Although retinal detachment has been reported in association with sutured posterior chamber intraocular lenses (PCIOL), detailed analysis of the pathogenesis, clinical features and risk factors is lacking. Thirty-nine patients who had undergone surgery for scleral-sutured PCIOL were therefore reviewed, revealing 8 patients with associated retinal tears or detachments. Retinal breaks resulted from vitreous incarceration by the intraocular suture (6), post-operative vitreous detachment (1), preretinal manipulation of the dislocated PCIOL (1), surgical entry-sites (1) and surgical induction of posterior vitreous detachment (1). An axial length > 25 mm was associated with the development of retinal tears (p < 0.05, Fisher's exact test). All patients had attached retina with median visual acuity of 6/12 (range 6/6 to CF) at last follow-up (median 15 months, range 1-41 months). In patients requiring a pars plana approach, careful attention to the posterior hyaloid face, basal gel, surgical entry-sites and suture tract is recommended to reduce the risk of retinal detachment associated with scleral-sutured PCIOL procedures.
