  • Title: Visual results, prognostic indicators, and posterior segment findings following surgery for cataract/lens subluxation-dislocation secondary to ocular contusion injuries.
    Author: Greven CM, Collins AS, Slusher MM, Weaver RG.
    Journal: Retina; 2002 Oct; 22(5):575-80. PubMed ID: 12441722.
    Abstract:
    OBJECTIVE: To determine visual outcomes, incidence of posterior segment abnormalities, and prognostic factors in eyes undergoing lens removal for cataract or lens subluxation-dislocation secondary to ocular contusion injuries. DESIGN: Retrospective, noncomparative, interventional case series. PARTICIPANTS: Forty eyes in forty consecutive patients undergoing lens extraction for ocular contusion-related cataract or lens subluxation, all with a minimum of 6 months' follow-up. INTERVENTION: Lens extraction in the traumatized eye. MAIN OUTCOME MEASURE: Final best-corrected visual acuity. RESULTS: Final best-corrected visual acuity was 20/40 or better in 55% of eyes, and ambulatory vision (>5/200) was achieved in 88%. Preoperative factors associated with poorer visual outcome (<20/40) were the presence of an afferent pupillary defect or an iridodialysis (P < 0.05). Seventy percent of eyes were determined to have significant posterior segment injuries. The cause of final visual acuity less than 20/40 included macular scarring (23%), retinal detachment (15%), and optic atrophy (5%). CONCLUSION: Cataract or lens subluxation secondary to ocular contusion injuries is often associated with severe posterior segment sequelae and poor visual outcomes.
