Background: Proliferative diabetic retinopathy (PDR) is a common visual threatening ocular disease, patients with nonclearing vitreous hemorrhage (VH), tractional retinal detachment (RD), or extensive fibrovascular proliferation are always in need for surgical treatment. Although several studies reported better surgical outcome in patients underwent surgery after anti-VEGF injection, the effect of anti-VEGF pretreatment for small gauge vitrectomy in PDR patients remains to be elucidated.

Objectives: The objective of the study was to evaluate the benefits of preoperative anti-VEGF treatment in small gauge vitrectomy for PDR patients.

Aim: To explore the association of single nucleotide polymorphisms (SNPs) in the gene region with the susceptibility to Behcet's disease (BD) in a Chinese Han population.

Methods: A total of eight SNPs in the candidate gene region (rs11792633, rs7025417, rs10975519 and rs1048274 in ; rs2310220, rs12712142, rs13424006 and rs3821204 in ) were genotyped in783 BD patients and 701 healthy controls by the Sequenom Mass Array iPLEX platform.

Results: A statistically significant association was observed between rs12712142 and BD patients.

To evaluate and compare the efficacy and safety of interferon alpha-2a (IFN-α2a) and cyclosporine-A (CsA) in patients with refractory Behçet's uveitis (BU). In this 12-month randomized, controlled, prospective trial, 26 participants (44 eyes) completed the study. Patients were randomly allocated to the IFN-α2a or CsA groups.

Purpose: Changes of choroidal circulation throughout the disease course of Vogt-Koyanagi-Harada (VKH) disease and the clinical significance remain unclear. Choriocapillary vascular density (CC VD) measured by optical coherence tomography angiography (OCTA) were compared in different disease stages of VKH and its correlation with other parameters was analyzed, aiming to explore their clinical relevance.

Methods: This is a retrospective case series.

Interleukin (IL)33, a member of the IL1 superfamily, functions as a nuclear factor and mediates biological effects by interacting with the ST2 receptor. Recent studies have described IL33 as an emerging pro-inflammatory cytokine in the immune system, and / gene polymorphisms have been implicated in the pathogenesis of various immune diseases. However, the underlying mechanisms of in Behcet's disease (BD) remain to be defined.

Purpose: To analyze the retinal capillary vascular density (VD) as quantified by optical coherence tomography angiography (OCTA) in patients with pediatric uveitis.

Methods: OCTA images of 32 pediatric uveitis patients and 30 normal controls (NC) were obtained retrospectively. The foveal avascular zone (FAZ) area, VDs in the superficial capillary plexus (SCP) and deep capillary plexus (DCP), the central macular thickness (CMT), and subfoveal choroidal thickness (SFCT) were analyzed and compared between active and quiescent uveitic eyes, contralateral eyes and NC eyes.

: To analyze quantitative OCT-angiography (OCTA) measurements of Vogt-Koyanagi-Harada (VKH) disease at different disease stages.: OCTA scans of 110 VKH patients in acute uveitic, convalescent and chronic recurrent stage were reviewed; posterior uveitis recurrent cases were excluded. Superficial and deep capillary plexus (SCP and DCP) vascular densities (VD) and subfoveal choroidal thickness (SFCT) were compared.

Background: Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) that often affects men over the age of 60. Systemic metastasis of MCL to eyes is rare and intraocular involvement is even rarer, which usually affects the choroid and iris. To the best of our knowledge, ciliary body metastasis of systemic MCL has not been reported.

Purpose: To investigate the chemokine and adhesion molecule profiles in aqueous humor (AH) of eyes with inactive uveitis and their correlations with inflammation relapse after cataract surgery.

Methods: Patients with inactive uveitis who underwent cataract surgery between July 2014 and January 2016 at our center were included. Undiluted AH samples (100-120 µl) were obtained through lateral corneal incisions during surgery, and concentrations of monocyte chemoattractant protein 1 (MCP-1/CCL2), macrophage inflammatory protein 1 (MIP-1), interleukin 8 (IL-8), regulated on activation, normal T cell expressed and secreted (RANTES/CCL5), soluble vascular cell adhesion molecule (sVCAM) and soluble intercellular adhesion molecule (sICAM) were measured by cytometric bead array (BD Bioscience, San Jose, CA).

Purpose: To address the visual prognosis and associated predictors of phacoemulsification and intraocular lens implantation in different uveitis entities in Han Chinese.

Methods: A retrospective review of the uveitis patients who underwent phacoemulsification and intraocular lens implantation in our center between 2004 and 2014.

Results: The 158 patients (226 eyes) included anterior uveitis (45 eyes), posterior/pan-uveitis (61 eyes), Vogt-Koyanagi-Harada disease (79 eyes) and Behçet disease (41 eyes).
