Anterior chamber tube shunt to an encircling band in the treatment of neovascular glaucoma

Ophthalmology. 1982 Oct;89(10):1188-94. doi: 10.1016/s0161-6420(82)34671-0.


A new procedure for neovascular glaucoma that has reduced intraocular pressure (IOP) significantly and has caused relatively few postoperative complications is introduced. Aqueous is shunted to the reservoir of an encircling no. 20 silicone band from which fluid is postulated to diffuse into the orbit. The anterior chamber tube shunt to an encircling band (ACTSEB) procedure was conducted in 19 eyes with neovascular glaucoma. After surgery 18 of the 19 eyes (95%) followed for periods ranging between five and 26 months (mean: 59 weeks) had controlled IOP using less than or equal to 20 mm Hg as normal, and one eye had partial control (eye 9) at 26 mm Hg. Despite the preoperative use of atropine sulfate, timolol maleate, acetazolamide, and 20% mannitol, the patients' average preoperative IOP was 54.1 mm Hg. After surgery the average IOP fell, dramatically, to 16.2 mm Hg. The mean change in IOP was 37.9 +/- 9.8 (SD). This change is statistically significant by the paired t-test, P less than 0.01. Minimal postoperative medications were required for pressure control. Postoperative complications included hyphema (21%), prolonged flat chamber (74%), localized peripheral lens opacity (5%), localized corneal opacity (5%), and possible acceleration of progressive cataract formation (25%). Results of current surgical procedures used to manage neovascular glaucoma are compared to the ACTSEB results.
