Caue analysis of detachment following suture fixation of posterior chamber intraocular lens implantation

Objective To report clinical characteristic on the retinal detachment following suture fixation of posterior chamber intraocular lens implantation.Methods We retrospectively reviewed the records of 14 patients (14 eyes),and analyzed background factors,intraoperative findings and surgical outcomes.Re-sults Retinal detachment occurred from 20 to 204 days (mean 96.5 days) after suture fixation of posterior chamber intraocular lens implantation.Retinal detachment developed due to perforation of the retina by the fixation needle in 3 eyes,and due to formation of retinal tears with vitreous traction in 11 eyes.Primary vitrectomy was performed in 8 eyes and scleral buckling in 6 eyes.Retinal reattachment was achieved in all eyes that underwent vitrectomy,however both eyes that underwent scleral buckling developed proliferative vitrectomy postoperatively necessitationg subsequent vitreous surgery.Postoperative visual acuities improver more than 5 eyes,remained unchanged in 6 eyes,and worsened more than 3 eyes.Conclusion Primary vitrectomy ap-peared to be effective in treating retinal detachment following suture fixation of posterior chamber intraocular lens implantation,because most of our cases were associated with strong vitreous traction.Such retinal detach-ments should be immediately treated due to the higher risk of developing proliferative vireoretinopathy with breakdown of the blood-retinal barrier.
