  • Abstract
  • Look Inside

We performed vitrectomy on 17 eyes, 16 patients, with proliferative diabetic retinopathy. All the eyes manifested active fibrovascular proliferation with tractional detachment of the macula. During treat-ment of the proliferative membrane, the infusion pressure was temporarily elevated to induce cessa-tion of blood flow in the central retinal artery. Infusion pressure of 82 to 105,mmHg resulted in practical hemostasis. The duration of hemostasis ranged from 0.9 to 16.5 minutes, average 4.1 min-utes. The retina became reattached in 16 eyes,94%. The visual acuity improved in 15 eyes, 88%. There was no instance of deterioration of visual acuity in the series. The present technique of hyper-infusion pressure resulted in better visualization of the membrane, prevention of perioperative complica-tions, shortening of duration of surgery and improvement in the surgical outcome. Eyes with proliferative diabetic retinopathy were found to tolerate ischemia for 10 minutes or longer.
