最近10年間に経験した,鈍的眼外傷に続発する高眼圧症88例を対象とし,前房出血と水晶体脱臼の合併,受傷後早期のangle recessionの範囲,受傷時年齢に着目して,眼圧の予後予測の目的で統計的検討を行った.
結果は(1)受傷後早期に減圧目的の手術を受けた症例に,有意に高率に水晶体脱臼が合併していた.(2)受傷後長期経過例の眼圧コントロールは,受傷後早期の前房出血・水晶体脱臼の有無,anglerecessionの範囲とは有意な関係はなかった.(3)受傷後長期経過例の眼圧コントロールは受傷時年齢が高いほど不良であった.
したがって,受傷後早期には水晶体脱臼の合併の有無が,長期経過後には受傷時の年齢が,眼圧の予後予測に重要であると思われた.
We evaluated a consecutive series of 88 cases who developed ocular hypertension. These cases were a part of a larger series of 1478 cases with ocular contusion seen by us during the foregoing 10- year period. We analyzed these cases by the chi-square test with a view to detect risk factors that might necessitate surgicaltreatment of ocular hypertension and that might influ-ence the long-term prognosis.
As risk factors that would necessitate surgery, we detected the following items in the decreasing order of significance : lens dislocation associated by hyphema, simple lens dislocation, simple hyphema, and absence of lens dislocation or hyphema. The longterm prognosis of intraocular pressure was independent of hyphema, lens dislocation or degree of the chamber angle recession. The control of intraocular pressure over a longterm basis was significantly poor in aged subjects and was good in younger ones. Rinsho Ganka (Jpn J Clin Ophthalmol) 40(6) : 625-628, 1986
