Traumatic cataract

Case contributed by Dr Vinay V Belaval

Presentation

History of blunt trauma to left orbit 2 months back. Reduced vision in the left eye since then.

Patient Data

Age: 20 years
Gender: Male
CT

Plain CT scan of orbits shows reduced density of left intraocular lens (48 HU) as compared to the right (90 HU) with indistinct outlines. No calcifications.

Contours of both eye-globes are maintained. Bony orbital walls are intact.

These features in the setting of prior recent trauma and reduced vision, are consistent with a traumatic cataract of the left eye.

Annotated image

Annotated magnified axial image of both orbits at the level of lens reveal reduced density of left lens as compared to right, consistent with traumatic cataract.

Case Discussion

Traumatic cataracts are diagnosed by reduced density of intraocular lens on CT scan. Mature cataracts can undergo calcifications.

Reduced density of the lens is thought to be due to the seepage of water into lens secondary to traumatic capsular tear, resulting in edema of lens and cataract formation.
