Surgical outcomes of trabeculotomy combined with sinusotomy for juvenile glaucoma.

PURPOSE To evaluate the outcome of trabeculotomy combined with sinusotomy for juvenile glaucoma. METHODS We studied 16 patients (25 eyes) (age range, 11-50 years) with juvenile glaucoma for a minimum follow-up period of 1 year. We performed combined trabeculotomy and sinusotomy surgery in 13 juvenile glaucoma patients (18 eyes), and trabeculotomy alone in 6 patients (7 eyes). RESULTS The intraocular pressure (IOP) of the combined surgery group was 29.8 +/- 7.8 mm Hg before surgery and 15.6 +/- 3.0 mm Hg 1 year after surgery. The IOP of the trabeculotomy-alone group was 29.1 +/- 6.4 mm Hg before surgery and 15.4 +/- 2.4 mm Hg 1 year after surgery. A postoperative IOP spike that was higher than the preoperative IOP was recorded in 2 eyes of the combined surgery group and in 2 eyes of the trabeculotomy group. The combined surgery group consisted of 7 eyes with a previously failed glaucoma surgery, and 11 eyes having a first glaucoma surgery. The postoperative IOP in these 11 eyes was 15.5 +/- 2.8 mm Hg. CONCLUSION Trabeculotomy is very effective in lowering the IOP in patients with juvenile glaucoma. Sinusotomy does not play an important role in tension control.
