PURPOSE: To report a patient with symptomatic intraocular pressure (IOP) elevation in an eye with neovascular glaucoma (NVG) during hemodialysis. METHODS: Case report. RESULTS: Recurrent episodes of severe ocular pain and elevated IOP in the NVG eye were noted during hemodialysis in a 29-year-old man. The patient was recently diagnosed at our ophthalmology clinic with NVG due to central retinal vein occlusion. IOP was temporarily controlled after the Ahmed valve implantation. However, after the fibrous membrane developed and occluded the tip of the Ahmed valve, IOP elevation during hemodialysis recurred. Further treatments with intravenous mannitol, oral carbonic anhydrase inhibitor, topical antiglaumatic agents and subconjunctival 5-fluorouracil (5-FU) injections all failed to control relapsing pain and IOP elevation. Eventually, evisceration and hydroxyappatite implantation were performed. CONCLUSIONS: Physicians must be alert to the possibility of IOP elevation in glaucomatous eyes during hemodialysis.

BACKGROUND: Micro computed tomography (CT) is rapidly developing as an imaging tool, especially for mice, which have become the experimental animal of choice for many pulmonary disease studies. We evaluated the usefulness of micro CT for evaluating lung fibrosis in the murine model of bleomycin-induced lung inflammation and fibrosis. METHODS: The control mice (n=10) were treated with saline. The murine model of lung fibrosis (n=60) was established by administering bleomycin intra-tracheally. Among the 70 mice, only 20 mice had successful imaging analyses. We analyzed the micro CT and pathological findings and examined the correlation between imaging scoring in micro CT and histological scoring of pulmonary inflammation or fibrosis. RESULTS: The control group showed normal findings on micro CT. The abnormal findings on micro CT performed at 3 weeks after the administration of bleomycin were ground-glass opacity (GGO) and consolidation. At 6 weeks after bleomycin administration, micro CT showed various patterns such as GGO, consolidation, bronchiectasis, small nodules, and reticular opacity. GGO (r=0.84) and consolidation (r=0.69) on micro CT were significantly correlated with histological scoring that reflected pulmonary inflammation (p<0.05). In addition, bronchiectasis (r=0.63) and reticular opacity (r=0.83) on micro CT shown at 6 weeks after bleomycin administration correlated with histological scoring that reflected lung fibrosis (p<0.05). CONCLUSION: These results suggest that micro CT findings from a murine model of bleomycin-induced lung fibrosis reflect pathologic findings, and micro CT may be useful for predicting bleomycin-induced lung inflammation and fibrosis in mice.
