Weekend Bytes - Rosette Cataract!



-Petaloid/rosette-shaped opacifications are seen in patients who have sustained blunt or penetrating physical trauma to the eye, and rarely due to electric shock, exposure to infrared energy or ionising radiation.

-The force of the blunt trauma may result in coup, contrecoup injury or axial expansion of the lens.

-The coup ocular injury is a result of direct impact, and results in formation of a Vossius ring as a consequence of compression of the pigmented posterior iris epithelial cells against the anterior lens capsule.

-The contrecoup injury generates shock waves along the line of impact of trauma, and may result in posterior cortical opacification in rosette or stellate shape.

-The axial expansion causes rapid anterioposterior expansion and may disrupt the lens capsule and/or zonules.

-These opacifications may appear immediately after, or even up to few months after the trauma.
