Anterior dislocation of a sulcus fixated posterior chamber intraocular lens in a high myope

Traumatic superio-nasal subconjunctival dislocation of posterior chamber intraocular lens. A case report

Introduction and importance

Intraocular lens (IOL) implantation after cataract surgery is routine procedure. Traumatic dislocation of the posterior chamber IOL into the subconjunctival space following blunt ocular trauma is rare and it is considered an ophthalmic emergency.

Case presentation

We present a case of a 71-year-old male that presented to our institution with traumatic dislocation of a posterior chamber IOL into the superior-nasal subconjunctival space following blunt trauma to his left eye after an accidental fall on his head.

Discussion

Trauma in a pseduphakic eye can be devastating. Early recognition and treatment of IOL dislocation are of paramount importance to prevent further damage and infections. Half ring sign (Psudophacocele) recognition help in identifying and localizing the dislocated IOL in subconjunctival space.

Conclusion

Traumatic dislocation of posterior chamber IOLs have been rarely reported in the literature. Nevertheless, it could happen years after implantation.

•

Dislocation of IOL into the subconjunctival space is rare, yet an ocular emergency.

•

Blunt ocular trauma has a devastating sequalae in a psudophakic eye.

•

Trauma severity is an important factor for intraocular lens dislocation.

Inferior subconjunctival dislocation of posterior chamber intraocular lens after blunt trauma

Traumatic subconjunctival dislocation of the posterior chamber intraocular lens (PCIOL) is a rare and emergency condition. Here, we report an interesting variation of rare case of inferior subconjuctival dislocation of PCIOL in a 75-year-old female patient following blunt trauma to her right eye with cow's head. All the previous literature with subconjuctival dislocation of PCIOL has reported the superior dislocation of intraocular lens. Inferior subconjunctival dislocation has never been reported in previous literature.
