When vitrectomy is performed in eyes that have undergone glaucoma surgery, the site of sclerotomy often overlaps with the previous glaucoma operation site. It can lead to serious complications such as postoperative hypotony, leakage, and/or infection. Our technique involves modification of surgeon's position and two sclerotomy sites 45° away from the original position, with an infusion cannula inserted infranasally to avoid damage to the glaucoma drainage implant or filtering bleb. The modified approach was applied to seven eyes with various indications. Vitrectomy was successfully completed, and there were no sclerotomy site complications, leakage, or hypotony in any case. Good intraocular pressure control was maintained throughout the postoperative course in all cases.

PURPOSE: To investigate whether subfoveal choroidal thickness, measured using enhanced depth imaging optical coherence tomography (EDI-OCT), is an indicator of subclinical ocular or systemic inflammation in eyes with Behçet disease (BD) without active ocular inflammation. METHODS: A retrospective analysis was used to examine clinical features of non-uveitic patients with BD (NUBD group), patients with a previous history of Behçet uveitis in an inactive state (IUBD group), and healthy controls were evaluated from October 2014 to September 2015. Subfoveal choroidal thickness was measured using EDI-OCT. RESULTS: The NUBD group included 46 eyes in 24 patients; the IUBD group included 16 eyes in 11 patients; and the control group included 35 eyes in 23 individuals. The mean subfoveal choroidal thicknesses differed significantly among these groups. Choroidal thickness was significantly greater in the NUBD (310.5 ± 81.0 µm) than in the IUBD (263.1 ± 56.6 µm, p = 0.013) and control (256.9 ± 67.9 µm, p = 0.002) groups. The disease activity score was significantly higher in the NUBD than in the IUBD group (p < 0.001), while the use of cyclosporine was significantly associated with choroidal thickness in eyes with NUBD (p = 0.039). CONCLUSIONS: Subfoveal choroidal thickness, as measured by EDI-OCT, may be a clinical indicator of subclinical ocular inflammation and systemic inflammation in BD patients without active ocular inflammation.

BACKGROUND: Idiopathic pulmonary fibrosis involves irreversible alveolar destruction. Although alveolar epithelial type II cells are key functional participants within the lung parenchyma, how epithelial cells are affected upon bleomycin (BLM) exposure remains unknown. In this study, we determined whether BLM could induce cell cycle arrest via regulation of Schlafen (SLFN) family genes, a group of cell cycle regulators known to mediate growth-inhibitory responses and apoptosis in alveolar epithelial type II cells. METHODS: Mouse AE II cell line MLE-12 were exposed to 1–10 µg/mL BLM and 0.01–100 µM baicalein (Bai), a G1/G2 cell cycle inhibitor, for 24 hours. Cell viability and levels of pro-inflammatory cytokines were analyzed by MTT and enzyme-linked immunosorbent assay, respectively. Apoptosis-related gene expression was evaluated by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). Cellular morphology was determined after DAPI and Hoechst 33258 staining. To verify cell cycle arrest, propidium iodide (PI) staining was performed for MLE-12 after exposure to BLM. RESULTS: BLM decreased the proliferation of MLE-12 cells. However, it significantly increased expression levels of interleukin 6, tumor necrosis factor α, and transforming growth factor β1. Based on Hoechst 33258 staining, BLM induced condensation of nuclear and fragmentation. Based on DAPI and PI staining, BLM significantly increased the size of nuclei and induced G2/M phase cell cycle arrest. Results of qRT-PCR analysis revealed that BLM increased mRNA levels of BAX but decreased those of Bcl2. In addition, BLM/Bai increased mRNA levels of p53, p21, SLFN1, 2, 4 of Schlafen family. CONCLUSION: BLM exposure affects pulmonary epithelial type II cells, resulting in decreased proliferation possibly through apoptotic and cell cycle arrest associated signaling.
