Blaxter于1955年做眼球加压试验(压出率),认为对诊断青光眼有一定的价值。作者为证实本试验的临床价值,对正常人50例100眼,青光眼127例173眼,除做压出率外并加做容积差和代偿值。结果正常眼中仅2眼可疑阳性,青光眼绝对期阳性率最高,单性青光眼次之,青光眼术后阳性率最低。本法简便易行,阳性率高,并可提示青光眼是否需要手术及术后房水流畅情况。对单性青光眼早期诊断及预示治疗是否稳定有一定的价值。 Blaxter in 1955 to do the ball pressure test (extrusion rate), that the diagnosis of glaucoma has some value. In order to confirm the clinical value of this trial, 50 eyes of 100 normal subjects and 127 eyes of 127 eyes of glaucoma were excluded. Results In normal eyes, only 2 eyes were suspicious positive, the absolute positive rate of glaucoma was the highest, followed by monogenic glaucoma, the lowest positive rate after glaucoma surgery. This method is simple, positive rate, and can prompt glaucoma surgery and postoperative aqueous fluid condition. Early diagnosis of unilateral glaucoma and predict whether the treatment has a certain value.
