Summary

This study will compare the effect of two intravenous solutions on eye pressure during spine surgery in the following groups: Group A - Lactated Ringer's replacement for blood loss and placebo eye drops Group B - Lactated Ringer's replacement for blood loss and brimonidine eye drops Group C - Albumin replacement for blood loss and placebo eye drops Group D - Albumin replacement for blood loss and brimonidine eye drops

Detailed description

Patients will be administered either brimonidine eye drops, or placebo eye drops, preoperatively, on the day of surgery and during surgery. Eye pressure will be measured before surgery, every 30 minutes throughout your surgery and every hour for 4 hours following surgery. Subjects will be evaluated before surgery and on days 5, 8, 15 after surgery. During these evaluations, the subject will be asked questions about recovery and his/her eyes will be checked by an ophthalmologist and vision will be tested.
