[Intraocular pressure during operations using the heart-lung machine (author's transl)]

The results of the investigations reported here show that contrary to expectations, the drop in mean arterial blood pressure (up to 57 mm Hg) during extracorporal circulation does not result in a simultaneous drop in intra-ocular pressure. Other factors, affect intra-ocular pressure during extracorporal circulation, causing it to rise. Postoperative studies of vision led to the conclusion that the elevations of intraocular pressure measured during extracorporal circulation with the heart-lung machine do not adversely affect ocular function.
