Anterior rosette is seen in
A
Blunt trauma
B
Penetrating injury
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Several types of retinal changes can occur after blunt ocular trauma, including commotio retinae, choroidal rupture, subretinal haemorrhage, and macular hole. Previous studies have reported on the visual outcomes of eyes with acute blunt trauma5, 6.

Detailed explanation-2: -Combination of coup, contrecoup, and equatorial expansion is responsible for formation of traumatic cataract following blunt ocular injury. Penetrating trauma that directly compromises the lens capsule leads to cortical opacification at the site of injury.

Detailed explanation-3: -The cataracts presenting with petaloid/rosette-shaped opacifications are typically 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.
