A randomized, prospective study on the use of sodium hyaluronate (Healon) in trabeculectomy

Abstract

The effect of injecting sodium hyaluronate (Healon) before fistulization in trabeculectomy was investigated in a prospective, randomized study of 107 consecutive eyes. Fifty-two eyes were operated on with the viscoelastic and 55 without. An early postoperative intraocular pressure (IOP) peak of 21 mm Hg or more occurred in 27% of the study eyes versus 17% of the control eyes, an insignificant difference. The mean peak IOPs of the study and the control eyes did not differ significantly (29.8 +/- 9.0 mm Hg versus 32.7 +/- 10.2 mm Hg), nor did the mean IOPs and the need for glaucoma medications 1 month after surgery. Shallow/flat anterior chamber and choroidal detachment were equally frequent in both groups, but hyphema occurred significantly more often in the study group (40%) than in the control group (18%).
