ABSTRACT
AIM: To evaluate the efficacy of Ahmed glaucoma valve implanting through the ciliary sulcus in the treatment of intraocular lens(IOL)glaucoma.METHODS: Retrospective case series study. The clinical data of 18 patients(18 eyes)with IOL glaucoma from February 2020 to February 2022 in Liuzhou Red Cross Hospital were collected. All patients underwent Ahmed glaucoma valve implanting through the ciliary sulcus. The visual acuity, intraocular pressure, corneal endothelial cell density, corneal endothelial cell loss rate and complications were observed before operation and 1, 3, 6 and 12mo after operation.RESULTS: The mean intraocular pressure before operation was 43.41±5.33 mmHg. The mean intraocular pressure at 1, 3, 6 and 12mo after operation were 12.11±3.26, 13.82±4.12, 13.54±3.83 and 15.80±4.35 mmHg respectively. The mean intraocular pressure at each follow-up point after operation was significantly lower than that before operation(F=203.40, P<0.01). The corneal endothelial cell density at each time point after surgery was lower than that before surgery(F=6.18, P<0.01), but there were no significantly differences in the density and loss rate of corneal endothelial cell at 1, 3, 6 and 12mo after surgery(P>0.05). Furthermore, the overall surgery success rate was 83%.CONCLUSIONS: Ahmed glaucoma valve implanting through the ciliary sulcus is safe and effective in the treatment of IOL glaucoma, and the damage to corneal endothelial cells is mild. The corneal endothelial cells density doesn't decrease with time after surgery.
