From: Comparison of surgical outcomes of trabeculectomy, Ahmed shunt, and Baerveldt shunt in uveitic glaucoma

  Total Trabeculectomy Ahmed Baerveldt p value
  n = 147 eyes n = 17 eyes n = 22 eyes n = 108 eyes  
IOP (mmHg), M (range) 12 (1–33) 10 (1–25) 16 (8–28) 12 (5–33) 0.015*
Visual acuity (logMAR), M (range) 0.7 (0–3) 0.4 (0–3) 1 (0–3) 0.7 (0–3) 0.14*
Number of topical glaucoma medications, M (range) 2 (0–4) 0 (0–3) 2 (0–4) 2 (0–4) 0.098*
On systemic glaucoma medications, % (n) 7 (10) 6 (1) 9 (2) 6.5 (7) 0.86
Number of topical anti-inflammatory medications, M (range) 1 (0–3) 1 (0–2) 1 (0–2) 1 (0–3) 0.77*
On systemic immunosuppressants, % (n) 10 (14) 6 (1) 2 (3) 9 (10) 0.65§
IOP reduction (mmHg), M (range) 22 (5–75) 22 (11–47) 24 (7–40) 21 (5–75) 0.56*
% IOP reduction, M (range) 65 (26–100) 69 (41–97) 65 (21–81) 64 (40–89) 0.43*
Change in visual acuity (logMar), M (range) 0 (− 3–2) − 0.1 (− 1–2) 0 (− 2–2) 0 (− 3–2) 0.52*
Lost > 2 lines in visual acuity, % (n) 25 (36) 6 (1) 31 (7) 26 (28) 0.14§
Cataract surgery during follow up period, % (n) 5 (7) 0 (0) 5 (1) 6 (6) 1
Failure, % (n) 4 (6) 12 (2) 14 (3) 0.9 (1) 0.0063
  1. Failure was defined as postoperative intraocular pressure greater than 21 mmHg or less than 5 mmHg, < 20% IOP reduction, reoperation, or loss of light perception
  2. IOP intraocular pressure, logMAR logarithm of minimum angle of resolution
  3. *Kruskal-Wallis test; Fisher’s exact test; §chi-squared test
