Sporadic zonular cataract found by scleral penetration

Abstract

Purpose: To present a case of bilateral zonular cataract without visual deterioration.

Observation: A 41-year-old Taiwanese Han male presented with severe left ocular pain after being hit by iron filings while working. The iron dust was removed in a local hospital but due to a scleral laceration diagnosis he was referred to our hospital for further management. On examination, best-corrected visual acuity (BCVA) of 20/25 in the right eye and 20/200 in the left eye were obtained, while the before BCVA was 20/25 in the both eyes. The slit-lamp biomicroscopy demonstrated bilateral zonular cataract and left scleral full-thickness laceration with vitreous prolapse. The scleral suture procedure was then performed smoothly and the patient discharged three days later with BCVA in the left eye recovered to 20/30.

Conclusion and importance: The bilateral zonular cataract without associated systemic disorder is a rare form, which may be found incidentally with no visual symptoms.
