| 【 要旨 】 | 透析により眼圧が上昇する場合がある．不均衡症候群の一病態と考えられ，房水流出障害のある眼に，透析，とくに血液透析で不均衡を生じると，眼内に流入してきた水が十分流出できなくなるため眼圧が上昇すると推測される．非透析時に正常の眼圧が，透析時のみ上昇し，網膜神経線維が障害される，すなわち透析が原因の緑内障といえる病態が存在している可能性がある． 緑内障を合併した眼では，房水流出障害を伴っているため，透析により眼圧がさらに上昇して，病態の進行を早めている可能性がある． 治療は，房水流出障害を改善するか，不均衡を消失させる透析方法に変更することであるが，前者により根本的な治療が可能と思われる． |

| [ Summary ] | Intraocular pressure may increase, due to the disequilibrium syndrome, during dialysis. It is thought that disequilibrium of electrolytes during dialysis, especially during hemodialysis, disturbs fluid outflow from the eye, with decreased aqueous outflow, causing an increase in intraocular pressure. Increases in intraocular pressure which occur only during dialysis,will cause injuries to the retinal nerve fibers. This pathological condition may be considered to be, dialisis-induced glaucoma. High intra ocular pressure caused by glaucoma results from decreased aqueous outflow. During dialysis, intra ocular pressure may further increase, resulting in the deterioration of pathological conditions. Treatment strategies are, 1) improvement of decreased aqueous outflow and, 2) use of dialysis methods without the disequilibrium effect. The former strategy can create the fundamental solution to this problem. |
