Abstract

Forty-six eyes with primary open-angle glaucoma(POAG) and 34 eyes which had previously undergone trabeculectomy for POAG were studied and the postural response of the intraocular pressure(IOP) compared with that of 80 normal eyes, In all groups the increment in IOP occurred when the subject changed from the sitting to the lying position. The pressure increment when changed from the sitting to lying position, averaged 2.4 mmHg in normal eyes, 3.6 mmHg in the group who were treated medically and 3.8 mmHg in the group who had undergone trabeculectomy. There was greater postural response in primary open-angle glaucoma patient compared to normal subject. And also there was no statistically significant difference of postural response in intraocular pressure between the group who were treated medically and the group who had undergone trabeculectomy. It is suggested that abnormal postural response of intraocular pressure in POAG appears to be retained and to be unaffected in those eyes which had undergone trabeculectomy.
