隔日に視野の変動する緑内障の2例—第2報視野の変動と眼圧，全身血圧，眼底血圧の関係

Two cases of simple glaucoma with daily variation of isopters.(Report 2): The correlation between the variation of visual field loss and intraocular pressure, blood pressure of the brachial artery and the central retinal artery.

I．緒言

　第1報（予報）で述べた如く，一日おきに視野の拡がる日と狭くなる日を訴える緑内障の症例は，内外に未だその報告を見ない。私は視野狭窄高度の末期緑内障で，手術及び薬剤で治療後，視野が隔日に広くなり，狭くなるのを自覚する様になつた2例を経験したので，眼圧日差，全身血圧，眼底血圧，脈膊，呼吸等と，視野変動の関係を調べた。症例の所見，治療，経過については第1報で述べたので極く大略のみ記す。

　症例1は32歳女子，症例2は54歳男子，何れも両眼眼圧亢進著明，流出率極小，視野，眼底変化強く，狭隅角で，全身血圧低く，眼圧全身血圧比が小さい。視力は第1例は右正常，左0，第2例は右50cm手動，左0である。

Two patients with simple glaucoma had isopters variations every other day-one day extensive and contracted the next. The author measured the diurnal variations in the intra-ocular pressure, systolic and diastolic blood pressure of the brachial artery and the central retinal artery, tonography, ocular rigidity, pulsation, respiration and isopters over a period of more than 10 days. The isopters extended most widely when the phasic varia-tion of ocular tension was great. In such days, the coefficient (the ratio of blood pre-ssure to intraocular pressure) increased marke-dly, when intraocular tension feel rapidlyand noticably.
