PURPOSE: To investigate whether vascular endothelial growth factor, soluble intercellular adhesion molecule-1 (sICAM-1), and pigment epithelium-derived factor are associated with serous retinal detachment (SRD) secondary to branch retinal vein occlusion. METHODS: The subjects were 44 branch retinal vein occlusion patients with macular edema and 16 controls. Patients were divided into 2 groups by optical coherence tomography findings, that is, 18 patients with SRD and 26 with cystoid macular edema. The area of capillary nonperfusion was measured with fluorescein angiography and Scion Image software. Vitreous fluid samples obtained during pars plana vitrectomy were examined by enzyme-linked immunosorbent assay. RESULTS: The incidence of major branch retinal vein occlusion was significantly higher in SRD patients (17/18, 94%) than in cystoid macular edema patients (15/26, 58%, P = 0.007), while the nonperfused retinal area was significantly larger in SRD patients (P = 0.006). Vitreous fluid levels of vascular endothelial growth factor and soluble intercellular adhesion molecule-1 (sICAM-1) showed a significant increase across the 3 groups (control group, cystoid macular edema group, and SRD group) (Ptrend < 0.001 and Ptrend < 0.001, respectively), while the pigment epithelium-derived factor level showed a significant decrease across the 3 groups (Ptrend < 0.001). CONCLUSION: An excessive increase of vascular permeability secondary to upregulation of vascular endothelial growth factor and soluble intercellular adhesion molecule-1 (sICAM-1) along with downregulation of pigment epithelium-derived factor may contribute to the development of SRD in BRVO patients.

Background: The association of inflammatory factors and the aqueous flare value with macular edema in central retinal vein occlusion (CRVO) patients remains unclear. We investigated the relations between the aqueous flare value and vitreous levels of vascular endothelial growth factor (VEGF), soluble intercellular adhesion molecule-1 (sICAM-1), and interleukin-6 (IL-6) in patients with CRVO and macular edema or patients with idiopathic macular hole (MH). Methods. In 38 patients who underwent unilateral vitrectomy (21 CRVO patients and 17 MH patients), vitreous samples were obtained during vitrectomy to measure VEGF, sICAM-1, and IL-6. Retinal ischemia was evaluated from capillary non-perfusion on fluorescein angiography, and the CRVO patients were classified into nonischemic or ischemic groups. Aqueous flare values were measured with a laser flare meter and macular edema was examined by optical coherence tomography. Results: The median aqueous flare value increased significantly across the three groups (MH group < nonischemic CRVO group < ischemic CRVO group). There was a significant correlation between the flare value and vitreous levels of VEGF, sICAM-1, and IL-6 in the CRVO group. The flare value was also significantly correlated with the severity of macular edema in the CRVO group. Conclusions: Inflammation and/or ischemia may increase vascular permeability and disrupt the blood-aqueous barrier by increasing levels of inflammatory factors in patients with CRVO and macular edema. © 2013 Noma et al.; licensee BioMed Central Ltd.
