Twenty-six patients developed shallow anterior chamber (AC) within 8 weeks following surgery (cases). They were compared with 39 randomly selected controls (no shallow AC post AGV). HP (IOP spike &gt;21 mmHg), use of ocular hypotensive medications, and other associations were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Incidence of shallow AC post AGV was 7% (95% confidence interval [CI] 4, 9). The onset of shallow AC was 3 \u00b1 2.1 days and resolved within 6 \u00b1 4.7 days. Hypotony (12 [47%] vs. 1 [2.5%],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      0.0001) and choroidal detachment (CD; 7 [27%] vs. 3 [8%],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      0.03) were more common in cases compared to controls.
