A control eye was time matched for each eye that underwent reoperation.<h4>Results</h4>The reoperation rate within 180 days was 16 of 151 (10.6%) for valved and 25 of 206 (12.1%) for non-valved tube shunts and at any time postoperatively was 31 of 151 (20.5%) for valved, and 47 of 206 (22.8%) for non-valved tube shunts.
