Traumatic cataract
Diagnosis probable
Updates to Case Attributes
Presentation
was changed:
History of blunt trauma to left orbit 2 months back. Reduced vision in the left eye since then.
Age
changed from 22 years to 20 years.
Diagnostic Certainty
was set to
.
Body
was changed:
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 edemaoedema of lens and cataract formation.

Updates to Study Attributes
Findings
was changed:
Plain CT scan of orbits showshows reduced density of left intraocular lens (48 HU) as compared to the right intraocular lens (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.
