Ahmed glaucoma valve implantation with the tube placement in the ciliary sulcus: short-term results

Purpose To evaluate the clinical outcomes of pseudophakic/aphakic eyes with uncontrolled glaucoma that underwent Ahmed glaucoma valve implantation with the tube placement in the ciliary sulcus. Methods Medical records of the patients who underwent Ahmed glaucoma valve implantation through the ciliary sulcus, between December 2017 and June 2019, were reviewed retrospectively. Patients’ age, gender, glaucoma diagnosis, visual acuity, intraocular pressure levels, and complications were recorded. Results Forty-seven eyes of 43 patients with glaucoma were enrolled. The mean age was 54.5 ± 19.9 years (range, 7–88 years) at the time of surgery, and the mean postoperative follow-up period was 7.9 ± 3.4 months (range, 3–16 months). The mean preoperative intraocular pressure level was 35.2 ± 6.8 mmHg (range, 25–55 mmHg), and it was found as 15.6 ± 5.4 mmHg (range, 9–33 mmHg) at the last follow-up visit. Decrease in intraocular pressure level was statistically significant ( P
