Lens Displacement and Retinal Injury in Blunt Eye Trauma

Introduction: We aimed to investigate the incidence and prognosis of retinal injury in patients with lens dislocation caused by blunt eye trauma. Methods: We retrospectively analyzed 53 patients who underwent lensectomy and vitrectomy for contusive lens dislocation and had no preoperative retinal injuries. Patients were categorized according to the presence of retinal injury discovered intraoperatively. The clinical features of 53 eyes were assessed during a 3-month postoperative follow-up. Results: Retinal injuries were observed intraoperatively in 28 patients (52.8%), predominantly in peripheral regions, with a single retinal tear being the most common type. Total lens dislocation was more frequent than subluxation in the group with retinal injuries. The intraocular pressure (IOP) at the 3-month follow-up was significantly lower than the initial IOP in both groups, with no significant differences between them. The corrected distance visual acuity (CDVA) significantly improved in both groups without significant differences. Conclusion: Half of the patients without preoperative retinal injuries were found to have injuries during surgery. Total lens dislocation carried a greater risk of retinal injuries than subluxation. The improvement in CDVA after prompt retinal injury treatment did not significantly differ from that in patients without retinal injury, highlighting the importance of prompt intervention.
