Subconjunctival lens dislocation

Abstract

In their article on patients with subconjunctival crystalline lens dislocation secondary to blunt ocular trauma,1 Yurdakul and coauthors observed that all patients reported to have subconjunctival lens dislocation to date, including theirs, were older than 40 years and attributed this to the presence of a hard lens and rigid sclera as apparent prerequisites for the subconjunctival dislocation. We reported a case of posttraumatic subconjunctival dislocation of the lens and its successful management in a 16-year-old patient.2 The patient had Ehlers-Danlos syndrome type VI, and the defective collagen synthesis and susceptibility to trauma in this condition seem to be the reason for the young age at presentation. Other differences between our case and other reported cases were the unusual inferonasal subconjunctival dislocation of the lens and the long period (90 days) that the dislocated lens remained intact subconjunctivally without being absorbed. Previously, the longest duration was 2 months.3 We believe the underlying connective tissue disorder and the young age of the patient explain the findings. Yurdakul and coauthors rightly conclude that with timely intervention, the visual outcome is reasonably good.
