Abstract
Objective To evaluate the clinical effect of lentectomy and vitrectomy combined with Ahmed glaucoma valve for secondary glaucoma with lens displacement.Methods The data in 32 cases(32eyes)of secondary glaucoma with traumatic lens displacement were analysed retrospectively.The routine operation of lentectomy and vitrectomy were done,combined with Ahmed glaucoma valve implanting in the superior temporal Tenon' s Capsule.Visual acuity,intraocular pressure and complication were observed preoperatively and postoperatively.Results The corrected visual acuity of 28 eyes were improved,the visual acuity of 4 eyes were constant postoperatively after 6 months.The average intraocular pressure was(39.58 +15.84)mmHg preoperatively,(9.66 ± 2.84)mmHg 3 days after surgery,(11.50 ± 3.41)mmHg in 1week,(13.36 ± 2.42)mmHg in 1 month,(15.80 ± 3.80)mmHg in 6 months,the average intraocular pressure was descended noticeably.The predominant complications were hyphema,shallow anterior chamber,drainage tube blocking,filtered bleb scarring.Conclusion Lentectomy and vitrectomy combined with Ahmed glaucoma valve is a kind of operation ideally for complex traumatic glaucoma caused by lens displacement,with lower postoperative intraocular pressure and preserving visual function.
