Also recent findings from new biologicals will be summarized, and especially the role of these drugs in children will be discussed in detail. The authors suggest that at least moderate to severe retinal involvement should become treated with biologicals whenever available.
